Hardware

Ashish K. Singh, Mayura Deshmukh, and Neha Kashyap describe on the Dell blog the performance of Intel Broadwell processors with HPC applications, Weather Research and Forecasting (WRF) and NAnoscale Molecular Dynamics (NAMD). "Additional cores, along with the higher memory frequency support in Intel Broadwell processors, improve the performance of HPC workloads specifically for compute sensitive workloads like NAMD. The performance of memory bandwidth sensitive workloads like WRF increase up to the 16 core processors, but the performance improvement for the 20 and 22 core processors is not as significant due to the lower memory bandwidth per core", they say.

Applications

"We need HPC order to analyze, model, and understand all this big data", says Emmett Coin in Dzone. All modern HPC efforts concur that we need huge numbers of processors to get the required performance. But advances in processor efficiency can seriously hinder the performance of these processor arrays. According to Coin, probably the very best solution is to develop smarter parallel programmes. Parallelization is, after all, in its infancy. Better parallel programmes are needed. Read further...
