Hello,
I'm currently trying to learn how to use Intel TBB and I tried to write a simple short program using parralel_reduce.
However, the parallel version is 10 times slower than the sequantial one...
I really can't understand why the parallel version is that slower, could you help me figure out why please ?
Here are both of my programs :
I compiled them with g++ under Fedora 12 linux and my computer has a dual core processor.
Thank you for your help.
