The IP addresses and ports seem to be correctly setup, so that's not the problem. I created my own amazon instances to see what the problem is. It looks like the instances are not able to communicate even though there's no explicit firewall enabled that is shown inside the Linux instance. I did some digging and found the "Security group" settings and found that the inbound rules only allowed ssh. I changed it to "All traffic" and now I can run my jobs fine. % ./install/bin/mpiexec -hosts ec2-52-36-15-57.us-west-2.compute.amazonaws.com,ec2-5 2-37-222-189.us-west-2.compute.amazonaws.com -n 4 ./examples/cpi Process 3 of 4 is on ip-172-31-28-127 Process 2 of 4 is on ip-172-31-21-12 Process 1 of 4 is on ip-172-31-28-127 Process 0 of 4 is on ip-172-31-21-12 pi is approximately 3.1415926544231243, Error is 0.0000000008333312 wall clock time = 0.010181 Can you try that? -- Pavan _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
