Error running Telemac v7p1r1 in parallel on Opensuse Linux with mpich3 8 years 5 months ago #22175

gourish

Hello,

I am running a Telemac 2d example case "wind". I am able to run the case in serial mode.
However when I run the case in parallel using the following command.

python /home/gourish/TELEMAC/v7p1r1/scripts/python27/runcode.py telemac2d -f /home/gourish/TELEMAC/v7p1r1/configs/systel.cis-opensuse.cfg -c susgfopenmpi -s t2d_wind_parallel.cas

I get an error as follows

Is there any extra parameter which I need to pass to the command. Or is there any change required in
the config file.

I am able to run the v6p3 examples in parallel with the default parallel configuration on my Linux Opensuse Leap 43.1 machine, with 8 processor.
(Which is without Mumps solver, for version 6p3 Telemac)

Thanks,
Gourish

Error running Telemac v7p1r1 in parallel on Opensuse Linux with mpich3 8 years 5 months ago #22178

gourish	Hi, The solution was to remove the line --default-hostfile none in the config file. It makes the simulation run, on the stand alone system. Gourish
