Hmm. That's not a good sign. OPA's configure seems to think that it can use some inbuilt atomic capability while the compiler/hardware is clearly not supporting it. Can you send us the OPA config.log (src/openpa/config.log) so we can look into it? Also cc'ed the IBM folks. IBM folks, any thoughts? -- Pavan

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:

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. _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
