This morning Sun Microsystems will officially introduce their Niagara 2 processor, which consists of eight processing cores and is capable of handling 64 threads simultaneously. It's official name is the Sun UltraSPARC T2 and it will be unveiled at their Executive Briefing Center in Menlo Park, California. We were invited to this event, but we had run into scheduling problems at the last minute though we do have some information to share with you in this technical brief.
While the Linux 2.6.23 kernel is only weeks into development, it's already generated quite a bit of attention. From the merging of the Completely Fair Scheduler (CFS) to the -rc2 kernel being "the new -rc1", the Linux 2.6.23 kernel is certainly in store for being an ornate release. Adding to this attention has been a stable user-space driver API and virtualization improvements (KVM, Xen, and LGuest). With all of this activity surrounding the Linux 2.6.23 kernel we've decided to conduct a handful of benchmarks comparing the Linux 2.6.20, 2.6.21, 2.6.22, and 2.6.23 kernel releases so far.
Last night at a media party during OSCON and Ubuntu Live 2007, Intel had announced the release of Intel Threading Building Blocks 2.0, which marks the GPLv2 open-source availability of the code. James Reinders had made this presentation going through a look at multi-core processors and parallel programming followed by this announcement. To drive interest in TBB 2.0, Intel has announced an open-source competition for integrating TBB into open-source projects where you can win a multi-core laptop. With the Intel party just ending a few hours ago, we have enclosed many of Reinders' slides and we will be sharing more information shortly. One extra tid-bit is that Intel is working with multiple (yet to be named) game developers on integrating Threading Building Blocks 2.0. Several distributions will also be shipping Intel's TBB 2.0.
It wasn't until last week during a meeting with Sun that some new light was shed on the Solaris Check Tool and as a result we decided to explore this tool further. Sun's Check Tool is a bootable CD that lets the user know whether the hardware they have installed is likely to work with Solaris or not. If a third-party driver is needed for a particular piece of hardware, the Sun Check Tool will even provide a link to the driver needed. There are currently a few rough spots with the tool, but improvements are planned and in this article we will share more information on this program that can tell you in a matter of minutes whether you'll face a hardware compatibility nightmare or will be running Solaris/Solaris Express with ease.
Let's face it, humans are expensive. The cost of humans combined with the dominance of single-threaded applications in the market place spells trouble for companies wishing to seek the greatest return on investment for their latest multi-core servers. Pervasive Software, however, has developed an alternative for companies not wishing to spend valuable man hours on rewriting their software in order to benefit from a symmetric multi-processing environment. DataRush from Pervasive Software is a Java framework that allows software developers to quickly and easily create new or existing applications that are hyper-parallel. Pervasive's DataRush had made its debut last week at JavaOne 2007 and in this article, we have a few words about this unique framework.
We've been meaning to deliver benchmarks from the Intel Core 2 Duo E6400 for some time now, but with the new site, the upcoming Solaris hardware support, quad/octal core benchmarking, and the variety of different articles we have been working on, things have been quite hectic around here. However, with Fedora 7 Test 4 now being available, we have finally published our Core 2 Duo E6400 Linux results.
This afternoon the Intel camp is sharing some new public information in regards to Penryn and Nehalem. The Penryn family will support increased performance per given clock cycle, increased power frequencies, extended energy efficiency, a 45nm High-K metal gate process technology, and a range of processors against all target markets. The Intel 45nm High-k process will result in new features and an elevated level of performance while sticking with cost effective die sizes. These new processors will also introduce the SSE4 instruction set and deliver new levels of energy efficiency.
In this article we will be looking at the impact of CONFIG_NO_HZ/Dynamic Ticks, which will be found in the Linux 2.6.21 kernel. The option has been available as a patch for quite a while, but not until Linux 2.6.21-rc1 had it been merged into the upstream kernel. When enabled, there will only be timer ticks when they are needed. The end-user benefit is cooler-running processors and increased power savings. We have investigated this change with a notebook and desktop computer.
Over the weekend a blizzard has hit Michigan causing sub-zero temperatures, inches of snow, and zealous winds. This winter weather has caused the closing of shopping centers and community activities; public transportation systems and the Gerald R. Ford International Airport have also come to a halt. However, we took this opportunity to make the best of it with natural sub-zero overclocking. With the Abit AW9D i975X motherboard, an Intel Pentium 4 processor, 2GB of OCZ's Flex XLC PC2-9200 memory, and cooling provided by Mother Nature, we set off on a spontaneous overclocking adventure. Have you ever seen a motherboard in a snow-bank?
For only being a release candidate the Linux 2.6.20 kernel has already generated quite a bit of attention. On top of adding asynchronous SCSI scanning, multi-threaded USB probing, and many driver updates, the Linux 2.6.20 kernel will include a full virtualization solution. Kernel-based Virtual Machine is a GPL software project that has been developed and sponsored by Qumranet. In this article we are offering a brief overview of the Kernel-based Virtual Machine for Linux as well as offering up in-house performance numbers as we compare KVM to other virtualization solutions such as QEMU Accelerator and Xen.
While 64-bit support is now considered common for both Intel and AMD processors, many Linux (as well as Windows) users are uncertain whether to use a 32-bit or 64-bit operating system with there being advantages for both paths. With this being the last Phoronix article for 2006, we decided to take this opportunity to look at the common question of whether to use 32-bit or 64-bit software. In this article, we will be comparing the i386 and x86_64 performance with Ubuntu 6.10 Edgy Eft and Ubuntu 7.04 Feisty Fawn Herd 1 to see how the numbers truly stack up.
On November 2, 2006 the embargo for Intel's Core 2 Extreme Quad QX6700 was lifted which resulted in a slurry of reviews covering this flagship desktop processor. However, this morning happens to be an important date for Supercomputing 2006 and it serves as yet another milestone for Intel Corporation. This morning Intel will be introducing the Xeon 5300 series, or perhaps better known by its codename of Clovertown. At Phoronix we have had these processors in-house for over a week now and today are able to share our thoughts on these quad-core server/workstation processors as we test them under GNU/Linux.
Last month Intel had announced the Woodcrest Xeon 5100 series processors for use on servers and workstations, while just days ago, Intel finally officially launched their Core 2 Duo selection. Today at Phoronix we have taken a performance look at Intel's Xeon 5150 Woodcrest processor in both single and dual configurations as well as comparing its performance against the Intel Xeon 5000 Dempsey.
A higher level of computing performance with lower clock speeds, and lower power consumption; is that too good to be true from our blue friends at Intel? With Intel proudly brazing their Core 2 products (namely the Conroe) on this late-night adventure, we have up our technical primer on this Pentium replacement.
Intel's Core Duo T2400 has a maximum operating frequency of 1.83GHz, 65nm process, 2MB of L2 cache, and 667MHz FSB; however, how does this dual-core component fare under Linux? We have taken a look at the Intel Core Duo T2400 in conjunction with the Lenovo ThinkPad T60, and have comparison results today against the previous Pentium M 750 1.83GHz.
Intel was first to adopt DDR2 memory when they had launched their LGA-775 socket nearly two years ago with the Grantsdale and Alderwood Chipsets. Intel Corporation is first again to introduce the latest in memory technology: FB-DIMM. FB-DIMM is short for Fully Buffered Dual Inline Memory Module, and is primarily designed for mission-critical server environments that require maximum performance with minimal errors. FB-DIMMs are designed to bring the best traits from DDR2 memory while combining a new point-to-point serial memory interface. Some of the key benefits for Fully Buffered DIMMs include enhanced reliability, greater bandwidth, improved scalability, and higher capacity per memory channel. We at Phoronix have the first performance preview of the new DDR2 FB-DIMM memory modules on the Xeon Greencreek platform.
After having presented our preview of the AMD Socket AM2 last week, today we finally have our first set of numbers ready to publish. Our first Linux AM2 performance report comes in way of the AMD Sempron 3400+ and AMD Athlon 64 X2 4200+.
Making headlines for months now has been countless rumors in regards to Advance Micro Device's M2/AM2 Socket. AMD's Socket AM2 is designed to bring forward several changes -- most notably, the adoption of DDR2 -- and here at Phoronix we have all the facts. With this being the morning of the long awaited pre-Computex launch, we also have up some details when it comes to AMD's finest on Linux. Continue on with our AMD AM2 Series Preview.
Intel's SpeedStep Technology has origins tracing back to the days of the Mobile Pentium 3 and Pentium 2 processors with Geyserville Technology. However, at that time, the 1GHz Pentium 3 model was the fastest and required 1.7V for operation, and its maximum power consumption was 34W! Since that time, many of the processor technologies have been phased out and have brought new features in the Pentium 4, Celeron M, Pentium M, and most recently the Core Duo series. However, over six years later SpeedStep Technology remains in their mobile platform as well as some Pentium 4 and Pentium D processors. At hand today are the results from our most recent (EIST) Enhanced Intel SpeedStep Technology investigation.
Introduced way back with the launch of Advanced Micro Devices Athlon 64 processors was Cool 'n' Quiet Technology, as the successor to PowerNow! Today at Phoronix we are looking at the performance of AMD's Cool 'n' Quiet under Linux when it comes to the CPU temperature, power consumption, and overall desktop performance and usage.
In our previous piece yesterday, we had covered the performance benefits of using a 16MB cache on 2.5-inch mobile devices compared to the traditional 8MB capacity and overall we were pleasantly surprised by our penguin findings. Today we are going to be looking again at mobile memory performance under Linux but rather than the form of permanent storage, we are examining various memory configurations and its effect on the Pentium M performance. In this article we will be testing the system in 512MB, 1GB, and 2GB DDR2 PC2-4200 configurations.
DFI's 855GME-MGF motherboard has been receiving a fair amount of attention in recent months due to its Socket 479 Pentium M support. When an Intel Pentium M is utilized in conjunction with one of these Socket 479 desktop motherboards, the high performance level can be quite shocking. Although we're running the Pentium M 750 notebook at stock speeds in this article, we've posted some results to demonstrate Intel's mobile capabilities under Linux. Hitting the bench today is an IBM/Lenovo ThinkPad R52 with 1.86GHz Pentium M processor, i915 Express Chipset, 512MB DDR2, and an ATI X300 utilizing GCC 4.0 and the Linux 2.6.12 kernel.
As most of you are aware, AMD's Athlon 64 flagship single core is currently the San Diego, in fact the Athlon 64 FX-57 is based upon the San Diego. The key difference between the San Diego and its Venice counterpart is the amount of L2 Cache. But just how well do these two cores compare clock-for-clock? In this review will be running two of these CPUs at 2.0, 2.2, and 2.6GHz to see the performance difference between the two AMD cores.
Deleron, CellyD, Celery D, or whatever you would like to call the new Intel Celeron D processors, they undoubtedly have some enthusiasts talking over its Prescott core. In this article today, we got our hands on the new Intel Celeron D 320 that runs at 2.4GHz and utilizes the Prescott core with 90 nm process.
