Has anyone tried linking R against an accelerated BLAS like Atlas or K. Goto's BLAS? I know that Goto's BLAS for the Opteron are multithreaded and can use a dual core processor effectively. I presume the same is true for dual core Intel processors.
Yes, I was using ptATLAS (which compiles fine on OS X) and it uses both cores resulting in a bit less than half the time compared to vecLib which doesn't use threads. Cheers, Simon
