I created a public branch to make available the patch which gets OPMI
uDAPL to kinda work on iWARP. The branch can be found at:
http://svn.open-mpi.org/svn/ompi/tmp-public/iwarp-ompi-v1.2/
The branch contains an updated version of the patch Steve Wise sent out
some time ago. Below is the patch (
While working on OMPI udapl btl, I have noticed some "interesting"
behavior. OFA udapl wants the evd queues to be a power of 2 and
then will subtract 1 for book keeping (ie, so that internal head and
tail pointers never touch except when the ring is empty). OFA udapl
will report the queue length

There is a double call to ompi_btl_openib_connect_base_open in
mca_btl_openib_mca_setup_qps(). It looks like someone just forgot to
clean-up the previous call when they added the check for the return
code.
I ran a quick IMB test over IB to verify everything is still working.

Ok, glad I got this conversation started :)
So, we need a slight redesign to determine the cm method (unless forced
via commandline arg). This can be determined by calling all the
individual open routines, and having them return a priority based on
their ability to function. For example, the xoo

The new cpc selection framework is now in place. The patch below allows
for dynamic selection of cpc methods based on what is available. It
also allows for inclusion/exclusions of methods. It even futher allows
for modifying the priorities of certain cpc methods to better determine
the optimal c

A quick sanity check.
When setting the cq depth in the openib btl, it checks the calculated
depth against the maxmium cq depth allowed and sets the minimum of those
two. However, I think it is checking the wrong variable. If I
understand correctly, ib_dev_attr.max_cq represents the maximum numbe

Did some setting change that perhaps I did not modify?

I'll double check and do a completely fresh svn pull and install and see where
that gets me.

I am seeing some unusual behavior during the shutdown phase of ompi at the end
of my testcase. While running a IMB pingpong test over the rdmacm on openib, I
get cq flush errors on my iWARP adapters.
This error is happening because the remote node is still polling the endpoint
while the other

It requires a unique IP address for every hca/port in use by rdmacm.

Silly question, but I thought openib ONLY worked in Linux. If this is not the
case, then this whole chunk of code will have to be redesigned (if it can
even be done at all)

I know this is slightly premature, but if someone could update the link
below to reflect that iWARP is now supported in OMPI it would be much
appreciated.
