I am running SDP on rev 3882 on ia64 (modified RHEL4 - 2.6.12 kernel).
I do not run NetPIPE but TTCP with options "-l 1048576 -b 1048576" which I
think means 1M.
I just tried a run with "-l 2097152 -b 2097152" which then would mean 2M and
it seems to run okay:
ttcp-t: buflen=2097152, nbuf=45000, align=16384/0, port=5001,
sockbufsize=2097152 tcp -> 192.168.0.100
ttcp-t: 94371840000 bytes in 148.11 real seconds = 607.65 MB/sec +++
ttcp-t: 45000 I/O calls, msec/call = 3.37, calls/sec = 303.82
ttcp-t: user: 41016 sys: 36393573 total: 36434589 real: 148112374
But maybe, TTCP does not run message size > 1M even with these options
set?...

Has anyone tried using SDP on Itanium ?
Yes - but it's been 5-6 weeks since I have tried it (SVN r3547).
I was trying to run a NetPIPE over SDP (svn Rev 3882).
It seems to run fine for small transfers, but
the applications hangs when it gets to > 1 Megabyte
transfers.
I haven't tested message sizes > 128KB.
I'll include 256/512/1024/2048 KB message sizes in the next round.
And I still owe Michael some investigation results from the
last round were perf dropped off to near zero for medium
sized messages.
