San Jose, California — Bright Computing, the leading provider of vendor-independent cluster and cloud management software, announces that Product Marketing Manager Ian Lumb will be presenting “Reverse Time Migration via Resilient Distributed Datasets: Towards In-Memory Coherence of Seismic-Reflection Wavefields using Apache Spark,” at the upcoming HPCS 2015, being held in Montreal from June 17-19, 2015. The presentation will take place Friday, June 19th at 11:20 a.m. in Room H-535.
Mr. Lumb’s presentation will focus on how seismic wavefields can be distributed in memory across a cluster using Apache Spark. This is an exciting new development that shows promise in addressing the computational challenge facing the petroleum exploration industry when using Reverse Time Seismic Migration (RTM) to determine the coherence between forward and time-reversed wavefields during the processing of seismic reflection data. Processing seismic reflection data with RTM is the most-accurate way to show all reflectors in their actual locations in space and time, and is crucial to effective oil and gas exploration.
Mr. Lumb will discuss how RDDs (Resilient Distributed Datasets), a relatively recent abstraction for in-memory computing ideally suited to distributed computing environments like clusters through the open-source implementation of Apache Spark, appear promising for improving RTM. He will specifically discuss how RDDs facilitate the assessment of coherence between seismic reflection wavefields in memory. Mr. Lumb will also outline an algorithm based on RDDs that significantly reduces the impact of disk I/O in the wavefield manipulations required by RTM. The algorithm has been implementation-prototyped using Apache Spark.
