Hi, Yongting,

Have you solved the problem then? I encountered almost the same problem
as you when I used my supercell models:

Biggest array : cg(disk), with     69.3111 MBytes.
-P-0000  leave_test : synchronization done...
 memana : allocated an array of     69.311 Mbytes, for testing purposes.
-P-0000
-P-0000  memana : ERROR -
-P-0000   Test failed to allocate     357.414 Mbytes
-P-0000   It is not worth to continue
-P-0000   Action : modify input variable to fit the available memory.
-P-0000   or increase limit on available memory.
-P-0000
-P-0000  leave_new : decision taken to exit ...
-P-0000  leave_new : synchronization done...
-P-0000  leave_new : exiting...

The problem can be solved by set mkmem=0 when my system contains 8
atoms, but didn't work for the supercell with more atoms. I also wonder
which variable is relative to this kind of problem. Hope anyone here can
give me some suggestions. Thanks in advance.

Best regards.

Chun Li

Dear all abinitors:
If I want to increase limit on maximal array size, I should modify which
varible.
And wish urgently to get help, thank you.
