  The future of radio astronomy will require instruments with large collecting
areas for higher sensitivity, wide fields of view for faster survey speeds, and
efficient computing and data rates relative to current capabilities. We
describe the first successful deployment of the E-field Parallel Imaging
Correlator (EPIC) on the LWA station in Sevilleta, New Mexico, USA (LWA-SV).
EPIC is a solution to the computational problem of large interferometers. By
gridding and spatially Fourier transforming channelised electric fields from
the antennas in real-time, EPIC removes the explicit cross multiplication of
all pairs of antenna voltages to synthesize an aperture, reducing the
computational scaling from $\mathcal{O}(n_a^2)$ to $\mathcal{O}(n_g \log_2
n_g)$, where $n_a$ is the number of antennas and $n_g$ is the number of grid
points. Not only does this save computational costs for dense arrays but it
produces very high time resolution images in real time. The GPU-based
implementation uses existing LWA-SV hardware and the high performance streaming
framework, Bifrost. We examine the practical details of the EPIC deployment and
verify the imaging performance by detecting a meteor impact on the atmosphere
using continuous all-sky imaging at 50 ms time resolution.
