Thanks Jeff,
Things are better with 1.0.2a9. However open-mpi is not functional as yet.
- My new build script:
#! /bin/tcsh -v
setenv CC "cc"
setenv CXX "CC"
setenv F77 "f77"
setenv FC "f95"
setenv CFLAGS "-O -xtarget=opteron -xarch=amd64"
setenv CXXFLAGS "-O -xtarget=opteron -xarch=amd64"
setenv FCFLAGS "-O -xtarget=opteron -xarch=amd64"
setenv FFLAGS "-O -xtarget=opteron -xarch=amd64"
setenv LD "ld -64"
setenv LDFLAGS "-xtarget=opteron -xarch=amd64"
setenv CXXLDFLAGS "-xtarget=opteron -xarch=amd64"
./configure --prefix=/users/valiron/lib/openmpi-1.0.2a9
gmake
# gmake install
- Configure went through with no errors
- Make completed nicely, excepted compiling ompi/mpi/f90/mpi.f90 which
took nearly half an hour to complete. I suspect the optimization flags
in FFLAGS are not important for applications, and I could use -O0 or -O1
instead.
- I could compile/link a small piece of code (rotate.f)
valiron_at_icare ~/config > mpif77 -xtarget=opteron -xarch=amd64 rotate.f

- However the resulting executable fails to launch:
valiron_at_icare ~/config > mpirun --prefix
/users/valiron/lib/openmpi-1.0.2a9 -np 2 a.out
Segmentation fault (core dumped)
- The problem seems buried into open-mpi:
valiron_at_icare ~/config > pstack core
core 'core' of 27996: mpirun --prefix

What additional info could help to track the problem ?
Pierre.
