Platforms & Libraries
Runs on many architectures and more are constantly added: from large parallel machines (IBM SP and BlueGene, Cray XT, Altix, Nec SX) to workstations (HP, IBM, SUN, Intel, AMD) and single PCs running Linux, Windows(?), Mac OS-X, including clusters of 32-bit or 64-bit Intel or AMD processors with various connectivity (gigabit ethernet, myrinet, infiniband…). Can use pre-compiled and optimized libraries (such as MKL for Intel CPUs, ACML for AMD CPUs, ESSL for IBM machines) already installed in the machine or, alternatively, download automatically all components and compile/link at the same time of the source.
