Hi,<br><br>I read a paper on "Zero Copy Sockets Direct Protocol over InfiniBand". I
had a few questions, if anybody could answer I will be thankful.<br><br>1. SDP BCopy approach can be used without
the change of the code via the use of AF_INET_SDP parameter when
calling socket() system call. But how can I implement SDP ZCopy
approach if I want to implement ZCopy_Read and ZCopy_Write methods?<br>
<br>2. Is there any documentation regarding how to implement SDP ZCopy?
Any Hello World sort of example code that I can use to learn how to
work with this?<br><br>3. SDP BCopy is better for smaller messages, but how small? Is 64K a good threshold to change from BCopy to ZCopy at 128K?<br clear="all">
<br>Looking forward for your reply.<br><br>Best Regards,<br>-- <br>Syed Zafar ul Hussan Gilani | BIT-7<br>Research Student | CHPSC<br>MSP 2008-09<br>NUST SEECS | <a href="http://hpc.niit.edu.pk/~zafar">http://hpc.niit.edu.pk/~zafar</a><br>
