# description: Run selected benchmarks after system startup.  The benchmarking software was acquired and installed as follows:
# -Sysbench https://github.com/akopytov/sysbench/archive/1.0.11.tar.gz
#			yum -y install make automake libtool pkgconfig libaio-devel mariadb-devel
# -C-ray	http://www.futuretech.blinkenlights.nl/depot/c-ray-1.1.tar.gz

# Calculate number of CPU cores for benchmarks
CORES=`/bin/lscpu | grep 'per socket' | awk '{print $4}'`
CPUS=`/bin/lscpu | grep -e '^CPU(s):' | awk '{print $2}'`
THREADS=`/bin/echo "$CORES * $CPUS" | /bin/bc -l`
echo "*** This machine has $CPUS CPU(s) and $CORES cores (benchmarks will utilize $THREADS threads)"
