Parallel Programming using OpenMP and SIMD

Parallel Programming using OpenMP and SIMD

Problem Statement

Note : - Used Matplotlib , a 3rd party libary for plotting histograms. - No memory leaks in actual program[ I've verified] . However, since this 3rd paty has been included, it gives some memory leaks.

How to Run?

Part 1: High-dimensional Sphere

To see actual results in graph, try to plot more than 1000 points.

To compile

> make

This wll create two binaries. One of which represents generation of High Dimensional sphere in 'Sequential' way and another in 'Parallel' [ using openmp] way.

To run Sequential version:

> ./sequential_sphere <number_of_points>

To run Parallel versin:

> ./parallel_sphere <number_of_points>

For each version, separate 'graphs_xxx' is created which has 'Histograms' of all points. A third party library is used for this.

Part 2: SIMD(AVX specification) for computing lengths of a sequence of line segments.

Computing 24000000 segments and showing results on condole.

To compile:

> make

To Run:

> ./simd
