Accelerated Computing: "Experiences with a Performance Comparison of a Simple RTM Kernel on Xeon Phi," James Brodman, Intel

Watch the video recording

 

Accelerators are now a common tool for increasing the computing power of a machine. Xeon Phi is a new accelerator that combines the compute power of a GPGPU accelerator with the programmability of a multicore processor. Expert programmers can wring all the performance that this class of device can offer by meticulously performing low level optimizations. This talk presents experiences obtained from an exercise at the other end of the spectrum. A simple, unoptimized isotropic, 8th-order-in-space 3D RTM kernel that performs wave propagation without boundary conditions was chosen as the test vehicle to examine what performance can be achieved on Xeon Phi applying only three basic high-level optimizations.
