Subject: Re: [OMPI users] PathScale problems persist

I am using GCC 4.x:

$ pathCC -v
PathScale(TM) Compiler Suite: Version 3.2
Built on: 2008-06-16 16:41:38 -0700
Thread model: posix
GNU gcc version 4.2.0 (PathScale 3.2 driver)

$ pathCC -show-defaults
Optimization level and compilation target:
   -O2 -mcpu=opteron -m64 -msse -msse2 -mno-sse3 -mno-3dnow -mno-sse4a
-gnu4

And I also tried with mpiCC -gnu4 to be totally sure. It's rather weird
that I get this error and Ake does not...

I configured Open MPI with PathScale with the following line, by the
way:

./configure --with-openib=/usr --with-openib-libdir=/usr/lib64
--with-sge --enable-static CC=pathcc CXX=pathCC F77=pathf90 F90=pathf90
FC=pathf90

And with GCC:

./configure --with-openib=/usr --with-openib-libdir=/usr/lib64
--with-sge --enable-static

It's not an Infiniband or SGE issue. I also tried with all processes
running on the same node and without SGE.

Best regards,

Rafa
