Many Task Computing: Bridging the performance-throughput gap 

Ioan Raicu and Ian Foster of the University of Chicago, and Yong Zhao of Microsoft Corporation offer their thoughts on how grid computing can adapt to the "big data, many tasks" applications.

Tightly-coupled applications for which jobs must communicate between each other during execution are typically best served by clustered High Performance Computing. Applications with many independent job streams, on the other hand, are better suited to distributed High Throughput Computing. But there are still other kinds of applications.

Over the past half decade we’ve examined many applications from astrophysics, bioinformatics, data mining and other fields, and have found that high-performance computations comprising multiple distinct activities and coupled via file system operations (as opposed to the standard message passing interface commonly found in HPC) don’t fit nicely in either category. To address this, we’ve defined the concept of “Many Task Computing”.

Feature - gRAVI from Globus 

Packaging an application as a shareable grid service that other users can access remotely through a browser is quite a daunting task for most researchers. For the "other users," finding a shared grid service that will help advance their research is also a challenge.

This is where gRAVI (grid Remote Application Virtualization Interface) comes in.

Quotes of the week

/"We will wield technology's wonders..."

As U.S. president Obama was sworn into office on 20 January, he offered encouraging words to the scientific community:

"We'll restore science to its rightful place, and wield technology's wonders to raise health care's quality and lower its cost.  We will harness the sun and the winds and the soil to fuel our cars and run our factories."
