Building The Default x86_64 Linux Kernel In Just 16 Seconds

Wednesday 14th of August 2019 07:02:22 AM
It's now been one week since the launch of AMD's EPYC Rome processors with up to 64 cores / 128 threads per socket and better IPC uplift compared to their previous-generation parts. Rome has outperformed Intel Xeon Scalable CPUs in their class while offering better power efficiency and way better performance-per-dollar. One of my favorite metrics has been how quickly the new EPYC 7742 2P can build the Linux kernel...

A Script Making It Easier Turning A FreeBSD Install Into A Working Desktop

Cooling The Raspberry Pi 4 With The Fan SHIM & FLIRC For Better Performance

Tuesday 13th of August 2019 07:30:00 PM
With the Raspberry Pi 4, a passive heatsink is an absolute minimum for running this new ARM SBC unless you want to deal with potentially drastic performance limitations based upon your operating conditions. However, if you will be enduring the Raspberry Pi 4 with significant load for any measurable length of time, an active cooler is almost warranted or otherwise a very capable passive cooler. In this article we're looking at the Raspberry Pi 4 performance with a Fan SHIM as an active fan designed for running on the Raspberry Pi off the GPIO pins as well as the FLIRC as a metal case that passively cools the device.

Intel's Linux Graphics Driver Developers Discover 3~20% Boost For Current-Gen Hardware

Monday 12th of August 2019 10:48:04 PM
Last week was the Intel Gallium driver one line patch to boost performance by 1%. Today's code churn within Mesa for Intel's open-source Linux graphics drivers were larger but also with a more profound performance impact with some workloads now being faster by around 20%. Making this more exciting is that today's round of driver optimizations apply to the very common and mature "Gen 9" graphics hardware...

AMD EPYC Rome Still Conquering Cascadelake Even Without Mitigations

Monday 12th of August 2019 01:43:39 PM
With last week's dramatic EPYC "Rome" launch where AMD has blown past Intel Xeon "Cascadelake" performance in a majority of server benchmarks, helping the successful launch of these Zen 2 server processors has been Intel's repeated delays of 10nm/Icelake CPUs and also the Spectre / Meltdown / Zombieload / Foreshadow mitigations. Out of curiosity, I've run some unmitigated benchmarks for the various relevant CPU speculative execution vulnerabilities on both the Intel Xeon Platinum 8280 Cascadelake and AMD EPYC 7742 Rome processors for seeing how the performance differs.
