<p>Hi John,</p>
<div>
For example, this is the code in
codes/doc/example_heterogeneous/example.c:<br>
void handle_forwarder_fwd(<br>
forwarder_state * ns,<br>
forwarder_msg * m,<br>
tw_lp * lp){<br>
// compute the forwarder lpid to forward to<br>
int mod;<br>
const char * dest_group;<br>
char * category;<br>
if (ns->is_in_foo){<br>
mod = num_bar_forwarders;<br>
dest_group = "BAR_FORWARDERS";<br>
category = "ping";<br>
}<br>
else{<br>
mod = num_foo_forwarders;<br>
dest_group = "FOO_FORWARDERS";<br>
category = "pong";<br>
}<br>
<br>
// compute the ROSS id corresponding to the dest forwarder<br>
tw_lpid dest_lpid = codes_mapping_get_lpid_from_relative(<br>
ns->id % mod, dest_group, "forwarder", NULL, 0);<br>
<br>
forwarder_msg m_fwd = *m;<br>
msg_set_header(forwarder_magic, FORWARDER_RECV, lp->gid, &m_fwd.h);<br>
// here, we need to use the unannotated forwarding network, so we<br>
// use the annotation version of model_net_event<br>
model_net_event_annotated(net_id_forwarding, "foo", category, dest_lpid,<br>
payload_sz, 0.0, sizeof(m_fwd), &m_fwd, 0, NULL, lp);<br>
<br>
ns->fwd_node_count++;<br>
}<br>
the sender lp is the forwarder in FOO_FORWARDERS,id is 26,dest_lpid id is 58,means the dest lp is the forwarder in BAR_FORWARDERS,they have same net type with different annotations.We
We don't modify the code but the configuration file. We changed
the type of forwarder to two different types, they can still
communicate. By the way, if we change the second parameter to
"foo", "bar", or any string, model_net_event_annotated() can
always run with success.<br>
<br>
<br>
For <span style="font-size:11.0pt"> startup parameter in
simplenet, what's the exact means of this parameter? Now we
want to use simplenet to construct a complex network.<br>
<br>
Thanks,<br>
</span><br>
Lei<br>

should run that or a similar benchmark on a real (not

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

<p>Hi John,<o:p></o:p></p>
<p>Thanks for your response.<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>

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>

## forwarding network parameters<br>
packet_size="4096";<br>
modelnet_scheduler="fcfs";<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>

are correct that modelnet LPs with different

the modelnet interface. Can you send us the

<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
