WRONG. You *did* answer -- somehow my mail client ate it (I see the reply in the web archives, but not in my local mail client -- #$@!$@!#$!!!!).

My bad... :-(

Could you add some of your explanations as comments in the code? The rationale here is that if I had those questions while reading your patch, someone else (including me, months from now) will likely have the same questions while reading the code.

Another minor quibble in a help message:

+[SRQ doesn't found]
+The srq doesn't found.
+Below is some information about the host that raised the error:
+ Local host: %s
+ Local device: %s

It's not correct grammar and is fairly unhelpful to the user -- please change to:

[SRQ not found]
Open MPI tried to access a shared receive queue (SRQ) that was not found. This should not happen, and is a fatal error. Your MPI job will now abort.

    Local host: %s
    Local device: %s


+ - When the number of not used receive buffers will decreased to 8
+ the IBV_EVENT_SRQ_LIMIT_REACHED event will be signaled and the number
+ of receive buffers that we can pre-post will be increased.

I don't think users know what IBV_EVENT_... is. Perhaps it should read:

+ - When the number of unused shared receive buffers reaches 8, more
+ buffers will be posted.

(how many more buffers will be posted, BTW?)
