Hi Rene,It should be $PVFS2/test/io/bmi/pingpong.c. I have attached copy if you do not have it. You should be able to drop it in that directory and build it.
usage: pingpong -h HOST_URI -s|-c [-u]
where:
HOST_URI is tcp://host:port, mx://host:board:endpoint, etc
-s is server and -c is client
-u will use unexpected messages (pass to client only)
On the server with hostname foo, run:
$ ./pingpong -h tcp://foo:5000 -s
and on the client, run:
$ ./pingpong -h tcp://foo:5000 -c
If you pass -u, it will test unexpected messages only.

Hi Scott,I have pvfs compiled and configured to use both bmi_ib and bmi_tcp (willprobaly 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?
