PC Reliability and Burn-in Tests

Diagnostic test programs tend to check all functions but at a slow rate and via DOS. These tests run via Windows and exercise the hardware at high speeds using a wide variety of number values or data patterns with results being checked for correctness. All Benchmarks/Tests can be run via command lines to log results and exit automatically. A series of commands in a BAT file can produce a comprehensive system burn-in test, in some cases for more than one CPU. See documentation in ZIP files and Results below.

Paging Tests

Programs compiled for 32 and 64 bit working are available to demonstrate maximum memory that can be allocated for a single data array within Virtual Memory and measure associated data transfer rates with paging to/from disk. They are normally run initially with lower demands with little or no paging. Other benchmarks can show the impact of paging on a simulated real application handling bitmap images. Latest report is for Vista tests using ReadyBoost, showing significant performance improvements with heavy paging.

About Roy

E-Mail: roy_longbottom@compuserve.com
Roy Longbottom (born 1935) joined an organisation that later became the Central Computer and Telecommunications Agency (CCTA), the British Government computer purchasing department, in 1960.

He was initially a technical consultant on computer reliability. This was followed by a period of responsibility for planning and supervising acceptance trials at departments and universities, then by added responsibility for evaluating new scientific computers (including the first supercomputers). Many of the projects included benchmarks. He then moved on to become a full time Performance Engineer/Consultant with work including sizing of systems, benchmarks and trouble shooting for commercial applications. These included huge mainframe based on-line systems, numerous UNIX configurations and, later, PC networks.

His first involvement in programming was during the acceptance trials period, when he wrote a suite of programs (in Fortran) to exercise all of the hardware via Operating Systems, including checking for correct results. These were used successfully during hundreds of pre-delivery and on-site acceptance tests. Some of the programs (mainly FOPRxx processor tests) were adopted by various suppliers for inclusion in their development tests. His book "Computer System Reliability" was published (Wiley) in 1980.

During the 1980's, for personal gratification, he wrote (and sold) software for the Z80 based Sinclair Spectrum (T/A ROYBOT), the first product being an assembler. This was followed by a sort of Operating System, a graphics package and database manager.

He obtained an early retirement in 1993 then, for a period, acted as a paid consultant (ROYBOT Ltd.). He also spent time on learning "C", Visual Basic and Java to produce versions of the Whetstone benchmark in these languages specifically for PCs. This was followed by the same PC format versions of the other Classic Benchmarks.

In 1997, he arranged for the Classic Benchmarks to be uploaded to Compuserve's Benchmark and Standards Forum. The other benchmarks were written and uploaded during the following period. The material was transferred to the PC Hardware (PCHW) Forum in 1999, then to the new Compuserve PC Hardware Forum in 2004.

Besides producing this site Roy Longbottom's PC Benchmark Collection (Original Home), Roy has created others for family and friends:
