H. J.,

I ran the program on the PC and a MIPS le NEC vr5432. It worked fine on
both machines.

I do not run the pthread library on the SGI site because it dead locks.
I rebuilt the pthread lib natively on my MIPS box and use that lib in
place of the lib provided in the RPM on the SGI site.
(I suspect it is a cross compilation problem rather than a problem in
the pthread lib.)

I believe others have also posted about deadlocks with the pthread lib
on the SGI site.
