Linpack crashes with ACML on Windows Server 2008 R2

Discussion created by wipamit on Oct 4, 2010

I have built HPL with acml library version 4.4.0 for Win64 platform. I am launching HPL with mpirun.

It is working fine on Windows Server 2003 and Windows Server 2008.

But when i am launching it in similar way in Windows Server 2008 R2 edition, my application crashes and shows the below message:



Problem Event Name: APPCRASH

I am able to reproduce it by executing the following statement in a .bat file:

bin\mpirun.exe  -np 2  -stdio=bline,r3,p hpLinpackACML.exe

Just to verify if mpirun is working fine, i changed the value of -np to 1 in place of 2.

Is there a multithreading issue with ACML library. May be some in compatibility with Windows Server 2008 R2 edition.

Please update.

Thanks in Advance
