  • Why Use Containers, Kubernetes, and OpenShift for AI/ML Workloads?

    Containers and Kubernetes are proving to be very valuable in helping accelerate Artificial Intelligence (AI) and Machine Learning (ML) lifecycle for organizations worldwide. ExxonMobil, BMW, Volkswagen, Discover Financial Services, Ministry of Defense (Israel), Boston Children’s Hospital, are some organizations have operationalized Red Hat OpenShift, industry leading Kubernetes-based container platform, to accelerate data science workflows, and build intelligent applications. These intelligent applications are helping achieve key business goals and providing competitive differentiation.

    In a recent blog, I explained how these emerging cloud-native technologies are playing a vital role in helping solve ML Lifecycle execution challenges, and accelerate the delivery of intelligent applications. You may be thinking…”ok, so where do we start to learn about this topic?”

    To help you get started on this journey, we have developed a short video that explains in under three minutes how containers, Kubernetes, and OpenShift can accelerate AI/ML initiatives for your organization. Whether you are working at your desk, driving, riding on a train, walking, or something else, this quick video will do the job for you! As always, feedback is highly appreciated.

A Look At The GCC Compiler Tuning Performance Impact For Intel Ice Lake

For those wondering if it's worthwhile for performance recompiling your key Linux binaries with the microarchitecture instruction set extensions and tuning for Ice Lake, here are some GCC compiler benchmarks looking at that impact for the Core i7 1065G7 on the Dell XPS 7390. In particular, this article is looking at the affect on generated benchmark binaries when built under the following CFLAGS/CXXFLAGS configurations: -O3 -march=skylake - Just optimizing for conventional Skylake processors. -O3 -march=skylake-avx512 - Optimizing for Skylake AVX-512 processors like Skylake-SP/Skylake-X. The Skylake AVX-512 enables use of the AVX512F, CLWB, AVX512VL, AVX512BW, AVX512DQ and AVX512CD instructions. -O3 -march=icelake-client - Optimizing for Icelake client/desktop processors. New instructions exposed here not found with Skylake/Skylake-AVX512 include AVX512VBMI, AVX512IFMA, SHA, CLWB, UMIP, RDPID, GFNI, AVX512VBMI2, AVX512VPOPCNTDQ, AVX512BITALG, AVX512VNNI, VPCLMULQDQ, and VAES. Note there is also the "icelake-server" target for future Ice Lake Xeon Scalable processors where additionally PCONFIG and WBNOINVD are flipped on. Read more

PHP 7.4 Performance Benchmarks Show A Nice Improvement - But PHP 8.0-dev Is Running Even Faster

PHP 7.4 is due to be released next week as the annual major iteration to PHP7. Like we have seen through the PHP7 releases, while new features continue to be tacked on for this popular web-based programming language the performance has continued evolving. Here are the latest benchmarks of PHP 5.6 through PHP 7.4 while also looking at the PHP 8.0-dev performance that is in development on Git master. Outside of the performance realm, PHP 7.4 is another exciting update thanks to finally introducing FFI support. The Foreign Function Interface for PHP allows accessing C structs/functions/variables from native PHP code for making it easier to interact with C libraries from PHP. In addition to the headlining FFI support of PHP 7.4, this next release has a preload function to preload functions/classes to speed-up the loading of scripts by 30~50%, language alterations, TLS 1.3 support in PHP OpenSSL streams, and a variety of other smaller additions.
