<p class="MsoNormal"><span style="font-size:11.0pt">In my previous answer to your second question, I meant that you should run that or a similar benchmark on a real (not simulated) system to get an accurate startup parameter for the system you are simulating.
Eventually you'd want to use something like the loggp model that IIRC we've talked about off-thread, but simplenet is at least a reasonable model to start with.<o:p></o:p></span></p>

<p>Hi John,<o:p></o:p></p>
<p>Thanks for your response.<o:p></o:p></p>
<p><o:p> </o:p></p>
<p>For the first question, the configuration is as follows:<o:p></o:p></p>
<div>
<p class="MsoNormal" style="margin-bottom:12.0pt">LPGROUPS {<br>
## cluster foo<br>
FOO_CLUSTER {<br>
repetitions="12";<br>

}<br>
FOO_FORWARDERS {<br>
repetitions="4";<br>
forwarder="1";<br>
modelnet_simplenet@foo="1";<br>
}<br>
## cluster bar<br>
BAR_CLUSTER {<br>
repetitions="12";<br>
node="1";<br>
modelnet_simplenet@bar="1";<br>
}<br>
BAR_FORWARDERS {<br>
repetitions="4";<br>
forwarder="1";<br>
modelnet_simplenet@bar="1";<br>
}<br>
}<br>
<br>
PARAMS {<br>
## ROSS parameters<br>
message_size="352";<br>
<br>
## global modelnet parameters <br>
modelnet_order=("simplenet");<br>
<br>
## foo cluster network parameters <br>
packet_size@foo="8192";<br>
modelnet_scheduler@foo="fcfs";<br>
net_startup_ns@foo="1.5";<br>
net_bw_mbps@foo="10000";<br>
<br>
## bar cluster network parameters<br>
packet_size@bar="2048";<br>
modelnet_scheduler@bar="round-robin";<br>
net_startup_ns@bar="3.0";<br>
net_bw_mbps@bar="15000";<br>
<br>
## forwarding network parameters<br>
packet_size="4096";<br>
modelnet_scheduler="fcfs";<br>
net_startup_ns="8.0";<br>
net_bw_mbps="5000";<br>
}<br>
<br>
run_params {<br>
num_reqs="5";<br>
payload_sz="16384";<br>
}<br>
<br>
FOO_FORWARDERS and BAR_FORWARDERS are two groups. The lps in these groups have the same type but have different annotations. we call model_net_event_annotated(<br>
int net_id,//SIMPLENET(0)<br>
char const * annotation,<br>
char const * category, <br>
tw_lpid final_dest_lp, //sender->gid is 26,final_dest_lp is 58<br>
uint64_t message_size, <br>
tw_stime offset,<br>
int remote_event_size,<br>
void const * remote_event,<br>
int self_event_size,<br>
void const * self_event,<br>
tw_lp *sender); <br>
<br>
Then we can achieve the communication between lp26 and lp58.<br>
<br>
For the second questions, is it possible that we use model_net_event() to establish a simple point-to-point connection and
<span style="font-size:11.0pt">we send messages 1M times and take the average?<br>
<br>
Thanks,</span><o:p></o:p></p>

<p class="MsoNormal"><span style="font-size:11.0pt"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt">You are correct that modelnet LPs with different annotations shouldn't be able to communicate through the modelnet interface. Can you send us the configuration file you are using, along with the net_id, annotation,
final_dest_lp, and sender->gid values for the call that misbehaves? We'll try to reproduce on our end.</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt">The startup parameter in simplenet represents local sender-side overhead on a packet granularity. So one way to estimate the startup is to get an average per-call time (on the sender side) of very small (word-sized)
messages. I.e. measure calling send(fd, buf, 8, flags) 1M times and take the average.</span><o:p></o:p></p>
