<div>
<p><span style='font-size:10.0pt'>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>
