[mpich-discuss] Problem with MPICH3/OpenPA on IBM P755

[Victor Vysotskiy]

Hi, 

I am trying to compile the latest ('v3.2a2-24-g4ad367d0') nightly snapshot on the IBM P775 machine. The MPICH3 is configured with the following options:

export OBJECT_MODE=64
./configure  --enable-f77 --enable-fc --enable-cxx --enable-smpcoll --with-thread-package=pthreads --with-pami=/opt/ibmhpc/pecurrent/ppe.pami --with-pami-lib=/opt/ibmhpc/pecurrent/ppe.pami/lib --with-pami-include=/opt/ibmhpc/pecurrent/ppe.pami/include64 --enable-mpe --enable-error-messages=all CC="xlc_r -q64 -qmaxmem=-1" CPP=/usr/ccs/lib/cpp CXX="xlC_r -q64 -qmaxmem=-1" F77="xlf_r -q64 -qmaxmem=-1" FC="xlf90_r -q64 -qmaxmem=-1" CFLAGS="-q64 -qmaxmem=-1" CXXFLAGS="-q64 -qmaxmem=-1" FCFLAGS="-qmaxmem=-1 -q64" FFLAGS="-q64 -qmaxmem=-1" OBJECT_MODE=64 AR="ar -X 64"   --with-file-system=bg+bglockless

No problem with compiling it, but there is a problem with running OpenPA tests:

***** 16 PRIMITIVES TESTS FAILED! *****

Apparently, a bunch of tests failed. Is there anything to worry about? Or, I can simply skip these failed test and can use the compiled MPICH3 for production?
 
The software stack used:
AIX v7.1.0.0
XLC/XLF compiler v14.01.0000.0008
POE v1-1.2.0.3

Best,
Victor.
