Hi,
?: Does WinOF suppose to be compatible with (Linux) OFED 1.1?
I ran the ib_send_bw test, and found out that the 2 stacks
aren't compatible, so would someone please shed some lights
on this incompatibility, please?
Here're the test results:
1. Linux as client & server: works.
This includes:
a. One single Linux running as both server & client.
(This is a silly, but sanity test.)
b. Two different Linux running as server & client.
2. Windows as client & server: works.
3. Linux as server. Windows client failed with:
Completion wth error at client:
Failed status 9: wr_id 1 syndrom 0x81
scnt=1000, ccnt=0
(Linux server does report "remote address ..." so there
seems to be some connection.)
4. Windows as server. Linux client failed with:
Completion wth error at client:
Failed status 12: wr_id 1 syndrom 0x81
scnt=300, ccnt=0
(Again, Windows server reports connection from client.)
5. If I specify '-c UC' or '-c UD', then the client reports
that it completed 1000 iterations together with the
calculated peak/average bandwidths. However, both client
and server seem hang, and requiring a Control+C to terminate
the test.
6. *IMPORTANT*: in all cases, the LID of the Windows host is
always shown in reverse-byte order! E.g. Windows vstat
report a Windows port LID is 0x1234, then:
a. Linux reports "remote address: LID 0x3412"
b. Windows reports "local address: LID 0x3412"
c. In case server & client are both Windows,
then both report LIDs in reverse-byte order.
So is it an indication some (Windows?) code didn't do
a host-to-net conversion for LID?
7. I also dual-boot a Windows host as Linux, then
ib_send_bw ran flawlessly. That proves no problem
with hardware, HCA, fabric, cabling, etc., so the
problem is purely software.
8. Versions:
a. Linux: OFED 1.1
b. Windows: 1.0.0.614 downloaded from
http://openib.tc.cornell.edu/downloads/binaries/1.0.0.614/
So I'd appreciate anyone who can shed some lights on this issue.
thanks
ham
