Rankfile rf_6 is the same as last time. I have added one more
line in rf_7 and I switched the sequence of the hosts in rf_8.
Everything is still fine with rf_6. I don't get any output for
rank 1 with rf_7 and I get an error for rf_8. Both machines
use the same hardware.
sunpc1 rankfiles 106 cat rf_6
# mpiexec -report-bindings -rf rf_6 hostname
rank 0=sunpc1 slot=0:0-1,1:0-1
sunpc1 rankfiles 107 cat rf_7
# mpiexec -report-bindings -rf rf_7 hostname
rank 0=sunpc1 slot=0:0-1,1:0-1
rank 1=sunpc0 slot=0:0-1
sunpc1 rankfiles 108 cat rf_8
# mpiexec -report-bindings -rf rf_8 hostname
rank 0=sunpc0 slot=0:0-1,1:0-1
rank 1=sunpc1 slot=0:0-1

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: sunpc0
--------------------------------------------------------------------------
I get the following output, if I use sunpc0 as local host.
sunpc0 rankfiles 102 mpiexec -report-bindings -rf rf_6 hostname
--------------------------------------------------------------------------
All nodes which are allocated for this job are already filled.
--------------------------------------------------------------------------
sunpc0 rankfiles 103 mpiexec -report-bindings -rf rf_7 hostname

I get the following output, if I use tyr as local host.
tyr rankfiles 218 mpiexec -report-bindings -rf rf_6 hostname

--------------------------------------------------------------------------
tyr rankfiles 220 mpiexec -report-bindings -rf rf_8 hostname
--------------------------------------------------------------------------

--------------------------------------------------------------------------
Do you have any ideas why this happens? Thank you very much for
any help in advance.
Kind regards
