DESCRIPTION:The Murchison Widefield Array (MWA) can offer a unique insight 
 into the population of low-frequency radio transients in the southern sky 
 due to its wide field of view and unique high-time resolution voltage capt
 ure capabilities. The petabyte-sized MWA archive contains raw-voltage obse
 rvations spanning more than 7 years that can be scoured for objects evolvi
 ng over time. However\, the lack of tools to address the associated comput
 ational challenge impairs its potential for systematic discoveries. In thi
 s talk I will present the Breakthrough Low-latency Imaging with Next-gener
 ation Kernels (BLINK)\, a high time resolution imaging pipeline. It is a n
 ew software designed and developed from the ground up to run image-based f
 ast transient searches at petaFLOPS or even exaFLOPS scale on modern super
 computing infrastructure. It also features a new image-based dedispersion 
 algorithm called Streaming high-Time Resolution Imaging DEdispersion (STRI
 DE). This imaging pipeline achieves a 3700x speedup compared to a one base
 d on WSClean\, while the new dedispersion algorithm\, STRIDE\, reduces mem
 ory requirements by more than 97% in a typical wide-field search scenario.
  The software has been deployed on Pawsey's Setonix supercomputer to searc
 h for Fast Radio Bursts (FRBs) in the SMART dataset\, a process that analy
 sed 4 PB of voltage data\, generating 21 PB of intermediate images\, over 
 the course of 6 months. I will present early technical and science results
  of the search\, demonstrating petaFLOPS and petabytes scale computing is 
 possible today.
