Intro to Performance optimisation

This package should be used by any programmer interested by tunning or monitoring the performance of his applications. This package contains the following tools:

• Kernel Generator: used to determine what are the different frequency used by your processor during different scenario (AVX1, AVX2, Turbo ON/OFF...)
• DML_MEM: a benchmark used to measure the performance of the memory subsystem by accessing memory with stride access
• YAMB: a tool used to monitor the memory bus traffic.
• Oprofile++: a tool to find and extract hot spots from an application

Install

Each tool/benchmark can be compiled separately. You can choose which one to compile by modifying the Cmake configuration file in src/CMakeLists.txt. For example, to only compile the Kernel Generator, you can use the following configuration:

add_subdirectory (benchmark_kernel_generator)
#add_subdirectory(tool_oprofile)
#add_subdirectory (tool_yamb)
#add_subdirectory (benchmark_dml_mem)

Here is the simplest way to download and install our tools:

git clone [email protected]:PourroyJean/performance_modelisation.git performance_modelisation
cd performance_modelisation
mkdir build
cd build
vi ../src/CMakeLists.txt  #to choose which tool to compile 
cmake ..
make

Configure each tool

Each tool can be compiled separately and have its own settings.

DML_MEM benchmark

The DML benchmark can be compiled with MPI or not. To do this, the following flag must be set in the cmake tool configuration:

cmake -DDML_BUILD_MPI=ON ..

To analyze the different steps of the benchmark (change of stride size, data set size) it can be interesting to monitor the memory bus traffic with YAMB and to annotate the graph with the library provided for. To do this, the following flag must be set in the cmake tool configuration:

cmake -DDML_USE_YAMB=ON ..

Requirement

• CMAKE - An open-source, cross-platform family of tools designed to build, test and package software

Other

We also provide :

• KeKKak: simple kernels is developped to have a fair comparison of microarchitectures on the Keccak algorithm
