Video: Characterizing Network Paths in and out of the Clouds

Igor Sfiligoi from SDSC gave this talk at CHEP 2019. “Cloud computing is becoming mainstream, with funding agencies moving beyond prototyping and starting to fund production campaigns, too. An important aspect of any production computing campaign is data movement, both incoming and outgoing. And while the performance and cost of VMs is relatively well understood, the network performance and cost is not.”

SDSC Conducts 50,000+ GPU Cloudburst Experiment with Wisconsin IceCube Particle Astrophysics Center

In all, some 51,500 GPU processors were used during the approximately two-hour experiment conducted on November 16 and funded under a National Science Foundation EAGER grant. The experiment used simulations from the IceCube Neutrino Observatory, an array of some 5,160 optical sensors deep within a cubic kilometer of ice at the South Pole. In 2017, researchers at the NSF-funded observatory found the first evidence of a source of high-energy cosmic neutrinos – subatomic particles that can emerge from their sources and pass through the universe unscathed, traveling for billions of light years to Earth from some of the most extreme environments in the universe.

PSI Researchers Using Comet Supercomputer for Flu Forecasting Models

Researchers at Predictive Science, Inc. are using the the Comet Supercomputer at SDSC for Flu Forecasting Models. “These calculations fall under the category of ‘embarrassingly parallel’, which means we can run each model, for each week and each season on a single core,” explained Ben-Nun. “We received a lot of support and help when we installed our codes on Comet and in writing the scripts that launched hundreds of calculations at once – our retrospective studies of past influenza seasons would not have been possible without access to a supercomputer like Comet.”

Supercomputing the Future Path of Wlldfires

In this KPBS video, firefighters in the field tap an SDSC supercomputer to battle wild fires. Fire officials started using the supercomputer’s WIFIRE tool in September. WIFIRE is a sophisticated fire modeling software that uses real-time data to run rapid simulations of a fire’s progress. It helps to see where the fire is likely going to go,” said Raymond De Callafon, a UCSD engineer who worked on the project. “So, a fire department can use this for planning purposes with their limited resources. It can also be used to plan, maybe their aircraft that will go over. Where to put the fire out.”

SDSC Awarded NSF Grant for Triton Stratus

The National Science Foundation has awarded SDSC a two-year grant worth almost $400,000 to deploy a new system called Triton Stratus. “Triton Stratus will provide researchers with improved facilities for utilizing emerging computing paradigms and tools, namely interactive and portal-based computing, and scaling them to commercial cloud computing resources. Researchers, especially data scientists, are increasingly using toolssuch as Jupyter notebooks and RStudio to implement computational and data analysis functions and workflows.”

NSF Funds $10 Million for ‘Expanse’ Supercomputer at SDSC

SDSC has been awarded a five-year grant from the NSF valued at $10 million to deploy Expanse, a new supercomputer designed to advance research that is increasingly dependent upon heterogeneous and distributed resources. “As a standalone system, Expanse represents a substantial increase in the performance and throughput compared to our highly successful, NSF-funded Comet supercomputer. But with innovations in cloud integration and composable systems, as well as continued support for science gateways and distributed computing via the Open Science Grid, Expanse will allow researchers to push the boundaries of computing and answer questions previously not possible.”

Michael Zentner to Lead SDSC Sustainable Scientific Software Group

Today the San Diego Supercomputer Center (SDSC) announced the appointment of Michael Zentner as director of Sustainable Scientific Software, effective immediately. “Having worked with Michael as a co-PI of SGCI since 2016, I’m confident that he has the skills needed to move the institute forward as PI,” said Wilkins-Diehr. “I’m thrilled that Michael has accepted this position with SDSC, and am excited about the expanded role he’ll play as the Center sharpens its focus on software sustainability.”

Video: Supercomputing Dynamic Earthquake Ruptures

Researchers are using XSEDE supercomputers to model multi-fault earthquakes in the Brawley fault zone, which links the San Andreas and Imperial faults in Southern California. Their work could predict the behavior of earthquakes that could potentially affect millions of people’s lives and property. “Basically, we generate a virtual world where we create different types of earthquakes. That helps us understand how earthquakes in the real world are happening.”

Call for Presentations: MVAPICH User Group in August

The 7th annual MVAPICH User Group (MUG) meeting has issued its Call for Presentations. MUG will take place from August 19-21, 2019 in Columbus, Ohio. “MUG aims to bring together MVAPICH2 users, researchers, developers, and system administrators to share their experience and knowledge and learn from each other. The event includes keynote talks, invited tutorials, invited talks, contributed presentations, open MIC session, hands-on sessions with MVAPICH developers, etc.”

Sylabs boosts HPC Containers with SingularityPRO 3.1

Today Sylabs announced the release of SingularityPRO 3.1 in what the company is calling a watershed moment for enterprise customers everywhere. “SingularityPRO 3.1 is the most highly anticipated release of our enterprise software ever,” said Gregory Kurtzer, founder and CEO of Sylabs. “With this release, we’re rapidly advancing container science, making it a truly opportune time for those seeking to containerize the most demanding enterprise performance computing workloads in the most trusted way.”
