Hi,
I installed openmpi-1.9a1r29097 on "openSuSE Linux 12.1", "Solaris 10
x86_64", and "Solaris 10 sparc" with "Sun C 5.12" in 64-bit mode.
Unfortunately I still have a problem with rankfiles. I reported the
problems already in May. I show the problems with Linux, although I
have the same problems on all Solaris machines as well.
linpc1 rankfiles 99 cat rf_linpc1
# mpiexec -report-bindings -rf rf_linpc1 hostname
rank 0=linpc1 slot=0:0-1,1:0-1
linpc1 rankfiles 100 mpiexec -report-bindings -rf rf_linpc1 hostname
[linpc1:23413] MCW rank 0 bound to socket 0[core 0[hwt 0]],
socket 0[core 1[hwt 0]]: [B/B][./.]
linpc1
linpc1 rankfiles 101 cat rf_ex_linpc
# mpiexec -report-bindings -rf rf_ex_linpc hostname
rank 0=linpc0 slot=0:0-1,1:0-1
rank 1=linpc1 slot=0:0-1
rank 2=linpc1 slot=1:0
rank 3=linpc1 slot=1:1
linpc1 rankfiles 102 mpiexec -report-bindings -rf rf_ex_linpc hostname
--------------------------------------------------------------------------
The rankfile that was used claimed that a host was either not
allocated or oversubscribed its slots. Please review your rank-slot
assignments and your host allocation to ensure a proper match. Also,
some systems may require using full hostnames, such as
"host1.example.com" (instead of just plain "host1").
Host: linpc0

I don't have these problems with openmpi-1.6.5a1r28554.

I would be grateful, if somebody can fix the problem. Thank you
very much for any help in advance.
Kind regards
Siegmar
