Hi,
I have a parallelized code that works fine on my local computer with the
command
$mpirun -n 5 python parallel_simulation.py
but when I try the same code on cluster I only get one process and it is not
running in parallel. I have both mpich and openmpi loaded on my cluster.
I tried to use
$mpirun -n 5 -hostfile /etc/hosts python parallel_simulation.py
which gives me error
Open RTE detected a parse error in the hostfile:
/etc/
hosts
It occured on line number 39 on token 12.
--------------------------------------------------------------------------
--------------------------------------------------------------------------
An internal error has occurred in ORTE:
[[57450,0],0] FORCE-TERMINATE AT (null):1 - error base/ras_base_allocate.c(302)
This is something that should be reported to the developers.
This is what I get when I run:
$cat /etc/hosts
# Ansible managed file, do not edit directly
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.
localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.
localdomain6
# Hosts from ansible hosts file
10.1.1.2 titan-install.int.utu.fi titan-install
10.1.1.1 titan-admin.int.utu.fi titan-admin
10.1.1.3 titan-grid.int.utu.fi titan-grid
10.1.100.1 ti1.int.utu.fi ti1
10.2.100.1 ti1-ib.int.utu.fi ti1-ib
10.1.100.2 ti2.int.utu.fi ti2
I would be very grateful if someone could suggest a solution. I am very new to
this and I am not sure how to solve the problem.
