Running in Parallel on cluster
Hello,
I'm trying to run a cache on my school cluster. Currently I'm issuing following command: Code:
mpirun --hostfile system/machines -np 6 pimpleFoamScalar -parallel Code:
XXX@top.nbi.dk slots=2 max-slots=2 Code:
[top.nbi.dk:18796] btl: tcp: attempting to connect() to address 130.225.212.8 on port 260 Any help or clues as how to debug the problem would be appreciated! Thank you. |
There is a OpenFoam cluster receipe, in the second page, in this same forum.

This does not solve my problem - The machines share the same network drive and I've decomposed, made the hostfile etc. correctly.

[top.nbi.dk][[19986,1],0][btl_tcp_endpoint.c:638:mca_btl_tcp_endpoint_comple te_connect] connect() to 130.225.212.8 failed: No route to host (113)
This looks like a network problem (misconfiguration?). First of all, check if you can connect from one node of the cluster to any another node; e.g., like this: telnet 130.225.212.8 260; if you get this message "no route to host", check the network configuration. |
