Try the perf command. It will give you the load and performance per core. Sis
is fairly accurate for basic benchmarking ...------ Ursprungligt

simulatorHi Jiri,Thanks for the suggestion. It works. However, it looks like it
just simulates the instruction. I am looking for a cycle-accurate simulator and
can provide the performance information on each core. Do you know any?Best,Duc

Hi Sebastian,
Thank you. I didn't notice that.
I recompile with SMP enabled, and the application doesn't
run successfully in the TSIM-LEON3 simulator. Below is the
error message:
Initializing
and
starting from 0x40000000
CPU 0 in error mode (tt=0x80, trap instruction)
(In trap table for tt=0x02, illegal instruction)
70150 40000020 91d02000 ta 0
start + 0x20
The thing is, the same code will work if I compile with SMP
disabled. When the SMP is enabled, the simulator will crash
like above, even with the simple hello world application.
Have anyone here run into a similar issue? Or do you know
any other leon3 (or sparc) simulator that I can try?
You can try with sis:
sparc-rtem6-sis -leon3 -m 4 hello.exe
Should work without problems. For SMP, you need the '-m 4' switch
to enable 4 cores ...
Jiri.
Best regards,

Just set "RTEMS_SMP = True" in your config.ini:
