probably less about what is typical today and more about what is next ...
ARM is engineering processors for what is next: https://en.wikipedia.org/w/index.php?title=ARM_big.LITTLE&redirect=no newer ARM processors are designed with parallelism explicitly targeted and floating point issues resolved: https://en.wikipedia.org/wiki/ARM_Cortex-A53 https://en.wikipedia.org/wiki/Superscalar_processor https://en.wikipedia.org/wiki/ARM_architecture#VFP http://www.arm.com/products/processors/instruction-set-architectures/index.php http://projectne10.github.io/Ne10/ people are building ARM clusters: http://www.nextplatform.com/2015/02/27/prototype-arm-clusters-muscle-hpc/ http://www.nextplatform.com/2015/06/16/mont-blanc-sets-the-stage-for-arm-hpc/ http://www.montblanc-project.eu/arm-based-platforms people are running Julia on ARM systems and Julia has parallelism as a focus, so there will be a natural nexus.
