Gaussian Elimination

This program is a C implementation to improve performance of a Gaussian Elimination Code, using OpenMP, Pthreads and Pool of Threads

You can compile everything using the Makefile and run the objects created.

$ make

There is a script with alias for running the programs. You can type:

$ source script.sh

Then, type:

$ help

You will see all the alias to run the program. It should be run after make and should be with source. You should be able to see:

gauss - serial version
threads_gauss - pthread implementation
chunk_threads - pthread implementation with chunks
openmp - OpenMP implementation
pool_threads - Pool of threads implementation
chunk_pool_thread - Pool of threads implementation with chunks

Otherwise you can run, one by one using the following commands:

For compile and run the serial version. you can type:

$ gcc gauss.c -o gauss.out

$ ./gauss.out <matrix_dimensions> [random seed]

For compile and run the pthread implementation. you can type:

$ gcc threads_gauss.c -pthread -o threads.out

$ ./threads.out <matrix_dimensions> [random seed]

For compile and run the pthread implementation with chunks. you can type:

$ gcc chunk_threads_gauss.c -pthread -o chunkthreads.out

$ ./chunkthreads.out <matrix_dimensions> [number of threads] [random seed]

For compile and run the OpenMP implementation. you can type:

$ gcc openmp_gauss.c -fopenmp -o openmp.out

$ ./openmp.out <matrix_dimensions> [random seed]

For compile and run the Pool of threads implementation. you can type:

$ gcc thpool_gauss.c thpool.c -o pool.out

$ ./pool.out <matrix_dimensions> [number of threads] [random seed]

For compile and run the Pool of threads implementation with chunks. you can type:

$ gcc chunk_thpool_gauss.c thpool.c -o chunkpool.out

$ ./chunkpool.out <matrix_dimensions> [number of threads] [random seed]
