[Links of the day] 24/10/2016 : HPC scratchpad memory architecture, Flexible Package manager

• Spack : flexible package manager designed to support multiple versions, configurations, platforms, and compilers. Cool feature : its non destructive, which means you can have multiple version co-existing in the same system. [Github]
• Runnemede : energy-optimized research architecture using scratchpad ( software managed ) rather than HW cache. They achieve almost a 4x energy improvement vs standard design. [slides]
• Efficient HPC Data Motion via Scratchpad Memory : Earlier paper demonstrating the efficiency of scratchpad rather than cache for Data motion in HPC systems.
