[Info-vax] Multiprocessor VAX (simh extension) & pthreads

[Eberhard Heuser]

Hi,

I want to test some pthreads code.

Because of the lack of a multiprocessor alpha or vax machine I try to use the multiprocessor vax emulator extension.

I manage to start a 4 processor system (show cpu says this) but a pthreads program seems to run only on one processor: 

I see no speedup if I raise the number of threads.

On my I64 VMS machine the speedup is definitely there so the c-code seems to be OK.

Any ideas how solve this problem?
