RCS Matlab Example Codes

This directory includes an example Matlab program to compute the Mandelbrot set on GPU. A CUDA C++ function is called by a Matlab code.

Description of files:

• mandelbrot_set.cu : a CUDA C++ function to compute the Mandelbrot set.
• main.m: a Matlab code to call the CUDA C++ function in mandelbrot_set.cu.
• job.script: a script to submit a batch job for this Matlab program.

Usage:

First, compile the CUDA C++ code,

module load cuda/9.1

nvcc -ptx mandelbrot_set.cu

An assembly-level ptx file is created.

Then open Matlab,

module load matlab/2018a

matlab &

and run the program in Matlab interface,

>> main

The computing times are compared on CPU and on GPU, and the figures of Mandelbrot set are plotted.

To run the Matlab program in background, submit a batch job,

qsub job.script
