Greetings comp.programming.threads folks,

My setup: Suse 9.3 w/nptl v2.3.4 on a (single) opteron box.
Hopefully a simple question:  I have a large (actually ~4GB) global array of
chars I would like multiple threads to only read.  Is the use of any
mutexes/locks/sync mechanisms required for this?  The array is fully
initialized before any thread creation.

Side question:  What C++ thread object library would you recommend?  I'm
looking at ZThread and Boost.

Thanks for any suggestions/input.

Best,
..Ken
