Dear all,

Have you encountered the similar problems before when using parallel
version of abinit? Could anyone here give me some suggestions? I have
been puzzled by this error for about two weeks. 

I have tried recompiling abinip with different versions (4.3.3, 4.4.2)
on IBM p655 cluster, the abinip was made, but the same error appeared
after I submitted the task with more than 1 node (I tried using only one
cpu, that is, tasks_per_nodes=1, the job can run normally).

I think the problem is relative to the MPI. Is there anyone who has
compiled abinip on IBM cluster successfully? Could you give me your
makefile_macros file for conference? Maybe the problem lies in there.
Thanks a lot.

Any suggestion from you is appreciated.

Best regards.

Chun Li

Subject: [abinit-forum] buffer size error

Dear all,

When I perform calculations on a cluster using parallel version of
abinit, the following error always appeared in the err file:

ATTENTION: 0031-408  2 tasks allocated by LoadLeveler, continuing...
> ERROR: 0032-117 User pack or receive buffer is too small  (4) in 
> MPI_Bcast, task 1
> ERROR: 0031-250  task 1: Terminated
> ERROR: 0031-250  task 0: Terminated

I have searched the error on the web, but have not got proper solutions.
I also tried to set the -io_buffer_size=128M (the limited value), the
error still exists. I am sorry this is not a problem of abinit. But I
think there must be someone who has experiences on this kind of
problems. Could anyone give me some ideas? Thanks a lot.

Best regards.
