This errata file lists errata for the ScaLAPACK Users' Guide and errata for the ScaLAPACK code itself. It also lists machine-specific installation hints, details of the updates, and any outstanding bugs to be fixed in the upcoming release.
This file contains:
ScaLAPACK has been tested on a variety of architectures. However, keep in mind that we do not have access to every possible type of machine, and the regrettable bug report will appear. We apologize for any inconvenience this may cause to our users, and strongly encourage users to contact us if you suspect an abnormality. Please contribute "machine-specific installation hints" for architectures that we do not have listed. These "hints" are of great benefit to many users.

8: Change to netlib format ( .tar.gz --> .tgz )
Section 1.7 change scalapack.tar.gz -> scalapack.tgz
9: Change to netlib format ( .tar.gz --> .tgz )
Section 1.8 change manpages.tar.gz -> manpages.tgz
13-14: Change to netlib format ( .tar.gz --> .tgz )
Section 2.1, numerous references to .tar.gz files
must be replaced by .tgz
14: Change to netlib format ( .shar -> .tgz )
http://www.netlib.org/blas/blas.shar
should be changed to
http://www.netilb.org/blas/blas.tgz
and
sh blas.shar
should be changed to
gunzip -c blas.tgz | tar xvf -
20: Typographical error in the 8th row of the coefficient
matrix A. The 8th row is listed as
-s -c -a -l -a -p -a c k
and should be replaced by:
-s +c -a -l -a -p -a c k
Likewise, this correction must be propogated to the
8th row of Figure 2.1.
-s +c -a -l -a -p -a c k
72: Section 4.4.2
In the text beginning "Table 4.10 illustrates ...",
it erroneously says NB=3. This should be NB=8, as noted
in the caption of Table 4.10.
90: Section 4.6.7, third paragraph
inherit --> inherent
116: Erroneous use of BLAS instead of BLACS in the first sentence
of Section 5.4.1. The first sentence should say:
"Users should choose vendor-supplied BLACS optimized for their
computer; these BLACS will be the fastest BLACS implementation."
We have tested ScaLAPACK on heterogeneous clusters of workstations using pvm3.4 and mpich version 1.1, and on the IBM SP-2, Intel Paragon, SGI Power Challenge, SGI Origin 2000, and Cray T3E. We tested on the IBM SP-2 using IBM MPI, on the SGI Power Challenge and Origin 2000 using SGI MPI v3.0, and on the Cray T3E using Cray MPI (mpt.1.2.0.0.6beta). The workstations used were AIX46K, ALPHA, HPPA, LINUX, SGI64, SUN4, and SUN4SOL2.
*** !! IMPORTANT !! *********************************************
Note to PGF77 and NAGF90 compiler users: We have unconfirmed reports
of Fortran/C interoperability problems (string handling) with
ScaLAPACK on the nagf90 and pg77 compilers. Until this is resolved,
the user will have to avoid using these two compilers in conjunction
with ScaLAPACK and the BLACS.
*** !! IMPORTANT !! *********************************************
Also for the Cray T3E ONLY, the user must reset the defined size of an integer and a real in the ScaLAPACK Test Suite. Set the variable INTGSZ = 8, REALSZ = 8, and CPLXSZ = 16 in all SCALAPACK/TESTING/LIN/p*driver.f, SCALAPACK/TESTING/EIG/p*driver.f, SCALAPACK/TESTING/EIG/p*sepreq.f, SCALAPACK/TESTING/EIG/p*gsepreq.f, SCALAPACK/PBLAS/TESTING/p*tst.f, and SCALAPACK/PBLAS/TIMING/p*tim.f testing/timing programs! By default, INTGSZ = 4, REALSZ = 4, and CPLXSZ = 8 for all other architectures.
UPDATED: March 12, 2002
The following bug fixes have NOT yet been incorporated in a release/update of ScaLAPACK.
| DIRECTORY/ROUTINE | DATE POSTED (M/D/Y) | DESCRIPTION OF CHANGE |
| SCALAPACK/PBLAS/SRC/PBtools.h | 3/12/2002 | Comment out CSYMM reference (line 57) |
| SCALAPACK/SRC/psdbtrf.f | 3/12/2002 | Typo (DLACPY->SLACPY) in EXTERNAL declaration (line 374) |
SCALAPACK/PBLAS/SRC/pblas.h
Change "void fortran" to "void" and "int fortran" to "int". ??
SCALAPACK/SLmake.inc:
add -DNO_IEEE to CDEFS
add -dp to compilation flags
SCALAPACK/SRC/p?stein.f:
as first executable line, add:
onenrm = 0.0E0
SCALAPACK/SRC/p?latrz.f:
add
AII = ZERO
right after quick return so it is initialized on nodes that do not do
stuff in P_LARFG
SCALAPACK/SRC/p?labad.f:
comment out
IF( LOG10( LARGE ).GT.2000.D0 ) THEN
because T3E has IEEE hardware, but not arithmetic
SCALAPACK/SRC/pslaiect.c
as first line, add:
#define float double
SCALAPACK/PBLAS/SRC/pblas.h
in original file, move lines 92 and 93 to line 119 (:92,93mo119)
this moves the typedef for complex below the #define float double . .
at line 27, add:
#ifdef T3E
#define _MACH_ _T3D_
#endif
SCALAPACK/PBLAS/TESTING/p*tst.f:
Set REALSZ = 8 and CPLXSZ = 16!!
SCALAPACK/PBLAS/TIMING/p*tim.f:
Set REALSZ = 8 and CPLXSZ = 16!!
SCALAPACK/TESTING/LIN/p*driver.f:
Set INTGSZ = 8, REALSZ = 8, and CPLXSZ = 16!!
SCALAPACK/TESTING/EIG/p*driver.f:
Set INTGSZ = 8, REALSZ = 8, and CPLXSZ = 16!!

Set INTGSZ = 8, REALSZ = 8, and CPLXSZ = 16!!
SCALAPACK/TESTING/EIG/p*gsepreq.f:
Set INTGSZ = 8, REALSZ = 8, and CPLXSZ = 16!!
SCALAPACK/TESTING/EIG/p[c,z]sepsubtst.f:
change line 737 from:

$ vl+normwin*five*thresh*eps
SCALAPACK/TESTING/EIG/p[d,s]sepsubtst.f:
change line 714 from:
