The efficient solution of large problems is an ongoing thread of research in scientific computing. An increasingly popular method of solving these types of problems is to harness disparate computationa
l resources and use their aggregate power as if it were contained in a single machine. This mode of using computers that may be distributed in geography, as well as ownership, has been termed }{\i Distributed Computing}{
. Some of the major issues concerned with D
istributed Computing are resource discovery, resource allocation and resource management, fault-tolerance, security and access control, scalability, flexibility and performance. Various organizations have developed mechanisms that attempt to address these
 issues, each with their own perspectives of how to resolve them.

Various mechanisms have been developed to perform computations across diverse platforms. The most common mechanism involves software libraries. Unfortunately, the use of such li
braries presents several difficulties. Some software libraries are highly optimized for only certain platforms and do not provide a convenient interface to other computer systems. Other libraries demand considerable programming effort from the user. While
 
several tools have been developed to alleviate these difficulties, such tools themselves are usually available on only a limited number of computer systems and are rarely freely distributed. Matlab [matlab] and Mathematica [mathematica] are examples of su
ch tools.

The NetSolve project is being developed at the University of Tennessee's Computer Science Department. It provides remote access to computational resources, both hardware and software. Built upon standar
d Internet protocols, like TCP/IP sockets, it is available for all popular variants of the UNIX\'99 operating system, and parts of the system are available for the Microsoft Windows 95\'99, Windows 98\'99, Windows NT\'99, and Windows 2000\'99
 platforms. Testing has not yet been conducted on the Windows ME\'99 operating system.

The figure also shows the relation NetSolve has to the applications that use it. NetSolve and systems like it are often referred to as Grid Middleware; this figure helps to make the reason for this terminology clearer. The shaded parts of the 
figure represent the NetSolve system. It can be seen that NetSolve acts as a glue layer that brings the application or user together with the hardware and/or software it needs to complete useful tasks.
\par At the top tier, the NetSolve client library is linked
 in with the user's application. The application then makes calls to NetSolve's application programming interface (API) for specific services. Through the API, NetSolve client-users gain access to aggregate resources without the users needing to know anyt
hing about computer networking or distributed computing. In fact, the user does not even have to know remote resources are involved.
\par The NetSolve agent maintains a database of NetSolve servers along with their capabilities (hardware performance and allocate
d software) and dynamic usage statistics. It uses this information to allocate server resources for client requests. The agent finds servers that will service requests the quickest, balances the load amongst its servers and keeps track of failed ones.

\par The 
NetSolve server is a daemon process that awaits client requests. The server can run on single workstations, clusters of workstations, symmetric multi-processors or machines with massively parallel processors. A key component of the NetSolve server is a so
u
rce code generator which parses a NetSolve problem description file (PDF). This PDF contains information that allows the NetSolve system to create new modules and incorporate new functionalities. In essence, the PDF defines a wrapper that NetSolve uses to
 call functions being incorporated.
\par The (hidden) semantics of a NetSolve request are:

 a host running a NetSolve agent. The default NetSolve agent running at the University of Tennessee is aware of many servers that can perform the computation. In fact, a dense linear system solve is provided with the NetSolve distribution as default numer
ical software for the server. The user has now two possible courses of action to find out about the problem. Let us assume that the user chooses to use the UNIX command line management tools (see }{\field{\*\fldinst {  HYPERLINK  \\l ID_TOOLS}{

From the user's point of view, the call to NetSolve is exactly equivalent to a call to LAPACK. One detail, however, needs to be mentioned. Most numerical software is written in Fortra
n77 and requires users to provide workspace arrays as well as data, since there is no possibility for dynamic memory allocation. Because we preserved the exact calling sequence of the numerical software, we require the user to pass those arrays. But, sinc

 the computation is performed remotely, workspace on the client side is meaningless. It will, in fact, be dynamically created on the server side. Therefore, when the numerical software would require workspace, the NetSolve user may provide a one-length ar

Farming is a new way of calling NetSolve to manage large numbers of requests for a single NetSolve problem. Many NetSolve users are confronted by situations when many somewhat similar computations must be performed in parallel. Previously, the way to do t
his in NetSolve was to write non-blocking calls to }{\f2\fs21 netslnb()}{
 in C for instance. However, this becomes very cumbersome. Not only because the user must manage all of the requests himself, but also because the NetSolve system is at a loss trying to manage such
 a large number of requests without flooding the servers. This is the motivation for distributing a new call in NetSolve: }{\f2\fs21 netsl_farm()}{
. In the present distribution, this call is only available from C, but will soon be made available from Matlab, Mathematic
a, and Java. A Fortran interface will most likely not be provided because of pointer management. For now, linking to the C NetSolve client library (generated as explained in }{\field{\*\fldinst {  HYPERLINK  \\l ID_DOWNLOADING}{{\*\datafield

 farming algorithm avoids this problem by dynamically tuning the maximum number of pending requests to reflect changes in the computational server pool (size and load). This is done by constantly measuring the throughput of the computations.

 the tasks and their execution dependences. This DAG is then sent to a server in the system where it is scheduled for execution. More details regarding this interface and some results can be found in [sequencing].

 computational modules or NetSolve services and the arcs represent data dependencies amongst these modules. The graph is acyclic because looping control structures are not allowed within the sequence, and therefore, a node can never be its own descendant.

10.1. Introduction
\par }\pard\plain \ql \li960\ri0\sb207\sl312\slmult0\widctlpar\hyphpar0\faauto\rin0\lin960\itap0 \fs24\lang1033\langfe1033\cgrid\langnp1033\langfenp1033 {
This is the first version of NetSolve with (rudimentary) Kerberos support. NetSolve components include clients, agents, and servers. Currently the only requests that require authentication are requests that the client makes to the server, and of those, on
l
y the ``run problem'' request. Other requests could be authenticated (an obvious one being ``kill server''), but drastic changes along these lines would probably require drastic restructuring of NetSolve. For instance, a client can currently inform an age
n
t that a particular server is down, and the agent will not advertise that server for use in other problems. It seems of dubious value to require authentication for such requests until there is a mechanism for specifying the trust relationship between clie
nts and agents.
\par }\pard \ql \li960\ri0\sb120\sl312\slmult0\widctlpar\hyphpar0\faauto\rin0\lin960\itap0 {
An attempt has been made to allow Kerberized NetSolve clients to interoperate with both Kerberized and non-Kerberized NetSolve servers. In either case the client sends a request to the server. An ordinary server will return a status code ind
icating that he will accept the requested operation. By contrast, a Kerberized server will immediately return an ``authentication required'' error in response to the request. The client is then required to send Kerberos credentials to the server before th
e
 request will be processed. This allows the server to require authentication of the client. Currently there is no mechanism to allow the client to insist on authentication of the server - a Kerberized client will happily talk with either Kerberized or non
-Kerberized servers.
\par The server implements access control via a simple list of Kerberos principal names. This list is kept in a text file which is consulted by the server. A request to a NetSolve server must be made on behalf of one of those principal names
. If the principal name associated with the Kerberos credentials in the request appears in the list, and the credentials are otherwise valid, the request will be honored. Otherwise, the request will be denied.
\par Since the NetSolve server was not designed to 
run as a set-uid program, it is not currently feasible to have the NetSolve server run processes using the user-id of the particular UNIX user who submitted the request. NetSolve thus uses its own service principal name of ``netsolve'' rather than using t
he ``host'' principal. What this means (among other things) is that you need to generate service principals and keytabs for each of your NetSolve servers, even if you already have host principals in place.
\par The NetSolve server, by default, runs in non-Kerberized mode. To start up the server in Kerberized mode you need to add the }{\b\f2 -k}{
 option to the command-line, and also set environment variables NETSOLVE_KEYTAB (pointing to the keytab) and NETSOLVE_USERS pointing to the list of authorized users).
\par This version of Kerberized NetSolve performs no encryption of the data exchanged among NetSolve clients, servers, or agents. Nor is there any integrity protection for the data stream.

In the preceding sections, we described all the client interfaces to NetSolve. In these descriptions we assumed that the only input the user had to supply to NetSolve was numerical data, that is, matrices, vectors, or scalars. This assumption is valid for
 a lot of numerical software. However, for some software that we would like to include in NetSolve via NetSolve servers, we need an additional feature. Indeed, numerous scientific packages require the user to provide numerical data as well as a }{\i 
function}{. Ty
pically, nonlinear software requires the user to pass a pointer to a subroutine that computes the nonlinear function. This is a problem in NetSolve because the computation is performed remotely and the user cannot provide NetSolve with a pointer to one of
 his linked-in subroutines. The only solution is to send code over the network to the server. This approach raises a lot of issues, including }{\i security}{.

t, and there is definitely room for improvement. However, we believe that it provides reasonable capabilities for now, considering that NetSolve is still at an early stage of development. As we noted, we need to ship code over to the computational server.
 
Since NetSolve works in a heterogeneous environment, it is not possible to migrate compiled code. Thus, we require that the user have his subroutine or function in a separate file, written either in C or Fortran. We send this file to the computational ser
ver. The server compiles it and is then able to use this user-supplied function.

 UNIX command to disallow any system call. The approach is very restrictive for the user, but typically the subroutine that has to be passed needs only to perform computations. If course, there are a lot of }{\i hacker}{
 ways to go around this problem, and our system currently does not pretend to be a real security manager. We are investigating Java to deal with this user-supplied function issue.

This new feature of NetSolve is still under investigation. We are aware that security is an important issue here. For now, NetSolve is still a research project developed to allow experimentations with this
 relatively new type of software. In the future, more attention will be given to the user-supplied mechanism in order to make it as safe as possible. As mentioned earlier, we may use Java in order to set up a viable security manager. Using Java currently 
a
ppears to be the best solution for security, but it has obvious drawbacks. First, the user would have to write his function in Java: the typical NetSolve user is a scientist who does not have the time or inclination to learn new languages, especially obje
ct-oriented ones. Second, with the current implementations of Java, efficiency would also be a problem.

It is possible to add new functionalities to a NetSolve computational server by specifying additional problem description files in the server configuration file. In fact, a
 number of PDFs have been written for a variety of serial and parallel software packages: ARPACK, Aztec, BLAS, ITPACK, LAPACK, MA28, PETSc, ScaLAPACK, and SuperLU. These PDFs are available in the }{\f2\fs21 $NETSOLVE_ROOT/problems/}{

 NetSolve uses the Compressed Row Storage (CRS) for storing sparse matrices. The Compressed Row Storage (CRS) format puts the subsequent nonzeros of the matrix r
ows in contiguous memory locations. Assuming we have a nonsymmetric sparse matrix, we create vectors: one for floating-point numbers (val), and the other two for integers (col_ind, row_ptr). The val vector stores the values of the nonzero elements of the 
matrix, as they are traversed in a row-wise fashion. The col_ind vector stores the column indexes of the elements in the val vector. The row_ptr vector stores the locations in the val vector that start a row.

$NETSOLVE_ROOT/bin/$NETSOLVE_ARCH}{ directory. After this compilation, you can also find a shell script named }{\b NS_pdgui}{
 that can be used from any directory to properly run the GUI application which needs to locate the abovementioned classfiles. This GUI can be used to create and load PDFs into NetSolve. Apart from being easy to use, the GUI also has a help menu (not imple
m
ented yet) and we defer other details about running the GUI to those help files. The user has the option of storing PDFs in nspdf format or both nspdf format and xmlpdf format. The user can only load a PDF if it has been stored in xmlpdf format. As the us
er has the option of storing in xmlpdf format, there is no need to keep the GUI open until he gets the pdf correct. He must make sure that he has stored the created pdf in xmlpdf format before closing the GUI.

18.1. Introduction

nts, and servers. Currently the only requests that require authentication are requests that the client makes to the server, and of those, only the ``run problem'' request. Other requests could be authenticated (an obvious one being ``kill server''), but d
r
astic changes along these lines would probably require drastic restructuring of NetSolve. For instance, a client can currently inform an agent that a particular server is down, and the agent will not advertise that server for use in other problems. It see
ms of dubious value to require authentication for such requests until there is a mechanism for specifying the trust relationship between clients and agents.
\par }\pard \ql \li960\ri0\sb120\sl312\slmult0\widctlpar\hyphpar0\faauto\rin0\lin960\itap0 {An attempt has been made to allow Kerberized NetSolve clients to interoperate with both Kerberized a
nd non-Kerberized NetSolve servers. In either case the client sends a request to the server.An ordinary server will return a status code indicating that he will accept the requested operation. By contrast, a Kerberized server will immediately return an ``
a
uthentication required'' error in response to the request. The client is then required to send Kerberos credentials to the server before the request will be processed. This allows the server to require authentication of the client. Currently there is no m
echanism to allow the client to insist on authentication of the server - a Kerberized client will happily talk with either Kerberized or non-Kerberized servers.
\par The server implements access control via a simple list of Kerberos principal names. This list is
 kept in a text file which is consulted by the server. A request to a NetSolve server must be made on behalf of one of those principal names. If the principal name associated with the Kerberos credentials in the request appears in the list, and the creden
tials are otherwise valid, the request will be honored. Otherwise, the request will be denied.
\par Since the NetSolve server was not designed to run as a set-uid program, it is not currently feasible to have the NetSolve server run processes using the user-id o
f the particular UNIX user who submitted the request. NetSolve thus uses its own service principal name of ``netsolve'' rather than using the ``host'' principal. What this means (among other things) is that you need to generate service principals and keyt
abs for each of your NetSolve servers, even if you already have host principals in place.
\par The NetSolve server, by default, runs in non-Kerberized mode. To start up the server in Kerberized mode you need to add the }{\b\f2 -k}{ option to the command-line, and also set
 environment variables NETSOLVE_KEYTAB (pointing to the keytab) and NETSOLVE_USERS pointing to the list of authorized users).
\par This version of Kerberized NetSolve performs no encryption of the data exchanged among NetSolve clients, servers, or agents. Nor is there any integrity protection for the data stream.

In NetSolve, as in other metacomputing systems, the scheduling of tasks to available resources is difficult. NetSolve uses a limited load-balancing strategy to improve the utilization of computational resources. This load-balancing strategy takes into acc
o
unt the current workload of the computational resources available in the NetSolve system. In scheduling the client's requests over a network, the workload estimate should be ``forecast'' for when the computation will execute, and not a workload estimate o
b
tained at a time prior to the request. There are also other characteristics of distributed metacomputing resources such as the CPU speed of the resource, the amount of physical memory of the resource, as well as the latency/bandwidth from the client to th
e computational resource, that can be effectively utilized in scheduling decisions for the computational resources.

here it will have full knowledge of the computational resources and be visible to all components of the NetSolve system. The Netsolve agent is the ``brain'' of the NetSolve system, knowing how many resources exist and where they are located, and making al

The Distributed Storage Infrastructure (DSI) in NetSolve1.4 is a new feature added to NetSolve. It is a first attempt toward
s achieving coscheduling of the computation and data movement over the NetSolve Grid. The DSI APIs help the user in controlling the placement of data that will be accessed by a NetSolve service. This is useful in situations where a given service accesses 
a
 single block of data a number of times. Instead of multiple transmissions of the same data from the client to the server, the DSI feature helps to transfer the data from the client to a storage server just once, and relatively cheap multiple transmission
s
 from the storage server to the computational server. Thus the present DSI feature helps NetSolve to operate in a cache-like setting. Presently, only Internet Backplane Protocol (IBP) is used for providing the storage service. In the future, we hope to in
tegrate other commonly available storage service systems.
