Benchmarking programs on Linux
for an assignment we need to benchmark our implementations with different optimizations and p开发者_开发知识库arameters. Is there a feasible way of benchmarking little programs on the linux command line (I know of time) with different parameters which gives me the time data as CSV or something similiar? Output could be something like:
Implementation Time
A 23s
B with -O3 2Threads 15s
B with -O3 4Threads 10s
I'm pretty sure that I've seen something like that on some professors slides but I cant remember who or when it was...
Why not using time
command inside a bash
script, something like :
#!/bin/bash
NPROG=`cat proglist | wc -l`
for i in `seq 1 ${NPROG}`
do
PROG=`sed -n "${i}p" proglist`
ARG=`sed -n "${i}p" arglist`
TIME=`{ time ${PROG} ${ARG}; } 2>&1 | grep real | awk '{print $2}'`
echo "${TIME} ${PROG} ${ARG}"
done
where proglist
is a text file containing the programs to execute
A
B
B
and arglist
is a text file containing the arguments, something like :
-a 1 -b 2
-f "foo"
-f "bar"
The output of the script will look-like :
0m32.000s A -a 1 -b 2
1m12.000s B -f "foo"
5m38.000s B -f "bar"
