among different discretization approaches, finite difference method (fdm) is widely used for acoustic and elastic full-wave form modeling. an inevitable deficit of the technique, however, is its sever requirement to computational resources. a promising solution is parallelization, where the problem is broken into several segments, and the calculations are distributed over different processors. ...

We present an implementation of a channelizer (F-engine) running on Graphics Processing Unit (GPU). While not the first GPU channelizer, we have put significant effort into optimizing implementation. are able to process four antennas each with 2 Gsample/s, 10-bit dual-polarized input and 8-bit output, single commodity GPU. This fully utilizes available PCIe bandwidth The system is as optimized ...
