The ABINIT Users Mailing List ( CLOSED )

[Anglade Pierre-Matthieu <anglade@gmail.com>]

Ok I understand now.
This means that mpich is ill configured on the system or that it's
configuration is not compatible with the binary you've downloaded.

In fact, MPI is using its own processes to manage the communications
between yours (abinit). Obviously your program must "send" it's data
to the mpi process which fwd them to other processes on other nodes.
(For this, mpi can use the standard unices Inter Process Communication
services (IPC). There is three kinds of IPC: shared memory segments,
semaphore arrays ans message queues (pipes). you can manage them using
ipcs and ipcrm commands)

However This is truly the standard behavior, it is mandatory end it
isn't so called  shared memory paralelism. So what you have to do is
just to compile abinit along with you mpi facilities. Or to ask your
sysadmin for a reconfiguration of MPI. The error is by no way coming
from abinit itself.
