Controlling the Tide of Weather and Climate Data with Tiered Storage


There’s an old cliché that everyone talks about the weather, but no one does anything about it. While Cray can’t (yet) prevent droughts or cool off hot spells, we can help make the lives of weather professionals easier. An abundance of data riches, but where to store it? Weather and climate modeling centers strive to improve the accuracy of their models by gathering and assimilating more diverse input data and by increasing model resolution and complexity. As a result, these models are ingesting and producing ever-increasing volumes of data. These weather and climate organizations often find themselves challenged by the sheer volume of data, trying to manage various ways it may be used and simply trying to find the resources, ...

Deepening Cray’s Involvement in Collaborative R&D and Codesign


Cray recently announced the birth of our new computing research organization for Europe, the Middle East and Africa (EMEA), the Cray EMEA Research Lab (CERL). Our investment in Europe is not new (the Cray®-1 and every machine since found a European home), but an explicit focus on research is a big and bold move for our company. I am very honored to be leading that change, and I will explain here what you can expect to see from CERL. Recent collaborations in EMEA For our current customers, this move is very welcome, but may not have been a huge surprise. That’s because during the last five years we have become more involved in deep research collaborations in EMEA. Most notably, Centers of Excellence at EPCC, HLRS and recently also at ...

Algorithmic Trading: Faster Execution or Smarter Strategies?


The short answer is: You need both. Since the advent of the first high-frequency trading (HFT) firm, the quest for low-latency trading has been paramount. Strategies that were profitable before HFT are now obsolete. Among those strategies with questionable profitability today are: Arbitrage: Markets move too quickly to allow time for arbitrage. Market making: HFT imposes excessive risks on those traders. Event trading: Competing against HFT in terms of speed of response to scheduled economic reports and conventional news is impossible, since HFT systems can process and react to the information quicker. Faster execution is necessary to take advantage of short-term opportunities. Profitability is directly correlated to volume ... [ Read More ]

OpenSFS and Cray Offer a New-Member Discount


Cray has been involved with Lustre® since its deployment with the groundbreaking Cray supercomputer “Red Storm,” at Sandia National Laboratories. Since then, a lot has happened throughout the Lustre community. One of the major milestones was the formation of the Open Scalable File Systems (OpenSFS) consortium in 2010. As a founding member of OpenSFS, Cray is committed to its success — and to the future of Lustre. OpenSFS is the source for technical information on Lustre and the Lustre user community. OpenSFS is the key vendor-neutral organization whose simple charter is to move Lustre forward.  OpenSFS has been responsible for advancing Lustre through both feature enhancements in new releases and through exhaustive, real-world testing, ...

Accelerate Your I/O with Cray DataWarp – A look back at what Cray did in the 80s

Cray XMP

Cray recently introduced the DataWarp™ applications I/O accelerator. The National Nuclear Security Administration will deploy this technology at a large scale in the “Trinity” system next year. This is a remarkable trend in the market, and for Cray it is reinvention of a technology that was deployed 30 years ago. Cray introduced the technology in its supercomputers in the early 1980s. The company offered solid-state storage devices (SSDs) for temporary storage of datasets as an extension to the Cray X-MP, Cray-1 S and Cray-1M systems to significantly increase data transfer rate. This “burst rate” was dependent upon SSD memory size and configuration. The SSD was housed in a stand-alone four-column chassis. All power supplies and cooling ... [ Read More ]
