The ABINIT Users Mailing List ( CLOSED )

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

1)Power5 are one of the test platform at pcpm.
2) With a decent network and a large number of k-point there is no
problem to run abinit in parallel on a large number of nodes (I
personnaly have never used more than 1024 cpu >= 256 nodes)
3) Abinit 5.2 is supposed to compile out of the box fine on such
machine yet, if you came over some problem you might be interested in
reading a recent thread (1-3 weeks) on parallel compilation on IBM
machine.
