Probably fairly well. On Intel Macs, the BLAS in the Accelerate framework is just an old version ATLAS with the serial numbers filed off (literally; they removed some of the APIs that identify the specific version of ATLAS used). I don't think they've updated it particularly vigorously in recent years, but I could be wrong. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco ------------------------------------------------------------------------------ All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity, and more.
