style='font-size:10.0pt'>Hi<br>
<br>
Following is our question.<br>
<br>
Thanks<br>
<br>
Suo<br>
<br>
----------------------------------------------------------------------------<br>
--------------------------------------------<br>
<br>
<br>
<br>
We already wrote a IOCP and WinSocket based communication program. The<br>
testing upon Infiniband indicated that this program still go over the<br>
IPOverIP and has the overhead of Windows IP stack.<br>
<br>
<br>
<br>
We saw this PPT and want to know how our WinSocket based program can fully<br>
utilize the capabilities of Inifniband RDMA and how to write code over WSD<br>
to avoid the overhead of Windows IP stack.<br>
<br>
<br>
<br>
We just need a sample code like the source code of tool<br>
SDPConnect.exe(within the Mallanox driver tools folder) etc. It showed great<br>
performance we can’t achieved by our WinSocket code.<br>
<br>
<br>
<br>
We’ve got some progress improvement:<br>
<br>
1. By searching the source code in OpenFabric, it turns
out that these<br>
open source include some tools’ source code, like this c file attached;<br>
<br>
2. There was some code founded in such tool’s source code
like:<br>
<br>
while (ccnt < user_param->iters || rcnt < user_param->iters ) {<br>
<br>
while (scnt < user_param->iters
&& (scnt - ccnt) <<br>
user_param->tx_depth / 2) {<br>
<br>
ib_send_wr_t *bad_wr;<br>
<br>
tposted[scnt] = get_cycles();<br>
<br>
ib_status
= ib_post_send(qp, &ctx->wr, &bad_wr);<br>
<br>
if
(ib_status != IB_SUCCESS) {<br>
<br>
fprintf(stderr, "Couldn't post send: scnt=%d<br>
ib_status %d\n",<br>
<br>
scnt,ib_status);<br>
<br>
return 1;<br>
<br>
}<br>
<br>
++scnt;<br>
<br>
PERF_DEBUG("scnt
= %d \n",scnt);<br>
<br>
}<br>
<br>
<br>
<br>
But no document just have to guess from the source code for what “qp”,<br>
“ctx” means and how to use them. These “ib_” initiated APIs were<br>
absolutely NOT WinSocket APIs. What we asked for is SDK or documents for how<br>
to using such API and which Header files we should include and which lib<br>
have to be linked. A sample project will be OK if no such document exists.<br>
<br>
<br>
<br>
<br>
</span>Thanks <o:p></o:p></p>

<o:p></o:p></p>
<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>When
I use WSD in my project, I found the sample code is very difficult to use.
Because the sample code is very simple.<o:p></o:p></p>
<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>I
want to know where can I get a detail sample code for WSD. Because my
application must use zero copy to get good performance.<o:p></o:p></p>
