Finally, each block from one file is read repetitively, normally involving data cached in main memory.
Sequential reading is then repeated but with blocks selected randomly from the four files. Four files are written, sized in multiples of 10.3 MB, with data blocks comprising 164 different binary patterns, then read, with data checked, for a chosen time.

achieving up to 6 per CPU MHz.ĭrive Test - The program code is essentially the same as used in the acceptance trials mentioned above. Performance is measured in MB/second and MIPS.įloating Point Test - This is another memory/arithmetic exerciser but compiled to use SIMD SSE functions. Integer Test - This memory/arithmetic exerciser comprises 8 write then read and 8 read only tests, using different hexadecimal data patterns, with arithmetic carried out by assembly code, arranged for fast data streaming.

The programs are available, compiled fro both 32 bit and 64 bit systems, to run under Windows or Linux, mainly with run time parameters that can be executed from a BAT or script file, to enable parallel operation of multiple tasks. interval for displaying and logging intermediate results different log files for running multiple copies of a program concurrentlyĥ. data size to test a particular cache or RAM in memory testsĤ. Objectives for these later programs are to automatically check results of numeric calculations or data comparisons, save results in a text based log file and, when appropriate, identify ongoing speed of operation and provide variable parameters to specify:ģ. The programs are based on experience in designing and running stress programs, that were used for acceptance test purposes, on hundreds of computers purchased by the UK Government for Departments and Universities, including mainframes, minicomputers, mini-servers, workstations and supercomputers from the 1970s to the 1990s. Links to download the test programs is provided, also the source code for those who wish to compile them for other systems or modify them for other purposes. Some detailed results are provided plus reference to more comprehensive reports. The programs can either be run standalone or multiple copies of any at the same time. The report provides details of a series of stress tests that cover processor integer and floating point calculations, cache and memory speeds, disk and other drives, including local network traffic, and graphics hardware.
