long Engines::ResourceParameters::mem_mb

required memory size

This parameter must be specified explicitly, because it is not provided by the resource definition.

The parameter specifies the maximum memory value that could be allocated for executing the job. This takes into account not only the data that could be loaded by the batch process but also the linked dynamic library. A possible problem, for exemple in the case where you use the ssh emulation of a batch system, is to get an error message as below when libBatch tries to run the ssh command:

/usr/bin/ssh: error while loading shared libraries: libcrypto.so.0.9.8: failed
to map segment from shared object: Cannot allocate memory

In this exemple, the mem_mb was set to 1MB, value that is not sufficient to load the dynamic libraries linked to the ssh executable (libcrypto.so in the error message). So, even in the case of a simple test shell script, you should set this value at least to a standard threshold as 500MB.

string Engines::ResourceParameters::name

resource name - manual selection

If a name is provided, the ressource will be imposed. If the name is an empty string, the ressource will be chosen to match the other parameters.

long Engines::ResourceParameters::nb_node

required number of nodes

long Engines::ResourceParameters::nb_proc

required number of processors

This parameter must be specified explicitly, because it is not provided by the resource definition.
