This repository provides a set of tools and libraries to profile Alltoallv MPI calls without having to modify applications. Profiling is performed in two phases:
make libraries
;
to compile the post-mortem analysis tools, execute make tool
.After cloning the repository, it is required to initialization the Git submodules:
git submodule update --init --recursive
It is adviced to compile the profiling tool with the same compilers than the ones used to compile the application, including MPI.
To compile the entire code base, it is recommended to execute the following command:
make all
More documentation about the MPI collective profiler itself, the one being used while profiling your application is available in src/README.md.
We provide a set of tools that parses and analyses the data compiled when executing
the application with our shared library. These tools are implemented in Go and all of
them except one (analyzebacktrace
) can be executed on a different platform.
