[openib-general] udapl:al:query_req_cb() !ERROR!: query failed:

Mon Apr 26 05:33:18 PDT 2004

I didn't see a reply to this, but I can offer a couple of insights.

The only significant error is:

DAPL needs to know what the IP address is of the initiating side. To determine what this is, current DAPL implementations get it from the HCA driver. But older implementations, such as the OpenIB stack you are using, obtain it by using the hostname and adding "-ib0" to the end of it, then invoking getaddrinfo() to get the IP address.

You are running on a machine named "score2", so this simple algorithm will create the local name "score2-ib0", which is what you see in the error string above.

It appears that you don't have an entry for 'score2-ib0' in you DNS system or in your /etc/hosts file. Add an entry with the correct IP address and things will probably work. Or you'll get to the next bug ;-).

I don't know what this is all about, but things keep going so perhaps you can ignore it for now?

This error is because the local IP address was not determined, as I outlined above.

... and finally, this set of errors is because the DAPL implementation is out of date, there are still some bugs with cleanup/close.
