Hi today I tried a different rankfile and got once more a problem. :-((

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 sunpc1 rankfiles 109 mpiexec -report-bindings -rf rf_6 hostname [sunpc1:09779] MCW rank 0 bound to socket 0[core 0-1] socket 1[core 0-1]: [B B][B B] (slot list 0:0-1,1:0-1) sunpc1 rankfiles 110 mpiexec -report-bindings -rf rf_7 hostname [sunpc1:09782] MCW rank 0 bound to socket 0[core 0-1] socket 1[core 0-1]: [B B][B B] (slot list 0:0-1,1:0-1) sunpc1 rankfiles 111 mpiexec -report-bindings -rf rf_8 hostname -------------------------------------------------------------------------- The rankfile that was used claimed that a host was either not allocated or oversubscribed its slots.
