[bgl-discuss] memory error

[Yaakoub El Khamra <yye00@xxxxxxxxxxx>]

Greetings
We are running Cactus optimization/benchmark runs with various 
compilation flags on bgl with a constant local processor problem size 
(80x80x80).  At the moment we are experimenting with '-qmaxmem=64000 -O5 
-qtune=440  -qarch=440d' compilation flags. In runs on 1,2,4,8,12 and 16 
processors we encounter no problems, however when we move to 24 
processors (all in 'co' mode) the code crashes. The job's .error file 
contains the following message:
1525-108 Error encountered while attempting to allocate a data object.  
The program will stop.
Since no core file is produced tracking this error is problematic. Can 
anybody provide some insight on how this error occurs or any suggestions 
on how to track it?

Thanks in advance


Yaakoub
