I have trouble when trying to compile& run IPM on an SGI Altix cluster.
The issue is: this cluster is providing a default SGI MPT
implementation of MPI,
but I want to use a private installation of OpenMPI 1.4.3 instead.
1) When I compile IPM as recommended, everything works fine, but, clearly
the shared lib which is built is aiming at the default SGI-MPT install.
The configure command line was:
./configure --with-compiler=INTEL --prefix=/home/myhome/ipm/ipmoicc/ipm
2) When trying to run the application with the relevant LD_PRELOAD, this
mpiexec: symbol lookup error:
/home/myhome/ipm/ipmoicc/ipm/lib/libipm.so: undefined symbol:
leading to the diagnostic above.
3) Of course, if one forces the linking of the application with -lipm,
the same kind of culprit is found:
undefined reference to « mpi_sgi_status_ignore »
My feeling is I am missing the right way to make IPM pointing at my
private install of OpenMPI
at IPM compile time. How to achieve this, please ? I found no indication
on the Web, unfortunately, looking MPI or IPM ways :-)
Thanks in advance for any hint, Regards, G.
