Hello Libor,
I've tried your patch, but unfortunately it made no difference to the -32/-104 errors I get. I have observed the following features, which may help you diagnose my problem:
Platform: 64 bit
OS: RHEL 4
Kernel: 2.6.11.6
OpenIB gen2: 2225
SM: IO5000 switch
Steve,
I'm not seeing this issue on my x86_64 systems. Is there anything
in the syslog on either system? If you build SDP with debug, there
will be messages in the log, any errors? Which HCA are you using, and
which firmware? Also, can you send the exact command line?

Hi Libor,
Actually your patch did make a difference (thanks). After playing around with ttcp.aio a bit more I now find that long runs now work fine if the message size is larger than the zero copy threshold. I'll get back to you tomorrow about the details of my setup. I did turn debugging on, but did not see any different messages when the -32/-104 error occurred, now for message sizes smaller than the zero threshold.
Cheers,
Steve. _______________________________________________ openib-general mailing list openib-general@openib.org http://openib.org/mailman/listinfo/openib-general
