GCC vs. Clang Compiler Benchmarks On POWER9 With Raptor's Blackbird

While for Intel x86_64 with the latest compilers it’s a very competitive race between LLVM Clang and GCC, how is that battle playing out on the IBM POWER9 front? Using the interesting Raptor Blackbird with IBM POWER9 4-core / 16-thread CPU, here are some recent benchmarks I did between GCC 9, GCC 10, and LLVM Clang 8.

GCC 10 Compiler Picks Up New Scheduler Model & Cost Tables For AMD Zen 2 Processors

While AMD developers published their “Znver2” compiler patches for Zen 2 originally back in November, months ahead of the recent Ryzen 3000 series launch, this compiler support was incomplete as it re-used the existing scheduler model and costs table of Znver1. Now though one of SUSE’s compiler experts who often works in cooperation with AMD has published the new Znver2 scheduler model and costs table for Zen 2…

Fedora Developers Discuss Raising Base Requirement To AVX2 CPU Support

An early change being talked about for Fedora 32, due out in the spring of next year, is raising the x86_64 CPU requirements for running Fedora Linux. When initially hearing of this plan, the goal is even more ambitious than I was initially thinking: AVX2…

Should Ubuntu Use The BFQ I/O Scheduler?

The BFQ I/O scheduler is working out fairly well these days as shown in our benchmarks. The Budget Fair Queueing scheduler supports both throughput and low-latency modes while working particularly well for consumer-grade hardware. Should the Ubuntu desktop be using BFQ by default?..

GCC 10 Lands OpenRISC Support For Floating Point Instructions

When it comes to open-source processor ISAs, RISC-V currently captures much of the spotlight but OpenRISC continues chugging along as another open-source CPU architecture. The OpenRISC GCC compiler back-end and other software tooling also continues to move along for this architecture that’s been in the works since 2000…
