Links of the day 18 - 03 - 2015

Today's links 18/03/2015: NVDIMM , Dynamic CPU Cache allocation, NAS + Bigdata Analytic, DPDK packet generator
  • Atomic Sector Updates inSoftware for Persistent Memory : Intel proposal to adress atomic sector update as byte addressable persistent storage is great but limited when you want to do large write.
  • Priority-Based Cache Allocation in Throughput Processors : interesting approach that propose to dynamically vary the amount of cache allocated to processors based on the pollution rate. Allowing cache friendly process to benefit from greater cache real estate [slides]
  • Qumulo : start up proposing a file system with Analytic capability directly embedded within the NAS [spec]
  • MoonGen : fully scriptable high-speed packet generator build on DPDK and LuaJIT. It can saturate a 10 GbE connection with 64 byte packets on a single CPU core while executing user-provided Lua scripts for each packet. It also features precise and accurate timestamping and rate control.
