For anyone who doesn't receive the newsletter, it looks as if Phase 2 of the Discovering Dengue project will be distributing some fairly lengthy work units, so just a heads-up for you.
World Community Grid is pleased to launch the Discover Dengue Drugs - Together - Phase 2 project by The University of Texas Medical Branch (UTMB) in Galveston, Texas, USA and the University of Chicago in Illinois, USA. The mission of Discovering Dengue Drugs – Together - Phase 2 is to identify promising drug leads to combat dengue, hepatitis C, West Nile, Yellow fever, and related viruses.

The extensive computing power of World Community Grid will be used to complete the structure-based drug discovery calculations required to identify these leads. For additional information on this project, please press the Research button in the upper navigation bar or click here.

Phase 2 of the Discovering Dengue Drugs – Together project involves a waterfall approach to creating work units. The first work units that members will receive are called Type A’s and the output from these will spawn Type B work units, which in turn will spawn type C work units. The researchers at UTMB will create Type B’s from the Type A results and Type C’s from the Type B results. This approach was done because otherwise, members would have to repeatedly run the many hours of computation each time to get to the point of running the type C work units. Also, it is not practical for the researchers to pre-compute all of this data without using the grid. You should know that at the start of the project there will be only 1,000 Type A work units and that all Type A work units will run somewhere between 50 to 100 hours. You should also know that there may be times when there are no work units available. This may occur when the UTMB researchers are creating successive work units.

Wow !! 50 to 100 hours, that's a long time.

Not good on a slow machine - the completion date may pass before the task is finished. ;)
