Pushing BitTorrent Locality to the Limit
Peer-to-peer (P2P) locality has recently raised a lot of interest in the community. Indeed, whereas P2P content distribution enables financial savings for the content providers, it dramatically increases the traffic on inter-ISP links. To solve this issue, the idea to keep a fraction of the P2P traffic local to each ISP was introduced a few years ago. Since then, P2P solutions exploiting locali...
متن کاملPushing NRQCD to the limit
Lattice NRQCD has proven successful in describing the physics of the upsilon system and B mesons, though some concerns arise when it is used in simulations of charm quarks. It is certainly possible that the NRQCD expansion is not converging fast enough at this scale. We present some preliminary results on the low-mass breakdown of NRQCD, in particular the behaviour of QQ̄ and Qq̄ spectra as the b...
متن کاملPushing Software Events to the Hardware Limit
Runtimes and applications that rely heavily on event notifications suffer when such notifications must traverse several layers of processing in software. Many of these layers necessarily exist in order to support a general-purpose, portable kernel architecture, but they introduce unacceptable overheads for demanding, high-performance parallel runtimes. Other overheads can arise out of a mismatc...
متن کاملOn the locality of BitTorrent-based video file swarming
In the past few years, there have been tremendous interest in the peer-to-peer(P2P) content delivery. Although this communication paradigm does not need a dedicated server infrastructure, it dramatically increases the traffic over inter-ISP links. In particular, the most popular P2P application, BitTorrent(BT) generates a huge amount of traffic on the Internet. To address this challenge, P2P lo...
متن کاملSvante Pääbo: pushing ancient DNA to the limit
Archaeology drew Svante Pääbo to science when he was a boy growing up in Sweden. But the university archaeology courses he took while still in high school in Uppsala were “too slow,” he says. So he matriculated in medicine and finally landed in one of the most technically demanding areas of laboratory biology: immunology. But he still secretly dug mummies. While a graduate student at the Univer...
