I think that LAPACK is the engine under the hood of popular LA commercial packages ... And the good thing of ATLAS is that it is automatically tuned, I mean, it adapts the matrix operations to the processor capabilities, like cache-sizes in order to subdivide the matrices onto smaller ones to proceed with the operations. I understand all this stuff will give the z/OS the ability to execute convex optimizations, recommendation systems. etc But when there will be GPU-like cards?
