Description Gordon Sim 2008-07-01 04:00:50 EDT
Want to avoid having the rdma libs as a dependency for all installations.
Important to allow both tcp and rdma to be used from the same client.
Comment 1 Frantisek Reznicek 2008-10-31 12:04:44 EDT
No test info. How to verify that ifb module exists? Putting NEEDINFO FLAG.
Comment 2 Gordon Sim 2008-11-05 12:44:40 EST
You can run the usual c++ client tests over IB by specifying the protocol. E.g.

perftest -P rdma --count 1000

That assumes you are testing on a box with IB configured (e.g. many of the mrg boxes).

We don't have a test yet that will test simulataneous connections over different protocols in the same client process. That could be written by copying e.g. client test and adding in an extra connection where the protocol on the ConnectionSettings is set to rdma.
Comment 3 Andrew Stitcher 2008-11-05 16:05:54 EST
If you want to check that rdma is a built as a loadable module then run qpidd thus:

qpidd -logging-enable info+

If rdma is a loadable module you will see a line like:

2008-nov-05 16:03:51 info Loaded Module: /usr/lib64/qpid/daemon/rdma.so

Then you can test that rdma actually works using gordons test.

The simplest way to test simultaneous tcp/rdma access to broker is to run perftest over rdma whilst connecting using qpid-tool which can only use tcp.
Comment 5 David Sommerseth 2008-12-08 15:19:39 EST
Found these modules being loaded on startup:
/usr/lib64/qpid/client/rdmaconnector.so
/usr/lib64/qpid/daemon/rdma.so

perftest -P rdma worked as well.

Started qpidd with --no-module-dir and tried perftest -P rdma, and it failed.
