The benchmarks were compiled using a Raspberry Pi Terminal command such as: cc mpmflops.c cpuidc.c -lrt -lc -lm -O3 -o MP-MFLOPS Additional parameters were used for gcc 4.8 and Raspberry Pi 2 - see below. The commands are provided at the start of each C source code. Execute using a Terminal command, for example, ./MP-MFLOPS Results are displayed and saved in text log files - see Example Logs in benchmark folders. ARM-Intel folder contains executables to run on Intel CPUs via Linux and are compiled from the same source codes. For details and example results on ARM and Intel processors see http://www.roylongbottom.org.uk/Raspberry Pi Multithreading Benchmarks.htm NOTE - After unzipping, the benchmark execution file Properties, Permissions needs a “Make the file executable” selection. New PiA7 versions are included to use Raspberry Pi 2 additional features. Example compilation command is: gcc mpmflops.c cpuidc.c -lrt -lc -lm -O3 -mcpu=cortex-a7 -mfloat-abi=hard -mfpu=neon-vfpv4 -lpthread -o MP-MFLOPSPiA7. A second version MP-MFLOPSPiNeon uses the additional -funsafe-math-optimizations parameter to force compilation of NEON instructions. MP-NeonMFLOPS carries out the same calculations using NEON intrinsic functions. A second version of MP BusSpeed is included that avoids using RPi 2 shared L2 cache, that previously lead to exaggerated performance. linpackNeonMP is a demonstration of what not to use to demonstrate MP performance. Benchmarks compiled to use OpenMP are now included. See Raspberry Pi Multithreading Benchmarks.htm. Roy Longbottom March 2015
