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, > /Mikhail > >

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... /Mikhail
