There are two multi-processor benchmarks I wrote for windows NT for nt 3.1 the affin.dll is needed... for nt daytona it is not necessary. pt is a benchmark that runs floating and integer ops whet is a multi-threaded whetstone benchmark... these benchmarks are usefull to test mult-processor systems. the executable versions in this file are for daytona.
