Today Univa announced availability of its much anticipated Preemption feature for Univa Grid Engine. Preemption, in combination with Universal Resource Broker, gives users the unprecedented ability to “pause” workload, services, or containers in the system on a moment’s notice in order to run a higher priority application. This is the first time a preemption feature has been able to work with big data applications.
UCX is a collaboration between industry, laboratories, and academia to create an open-source production grade communication framework for HPC applications. “The path to Exascale, in addition to many other challenges, requires programming models where communications and computations unfold together, collaborating instead of competing for the underlying resources. In such an environment, providing holistic access to the hardware is a major component of any programming model or communication library. With UCX, we have the opportunity to provide not only a vehicle for production quality software, but also a low-level research infrastructure for more flexible and portable support for the Exascale-ready programming models.”
The latest High Performance Conjugate Gradients (HPCG) Benchmark list will be announced in a special session this week at ISC 2015. This is the third list produced for the emerging benchmark designed to complement the traditional High Performance Linpack (HPL) benchmark used as the official metric for ranking the Top 500 systems.
“Modern HPC systems are complex due to the sheer number of components that comprise them. With this complexity comes the reality of failures. One particular damaging and little understood type of failure is silent data corruption (SDC). SDC occurs when program state changes without intervention of the application or the system. An understanding of how applications handle state perturbations and how these corrupted values propagate through HPC applications is key to mitigating its effects. In this talk, we present our results from fault injection experiments on an Algebraic Multigrid linear solver.”
Today Panasas announced ActiveStor 18, its latest generation hybrid scale-out NAS appliance. By adopting 8 terabyte drive technology, ActiveStor 18 increases scalability to more than 20 petabytes and 200 gigabytes per second. According to Panasas, ActiveStor 18 also offers increased CPU power and twice the storage cache capacity to further accelerate mixed workload performance.
