Hi libfabric folks,

In implementing the FI_DISCARD feature for the gni provider,
we are trying to decide whether a call to fi_trecvmsg with flags
set to FI_CLAIM | FI_DISCARD (following a previously issued
fi_trecvmsg with FI_PEEK | FI_CLAIM)  should generate a

It appears that the the sockets and psm(at least version 2)
do generate a CQ event for FI_DISCARD option,  but given there aren't
any fabtests that test FI_DISCARD yet, we thought it might
be good to double check on the mail list.

Thanks for any info,
