Matrix multiplication on PC-s Preliminary test 96/10/23 (see also: bench_bm_mm_ws.txt) All this is unchecked (what is f77, does it call g77; where are the libraries, etc.) (f77 seems to use a conversion to C.) CPU times can be compared to the workstation benchmarks WITHOUT precompiled BLAS libraries. Table generated by using a dummy tempd_linux.f and using the command "time ". TABLE 1. Program: p25 (simple do-loops, vector loop inside). ------------------------------------------------------------------------ Machine Opt. level ND N CPU (sec) MFLOPS ------------------------------------------------------------------------ Pentium 100 MHz f77 1 400 400 28 4.6 16 MB (Linux) 2 26 5 3 59 ? g77 1 25 * 5 2 25 5 3 25 5 ------------------------------------------------------------------------ * The time overhead for generating the matrices is 0.2 sec. (Obtained by running the program with the matrix multiplication loops deleted. All other loops and calls were retained.)
