Abstract
Ongoing technological developments in Graphics Processing Units (GPUs) provide an opportunity for digital processing systems of unprecedented scale. For current and planned arrays with large numbers of receivers, GPU-accelerated correlator systems enable the real-time processing of large bandwidths. The Canadian Hydrogen Intensity Mapping Experiment
(CHIME) correlator provides an example of a fully-implemented GPU-based correlator X-Engine, with 1024 AMD Fiji GPU cores providing its substantial computational power. A GPU-based X-Engine for the Next Generation Very Large Array (ngVLA), incorporated into the SCalable REconfigurable And Modular (SCREAM) correlator design, may offer an alternative to the FPGA-based reference design.


Location:  Socorro DSOC Auditorium  (Broadcast to CV, GB)

Local Host:  N. Thyagarajan
