Enhance your preferences with the Throttle Tool
When running World Community Grid's agent for Windows, you will now see that 100% of the CPU is not used by default. World Community Grid has introduced a default setting of 60%. We've found that some recently designed computers deal with slight increases in CPU temperature (such as those caused by running at higher utilization) by slowing the CPU rather than speeding up the cooling fan as needed. This could cause a computer to run slower than usual. To keep this from happening, World Community Grid decided to reduce the grid agent's default CPU throttle setting so that the CPU does not heat up significantly. If you wish to change the CPU utilization setting, we provide a downloadable tool to do this. (This throttle feature is not yet available for the BOINC based agents.)

Chimpanzees living in dense jungles in Africa have been confirmed as the probable source of the HIV virus which caused the human AIDS pandemic.Researchers have identified simian immunodeficiency virus (SIV) in wild apes for the first time. The virus, which at some point jumped to humans as human immunodeficiency virus (HIV), has been found in chimpanzees in Cameroon, west-central Africa.The virus was found in chimpanzees in southeastern Cameroon, where SIV infection rates were as high as 35 percent in some chimp populations.Further genetic analysis linked these chimps to the source of the main strain of HIV-1, the most prevalent form of HIV. The team's findings are to be published tomorrow in the journal Science.The Cameroonian chimps showed a diversity of SIV strains, with some twice as similar to human HIV strains as any found in captive apes, says study team member Beatrice Hahn, a professor of medicine at the University of Alabama at Birmingham."Two clusters [of SIV strains] were very closely related to human strains," she added.These human strains belong to the M group of HIV-1, the group which has spread among humans worldwide.Hunters in the region who caught and ate chimps were probably the first to contract HIV, she adds.Chimps in turn are thought to have picked up SIV by eating infected monkeys.Chimps, however, are the only apes known to be infected."The chimp virus is a mosaic of viruses that infect prey monkeys," the University of Alabama's Hahn said. "Chimps had to eat these monkeys first but they have certainly had their infection a lot longer than humans.""As far as we know, the chimps don't get any type of AIDS-like disease," he said. "That's part of the reason for being very interested in the infection of chimps, because chimps and humans are very similar genetically."
