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.

Sorry, looks like I busted you. Please pull the latest bits and verify my

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)

It requires a unique IP address for every hca/port in use by rdmacm.
I see the bug in rdmacm (since I don't believe

This error is happening because the remote node is still polling the endpoint

I'll double check and do a completely fresh svn pull and install and see where

Did some setting change that perhaps I did not modify?

I am noticing that ssh seems to be broken on trunk (and my cpc branch, as it

After discussing this issue with Jeff via private e-mails. I would like
to open the issue to the group for futher discussion.
Issue (as described by Steve Wise):
Currently OMPI uses qp 0 for all credit updates (by design). This breaks
when running over the chelsio rnic due to a race condition be
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

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

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
Currently, alternate CMs cannot be called because

functions can easily be added. New Open

Sorry, I was just trying to err on the side of caution and openness. Do
you have a rule of thumb for what should be sent on the list versus
simply committed?

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.

While working on OMPI udapl btl, I have noticed some "interesting"
