POWER9 & ARM Performance Against Intel Xeon Cascadelake + AMD EPYC Rome

Filed under
Graphics/Benchmarks

For those wondering how ARM and IBM POWER hardware stack up against AMD's new EPYC "Rome" processors and that of Intel's existing Xeon "Cascade Lake" processors, here is a round of tests from the POWER9 Talos II, Ampere eMAG, and Cavium ThunderX in looking at the cross-architecture Linux CPU performance currently in the server space.

Our AMD EPYC Rome benchmarks this month have been focused on the performance compared to earlier AMD EPYC and Intel Xeon processors, but given the broader architecture support on Linux and there also being significant interest in the likes of IBM POWER / OpenPOWER thanks to more open-source designs when paired with motherboards from Raptor Computing Systems, here are some initial numbers for ARM and POWER9 performance against the new x86_64 server CPUs.

A POWER'ful Announcement Is Expected Tomorrow

  • A POWER'ful Announcement Is Expected Tomorrow Changing The Open-Source Landscape

    For those interested in IBM's POWER architecture and/or open-source hardware prospects, an industry-shaking announcement is expected to happen Tuesday morning.

    Taking place Tuesday and Wednesday in sunny San Diego is the OpenPOWER Summit focused on the open-source POWER ecosystem. There will be keynotes tomorrow from IBM, Microsemi, Raptor Computing Systems, and the OpenPOWER Foundation. Beyond the usual fluff and what not at most industry events / keynotes, there is going to be a very exciting announcement made tomorrow morning in kicking off this event.

Open source POWER ISA takes aim at Intel and Arm for accelerator

  • Open source POWER ISA takes aim at Intel and Arm for accelerator-driven computing

    IBM announced the release of the POWER instruction set architecture (ISA) as an open standard at the OpenPOWER Summit in San Diego on Tuesday. This announcement comes six years after the formation of the OpenPOWER Foundation, which aimed to foster the creation of hardware from third-party vendors that integrates the POWER architecture in the datacenter.

    While the POWER ISA was itself licensable following the creation of the OpenPOWER Foundation in 2013, that came at a cost. Now, the POWER ISA is available royalty-free, inclusive of patent rights. IBM is releasing a soft core reference implementation of the POWER ISA, and reference designs for Open Coherent Accelerator Processor Interface (OpenCAPI) and Open Memory Interface (OMI) architecture-agnostic compute accelerators.

Linux 5.4 Lands A Number Of Memory Management Fixes

While mid-way through the Linux 5.4 development cycle with RC4 due out on Sunday, a number of memory management fixes just hit the mainline kernel. Andrew Morton's pull request was merged on Friday night and he noted, "Rather a lot of fixes, almost all affecting mm/" Indeed there were memory management fixes in this pull ahead of 5.4-rc4. Changes include a zRAM race condition fix, avoiding access to uninitialized memory maps, allow dropping transparent huge-pages (THP) from the page cache, and other fixes in this area including the possibility of a kernel crash.

  • AMD Zen 2 Improvements For LLVM Have Been Held Up For Months By Code Review

    Back in February for LLVM Clang 9.0 was the initial AMD Zen 2 "znver2" enablement, but like the GCC support at the time it was the very basics. With time GCC picked up Zen 2 scheduler improvements and other work while sadly in the case of LLVM the improvements are still pending. Back in August, AMD's Ganesh Gopalasubramanian sent out the znver2 scheduler model for LLVM for Zen 2 CPUs but a focus on the EPYC 7002 "Rome" processors. "There are few improvements with respect to execution units, latencies and throughput when compared with znver1. The tests that were present for znver1 for llvm-mca tool were replicated. The latencies, execution units, timeline and throughput information are updated for znver2."

  • Python Add Lists

    This tutorial covers the following topic – Python Add lists. It describes various ways to join/concatenate/add lists in Python. For example – simply appending elements of one list to the tail of the other in a for loop, or using +/* operators, list comprehension, extend(), and itertools.chain() methods. Most of these techniques use built-in constructs in Python. However, the one, itertools.chain() is a method defined in the itertools module. You must also see which of these ways is more suitable in your scenario. After going through this post, you can evaluate their performance in case of large lists.

  • 3D using Godot

    It is time for another installment of Godot (previous entries: introduction, 2D). This time, I have dived into the world of 3D. The goal is to recreate parts of an old time favorite: Kosmonaut. Something I remember playing a lot on my dad’s 286 with amazing EGA graphics. The state of the game when writing can be seen in the short screen capture below. This is more of a tech demo status than a full game at the moment, but I hope you will still find it interesting. You can also get the complete source code. [...] Once we have a world with a track (the grid map), we add a player to the scene (the yellow blob in the image above – I need to learn Blender to create a proper ship). The player scene contains the ship – and the camera. This means that the camera follows the player automatically – very convenient. The player script is responsible for this ship’s movements based on user input. Inputs can either be pressed for a long time, used for sideways movement, or just tapped (i.e. the release is ignored), used for jumping. Each of the inputs are mapped to a keyboard key (or other input device) in the Project Settings dialog, under the Input Map tab. This feels a bit awkward to me and makes me lose the feeling of flow – but I don’t know how to do it better.

Xfce 4.16 development phase starting

In the 4.14 cycle we tried to do a 1:1 port of what used to be our Gtk2 desktop environment, avoiding visual changes. In the 4.16 cycle we plan to harmonize the appearance of certain elements that either became inconsistent through the port or already were inconsistent before (e.g. toolbars or inline toolbars). We will also play with client-side decorations where we feel it makes sense (for instance replacing the so-called XfceTitledDialog, that is used for all settings dialogs with a HeaderBar version). Before anyone gets too excited (both positively or negatively): It is not planned to redesign more complex applications (like Thunar) with Headerbars in 4.16. We will however try to keep the experience and looks consistent, which means gradually moving to client side decorations also with our applications (please note that client side decorations are not the same as HeaderBars!). Through this change e.g. “dark modes” in applications will look good (see the part about the Panel below). Now before there is a shitstorm about this change I would kindly ask everyone to give us time to figure out what exactly we want to change in this cycle. Also, switching to client-side decorations alone is not a big visual departure – feel free to also dig through the client-side decorations page if you want to read/see more on this. Read more
