I am using a HPC
Apro green server
Centos 6.3 Linux based
256 core

I am trying to run Platform MPI - distributed Parallel

I get the follwing error :

" An error has occurred in cfx5solve:

A host list or host file is required for a Distributed Parallel run, but
none has been specified.


An error has occurred in cfx5solve:

Unable to find the master host sinbaram13.plsi.or.kr in the host list: at
least one partition must be assigned to the master host. "

My script file is following :

#! /bin/ksh
#@ job_name = ssh

#@ job_type = MPICH
#@ class = engineering
#@ output = ssh.out

#@ error = ssh.err
#@ notification = complete

#@ notify_user = @gmail.com

#@ resources = ConsumableCpus (1) ConsumableMemory(2gb)

#@ wall_clock_limit =72:00:00

#@ total_tasks =32

#@ blocking =unlimited

#@ initialdir =/scratch2/

#@ queue

. /applic/Applications/env_setup/cfx_v150.env

nodes=`cat $LOADL_HOSTFILE`
nodes=`echo $nodes | sed -e 's/ /,/g'`

export CFX5RSH=ssh

cfx5solve -mdef CFX.mdef -start-method "Platform MPI Distributed Parallel"




Please help me in solving the following :

Try "Platform MPI Local Parallel" if one single computer node is enough for your problem, or if it must be distributed, from this discussion it appears to be a configuration problem. If necessary, please ask your system administrator to install and configure CFX distributed parallel. This section may be relevant for the install process in the case of version 16.2.3; it may be different for a different version.

From cfx5solve -help,

-start-method <name>
Use the named start method to start the ANSYS CFX Solver. This option
allows you to use different parallel methods, as listed in the
ANSYS CFX Solver Manager GUI or in the etc/start-methods.ccl file,
instead of the defaults. For parallel start methods, you must also
provide the -part or -par-dist option.
