Building and Running MPI Code
Building an MPI Code All implementations provide wrappers around the underlying compilers that simplify compilation. As it is very important to use the headers that correspond to a given library, users are urged to make use of the wrappers whenever possible. For OpenMPI and MVAPICH2 these are:
mpicc (C) mpicxx (C++) mpif90 (Fortran free or fixed format) For Intel MPI these use gcc/g++/gfortran by default, which is generally not recommended; to use the Intel compilers the corresponding wrappers are:
mpiicc mpiicpc mpiifort Note: At this time, we recommend MPI users build with Intel 18.0 and IntelMPI 18.
Abinit and UVA HPC
Description ABINIT is a package whose main program allows one to find the total energy, charge density and electronic structure of systems made of electrons and nuclei (molecules and periodic solids) within Density Functional Theory (DFT), using pseudopotentials and a planewave or wavelet basis. Software Category: chem
For detailed information, visit the Abinit
website.
Available Versions The current installation of Abinit
incorporates the most popular packages. To find the available versions and learn how to load them, run:
module spider abinit The output of the command shows the available Abinit
module versions.
For detailed information about a particular Abinit
module, including how to load the module, run the module spider command with the module’s full version label.
Message Passing Interface (MPI) and UVA HPC
Overview MPI stands for Message Passing Interface. The MPI standard is defined by the Message Passing Interface Forum. The standard defines the interface for a set of functions that can be used to pass messages between processes on the same computer or on different computers. MPI can be used to program shared memory or distributed memory computers. There is a large number of implementations of MPI from various computer vendors and academic groups. MPI is supported on the HPC clusters.
MPI On the HPC System MPI is a standard that describes the behavior of a library. It is intended to be used with compiled languages (C/C++/Fortran).
