MuGiq

An interface to perform MultiGrid deflation in nVIDIA GPUs using the QUDA library, for the efficient computation of disconnected diagrams and other measurements related to Lattice QCD applications.

External dependencies

This interface depends on:

• The QUDA (https://github.com/lattice/quda) library
• The PRIMME (https://github.com/primme/primme) library, which in turn depends on the MAGMA library
• MPI or QMP/QIO
• The parallel HDF5 library
• The CUDA toolkit

Installation

This package uses CMake for the installation process. It is recommended to install MuGiq in a separate directory from the source directory. Below are the steps for installing MuGiq using CMake:

• Create an install directory separate from the MuGiq source directory.
• cd <path-to-install-dir>
• Perhaps the most convenient way to configure installation options is to run ccmake <path-to-MuGiq-src> in order to set the options in an interactive manner.
• Alternatively one can run cmake <path-to-MuGiq-src> -D<option1>=value -D<option2>=value ... instead.
• run make -j<N> to install the package using N parallel jobs.
