[ofa-general] should it be possible to run SDP over a T320?

[Rick Jones]

Hi -

I was talking to someone about the numbers I'd gathered for IPoIB with 
OFED 1.2 and a Mellanox HCA, and how the MTU increase from 2044 to 65520 
did some non-trivial things to bulk transfer performance.  This person 
suggested it should be possible to run SDP over a Chelsio T320, which I 
happen to have in my systems at present.  However, my initial simplistic 
attempt was unsuccessful:

[root at hpcpc106 OFED-1.2-20070626-0917]# netperf -t SDP_STREAM -c -C -H 
192.168.2.107 -l 30
SDP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 192.168.2.107 
(192.168.2.107) port 0 AF_INET
netperf: send_sdp_stream: data socket connect failed: Network is unreachable

This is with:

[root at hpcpc106 OFED-1.2-20070626-0917]# ethtool -i eth2
driver: cxgb3
version: 1.0.094
firmware-version: T 4.1.0
bus-info: 0000:08:00.0

and the "native" SDP netperf tests rather than any LD_PRELOADed library.

Am I on a wild goose chase, or should it be possible to do SDP over the 
T320 with OFED 1.2 bits on the system?

thanks,
