What do you mean? We have no real time application
like a flight simulator. We're using CERTI to connect some discrete event
simulation systems, in this case three instances of SLX ( FYI http://www.wolverinesoftware.com/
).

All three federates plus the rtig run on a single
machine, which has 4 cores ( 2 opterons ) and is connected to 100Mb/s network.
Can't check as savannah is down. I'm
using the cvs checkout from yesterday. Was this bugfix included?

of tick are you using in your federate?
Can't tell you at this moment as this
is encapsulated in a wrapper dll, for which i don't have the source. I
will ask a partner later today.

Btw, unfortunatly i'm not able to share the source
and the SLX simulation system is windows only.
Thanks for your support, Michael

How long does this simulation run (elapse time)?
I mean I want to check how many time advancing steps
per second you get.
thus we need:
3 federates:
are they all tree time regulating and time
constrained?
I bet they are from the message they send.
SimulationTime 40000 units
Lookahead 0.5
you mean 0.5 unit of time compared to your
40000 unit duration right?
Elapsed (Wall Clock) Time : ??
We lack some network topology figures, do each federate run
on a same machine or are they on separate hosts.
Where is the RTIG running? Does it shares a host with one
or several
federate?
If some federate (or the RTIG) are running a the same machine
it would be interesting to know if this machine is mono-processor/core
or multi-processor/core.
> rtig:
RTIG stats looks OK.
RTIG has sent 4.9Mio to each Federate
and received 2.5Mio from each of them.
Note the unit shown by RTIG may be misleading
5305663b means 5305663 bytes and not bits.
This makes aggregate sent volume of 14.7 Mio
and 7.5 Mio received.
This may be relatively high figures depending on the elapse time
for this simulation.
What is the speed of your network 100Mb/s?
