Raytracing on Xeon Phi

This page is a collection of all articles about my research about raytracing applications on the Xeon Phi Coprocessor. I give a short summary about the content of my posts about that topic.

Part I: http://www.theismus.de/HPCBlog/?p=17
First attemp to use Xeon Phi compute power with a freeware raytracer in Xeon Phi’s native execution mode.


Part II: http://www.theismus.de/HPCBlog/?p=32
Here I’m using the same raytracer in native mode and try to find the peformance issue with the help of the Intel Vtune Amplifier and a scaling analysis.

Part III: http://www.theismus.de/HPCBlog/?p=59
For the last time the freeware raytracer is under investigation. This time in offload mode.



Part IV: http://www.theismus.de/HPCBlog/?p=87
Here the program under test is switched to a raytracer in Geometric Algebra (GA) which was developped during my master thesis. In this part I’m testing the OpenCL kernels of my raytracer on Xeon Phi and our server Xeons.


Part V: http://www.theismus.de/HPCBlog/?p=106
In this part my GA raytracer is rewritten in a C version based on the OpenCL kernel files and tested in offload mode.

  1. Heya i am for the first time here. I found this board and I in finding It ralley useful & it helped me out much. I hope to provide something back and help others such as you aided me.
