Compiling & Executing MP without the Run Script

This page describes how to build and run your MP without the run script.

Building

The Makefile is a symbolic link to dev/etc/mp.mak. It assumes that you execute it from the directory containing mp.cu. Compiling your MP directly would need to look something like the following:

cd mp/1
make

Running

The usage for the MP binary can be seen by running with no arguments:

usage: ./mp data/i

example: ./mp data/2

The only argument is a directory containing the MP input/output files. For example:

[~/cuda-edu/mp/1]$ ls data/0
input0.raw  input1.raw  output.raw

Setting Number of OS Threads

The number of OS threads is controlled by the environment variable EDU_CUDA_THREAD_COUNT. So, for example, if you wanted to run with a single thread, you would execute:

export EDU_CUDA_THREAD_COUNT=1
./mp data/0
