 Post subject: How many cpus and memory when running on supercomputer?
PostPosted: Thu Jul 30, 2020 11:15 pm 
If I want to run a very expensive Singular program on supercomputer, for example primdecSY, then what should I need to consider?

For example, should I ask for 1 task with many cpus (say 20)?

Any help is appreciated.

Currently Singular uses only one cpu with the exception of the routines based on modular.lib,
or parallel.lib for example modStd https://www.singular.uni-kl.de/Manual/4-1-3/sing_1298.htm,
moddiq.lib https://www.singular.uni-kl.de/Manual/4-1-3/sing_1292.htm, and some more.

The number of cpus parallel.lib can use can be set by the command line option
Code:
--cpus=...

see https://www.singular.uni-kl.de/Manual/4-1-3/sing_19.htm
