The process is fully automated, private and safe. PC Pitstop runs diagnostics on your PC to identify things that might help improve performance. PC Pitstop can help you get your PC in top form - running fast, stable and secure. The results can be saved in the online Results Database. Need for speed measures the performance of your CPU using a Dhrystone benchmark. This web-based application can be accessed from any system and requires no special software other than Macromedia's Flash Player for your Microsoft Internet Explorer (5.0 or greater) web browser. At the core of the MonitorsDirect ToolKit are a series of test patterns and instructions on how to evaluate any CRT or LCD monitor.
The MonitorsDirect ToolKit is designed to help evaluate monitor quality, diagnose possible problems, and help properly adjust the display image. The Linpack Benchmark is a numerically intensive test that has been usedįor years to measure the floating point performance of computers. This applet runs the Linpack Benchmark in Java. Programs running in various hardware and software configurations.Īll the tests can be performed online as well as locally. The CaffeineMark is a series of tests that measure the speed of Java OS: Win95/98, Mac OS, Solaris, OS/2 Download HomepageRating: 4/5 - 70 Kb - Test Online Multimedia | Monitor | Network | Video | Misc | Monitoring | Online The relative machine precision usually the smallest positive number such that fl( 1.0 - eps ) < 1.0, where fl denotes the computed value and eps is the relative machine precision.Common | CPU | Hard Disk Drive | RAM | Hard Disk Drive 2 If this quantity is much larger than 1, the solution is probably incorrect. The Norm Res should be about O(1) in size.
The test is based on || Ax - b || / ( || A || || x || eps) where eps is described below. The time in seconds to solve the problem, Ax=b.Ī check is made to show that the computed solution is correct. For this problem there are 2/3 n^3 + n^2 floating point operations. A floating point operation here is a floating point addition or a floating point multiplication with 64 bit operands. Millions of floating point operations per second. The result is reported in millions of floating point operations per second (MFLOP/s, sometimes simply called FLOPS). The solution is obtained by Gaussian elimination with partial pivoting, with 2/3
They measure how fast a computer solves a dense N by N system of linear equations Ax = b, which is a common task in engineering. The LINPACK Benchmarks are a measure of a system's floating point computing power.
