[CPMD-list] Memory Allocation Problem

[Alex]

Dear Peng,
P4_GLOBMEMSIZE specifies amount of shared memory. Its default
value too small for CPMD calculation.
This variable most prpbably depend on amount of memory in
your cluster. Just put:

export P4_GLOBMEMSIZE=size_of_shared_memory_in_bytes

in your .bashrc file.
However, I succeed to run calculations only with value around
90mb on our P-III Liinux cluster.

Sincerely,
Olexandr Isayev
