![]() We are using only one node for our testing, though today's multiprocessor systems in some ways mirror parallel computers from many years ago. NPB or NAS Parallel Benchmarks are a set of computational fluid dynamics applications originally intended to benchmark parallel supercomputers for NASA. More information on the benchmark can be found here. ![]() NAMD is a molecular modeling benchmark developed by the Theoretical and Computational Biophysics Group in the Beckman Institute for Advanced Science and Technology at the University of Illinois at Urbana-Champaign. Linux-Bench runs HardInfo to get another view of common application areas. ![]() HardInfo is well known perhaps because the benchmark is installed by default on many Ubuntu desktop systems. We test OpenSSL performance because it is becoming a de-facto standard application to run. OpenSSL is the technology that secures much of the Internet's data traffic, and is a common server application. The benchmark was created and is maintained by Dr. STREAM is perhaps the seminal memory bandwidth application used for well over a decade. We defined three tests which provide granularity into the performance of most systems available today. You can find archived results, including those from SGI systems, here. It is designed so that, on most systems, it should not need to access RAM and therefore is highly sensitive to processor performance. The high CPU count patch is applied.Ĭ-ray 1.1 is a popular and simple ray-tracing benchmark for Linux systems written by John Tsiombikas. Excluded are the 2D/3D GPU and storage benchmarks because this test suite is run mainly on servers. It is an extremely popular Linux test suite that has a number of component tests like Dhrystone, Whetstone, and shell scripts. Not sure how much RAM is on your system? Use the free -mĬommand and look under the total column for Mem.With roots dating back over 30 years, the byte-unixbench project can now be found on Google Code here. Resides) with a parameter stating that the system has 2048 MB of RAM, and the testing will be run as the Once installed, the simplest way to run Bonnie++ is to use the following command: bonnie++ -d /tmp -r 2048 -u ĭirectory (thus testing the performance of the drive on which /tmp Or install on Fedora, Red Hat, or CentOS with: sudo yum install bonnie++ Install on Debian and Ubuntu with: sudo apt-get install bonnie++ It doesn't come installed on most distros out of the box, but it should be available in the core repositories. ![]() Bonnie++īonnie++ is a free utility that's designed to benchmark file system and hard drive performance. Make sure you aren't doing anything else that might impact the readings, such as tranferring files. Whichever one you use, run the command multiple times to get multiple readings, and then average them together to get a more accurate sense of the performance. Timing cached reads: 3364 MB in 2.00 seconds = 1682.75 MB/sec` To test cached read performance: sudo hdparm -T /dev/sda2 Timing buffered disk reads: 180 MB in 3.00 seconds = 59.96 MB/sec` To test buffered read performance: sudo hdparm -t /dev/sda2 It's also highly configurable - with every test, you can specify different parameters such as how many test instances, how many CPU cores, how aggressive to test, how long to run, etc.Ĭovering all of the various commands and parameters is beyond the scope of this article, but this page on the Ubuntu wiki is an okay starting point. Once installed, stress-ng can test all kinds of stuff, including your CPU, RAM, I/O, network, virtual memory, and more. Install stress-ng on Fedora, Red Hat, and CentOS: sudo yum install stress-ng Install stress-ng on Debian and Ubuntu: sudo apt-get install stress-ng Certain components, especially CPUs and HDDs, will wear out faster when repeatedly stressed. Stress-ngĪs you might be able to glean from its name, stress-ng is a true stress test - it's extremely good for pushing your system to its limits, but because it can be so demanding, we don't recommend running it very often. It also comes in Live CD form called PTS Desktop Live, which lets you run it off of a CD, DVD, or USB drive so you can test any machine's hardware using a "clean" operating system on demand. Best of all, Phoronix is free and open source.
