<P><FONT size=2>Hello all,<BR> I'm working on DAT v2 extensions which
include an Atomic<BR>Compare-n-swap operation.<BR>The comp-n-swap operation
generates an async QP error callback with<BR>IB_AE_WR_REQ_ERR?<BR>The
IB_AE_WR_REQ_ERR code is defined as 'an Opcode violation @
the<BR>responder'?<BR><BR>Any clues as to what might generate an
IB_AE_WR_REQ_ERR or what an<BR>opcode violation @ responder
implies?<BR><BR>Anyone have an IBAL based compare-n-swap test program they would
like
to<BR>share?<BR><BR>Thanks,<BR><BR>Stan.<BR>_______________________________________________<BR>ofw
