Hi Sean,
I installed the latest kernel:2.6.17.11 and the latest ib stack: rev 9240
When I compile programs with rdmacm library, I get the error: (though the
program runs fine...)
/usr/bin/ld: warning: libibverbs.so.1, needed by

Hi,
We were wondering if a similar patch is applied to the iWARP side. This
functionality is very useful,
Thanks,

Hi,
With the latest rping code (Revision: 8055) I am still able to see this

I have installed the latest infiniband stack with 2.6.16.20 kernel.

I am planning to use RDMA CM for multicast functionality. It would be
great if you can point me to a simple multicast test program using
RDMA CM?

Hi Sean,
I have a few basic questions:
1. Does the API which waits for join to complete
ensure that the multicast forwarding tables in the switches have been
updated. This is one of the main problems that we had studied:

I was trying to install the latest gen2 with 2.6.16 kernel

Hi,
I was able to create multicast groups after Hal's fix. But, when I do join
subsequently from the same program I am getting a port_alloc error:

I am trying to run a program which creates multicast groups. I am using

Hi,
We have installed the latest openib stack (Rev:2861) on the X86_64
platform. While running the pingpong tests I am encountering the
following error:

I am not sure why this happening ?

Hi,
I am getting an error while destroying the CQ. I am not able to figure out
the reason why I am getting this error. I printed out the error code and
it is 16. Is there anyway by which I can capture the error message and not
just the code ?
Thanks,
Amith
