Hello,
The 1.6 release of openmpi fails badly on ia64, see Bug #720419. As no
solution appears to be forthcoming, maybe the best would be to remove
ia64 from openmpi's arch list and switch to mpich2 as default
implementation for mpi-default-{bin,dev}?
I built aces3 on merulo.debian.org with mpich2, and did not encounter
any problem, are there known issues with mpich2 on ia64?
Michael
