Linux Fluent HPC parallel system check failed
 

Dears,

I am trying to run fluent from Master Node Linux Cluster in order to spawn node01 and it is failing with errors:

fluent
/ansys_inc/v140/fluent/fluent14.0.0/bin/fluent -r14.0.0
/ansys_inc/v140/fluent/fluent14.0.0/bin/fluent -r14.0.0 3d -t4 -pinfiniband -mpi=openmpi -cnf=/gpfs1/iaf04/.fluent.launcher.host -ssh
bash: /ansys_inc/v140/fluent/fluent14.0.0/multiport/mpi_wrapper/bin/mpicheck.fl: No such file or directory
*** Parallel system check failed!
*** To disable this check, run FLUENT with -pcheck=0
/ansys_inc/v140/fluent/fluent14.0.0/cortex/lnamd64/cortex.14.0.0 -f fluent -newcx (fluent "3d -host -alnamd64 -r14.0.0 -t4 -cnf=/gpfs1/iaf04/.fluent.launcher.host -path/ansys_inc/v140/fluent -ssh")
[iaf04@hpc-mgt1 ~]$ fluent

we have inifiniband - with openmpi and password-less ssh access with shared home folder.

Also I have noticed that I get cortexerror.log in my home folder and its content is:

==================

When specifiying Parallel on same machine MasterNode for example it works. But does not work when specifying node01.

any ideas why mpi are not communicating?

Hi,
Did you solve this? I am also trying to run fluent in HPC server with PBS Pro job scheduler.
