Submission + - Princeton Researchers Announce Open Source 25-core Chip (princeton.edu) 1

Submitted by Anonymous Coward
An anonymous reader writes: Researchers at Princeton announced at Hot Chips this week their 25-core Piton Processor (http://www.princeton.edu/main/news/archive/S47/19/67G69/?section=topstories). The processor was designed specifically to increase data center efficiency with novel architecture features enabling over 8,000 of these processors to be connected together to build a system with over 200,000 cores. Fabricated on IBM’s 32nm process and with over 460 Million transistors, Piton is one of the largest and most complex academic processors every built. The Princeton team has opened their design up and released all of the chip source code, tests, and infrastructure as open source in the OpenPiton (http://www.openpiton.org) project enabling others to build scalable manycore processors with potentially thousands of cores.

Submission + - G-Spot 'doesn't appear to exist' (bbc.co.uk) 1

Submitted by krou
krou writes: The BBC reports that, according to a new study in the Journal of Sexual Medicine, a team from King's College London has found no evidence to suggest that the G-Spot actually exists, and they believe it may be a myth 'encouraged by magazines and sex therapists.' The study involved 1,800 women, all of whom were either identical or non-identical twins. Each were asked whether they had a G-Spot, the idea being that identical twins would both report having one. However, 'this pattern did not emerge and the identical twins were no more likely to share a G-spot than non-identical twins'. Co-author of the study Professor Tim Spector said: 'Women may argue that having a G-spot is due to diet or exercise, but in fact it is virtually impossible to find real traits. This is by far the biggest study ever carried out and shows fairly conclusively that the idea of a G-spot is subjective.' Sexologist Beverley Whipple, who popularised the term G-Spot, claimed the study was flawed, because 'the researchers had discounted the experiences of lesbian or bisexual women and failed to consider the effects of having different sexual partners with different love-making techniques.'
