Hi Jack,
Thanks for the tip. (*Embarassed*)
I think a Kernel upgrade since might have broken the source RPM. Is
there any way for me to fix this? (I have an identical hardware server

This allows to build under FC11. Otherwise, building shared libraries using
libreplace results in the following error:
.../ibutils/ibdm/replace/libreplace.a(regex.o): relocation R_X86_64_32S against
`a local symbol' can not be used when making a shared object;

Hi,
here are some fixes I had to apply in order to be able to build under FC11
due to some changes in the toolchain.
Sebastien.

We have a new cluster with QDR infiniband.

1. call select() on completion channel with zero
timeout and return 0.
2. call ibv_poll_cq() directly and return 0.
Question:
Which way has lower overhead ?
ibv_poll_cq
We know select() has to switch to kernel mode, does ibv_poll_cq()
switch to kernel mode
But I just check the source code, ibv_poll_cq() is actually ibv_cmd_poll_cq(),
and ibv_cmd_poll_cq() calls write() system call on the IB device.
Doesn't this write() system call switch to kernel mode and possiblely casuse
a context switch ?
See verbs.h:
static inline int ibv_poll_cq(struct
Sean:
I understand that ops.poll_cq is actually ibv_cmd_poll_cq(), right ?
Do you mean during ibv_poll_cq() call, there is no system call involved
?

No, not for most devices. Look at libmthca, etc to see what the poll_cq
method is set to.

Right, for most devices poll_cq can be done
Since 2.6.31-rc8 has been out more than a week already, it's probably
a good time to talk about 2.6.32 merge plans. All the pending things
that I'm aware of are listed below.
Boilerplate:
If something isn't already in my tree and it isn't listed below, I
probably missed it or dropped it
I did not understand the relation between ops.poll_cq() and ibv_cmd_poll_cq()
correctly.
It is clear now.
Thank you.
