Hi
How to set rank to specific lid ?
I use MVAPICH 0.9.9
For example I have
host0 ib0 base lid 10, multi lid 11 multi lid 12 ...
host1 ib0 base lid 15, multi lid 16 multi lid 17 ...
host2 ib0 base lid 20, multi lid 21 multi lid 22 ...
LMC = 2
Topology:
switch0
/ \
switch1 ------- switch2
/ \ \
host0 host1 host2
I can to set this routs with using LMC
host1 -> switch2 -> switch1 -> host0
host2 -> switch2 -> switch0 -> switch1 -> host0
How i can set this ratio:
mpi proc 0 rank 0 lid 10
mpi proc 1 rank 1 lid 16
mpi proc 2 rank 2 lid 22
Do anyone know anything about this ?
Thanks in advance.
