[Simflex] Help for installing ultrasparc over linux

I tried running the following job :
[eugen at localhost flexus-test-app]$ ./run-job -fxpt-out flexpoint_000 -cfg
OoO UniFlex.OoO
It did not go smooth ... I am hoping someone can help me out. There is no
benchmark application running on the target machine at this point. But from my
understanding that should not be a problem.
Starting initial flexpoint creation of flexus_test with UniFlex.OoO in

So far I managed to get Linux on the Simics sunfire-bagle configuration. I
automatically login, and start running a benchmark ( bitcount ), a snapshot. (
part of what prepare-test-app is suppose to do).
I need some assistance getting to the next steps:
- do I need to insert SIMICS_magic_instructions into the benchmark code?
- do I need a special compiler that will allow me to cross compile for v9_Linux
that knows about magic_instructions ?
I have a hard time (based on the Getting starting guide) understanding the
relation of what happens on the target system running the simulation and these
steps :
prepare-test-app
create-initial-flexpoints
create-flexpoints
run-timing-jobs
and
run-job
I am sure these are obvious for someone familiar with flexus, but they do not
come out easily from the "Getting Started Guide".
Thank you in advance for your help,
Eugen
