CHIUW 2017: Surveying the Chapel Landscape

CHIUW 2017 — the 4th Annual Chapel Implementers and Users Workshop — was held last month in Orlando, Fla., in conjunction with IEEE IPDPS 2017. Right out of the gate, attendees heard about a number of positive trends in the annual “state of the project” talk which summarizes Chapel progress over the past year. This year’s highlights included: Chapel performance is competitive with hand-coded C+OpenMP for single-node workloads as demonstrated by benchmarks like the Livermore Compiler Analysis Loop Suite (LCALS). For key communication benchmarks like ISx and HPCC RA, Chapel performance is increasingly competitive with the MPI/SHMEM reference versions, and occasionally beats them (see Figure 1 below). In May, Chapel became the ... [ Read More ]

AI Meets HPC at ISC 2017

Running astrophysics applications with 200,000 MPI tasks … diagnosing and treating autism spectrum disorders … researching the secure nature of the Advanced Encryption Standard algorithm. Those are among the many research dreams that HPC professionals talked about at the Cray booth at ISC High Performance 2017 in Frankfurt, Germany last week. Cray’s mission is to help customers realize their most challenging data science and research goals, and at ISC we took the next step with the introduction of the Cray® Urika®-XC analytics software suite, which embodies the convergence of supercomputing and analytics. With the new Urika-XC software suite, users can now run analytics, graph and AI workloads simultaneously on the same system, ... [ Read More ]

Bio-IT World 2017: Life Sciences Embrace Cloud

Hope you had a chance to attend the 16th annual, three-day Boston Bio-IT World Conference & Expo this year. Competitions included: Best Practices awards announcements and the Benjamin Franklin Award, and the show planners named the 2017 Best of Show winners. Tracks for the conference included: data and storage management, cloud computing, networking hardware, bioinformatics, next-gen sequencing informatics, data security and more. Face to face As many times as I’ve walked Bio-IT’s exhibit hall floor, the excitement of seeing in person someone I’ve been interacting with via email and phone – in some cases for years – and hearing their thoughts still pumps me up. True, social media has diminished the impact of conferences, but the ... [ Read More ]

Data Analytics Rule at Spark Summit West 2017

Spark Summit West is always well attended, and this year was no exception. Data engineers, data scientists, programmers, architects and technology enthusiasts descended on San Francisco’s Moscone Center earlier this month to learn all about the latest developments with Apache Spark™ and its massive ecosystem. Complexity of analytics use cases and data science was a dominant theme throughout this year’s event. The keynote by the CEO and co-founder of Databricks, Ali Ghodsi, highlighted some of the challenges with implementing large-scale analytics projects. Ghodsi discussed how the continued growth of Apache Spark has resulted in myriad innovative uses cases, from churn analytics to genome sequencing. These applications are difficult to ...

Cray Users from Around the World Meet at CUG 2017

Across Lake Washington from Cray’s downtown Seattle headquarters is the small city of Redmond, Wash. Redmond is best known as the home of Microsoft. But last week, it was the location for this year’s Cray User Group (CUG) conference. The Cray User Group is an independent, international corporation of member organizations that own Cray Inc. computer systems. The annual CUG conference brings together users from around the world to share several days of tutorials, technical sessions and networking. I serve on the CUG board of directors as the Cray advisor, a role I’ve enjoyed for more than 10 years. New to the program this year was an analytics track, which included a panel discussion titled “Future Directions of Data Analytics and ... [ Read More ]
