[openib-general] MVAPICH viadev_post_recv issue

[Ira Weiny]

With the new 1.0 branch of stuff.  (Pulled from svn about a week ago.)  I have been getting the following error from mvapich.


[0] Abort: Error posting recv 22 (0x735f88 ?= 0x735804)
 at line 176 in file viapriv.c
[1] Abort: Error posting recv 22 (0x735f88 ?= 0x735804)
 at line 176 in file viapriv.c

The number there is the return code from ibv_post_recv.  I don't understand where that value is comming from.  ibv_rc_pingpong is working just fine.

What am I doing wrong?
Ira


I changed the print this way:
