Dear @wgronner, Thank you for your interest in Open Composer.
Yes, Open Composer generates purely shell scripts. However, since the #PBS directive is processed by the job scheduler before the shell is executed, you cannot write variables in the #PBS directive (this is a restriction of the job scheduler). You can probably achieve what you want by writing the form.yml like this: Thanks |

Hello mnakao, thank you for your quick response. #PBS -l select=#{ncores}/#{queue}:ncpus=#{ncores}:mpiprocs=#{ncores} The following line is now generated. However, I was of the opinion that the following result would be generated The calculation does not seem to be performed in the script section. Have I overlooked something? Thanks |

I understand what you want to do. You want to automatically calculate the number of nodes specified in the select directive. Unfortunately, Open Composer cannot perform calculations on variables assigned to it. The user must manually calculate the number of nodes and the number of cores per node to be utilized as follows: From your first post, it seems that the number of MPI processes is determined by the queue, so I set it in the Currently, Open Composer can only do this, but I thought it would be useful to be able to perform simple calculations like you suggested.

Hello everyone,
first of all, respect for this great software. This is exactly what OpenOndeman was missing.
It's amazing how much you can customize your workflow to create a job script.
But now to my question.
Is it possible to use calculations or conditional statements ( if-then-else ) within the script section?
For example:
if #queue = “small” then
corepernode=20
sel=ncores/corepernode
else
corepernode=40
sel=ncores/corepernode
endif
#PBS -l select=@sel:ncpus=ncores:mpiprocs=@corepernode
#PBS -l select=@sel:ncpus=ncores:mpiprocs=@corepernode
I hope I have been able to explain the situation to some extent.
Thank you for any assistance
