Overview

Interface between MPI (the Message Passing Interface standard) and the Lua scripting language.

Example usage

local MPI = require 'MPI'
local buffer = require 'buffer'

local size = buffer.new_buffer(buffer.sizeof(buffer.int))
local rank = buffer.new_buffer(buffer.sizeof(buffer.int))

MPI.Init()
MPI.Comm_rank(MPI.COMM_WORLD, rank)
MPI.Comm_size(MPI.COMM_WORLD, size)

print(buffer.get_typed(rank, buffer.int, 0))
print(buffer.get_typed(size, buffer.int, 0))

MPI.Finalize()

Build instructions

Make sure you have the MPI sources installed.

Create a file called Makefile.in which contains macros like these:

CC = mpicc
LUA_HOME = /path/to/lua-5.2.1

# Additional compile flags are optional:

CFLAGS = -Wall -O2
LVER = lua-5.2.1 # can be lua-5.1 or other

Optionally, you may install local Lua sources by typing make lua.

Run make.
