What is iSGTW

iSGTW is an international weekly online publication that covers distributed computing and the research it enables.

We report on all aspects of distributed computing technology, such as grids and clouds. We also regularly feature articles on distributed computing-enabled research in a large variety of disciplines, including physics, biology, sociology, earth sciences, archaeology, medicine, disaster management, crime, and art. (Note that we do not cover stories that are purely about commercial technology.)

In its current incarnation, iSGTW is also an online destination where you can host a profile and blog, and find and disseminate announcements and information about events, deadlines, and jobs. In the near future it will also be a place where you can network with colleagues.

You can read iSGTW via our homepage, RSS, or email. For the complete iSGTW experience, sign up for an account or log in with OpenID and manage your email subscription from your account preferences. If you do not wish to access the website's features, you can just subscribe to the weekly email here.

Our History

iSGTW began as Science Grid This Week, which was first published in April 2005. It went international on 16 November 2006, becoming International Science Grid This Week. Since then it has grown steadily, receiving over 165,000 unique visits in 2012, from countries all over the globe.  By email alone, iSGTW now has approximately 8,800 subscribers.

In the past, iSGTW reported exclusively on developments in grid computing technology and the scientific research it enabled. Grid remains our stock-in-trade, but we increasingly report on developments in other distributed computing fields — such as cloud technology — along with the occasional article about high performance computing (HPC, sometimes called “supercomputing”).

Our affiliated partners

iSGTW is jointly funded by organizations in America and Europe. In the US, it is funded  through the National Science Foundation. In Europe, it is funded by the European Commission’s Information Society and Media Directorate-General, through e-ScienceTalk. is a foundation established under Dutch law to create and maintain a pan-European Grid Infrastructure in collaboration with National Grid Initiatives and European International Research Organisations, to guarantee the long-term availability of a generic e-infrastructure for all European research communities and their international collaborators.
 The Open Science Grid enables scientific research by bringing multidisciplinary collaborations together with the latest advances in distributed computing technologies. The OSG, a U.S. grid computing project with international partners, is used for scientific research in many fields, including bioinformatics, nanotechnology and physics.
GridPP manages and operates the UK particle physics grid, which is the UK's contribution to the LCG. It is a collaboration of 20 universities and research institutes, funded by the Science and Technology Facilities Council.
XSEDEthe Extreme Science and Engineering Discovery Environment is the most advanced, powerful, and robust collection of integrated advanced digital resources and services in the world. It is a single virtual system that scientists can use to interactively share computing resources, data, and expertise.
E-ScienceTalk brings the success stories of Europe’s e-infrastructure to a wider audience. The project coordinates the dissemination outputs of the European Grid Infrastructure and other European e-Infrastructure projects, ensuring their results and influence are reported in print and online.
