Hello everyone,

I'm testing my new cluster installation with the hpcc benchmark and
openmpi 1.2.1 on RHEL5 32 bit. I have some trouble with using a
threaded BLAS implementation. I have tried ATLAS 3.7.30 compiled with
pthread support. It crashes as reported here:
http://sourceforge.net/tracker/index.php?func=detail&aid=1708575&group_id=23725&atid=379483

If I link to the ATLAS version without pthread support hpcc runs fine.

I have a problem with Goto BLAS 1.14 too, the output of hpcc stops
before the HPL run, then the hpcc processes seem to do nothing,
consuming 100% CPU. If I set the maximum number of threads for Goto
BLAS to 1, hpcc is working fine again.

openmpi was compiled without thread support.

Can you give me a hint?

Regards, Götz Waschk
