AMD multi-core programming

I want to start to write applications(C++) that will utilize the additional cores to execute portions of the code that have a need to perform lots of calculations and whose computations are independent of each other. I have the following processor : x64 Family 15 Model 104 Stepping 2 Authentic AMD ~1900 Mhz running on Windows Vista Home premium 32 bit and Opensuse 11.0 64 bit.

On the Intel platforms , I've used the following APIs Intel TBB, OpenMP. Do they work on AMD and does AMD have similar APIs.what has been your experience?

+4 A:

OpenMP and TBB are both available also for AMD - it is also a compiler question. E.g. see linux TBB on AMD.
I think the latest development on this end is to use the graphic card via CUDA or similar APIs- but this depends on the nature of your calculations. If it fits, it is faster than the CPU anyway.

CUDA is very specific business indeed, since the GPU are optimized for 1 operation applied to several 'datum' at once.

My laptop has a Nvidia card (6150 Go)... how can i get started ?

From my pov you can not.http://www.nvidia.com/object/cuda_learn_products.html

Is there any link where someone has tried TBB on a AMD and discussed instrumentation results or given some performance benchmarks?Is there a AMD equivalent of the TBB library at developer.amd.com ?

For the record, TBB also works well on AMD x64 hardware.
