In this episode, the Radio Free HPC teams looks at Henry Newman’s recent straw proposal for better resource management for Linux in HPC. His Enterprise Storage Forum column on this topic got Slashdotted recently, and the question remains: does Linux want to be more like the mainframe? Rich and Dan take him to task to learn more.
With next-generation technology like non-volatile memories and PCIe SSDs, there are going to be more resources in addition to the CPU that need to be scheduled to make sure everything fits in memory and does not overflow. I think the time has come for Linux – and likely other operating systems – to develop a more robust framework that can address the needs of future hardware and meet the requirements for scheduling resources. This framework is not going to be easy to develop, but it is needed by everything from databases and MapReduce to simple web queries.”
