Hi,

I'm a newbie here. A friend of mine got a new dual core processor
laptop. I was wondering if compiling standard applications using gcc
will build binaries which can fully utilize the hardware - 686
instruction set with SMP. I'm assuming here that the application is
multithreaded.
If it does, is there an flag to be passed during compile time?

gcc 4.2 supports OpenMP, requiring appropriate #pragma omp directives, along with -fopenmp flag.
