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.
