Executable for SPMD

Altair Forum User

Hello,

in the manual the following file path was given for the executable for Launching OptiStruct SPMD on Linux Machines using Direct calls to Executable:

$ALTAIR_HOME/hwsolvers/optistruct/bin/linux64/optistruct_spmd

In my Linux Installation, I only have these files in the folder:

EXB_API_Error.xml
optistruct_13.0_linux64
optistruct_13.0_linux64_cuda
optistruct_13.0_linux64_impi
optistruct_13.0_linux64_impi_tester
optistruct_13.0_linux64_pl8mpi
optistruct_13.0_linux64_plmpi
ossmooth_linux64

which one is the correct one?

Regards,

jope

Hi Jope

Try with plmpi instead.

$ALTAIR_HOME/hwsolvers/optistruct/bin/linux64/optistruct_13.0_linux64_plmpi

Thanks for your response.

I tried to start an mpi run with two methods, both leading to some problems shown below. Any ideas how to get it to work?

mpirun -np 16 /HyperWorks/13.0/altair/hwsolvers/optistruct/bin/linux64/optistruct_13.0_linux64_plmpi ***.fem -ddmmode

This resulted in:

/HyperWorks/13.0/altair/hwsolvers/optistruct/bin/linux64/optistruct_13.0_linux64_plmpi: error while loading shared libraries: libmpi.so.1: cannot open shared object file: No such file or directory

/HyperWorks/13.0/altair/scripts/optistruct -mpi i -np 16 ***.fem -testmpi

This resulted in:

ERROR in hwsolver script execution:
No useful executable found in:
/HyperWorks/13.0/altair/hwsolvers/optistruct/bin/linux64

You have not MPI library. For each MPI library: Intel MPI, Platform PMI, OpenMPI,... you have to correctly load the libmpi file. In general, it will done by run script.
