I need to run a series of program execution simulations both on MIPS and ARM processors, for that I'm using a benchmark called MPSoCBench. In total there will be over 200 simulations, so I created a bash script to execute it one by one and save the output to a file. However, for some reason, it is not redirecting the output like it should be.
Here is the bash script:
source env.sh
echo "Simulation start"
./MPSoCBench -p=mips -s=stringsearch -i=noc.lt -n=1 -r > output/MIPS/stringsearch/stringsearch-1.out
./MPSoCBench -p=mips -s=stringsearch -i=noc.lt -n=2 -r > output/MIPS/stringsearch/stringsearch-2.out

./MPSoCBench -p=arm -s=susancorners -i=noc.lt -n=8 -r > output/ARM/susancorners/susancorners-8.out
echo "Simulation end"
So for example, if I run: ./MPSoCBench -p=mips -s=susansmoothing -i=noc.lt -n=1 -r
the terminal output is:
[['mips'], ['1'], ['susansmoothing'], ['noc.lt']]
./platform.noc.lt.x susansmoothing.mips.x 1

If I try to redirect this output to a file with the command: ./MPSoCBench -p=mips -s=susansmoothing -i=noc.lt -n=1 -r > output/MIPS/susansmoothing/susansmoothing-1
Then some weird stuff happen, first there is still terminal output:

[['mips'], ['1'], ['susansmoothing'], ['noc.lt']]
It is like some lines are redirected and other are not, what is going on here? Perhaps multi-threading? If so, how can I wait for the program to finish executing and then copy the terminal output to a file?
Thank you.
Answer
The program output appears to be on STDERR instead of STDOUT. Give this a try:
./MPSoCBench -p=mips -s=dijkstra -i=noc.lt -n=2 -r > output/MIPS/dijkstra/dijkstra-2.out
changes to
./MPSoCBench -p=mips -s=dijkstra -i=noc.lt -n=2 -r > output/MIPS/dijkstra/dijkstra-2.out 2>&1
Note the 2>&1 added after the redirect. It sends STDERR -> STDOUT.
