If you want to tweak your tests, you can change default configuration of MkFlags.ДЇirst you need to execute the following commands: MkFlagsДefault content of the MkFlags is: #Compiler You can continue to play with various gcc options.

Gnuplot> plot for 'results.dat' using (column(i+1)):xtic(1) title 'TEST '.iДЄnd here is result of my test in graphical format: Test results Gnuplot> set style fill solid border rgb 'black' Gnuplot> set style histogram cluster gap 1 Immediate help: type 'help' (plot window: hit 'h') Thomas Williams, Colin Kelley and many others The next step is to produce some graph to check the results visually: N U P L O TД¬opyright (C) 1986-1993, 1998, 2004, 2007-2017 sombrero.sh -n 2 -s small | awk 'BEGIN ' > test_results.dat You can also produce formatted output by using awk utility. In this case, correct number of cores is four. Result IвЂ™ve got needs to be divided by 2 to get the number of cores due to the hyper threading which assumes 2 threads per core on ењ†4 processors (Intel, on RISC there can be 4 or even more threads per core). You need to know number of cores of your server/cluster.Д«elow is one of many ways to find real number of cores: /proc/cpuinfo | grep processor | wc -l You can play with your PC by performing test with more cores like in the following example: -n 2 small n 1 smallДЄs a result youвЂ™ll get number of operations per second like the following: Once the installation completes, everything is ready to start with tests.ДЇor the first run I suggest to use just one CPU core and set a size of the test to small.

LetвЂ™s start with installation procedure: sudo apt install git make gcc bc gnuplot openssh-server openmpi-bin openmpi-common There is one mistake in installation instructions which is why IвЂ™m providing here correct way that works on Ubuntu (RedHat clones have slightly different commands which you can find on the Web).

You can use it in your local cluster, Cloud cluster, Oracle RAC (Real Application Cluster) as itвЂ™s very flexible and easy to use.ДЄlthough you can find more about how to install Sombrero at the following link: Sombrero is particularly useful for testing a mix of computation power, RAM speed and cluster interconnect network. In this article IвЂ™m going to use Somberero вЂ“ High Performance Computing tool suitable to run a test against your home PC or cluster of supercomputers. There are many benchmark testing tools that are focusing on various fields of a cluster like computing capabilities, energy efficiency, data & storage, memory etc.
