DIII-D Researchers Use Machine Learning to Steer Fusion Plasmas

Researchers at the DIII-D National Fusion Facility achieved a scientific first this month when they used machine learning calculations to automatically prevent fusion plasma disruptions in real time, while simultaneously optimizing the plasma for peak performance. The new experiments are the first of what they expect to be a wave of research in which machine learning–augmented controls could broaden the understanding of fusion plasmas. The work may also help deliver reliable, peak performance operation of future fusion reactors.

Advancing Fusion Science with CGYRO using GPU-based Leadership Systems

Jeff Candy and Igor Sfiligoi from General Atomics gave this talk at the GPU Technology Conference. “Gyrokinetic simulations are one of the most useful tools for understanding fusion science. We’ll explain how we designed and implemented CGYRO to make good use of the tens of thousands of GPUs on such systems, which provide simulations that bring us closer to fusion as an abundant clean energy source. We’ll also share benchmarking results of both CPU- and GPU-Based systems.”

General Atomics Fabricates First ITER Central Solenoid Module for Nuclear Fusion

Engineers at General Atomics have completed fabrication of the first ITER Central Solenoid Module for nuclear fusion. When the ITER fusion energy project in France powers up in 2025, its first operations will be enabled by the largest pulsed superconducting magnet ever built – a magnet that has roots in Southern California.

Job of the Week: Software Developer for Exascale at General Atomics

General Atomics in San Diego is seeking a Software Developer for Exascale Computing at General Atomics in our Job of the Week. “This position independently leads the design, development and verification of novel scientific software for high-fidelity physics simulations on unique high performance computational hardware including Exascale-class systems.”

General Atomics Releases Next-Gen Nirvana Data Management Software

Today General Atomics announced the next generation of Nirvana – a premier metadata, data placement and data management software solution for the most demanding workflows in Life Sciences, Scientific Research, Media & Entertainment and Energy Exploration. “Nirvana 5.0 reduces storage costs up to 75% by turning geographically dispersed, multiple vendor storage silos into a single global namespace that automatically moves infrequently-accessed data to lower-cost storage or to the cloud.”

Video: General Atomics Delivers Data-Aware Cloud Storage Gateway with ArcaStream

“Ngenea’s blazingly-fast on-premises storage stores frequently accessed active data on the industry’s leading high performance file system, IBM Spectrum Scale (GPFS). Less frequently accessed data, including backup, archival data and data targeted to be shared globally, is directed to cloud storage based on predefined policies such as age, time of last access, frequency of access, project, subject, study or data source. Ngenea can direct data to specific cloud storage regions around the world to facilitate remote low latency data access and empower global collaboration.”

World’s First Data-Aware Cloud Storage Gateway Coming to SC15

Today ArcaStream and General Atomics introduced Ngenea, the world’s first data-aware cloud storage gateway. Ready for quick deployment, Ngenea seamlessly integrates with popular cloud and object storage providers such as Amazon S3, Google GCS, Scality, Cleversafe and Swift and is optimized for data-intensive workflows in life science, education, research, and oil and gas exploration.
