[openib-general] building and running IBMgtsim?

[Eitan Zahavi]

Hi Chris,

Sorry for my late response on this:

The simulator is a standalone "server" where clients connect to it 
through a TCP/IP socket.

OpenSM which is not built with "sim" vendor (using --with-osmv=sim 
--with-sim=<prefix used for ibmgtsim install>)
will not try to connect to the simulator but will go to the real IB 
network instead.

So you need a second "simulator" install of OpenSM.
You can simply clone the GIT tree and
./autogen.sh
./configure --with-osmv=sim --with-sim=<prefix used for ibmgtsim 
install> --prefix=<somewhere>
make
make install

RunSimTest -f OsmTest.sim.tcl -c OsmTest.check.tcl -t IS1-16.topo -o 
<somewhere>/bin/opensm

Actually OsmTest is a test that currently fail (due to last changes in 
InformInfo),
but any other *.check.tcl/*.sim.tcl pair should work.
