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.

I am happy to announce that the user of the month for January 2013 is Ann Syrowski from University of Illinois at Urbana-Champaign. Ann is a Research Professional in the Atmospheric Science department's Convective Modeling Group. She develops numerical simulations of severe storms using the Weather Research and Forecasting (WRF) model and several HPCs throughout the country. Ann has moved more than 100 TB of data using Globus Online—50 TB in the past month alone—among a variety of HPC resources including XSEDE resources, NCSA's mass storage system, and PSC's data archiver.

It is my pleasure to announce that the user of the month for December 2012 is Kurt LaButti from the Department of Energy's Joint Genome Institute.

Kurt has been in the genomics industry since 2001. He started at what is now the Broad Institute of Harvard and MIT working on the human genome. He performed closure on chromosomes 17 and 11. He then transitioned into bioinformatics and assembly analysis, working primarily on fungi and virus genomes. At the Joint Genome Institute, he assembles and analyzes data from the DOE community, sequencing relevant organisms. His group handles microbes, metagenomes, fungi, and other interesting projects.

ESnet (Energy Sciences Network) has deployed three anonymous read-only GridFTP servers for testing purposes. These GridFTP servers are available as endpoints on Globus Online: esnet#anl-diskpt1, esnet#bnl-diskpt1 and esnet#lbl-diskpt1. Globus Online users can use these endpoints for testing purposes. Since these endpoints allow anonymous access, you do not need a username and password to access them. It should be noted that you can only read data from these endpoints and not write data to them.

Earlier this week at the SC12 conference we announced a set of new services that we plan to launch early in 2013, including a simple, fast way to share big data directly from your own storage (without moving it to a cloud storage provider). We also announced that some of these future services will have a monthly fee associated with them, in keeping with our objective to make Globus Online a self-sustaining effort. We've received positive feedback on our development plans, as well as many questions, and I'd like to further expand on our announcement.

Our mission is to serve the data management needs of researchers at academic and non-profit institutions. In order for us to do this effectively, we must be able to sustain our operations—a task that is not easy to do within the traditional research funding environment. Federal agencies continue to support our core research through grants, but these grants are not intended to fund operating costs for things like cloud hosting resources, user support staff, and helpdesk software, among others. Our goal is to charge a modest fee to those researchers and projects who receive substantial value from our service, not so that we can make money, but so that we can sustain Globus Online over the long term.

I am pleased to announce that the user of the month for October 2012 is Dmitry Ozerov from DESY in Germany.

Dmitry has a background in particle physics research and is currently working as an IT data management specialist in the Scientific Data Management and Grid Computing team at DESY, Hamburg. The team manages 7.5 petabytes of disk and 4 petabytes of tape storage, and the batch facility for the scientists from the High Energy Physics and Photon Science.
