In the stock markets, the so-called "January Effect" is the increase in stock prices during the month of January that commentators attribute to investors buying stocks after having sold them during the previous December (usually for tax reasons). Unlike most January's, last month the markets experienced a steep drop—the Dow Jones Industrial Average lost 5.3% from its 2013 year-end level. But I'm happy to say that the January Effect is alive and well at Globus!

I am pleased to honor Joel Brownstein from the University of Utah as the Globus User of the Month for December 2013. Professor Joel Brownstein is the data archivist of the Sloan Digital Sky Survey-IV (SDSS-IV), which is the continuation of the SDSS-I, -II, and -III surveys.

The SDSS-I, -II, and -III surveys have together amassed hundreds of terabytes of data from millions of stars throughout the Milky Way, and distant galaxies and quasars that allow us to study the structure and evolution of galaxies, the nature of dark energy and dark matter, and the cosmological history of the universe.

XSEDE just announced that Globus Connect Server (formerly called Globus Connect Multiuser) is now accepted for use in Campus Bridging. Campus Bridging efforts in XSEDE aim to lower the barriers for researchers that wish to utilize XSEDE resources and to define best practices for campus IT staff connecting to national cyberinfrastructure.

Chicago, Illinois - October 31, 2013 - Globus Online announces today the availability of Provider Plans that enable computing centers at non-profit institutions to deliver powerful and scalable data management capabilities to researchers, backed by enhanced levels of operational support.

The new Provider Plans will cater to the specific demands of HPC resource owners—such as campus research computing centers, scientific laboratories, and national supercomputing facilities—to further integrate Globus Online as a critical service for their users.

We had the pleasure of meeting this month’s honored users in person at the XSEDE13 Conference in San Diego last month. Brian Leu, Parth Sheth, and Albert Liu are all undergraduates at the University of Michigan. Brian answered my questions about how they use Globus Online to manage their undergraduate research data. We couldn't be happier that Globus Online has helped them continue their research over the summer--and that they've never known the difficulties of moving research data in the pre-Globus era!

Researchers who move data over the Internet with tools such as FTP on the TCP communication protocol to detect and retransmit data packets that have become corrupted in transit. It turns out that in doing so, they are leaning on an extremely weak reed. A 16-bit checksum means that 1 in 65,536 bad packets will be erroneously accepted as correct. You might think that corrupted packets are rare.

We just crossed the 10,000 mark for registered users and it made me think of the early days of Globus Online. Our first users were Shreyas Cholia, David Skinner, and others from NERSC, a very supportive group that helped us troubleshoot and refine pre-release versions of the file transfer service.

We just released Globus Connect Multiuser version 2. This is a major update over the previous version, featuring:

  • Native packaging: Native RPM and Debian packages for more than a dozen Linux variants.
  • Globus Toolkit integration: Globus Connect Multiuser is now a Globus Toolkit package, available from the standard Globus Toolkit repository, which leverages the other standard Globus Toolkit packages (e.g., GridFTP, MyProxy).
  • Easy update: Once you have installed Globus Connect Multiuser v2, updates can be installed simply via standard, native package updates from our repo. And because Globus Connect Multiuser depends on the normal Globus Toolkit packages, any updates to Globus Toolkit (e.g., a GridFTP fix or new feature) are now instantly available with Globus Connect Multiuser. (Note: If you have a existing installation of a previous version of Globus Connect Multiuser, you should delete it and do a fresh installation of v2.)

Did you miss GlobusWORLD? It was a great event, with a wide range of attendees, and three days of tutorials, presentations, networking--and some flooding in suburban Chicago for good measure. For a nice overview of the topics and issues examined in-depth at GlobusWORLD, check out this post by Rob Mitchum, which first appeared on the Computation Institute blog.

People who work in laboratories take a lot of things for granted. When they come into work in the morning, they expect the equipment to have power, the sink to produce hot and cold water, and the internet and e-mail to be functional. Because these routine services are taken care of “behind the scenes” by facilities and IT staff, scientists can get started right away on their research.

It is my pleasure to announce that we have selected Vadim Roytershteyn as the user of the month for May 2013.

Vadim is a plasma physicist at SciberQuest, Inc., where he uses large-scale simulations to study a variety of processes in laboratory, space, and astrophysical plasmas. He primarily works with so-called fully kinetic simulations, which use computational particles to represent plasma species (such as electrons and ions). Such simulations are very attractive because they provide essentially first-principle description of plasma under fairly general conditions. At the same time, fully kinetic simulations generate a very large amount of data, which can be challenging to deal with.
