Linx Benchmark Download
Alcibiades Balasubramaniam
The download has been tested by an editor here on a PC and a list of features has been compiled; see below. We've also created some screenshots of LinX to illustrate the user interface and show the overall usage and features of this CPU benchmarking program.
LinX is designed to be a simple interface for Intel Linpack Benchmark. It checks stability of the system and can detect hardware errors. The main point of Linpack is to solve systems of linear equations. It is designed as a benchmark to test the performance of a system in GFlops - billions of floating point operation per second.But it is also the most stressful CPU testing program to date and is a great tool to determine CPU stability. One and the same system of equations is solved repeatedly; if all results match each other - the CPU is stable, otherwise the instability is obvious, since the same sytem cannot produce different solutions.
Features of LinX
- Advanced settings: Settings menu to configure 32/64-bit mode, number of threads, priority class, data alignment and OS memory.
- Automatic error control: Test can be automatically stopped if an error is detected.
- CPUs: Supports Intel and AMD CPUs.
- Documented features: Simple text document included to provide information on every feature.
- Easy setup: Little time required to get familiar with the features offered.
- Error-detection: Boasts automatic error control to stop the test once an error is detected.
- HyperThreading: Supports Intel HyperThreading technology.
- Importing reports: Ability to import reports generated by Everest and Speedfan.
- Intensive testing: Tests the system through intensive tests that may reveal hardware errors.
- Problem size configuration: Main window allows for configuring the problem size and number of runs.
- System repairs/upgrade info: Provides the right information in case the system needs repairs or an upgrade.
- System stability assessment: Tests system stability and detects potential hardware errors.
- User-friendly approach: Differentiates from other similar tools with its user-friendly approach.
- User-friendly interface: Clean interface with intuitive menus for beginner and experienced user.
Linpack is a benchmark and the most aggressive stress testing software available today. Best used to test stability of overclocked PCs. Linpack tends to crash unstable PCs in a shorter period of time compared to other stress testing applications.
I am looking for a quick and easy program to estimate FLOPS on my Linux system. I found HPL, but getting it compiled is proving to be irritating. All I need is a ballpark estimate of the FLOPS, without needing to spend a day researching benchmark packages and installing dependent software. Does any such program exist? Would it be sufficient to write a C program that multiples two floats in a loop?
The question is what do you mean by flops? If all you care about is how many of the simplest floating point operations per clock, it is probably 3x your clock speed, but that is about as meaningless as bogomips. Some floating point ops take a long time (divide, for starters), add and multiply are typically quick (one per fp unit per clock). The next issue is memory performance, there is a reason the last classic CRAY had 31 memory banks, ultimately CPU performance is limited by how fast you can read and write to memory, so what level of caching does your problem fit in? Linpack was a real benchmark once, now it fits in cache (L2 if not L1) and is more of a pure theoretical CPU benchmark. And of course, your SSE (etc) units can add floating point performance too.
As you mention cluster, we have used the the HPCC suite. It takes a bit of effort to setup and tune, but in our case the point wasn't bragging per se, it was part of the acceptance criteria for the cluster; some performance benchmarking is IMHO vital to ensure that the hardware works as advertised, everything is cabled together correctly etc.
The Phoronix Test Suite is the most comprehensive testing and benchmarking platform available that provides an extensible framework for which new tests can be easily added. The software is designed to effectively carry out both qualitative and quantitative benchmarks in a clean, reproducible, and easy-to-use manner. The Phoronix Test Suite can be used for simply comparing your computer's performance with your friends and colleagues or can be used within your organization for internal quality assurance purposes, hardware validation, and continuous integration / performance management.
This security baseline applies guidance from the Microsoft cloud security benchmark version 1.0 to Virtual Machines - Linux Virtual Machines. The Microsoft cloud security benchmark provides recommendations on how you can secure your cloud solutions on Azure. The content is grouped by the security controls defined by the Microsoft cloud security benchmark and the related guidance applicable to Virtual Machines - Linux Virtual Machines.
When a feature has relevant Azure Policy Definitions, they are listed in this baseline to help you measure compliance with the Microsoft cloud security benchmark controls and recommendations. Some recommendations may require a paid Microsoft Defender plan to enable certain security scenarios.
Features not applicable to Virtual Machines - Linux Virtual Machines have been excluded. To see how Virtual Machines - Linux Virtual Machines completely maps to the Microsoft cloud security benchmark, see the full Virtual Machines - Linux Virtual Machines security baseline mapping file.
The benchmarks, offered free for CIS members in the form of PDFs, are not directly usable by a scanning tool, but they are human readable. They do offer some benchmarks in an XCCDF1 format, that can be used by tools, but they are reserved for paying members. These benchmarks, even if they were to be available, do not contain the automation and remediation steps required to change a server state to reach compliance. That is why Red Hat produces the scap-security-guidelines package, which contains what is necessary to scan for compliance, automate and remediate the results.
[1] As explained by the National Institute of Standards and Technologies (NIST), XCCDF is a specification language for writing security checklists, benchmarks, and related kinds of documents. An XCCDF document represents a structured collection of security configuration rules for some set of target systems.
Also, cyclictest is used for latency measurements. If you are in interested in CPU throughput measurement (likely since you are looking at top output), there are other benchmarking programs like lmbench geared towards that.
We have both GB5 and GB4 results in our benchmark database. GB5 was introduced to our test suite after already having tested 25 CPUs, and so the results are a little sporadic by comparison. These spots will be filled in when we retest any of the CPUs.
ab is a tool for benchmarking your Apache Hypertext Transfer Protocol (HTTP) server. It is designed to give you an impression of how your current Apache installation performs. This especially shows you how many requests per second your Apache installation is capable of serving.
Yes, it exists, and yes, it's as good as fans have been hoping for. We'll get more in depth on that shortly, but with the two most important questions surrounding this album finally answered after four years of anticipation, that leaves a third one: why a sequel? The easy conclusion is that Raekwon needed a benchmark-- that he couldn't just put together any slapdash collection of skits and weedcarrier features and b-grade beats, then slap the words Cuban Linx on the cover. So while some people might read this album's title as a gimmicky hook to lure in bring-NYC-back nostalgists, it actually acts more as a reassuring seal of quality from an MC who some people think lost his way the moment he released Immobilarity without a single RZA beat.
Before you start using iperf3, you need to install it on the two machines you will use for benchmarking. Since iperf3 is available in the official software repositories of most common Linux distributions, installing it should be easy, using a package manager as shown.
Then on your local machine which we will treat as the client (where the actual benchmarking takes place), run iperf3 in client mode using -c flag and specify the host on which the server is running (either using its IP address or domain or hostname).
After about 18 to 20 seconds, the client should terminate and produce results indicating the average throughput for the benchmark, as shown in the following screenshot.
