Problems running on a PBS cluster

[Mikael Chala]

Hi,

I am trying to run Delphes3 on a PBS cluster and I get the following error:

"MG5_aMC_v2_1_1/Delphes/DelphesSTDHEP: error while loading shared libraries: libGraf3d.so.5.34: cannot open shared object file: No such file or directory"

"MG5_aMC_v2_1_1/Delphes/root2lhco: error while loading shared libraries: libGraf3d.so.5.34: cannot open shared object file: No such file or directory"

It seems to occur only when I call several instances of Delphes at the same time. However, I do not get such an error when running on my own computer.

Any suggestion?

Thank you so much.

All the best,

Mikael Chala.

Hi Mikael,

I'd say that your PBS job should configure the ROOT related environment variables on the remote machine where it's running.

Normally, it can be done in a shell script:

#! /bin/sh
# setup ROOT
# run Delphes
/full/path/to/Delphes...

Let's call this script 'delphes.sh'. When you can submit a PBS job:

qsub delphes.sh

Regards,

Pavel
