So, to run a CPU stability test you have to: The purpose of a processor stability test is to determine how smoothly the CPU works, even if it is under high load. Thus, FPS is a good indicator while running a CPU stability test. However, if the frame rate drops below 30 FPS, it means that something is wrong (for example, the system cannot keep up with the current workload). As a rule, in most cases, browsers render frames at a speed of 60 FPS (although sometimes a slightly lower speed may be acceptable). The number of frames per second (abbreviated as FPS) indicates how fast your browser is able to render new frames.

As you might have guessed, the number of points directly depends on the speed and the test duration. The number of score points indicates how many hashes were computed during the test. Thus, more power and threads will provide higher speed and CPU load (for example, 50% power + 10 threads will result in a 500% load). Since the power and the number of threads almost proportionally affect the speed, a 100% power + 1 thread will give the same speed as 50% power + 2 threads, or 25% power + 4 threads.

The power indicates how much CPU time can be used by one thread (for example, 100% power means full speed without time idle). Multi-core CPUs cope better with the multithreading, this is why in such cases modern processors work faster and get better results. Thus, more threads lead to a higher speed, but at the same time to a higher load. The number of threads determines the number of simultaneous operations for computing hashes. However, you need to remember that for maximum speed you need to use the full power of the CPU (that is, specify as many threads and power as possible). Obviously, a more powerful processor develops a higher speed. The speed measures how fast the processor is, and is measured in the number of hash operations per second. Given that not all processors and devices withstand high loads, it is strongly recommended to gradually increase indicator values. This excludes the use of a fast matrix multiply algorithm like 'Strassen's Method' or algorithms which compute a solution in a precision lower than full precision (64 bit floating point arithmetic) and refine the solution using an iterative approach.Power -5 +5 Start CPU Stress Test What do the indicators mean?Р”В«efore starting the CPU stress test, review the indicators below to understand what they are for. In particular, the operation count for the algorithm must be 2/3 n^3 + O(n^2) double precision floating point operations. In an attempt to obtain uniformity across all computers in performance reporting, the algorithm used in solving the system of equations in the benchmark procedure must conform to LU factorization with partial pivoting. These numbers together with the theoretical peak performance Rpeak are the numbers given in the TOP500.

It does, however, reflect the performance of a dedicated system for solving a dense system of linear equations.Р’В Since the problem is very regular, the performance achieved is quite high, and the performance numbers give a good correction of peak performance.Р”В«y measuring the actual performance for different problem sizes n, a user can get not only the maximal achieved performance Rmax for the problem size Nmax but also the problem size N1/2 where half of the performance Rmax is achieved. This performance does not reflect the overall performanceР’В of a given system, as no single number ever can.

For the TOP500, we used that version of the benchmark that allows the user to scale the size of the problem and to optimize the software in order to achieve the best performance for a given machine. The benchmark used in the LINPACK Benchmark is to solve a dense system of linear equations.

A detailed description and frequently asked questions can be found: Р”Р„ parallel implementation of the Linpack benchmark and instructions on how to run it can be found at.

The LINPACK Benchmark was introduced by Jack Dongarra. LINPACK was chosen because it is widely used and performance numbers are available for almost all relevant systems. As a yardstick of performance we are using the `best' performance as measured by the LINPACK Benchmark.
