Threadripper 3970X Performing Better On Windows Relative To Linux – Thanks To Microsoft Or Zen 2?


AMD --

With the AMD Ryzen Threadripper 3970X benchmarks on Windows 10 and Linux, Ubuntu 19.10 and other common distributions were just ~2% faster than the Microsoft OS and Clear Linux was just ~10% faster, based on 80+ benchmarks carried out. Those margins are much closer than we have seen with past iterations of Threadripper, but is that due to the Zen 2 microarchitecture and the improved topology of the new Threadripper CPUs or due to Microsoft’s scheduler changes and other software improvements made in Windows 10 November 2019 Update? Here are some benchmarks.

One of the frequent questions that came up following that Windows 10 vs. Linux benchmark article yesterday was whether the relatively close Windows 10 vs. Linux performance was due to AMD Zen 2 / Threadripper 3970X itself or the ongoing software improvements Microsoft has been working on around its scheduler and other areas for dealing with today’s HEDT processors.

For answering that question at least in part, I fired up some additional Windows benchmarks on the same system when instead running the Microsoft Windows 10 October 2018 Update as opposed to the latest feature release, Microsoft Windows 10 November 2019 Update. Here’s a look at how comparing last year’s and the current feature builds panned out:

The demanding SPECjbb 2015 was the biggest benefactor of the new Windows 10 release on Threadripper 3970X with a massive 30% improvement while 7-Zip and Renaissance’s Java tests saw 12~18% improvements and other workloads at 8% or less. Shown are just the tests with measurable differences between the Windows 10 releases. With over 80 tests ran, the vast majority of them saw a negligible change in performance. In a few cases, the older Windows 10 build offered slightly better performance.

So while the Windows 10 November 2019 Update did help some workloads on Threadripper 3970X, the vast majority of the tests were within a margin of error to the previous Windows 10 release. Thus for the more competitive Windows 10 performance to Linux on the new Threadripper parts appear to be largely due to hardware improvements as opposed to Microsoft’s software optimizations over the past year.

In case you missed it, see the 3970X Windows vs. 5 Linux distribution benchmarks from yesterday. If you enjoy our new and original content 365 days per year and often exclusive Linux hardware testing, consider showing your support this Black Friday / Cyber Monday.


US Air Force says they are developing an Open Source Jet Engine





The economies of scale generally dictate that anything produced in large enough numbers will eventually become cheap. But despite the fact that a few thousand of them are tearing across the sky above our heads at any given moment, turbine jet engines are still expensive to produce compared to other forms of propulsion. The United States Air Force Research Laboratory is hoping to change that by developing their own in-house, open source turbine engine that they believe could reduce costs by as much as 75%.

USB Updates In Linux 5.5 Help Intel Ice Lake, NVIDIA Xavier + More – But No USB 4.0 Yet


HARDWARE --

Earlier this week as part of his series of pull requests, Greg Kroah-Hartman has submitted the USB subsystem updates for the in-development Linux 5.5 kernel.

Among the USB changes for this next kernel release, which will debut as stable in early 2020, include:

– Various improvements to the USB Type-C port manager code.

– XHCI mainline support for the NVIDIA Tegra194 (Xavier) SoC.

– Various code clean-ups to the longstanding USB Lego Infrared Tower driver.

– The mainline kernel is disabling UAS for JMicron SATA enclosures. There have been out-of-tree patches for years and bug reports around JMicron SATA enclosures with incorrect block sizes or other alignment issues. Disabling USB Attached SCSI (UAS) should workaround these JMicron problems. Merged is the four year old patch that’s been carried in distribution kernels and elsewhere while now finally landed.

– Allowing host run-time power management for Intel Ice Lake xHCI as another Ice Lake power optimization.

– Various other USB driver updates, gadget driver improvements, and code clean-ups in the USB area of the kernel.

The complete list of USB changes can be found via this pull request.

Not found in Linux 5.5 is USB 4.0 support. While the USB 4.0 specification was finalized just in September, already last month Intel posted initial USB 4.0 Linux kernel driver patches. The quick turnaround is in large part due to USB 4.0 being based on Thunderbolt. The USB 4.0 Linux patches continue to be worked on by Intel engineers and others but just not ready in time for Linux 5.5. With USB 4.0 devices not expected until late 2020, there still is plenty of time ahead for the Linux support to settle down.

OSGeoLive Distro Opens Doors to Geospatial Worlds

If you ever have considered investigating or working with elements of the geospatial world, check out the latest edition of
OSGeoLive.

OSGeoLive is a Linux distribution that runs directly from a bootable DVD or USB thumb drive. You also can load a pre-made virtual machine disk file (vmdk) that runs in a VMware Workstation or VirtualBox environment. Or you can install it the old-fashioned way as a dual-boot or sole operating system on a hard drive.


OSGeoLive 13.0 offers a prelease peek into the latest distro update.

Version 13.0 of the OSGeoLive GIS software collection was just released at the International Conference for Free and Open Source Software for Geospatial (FOSS4G) in Bucharest, Romania.


Whichever approach you take, OSGeoLive gives you a complete Linux OS. If your work or hobby requires steady hands-on access to geospatial tools, you could use it as your primary OS.

This review was originally published on Sept. 6, 2019, and is brought to you today as part of our Best of ECT News series.

Aside from the basic system tools and a few standard graphic and accessory applications, you would have to add from general software repositories applications such as office suites, audio and video tools. Adding your own to top off the specialized geospatial software that is included would give you a bloat-free computing platform.

This distro can serve your side interests, such as boating or traveling, by giving you portable and convenient access to navigational maps and other geospatial technologies, including storing, publishing, viewing, analyzing and manipulating data. It includes sample datasets, documentation and free world maps.

OSGeoLive is based on Lubuntu Linux and runs the LXDE desktop (Lightweight X11 Desktop Environment). It is interesting to note that the latest Lubuntu release earlier this year switched to the LXQt desktop (the Lightweight Qt Desktop Environment). LXQt was formed from the merger of the LXDE and Razor-qt projects.

OSGeoLive is based on Lubuntu Linux and runs the LXDE desktop.


When I downloaded the virtual machine disk edition last week I got OSGeoLive 13.0, which the
Open Source Geospatial Foundation officially released today, Sept. 6, for DVD and USB as well.

Release highlights:

  • New applications MapCache, GeoExt, t-rex, actinia;
  • Additional Python modules like Fiona, rasterio, cartopy, pandas, geopandas, mappyfile;
  • Improved documentation and four new translations, now supporting: English | Deutsch | Espaol | Suomi | Franais | Italiano | 日本語 | Hungarian; and
  • Version updates to many of the included packages.

Geographic Information Management

This distro, sponsored by the OSGeo Foundation, is a specialty Linux offering with a following comprised of data specialists and science researchers as well as mapping enthusiasts. Geospatial technology refers to all of the technology used to acquire, manipulate and store geographic information.

The foundation is a not-for-profit organization supporting geospatial open source software development, promotion and education. The current versions of this distro reflect a refining of the number and types of included software. The focus seems to be packaging only leading geospatial and standard Linux system tools and applications. The emphasis pushes quality over quantity.

The software selections include some 50 high-quality geospatial open source applications installed and preconfigured with sample datasets. You also get free world maps and various project overviews with step-by-step quickstart guides for each geospatial application.

System requirements are fairly forgiving, thanks to the lightweight desktop environment the distro uses. OSGeoLive runs on a broad collection of legacy hardware.

Minimum suggested system resources are 1 GB RAM, although it’s better to have 2 GB if you plan on trying the Java-based applications). You need a 1-GHz i386 or AMD64 compatible CPU. No hard drive is required, but a hard drive is needed if you want to have an installation that lets you save system settings and personal data.

Note that you can run this distro from the bootable DVD or USB installation. However, no persistent memory is available. You could get around that limitation by burning the ISO to a writable DVD or running the virtual machine disk version within your existing operating system installed on the hard drive.

OSGeoLive has an impressive inventory of geospatial software. Many of these titles are foundation projects. Some are standalone installed applications. Others are Web app connections that launch in the default Firefox Web browser from menus and desktop icons.


OSGeoLive library of four specialty apps

OSGeoLive has a library of specialty apps not found in other Linux scientific distros.


Spatial Toolbox

The Jupyter Notebook is a Web application to create and share documents that contain live code, equations, visualizations and explanatory text. Uses include data cleaning and transformation, numerical simulation, statistical modeling and machine learning.

Mapnik is a toolkit for rendering maps with clean, soft feature edges provided by quality anti-aliasing graphics, intelligent label placement and scalable, SVG symbolization. Mapnik is used to render the OpenStreetMap main map layers. It often is embedded in Python applications that deliver their maps over the Internet.

MapSlicer is a graphical application for online map publishing. You can use it to create overlays of standard maps like OpenStreetMap, Google Maps, Yahoo Maps or Bing Maps. Maps it creates can be visualized in 3D by Google Earth. Publishing your maps only requires uploading the automatically generated directory with tiles into your Web server.

The OTB/Monteverdi-based open source visualization tool handles your compression needs. This package is based on the Orfeo ToolBox (OTB). This is a CNES (French Spatial Agency) open source image processing library and the derived software Monteverdi. Monteverdi-Compression takes advantage of the visualization and image processing tools available in OTB and Monteverdi.

R Statistics uses the
R Project for Statistical Computing. It is a free software environment for statistical computing and graphics.

Plotting Your Course

Tools for navigating and course planning are an integral part ofr the geospatial toolset this distro handles. For instance,
GpsPrune is a tool for viewing, editing and converting coordinate data from GPS systems.

Use GPSPrune for planning trips or analyzing the tracks recorded by GPS receivers. It uses OpenStreetMap imagery to show recorded tracks and waypoints. It provides a variety of tools to let you edit, crop and prune the data points. It also has functions for correlating photos and audio files to the coordinates using the file timestamps.

GpsPrune uses Gpsbabel, if available, to read data directly from a GPS receiver and can send the edited data back to the receiver too.

JOSM or Jaffa OpenStreetMap Editor, is a desktop editing tool for OpenStreetMap geodata created in Java.

Marble is a virtual globe and world atlas. It is similar to a desktop globe. You can pan around and measure distances with it.

OpenCPN Chart Plotter Navigation is used by thousands of boaters as their main navigational tool for use under way or as a planning tool.

OpenStreetMap is the free wiki world map. Together you have land and sea routes completely covered.

Weather is another element critical to geospatial awareness.
zyGrib is a program to download and visualize weather forecast data in the standard GRIB distribution format.

Default GIS Tools

Geographic Information System (GIS) tools are essential for handling geospatial surroundings on a computer. OSGeoLive gives you several options by default.

GRASS GIS, commonly referred to as GRASS (Geographic Resources Analysis Support System), is a free and open source Geographic Information System (GIS) software suite used for geospatial data management and analysis, image processing, graphics and maps production, spatial modeling and visualization.

gvSIG Desktop is a powerful, user-friendly, interoperable GIS used by thousands worldwide. It provides vector and raster file support, databases and remote services. This desktop offering provides a variety of tools to analyze and manage your geographic information.

OpenJUMP GIS is a Java-based vector and raster GIS and programming framework that enables users to display, edit, analyze and conflate geographic data. A similar tool is
Open Source Desktop GIS for creating, editing, visualizing, analyzing and publishing geospatial information.

The
SAGA GIS, or System for Automated Geoscientific Analyses, is a GIS computer program used to edit spatial data.

Another similar tool is
uDig. It provides a complete Java solution for desktop GIS data access, editing and viewing.

More Geospatial Essentials

Databases and browser clients are the backbone of the geospatial toolset included in OSGeoLive platform.

pgAdmin III is a tool for working with the PostgreSQL Tools. It adds heightened functionality and convenience in handling PostgreSQL content.

Rasdaman (Raster Data Manager) is an Array Database Management System. In this distro Rasdaman is coupled with EarthLook to showcase standards-based services on Big Earth Data — in particular, spatial-temporal coverage.

SHP2pgsql is a tool that generates an SQL script from ESRI shape and DBF files suitable for loading into a PostGIS enabled database. Spatialite GUI is an open source graphical user interface (GUI) tool supporting SpatiaLite, a spatial extension to SQLite that provides vector geodatabase functionality.

The Browser Clients menu is perhaps the largest collection of specialized geospatial tools in this distro. It is a collection of standalone tools you otherwise would have to track down and install on your own.

  • GeoNode is a Web-based application and platform for developing geospatial information systems (GIS) and for deploying spatial data infrastructures (SDI);
  • Cesium is a geospatial app with a simple workflow to create 3D maps of geospatial data for visualization, analysis and sharing;
  • GeoExt is a JavaScript Toolkit for Rich Web Mapping Applications based on ExtJS and OpenLayers;
  • GeoMoose 3 is a Web Client JavaScript Framework for displaying distributed cartographic data;
  • Leaflet is a JavaScript library for mobile-friendly interactive maps;
  • Mapbender is a Web-based geoportal framework to publish, register, view, navigate, monitor and grant secure access to spatial data infrastructure services;
  • OpenLayers is a high-performance, feature-packed library for creating interactive maps on the Web;
  • Geomajas is a collection of free and open source GIS libraries, tools and APIs for a complete end-to-end Web mapping solution.

In a Nutshell

OSGeoLive is a unique Linux distro. It pulls together a large library of Linux tools and applications that support geospatial workloads. It is not designed to be a general usability Linux operating system, but if you add the software it’s missing, you can happily use it for other computing tasks.

I was particularly intrigued by some of its standalone applications and Web app offerings. Browsing through this distro’s feature tools was a fun-filled discovery experience.

Nothing needed to be set up or configured. One click led to another. With each new screen came interesting information that teased my inquisitive mind. The experience actually sparked an interest in the world of geospatial elements.

Deepin Linux Manager Talks Huawei Partnership, Spyware Accusations And Tantalizing Teases For 2020





Deepin simultaneously exists as a beautiful yet perpetually misunderstood Linux distribution. It shatters misconceptions about how sleek and modern a Linux desktop can look, but struggles to shake repeated accusations of being spyware, likely because of its Chinese origins and business ties with Huawei. Despite the controversy, Deepin is poised to begin thriving thanks to its inclusion on select Huawei laptops in China, and a new version of the distro and desktop environment right around the corner.
