C# on multicore - C# / C Sharp

Padu

Hi,

I'm a newbie to C# and I haven't dig into multi-threading in .net (I have
some experience with MT in delphi and c++).
Let's say I have one of these new pentium D multicore. If I start a program
that has 2 threads, will they execute each in a different core? Is there any
support in the language to control in which CPU a thread will execute?
In a more general sense, how .net uses multi-core/multi-cpu systems?

Cheers

Padu

Hello Padu,

use Process.ProcessorAffinity to set which CPU each tread need to use
or create thread pool for each processor

Hello Padu,

BTW, if you are starting you app in SMP box (2 CPU) you CLR start works in
server mode and its responsible for CPU thread management
