- Runs on almost every conceivable current architecture (really! also cell phones and playstations): 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…). Fully exploits math libraries such as MKL for Intel CPUs, ACML for AMD CPUs, ESSL for IBM machines.
GPU-enabled version available via the QE-GPU add-on package.
