patch from dledford

Comment 2 Clark Williams 2009-11-13 21:30:21 UTC
patch queued for -138 build

Comment 4 David Sommerseth 2009-11-19 19:50:36 UTC
Verified that the update-OFED-to-v1.4.1.patch was included in the 2.6.24.7-139 source RPM.

CVS: update-OFED-to-v1.4.1.patch
mrg-rt-v1.git: 653b0a56d973ff488d6197fe8fb44940c4ab0c94

Smoke tested the driver on mrg42 and mrg43 with a flood ping:
[root@mrg43 ~]# ping -s 65507 -f 192.168.2.42 -c 100000
PING 192.168.2.42 (192.168.2.42) 65507(65535) bytes of data.

--- 192.168.2.42 ping statistics ---
100000 packets transmitted, 100000 received, 0% packet loss, time 50000ms
rtt min/avg/max/mdev = 0.339/0.388/0.481/0.032 ms, ipg/ewma 0.500/0.383 ms
[root@mrg43 ~]# 

This generated about 6GB of data.  192.168.2.42 is the ib0 device on mrg42 and 192.168.2.43 is ib0 on mrg43.

Further, installed MRG Messaging and ran latency test ...

[root@mrg43 ~]# latencytest -b 192.168.2.42 --tcp-nodelay --rate 40000 --size 512
Latency(ms): min=0.17708, max=2.02211, avg=0.402712
Latency(ms): min=0.180148, max=1.56898, avg=0.374544
Latency(ms): min=0.179082, max=1.37873, avg=0.36802

and similar results, without much variation, came until it was stopped about 15 minutes later, which had generated another 16GB of data traffic on the ib0 devices.
