IBV_SEND_INLINE Behavior Differing from Spec

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hey all,

The manpage for ibv_post_send indicates that if you specify the
IBV_SEND_INLINE flag, that you can immediately re-use the buffer after
ibv_post_send() returns. However, I have found that if I modify the
buffer immediately after ibv_post_send(), the changes are rarely
reflected in the presumably already-posted message. I'm using
ConnectX-3 cards and RC connections, if that's relevant. Is this a
known issue, and/or is it possible I'm missing something obvious?

Cheers,
Christopher
