Hi Seb,
memoryByCore/Node would clash with the memory option available on the other
environments for any type of jobs (not the openmole memory).
https://next.openmole.org/Documentation_Language_Environments_Clusters.html
Problem is at the moment, as Romain was saying, we can't specify the memory or
number of cores requirements on all the EGI VOs through Dirac.
When this is possible, there will normally be a memory and coreByNodes options
on the EGIEnvironment as well.
Cheers
J.
