Subject: strong ordering for data registered memory
Date: Tue, 10 Nov 2009 15:19:26 -0500 [thread overview]
Message-ID: <4AF9CACE.8070700@Sun.COM> (raw)
Some time ago there was an email sent to this group with the subject
"weak ordering for data registered memory". I don't recall any action
resulting from this thread. So, I have a question. If a bit were
defined to specify "strong ordering", perhaps as a "access" flag (see
ibv_access_flags) and used with ibv_reg_mr(), would that be sufficient
for (1) client applications that need a HW "guarantee" of writing the
last byte of an RDMA last and (2) platform implementations that need to
deliver that feature?
