benchmark.py goes in the t-crest folder. Running it requires Python 3.

benchmarking.patch is applied in the patmos folder using

git apply benchmarking.patch

A folder called benchmark must exist in the t-crest folder.

The benchmarks were run on SSPM-device branch. Take notice that configuration and programming happens and works.

benchmark.py

import subprocess

bufferSizes = [2**x for x in range(1, 7)]
pairs = range(1, 5)

for pair in pairs:
	for bufferSize in bufferSizes:
		file = open('patmos/c/libsspm/sspm_benchmark.h', 'w')
		headerContent = """
#define SENDER_RECEIVER_PAIRS ({pair})

#define CHANNEL_BUFFER_CAPACITY ({bufferSize})""".format(pair = pair, bufferSize = bufferSize)

		print(headerContent)
		
		file.write(headerContent)
		file.close()
		
		configProc = subprocess.run("make -C aegean AEGEAN_PLATFORM=default-altde2-115-9core config".split())
		
		configProc.check_returncode()
		
		uploadProc = subprocess.run("make -C patmos -B APP=sspm_speed_test comp download".split(), stdout=subprocess.PIPE, universal_newlines=True)
		
		uploadProc.check_returncode()
		
		outputFilename = 'benchmark/p{pair}b{bufferSize}'.format(pair = pair, bufferSize = bufferSize)
		file = open(outputFilename, 'a')
		file.write(headerContent)
		file.write('\n')
		file.write(uploadProc.stdout)
