The default Linux mitigations for the new Microarchitectural Data Sampling (MDS) vulnerabilities (also known as "Zombieload") do incur measurable performance cost out-of-the-box in various workloads. That's even with the default behavior where SMT / Hyper Threading remains on while it becomes increasingly apparent if wanting to fully protect your system HT must be off...

Of Intel's many open-source projects, taking a central role at this year's Intel Open-Source Technology Summit was Clear Linux. Most Intel open-source efforts mentioned during the event point back to Clear Linux in some capacity and at OSTS2019 we finally heard some of the companies that are beginning to make use of Clear Linux...

A few days back I posted a number of Intel OpenCL benchmarks between their former Beignet and new "NEO" Linux compute stacks that was done using a Skylake NUC for the Iris Pro 580 graphics.
