1) Message boards : LHC@home Science : Gravitational Lens via Particle Accelerator (Message 24968) Posted 27 Nov 2012 by ocf81 Post: I don't know the physics involved, but my guess is that it in order to yield any usable gravitational effects it would have to be immensely powerful. My gut feeling say that you'd have to close to the speed of light to a ridiculously small margin. It would be nigh on impossible to make it economically viable to launch such a large device into space. You'd need way to much power to make it a reality, because of the necessary acceleration of the particles involved. As a microscope, perhaps. I don't know the quantum mechanics for it either.
2) Message boards : Number crunching : 25% overclock results in 35-45% faster run time? (Message 24884) Posted 6 Oct 2012 by ocf81 Post: maybe it was just some very short tasks, but yjr performance seems to be more in line with the overclock now.
3) Message boards : Number crunching : 25% overclock results in 35-45% faster run time? (Message 24883) Posted 5 Oct 2012 by ocf81 Post: I've noticed this curious thing. It seems that a 25% overclock results in a 35-45% faster run time of the WU's. Can someone explain to me why my second box, which as of today is back in action, is running the same kinds of tasks in just over half the time it takes my unoverclocked box to do them? Like the title says, the cpu is boosted from the standard i7 950 speed (3.07 GHz) to 3.86 GHz, or about 25%. (Works well as long as it's not too hot outside)
4) Questions and Answers : Sixtrack : problem with a long running WU. Bug or data problem? (Message 24686) Posted 22 Aug 2012 by ocf81 Post: I've cancelled the WU. The completion time wasn't dropping to an acceptable level. New LHC WU's are running with a normal projected completion time.
5) Questions and Answers : Sixtrack : problem with a long running WU. Bug or data problem? (Message 24684) Posted 22 Aug 2012 by ocf81 Post: I'm about to cancel a WU which has some really odd properties. It's a WU which is supposed to finish about 6 days from now, but has about a 100ish hours of running time left. This will no doubt fail the deadline as the computer is only on for about 12 - 15 hours per day. Normally this system will complete a sixtrack WU in about 7½ to 8 hours, so I suspect something is wrong. I'm about to cancel this work, but I'd like to notify you before I do. Could this be caused by a power outage I experienced yesterday? Is this a freak WU? Is there a way to check the WU's data integrity to check for damage? Here are the details (In dutch, I hope that this isn't a problem)
