Hi Matthieu,

Which OS are you running? Can you see the usage for all of the 4 cores when
you run MAP and/or PAR?

Thanks,
/Mikhail

I don't use EDK but I do use webpack 10.1.02. During map and par I can
see it using two processors. I have a quad core system. Using fedora 8
and fedora 11.

The following commands use the 2 processors :-xst, map, par, trce,
netgen. Andy

Thanks Andy. This is interesting. It seems to say that somehow OS(?)
combines cores in pairs so that a 4 core system really looks as a 2 core
system of which Xilinx uses only half...

I use the EDK on a 64bit Ubuntu 9.10 and it works fine, no crashes yet...
