Testing your GPU application with PyOpenCL
In this chapter, we comparatively tested the performance between a CPU and GPU. Before you begin the study of the performance of algorithms, it is important to keep in mind the platform of execution on which the tests were conducted. In fact, the specific characteristics of these systems interfere with the computational time and they represent an aspect of primary importance.
To perform the tests, we used the following machines
- GPU: GeForce GT 240
- CPU: Intel Core2 Duo 2.33 Ghz
- RAM: DDR2 4 Gb
How to do it…
In this test, the computation time of a simple mathematical operation, that is, the sum of two vectors with elements expressed in a floating point will be evaluated and compared. To make a comparison, the ...
