<p>Hi John,</p>
<p>Thanks for your response.</p>
<p><br>
</p>
<p>For the first question, the configuration is as follows:<br>
</p>
<div>
LPGROUPS {<br>
## cluster foo<br>
FOO_CLUSTER {<br>
repetitions="12";<br>
node="1";<br>
modelnet_simplenet@foo="1";<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,<br>

<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.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></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.<o:p></o:p></span></p>
