It is said in "Zero Copy Sockets Direct Protocol over InfiniBand -
Preliminary Implementation and Performance Analysis" that the FMR
is a Mellanox feature extending the 1.1 InfiniBand specification, and a
similar feature was added later on to the 1.2 InfiniBand specification.
But I have got nothing about the FMR in "InfiniBand™ Architecture
Specification Release 1.2"
(<a href="http://www.infinibandta.org/specs/register/publicspec/">http://www.infinibandta.org/specs/register/publicspec/</a>). <br>
I read the description of FMR related verbs in "Mellanox IB-Verbs API
(VAPI) 1.00, however I am not very clear of the difference
between FMR registering and common registering. Is there a description
of more details?<br>
Any suggestion is appreciated!<br clear="all"><br>-- <br>Ian Jiang<br><a href="mailto:ianjiang.ict@gmail.com">ianjiang.ict@gmail.com</a><br><br>Laboratory of Spatial Information Technology<br>Division of System Architecture
