xcatperf

xcatperf is a tool to test xcat concurrenty performance.

Setup xcat

wget https://xcat.org/files/go-xcat -O - >/tmp/go-xcat
chmod +x /tmp/go-xcat
/tmp/go-xcat

Setup nytprof dependency

cd /tmp
wget http://search.cpan.org/CPAN/authors/id/P/PE/PEREINAR/File-Which-0.05.tar.gz
tar xvfz File-Which-0.05.tar.gz
cd File-Which-0.05/ && perl Makefile.PL
make && make install
wget http://search.cpan.org/CPAN/authors/id/T/TI/TIMB/Devel-NYTProf-6.03.tar.gz
tar xvfz Devel-NYTProf-6.03.tar.gz
cd Devel-NYTProf-6.03/ && perl Makefile.PL
make && make install

Run xcat with nytprof

chtab  key=enableperf site.value=1  # make sure xcat daemon is running at this step
service xcatd stop
export NYTPROF=start=no
perl -dt:NYTProf /opt/xcat/sbin/xcatd -f

Test case Example

Fetch the project

git clone https://github.com/chenglch/xcatperf.git

Install the python dependency

apt-get install python-pip  python-dev
cd xcatperf
pip install -r requirements.txt

Disable the xcat service, then start and run test with the following command, which means running defls test case in 100 nodes environment with 3 concurrency value.

python bin/xcat-perf.py -p 3 -c 100 defls.DeflsCase

defls.DeflsCase is a scenario test plugin located in xcatperf/scenario. If we hope to generate nytperf results, try the following command

python bin/xcat-perf.py -p 3 -c 100 defls.DeflsCase --is-nytprof 1 --nytprof-dir /opt/nytprof/nytprof --http-url http://10.5.101.10:8086/

nodeset.NodesetCase is a test plugin to test nodeset performance

python bin/xcat-perf.py -p 1 -c 10 nodeset.NodesetCase --is-nytprof 1 --nytprof-dir /opt/nytprof/nytprof --http-url http://10.5.101.10:8086/

Note: nytprof option will generate too many files in target directory. More command options can be found using python bin/xcat-perf.py --help command.

Configure apache2 service for nytprf

cp etc/xcat-nytprof.conf.example /etc/apache2/sites-available/xcat-nytprof.conf
# edit xcat-nytprof.conf to meet your requiriment
cd /etc/apache2/sites-enabled && ln -s ../sites-available/xcat-nytprof.conf xcat-nytprof.conf
cd -

View the results

Open url http://10.5.101.10:8086/ to see the results for every process.
