No, but this is the same job that I already successfully ran with an oldest version (4.4.4) I would like to update.
I sent this job as a test because I now this problem might happen AIX power 4 computers, but I dont know how to solve it.

Hi,
It may happens on IBM systems that the maximal amount of memory
available for a single job is just limited to a small (to very small)
part of the available memory. Have you checked if you are able to
allocate a 1GB array (with a small C program for instance) ?

Dear Abinit users,

I know my problem is known on IBM AIX Power 4 computer, however I looked at the FAQ and did not found a satisfactory answer.

I just compiled the 5.2.4 abinit version" on an IBM AIX Power 4 computer.
I try to run it (abinis) and get the error message below:



===================================================================== ===========
P This job should need less than 1339.190 Mbytes of memory.
Rough estimation (10% accuracy) of disk space for files :

===================================================================== ===========

Biggest array : cg(disk), with 1056.6790 MBytes.

memana : ERROR -

It is not worth to continue

or increase limit on maximal array size.

leave_new : decision taken to exit ...

I tried the option -bmxdata:2048000000 as described in the FAQ but whith no success. However, the makefile has largely been modify since the answer of the FAQ has been written. May be did I include it in a wrong place.

Does somebody could help me please ?

Thank tou very much
