Create a build directory and cd into it. Then call
cmake /path/to/numabench/sourceIf you have root access on the machine I recommend to use "REALTIME_BENCHMARKS=TRUE". You can do this by adding this switch to the cmake call:
cmake -DREALTIME_BENCHMARKS=TRUE /path/to/numabench/sourceIf you want to use a different compiler (GCC >= 4.3 is recommended) you can set the CC and CXX environment variables before you call cmake.
maketo compile numabench.
Run the Benchmark¶
Usage ./numabench [OPTION]... Measure throughput and latency of memory in steps of 1GB -h, --help print this message -o <filename> output measurements to a file instead of stdout --firstCpu <id> --cpuStep <id> --size <GB> --only <test function>
You might have to use the --size option. Numabench will try to allocate as much memory as it thinks it can get. If that is too much it will crash. You can use the --size switch to specify how much memory numabench may allocate.
Without the -o switch numabench will output the results as it measures them to stdout. This format is not useful for any further processing. Use the -o <filename> switch to create a CSV (tabs actually) file which contains the results. You can then use the supplied processOutput.sh script to create a PDF using gnuplot internally:
./numabench -o data ./processOutput.sh data
