Re: [ptp-user] error while loading shared libraries: libimf.so: cannot open shared object file: No such file or directory

Hi David,
 
I grabbed the LD_LIBRARY_PATH value from the server, and put that as you advised.
 
Here is the script produced by Eclipse:
 
#!/bin/bash
#SBATCH --workdir=/home/sha264/mpi_test
#SBATCH --job-name=ptp_sbatch
#SBATCH --nodes=2
#SBATCH --partition=debug
#SBATCH --time=00:01:00
export LD_LIBRARY_PATH="/share/cluster/RHEL6.2/x86_64/apps/openmpi/1.6.2/lib:/share/cluster/RHEL6.2/x86_64/apps/intel/ict/composer_xe_2013.0.079/compiler/lib/intel64:/share/cluster/RHEL6.2/x86_64/apps/intel/ict/composer_xe_2013.0.079/mkl/lib/intel64"
# Set mpirun arguments
NP="-np 4"
CWD="-cwd /home/sha264/mpi_test"
if [ "" = "--reboot" ]; then
    REBOOT="-reboot"
fi
MPI_ARGS="${NP} ${MODE} ${CWD} ${MAPFILE} ${LABEL} ${REBOOT} ${VERBOSE} ${TRACE} ${CONFIG}"
# Set mpirun environment variables
MPI_ENV="-env_all"
COMMAND="mpirun ${MPI_ARGS} ${MPI_ENV} /home/sha264/mpi_test/hello "
cd /home/sha264/mpi_test
${COMMAND}
BTW, Eclipse complains:
 
Problem Occurred
'Launching DLXHello' has encountered a problem.
sbatch Exited with value: 1
sbatch: error: Batch job submission failed: Node count
specification invalid
Job Submit Failed
 
Do you have any advice?
 
BTW, the working script I wrote manually looks like:
 

#!/bin/bash

#SBATCH -n 4

#SBATCH -t 00:01:00

#SBATCH -J hello_job

#SBATCH -o output.txt

mpirun hello

 

Any idea?

 

Thanks,

 

Hamid

Hello List,
 
I am running Eclipse and PTP on Windows and trying to develop a remote MPI project. So far, I could compile my hello world C file and get the executable. BTW, I couldn't have been able to run the executable on the remote server. I keep receiving:
 

mpirun: error while loading shared libraries: libimf.so: cannot open shared object file: No such file or directory

 

which is related to the PATH environment variable. Looking online resources, I am advised to set the LD_LIBRARY_PATH. However, I don't know where on Eclipse I should set that and to what value should it be set. I appreciate your help.

 

Thank you.

It looks like libimf.so is an Intel library so you need to find the directory containing that library, for instance /opt/intel/composer_xe_2013_sp1.1.106/compiler/lib/intel64/libimf.so, and add it to the setting for LD_LIBRARY_PATH.

LD_LIBRARY_PATH can be set in the Environment tab of the run configuration for your application by clicking the New button, filling in the Name field with LD_LIBRARY_PATH and the Value field with what you would specify as your complete library search path

It looks like this fixed the problem finding the library. Unfortunately I don't know anything about SLURM, which I think is the batch scheduler you are using, based on a google search for the sbatch command.

All I could find, by search for the sbatch 'Node count specification invalid' message, was that there's some problem with how you are specifying nodes. The page I found suggests you are asking for more nodes than are available, but I don't know if that's the only reason for the message.

Others on the PTP team might be more knowledgeable about SLURM and might be able to help.
