cuda, from nvidia, provides c/c++ extension programming functions to use geforce graphics processors for general purpose computing. the graphics can have tens to hundreds of processing elements that can be easily used for parallel computing. the first benchmark, cudamflops1, demonstrates some best and worst case performance using varying data array size and increasing processing instructions per data access. a double precision version is now available where most but not all speeds are much slower than using single precision. there are three scenarios: new calculations - copy data to graphics ram, execute instructions, copy back to host ram update data - execute further instructions on data in graphics ram, copy back to host ram graphics only data - execute further instructions on data in graphics ram, leave it there the benchmark program can also be used as a graphics processor reliability/burn-in test via a command parameter specifying running time. numeric results are checked for consistent values and errors are reported - example results. performance monitoring benchmarks and other tests were carried out whilst running windows perfmon performance logging to measure cpu and i/o activity on a one second sampling basis. for such as disk and lan activity, measurements used were bytes read and written along with reads and writes (blocks transferred), or packets sent and received over a network. the statistics help to explain why performance is different from expectations. file description monitor1.htm usb and firewire disk and cpu activity copying files using

code as shown under files, most zip files now include c++ source code, some having assembly code using sse, sse2 and 3dnow instructions. assembly code using standard instructions is included in the source for whatcpu, memspd2k, busspd2k and fftgraf. whetstone benchmark source codes are in whets.bas (basic), whetsvb.txt (visual basic), whetsvb.xls (visual basic/excel spreadsheet), whets.for and whetd.for (single and double precision fortran), onlinetests.zip (html/java). there is also whets.c, a general c/c++ version, with timers for various computer systems. these can be obtained via oldones.htm . see new programs for various benchmark source codes as compiled to run at 64 bits. some of these also include 64 bit assembly code. historic data and older benchmarks speed measurements provided are in terms of kilo (thousands) of instructions per second (kips), millions of instructions per second (mips) and/or millions of floating point operations per second (mflops). cpu mhz is also shown, when available. file description cpumix.htm processor speed calculations in kips, based on mixes of instructions for commercial and scientific applications for some computers from pre-1960 to the 1970's. view mips.htm published speed claims for more than 2000 computers produced between 1980 to 1996. costs and other configuration details are also shown. details of ibm’s larger mainframes and pc cpus up to 2004 have also now been included in the latter. view whetstone.htm whetstone benchmark results mainly 1970's to 1990's. from 1980's results include derived mips and mflops ratings. an extra section has been added just for pcs, to include results up to 2006. view oldones.htm numerous older files including cpu, memory, disk and graphics benchmarks to run via dos and os/2, older versions with additional facilities, source codes and results. view about roy e-mail: [email protected] 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 (new home) , roy has created others for family and friends: roy longbottom ancestry - roylongbottom.org.uk/ancestry/ son’s ceramic tile showroom -
