Hi Scott,
I have pvfs compiled and configured to use both bmi_ib and bmi_tcp (will
probaly try MX later):
BMIModules bmi_ib,bmi_tcp
Alias hpcxe001a ib://hpcxe001:3335,tcp://hpcxe001:3334
Alias hpcxe001b ib://hpcxe001:3337,tcp://hpcxe001:3336
Alias hpcxe003a ib://hpcxe003:3335,tcp://hpcxe003:3334
Alias hpcxe003b ib://hpcxe003:3337,tcp://hpcxe003:3336
I guess maybe its trying to use tcp over IB or something. I will rip
out the IB stuff so there is no chance of that and try again.
Just looked in cvs and did not see the bmi_pingpong test do you mind
sending me a copy?
Thanks
Rene
