Evaluating the Power Efficiency and Performance of Multi-core Platforms Using HEP Workloads

As Moore’s Law drives the silicon industry towards higher transistor counts, processor designs are becoming more and more complex. The area of development includes core count, execution ports, vector units, uncore architecture and finally instruction sets. This increasing complexity leads us to a place where access to the shared memory is the major limiting factor, resulting in feeding the cores with data a real challenge. On the other hand, the significant focus on power efficiency paves the way for power-aware computing and less complex architectures to data centers. In this paper we try to examine these trends and present results of our experiments with Intel® Xeon® E5 v3 (code named Haswell-EP) processor family and highly scalable High-Energy Physics (HEP) workloads.

  • AES-GCM Encryption Performance on Intel® Xeon® E5 v3 Processors

    This case study examines the architectural improvements made to the Intel® Xeon® E5 v3 processor family in order to improve the performance of the Galois/Counter Mode of AES block encryption. It looks at the impact of these improvements on the nginx* web server when backed by the OpenSSL* SSL/TLS library. With this new generation of Xeon processors, web servers can obtain significant increases in maximum throughput by switching from AES in CBC mode with HMAC+SHA1 digests to AES-GCM.
