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