[CIG-SEISMO] SPECFEM3D_GLOBE - Memory issues when compiling the code

[Dimitri Komatitsch]

Hi,

This all depends on how many processor cores you use for the 
calculations (NPROC_XI and NPROC_ETA). The size of each mesh slice (and 
thus total memory size per processor core) depends on that.

Best regards,
Dimitri.
