Off topic: my house got hit directly by lightning a night ago. Luckily I have a lightning rod but the energy still goes into the ground and feeds back up through the phone line even though the DSL has a surge protector inline. Took out the DSL modem (fried), the switch the modem was on (5 ports good, 3 bad), one of the motherboards on a machine connected to that switch, maybe 1 GPU on a different box too. Spent half the day yesterday getting the network diagnosed (4 switches and 11 machines) and getting the DSL and routers configured and working again. Third lightning hit in the 20+ years I've lived here, the house is the highest one in the immediate vicinity, probably the reason... Did you lose any computers or GPU's? Must have been pretty loud, eh? I've been watching it on CNN & FOX, you guys have been getting hammered pretty hard with tornados and T-storms back east plus a heat wave too. This time of the year we worry about forest fires, some real dimwits out there camping. |

Third lightning hit in the 20+ years I've lived here, the house is the highest one in the immediate vicinity, probably the reason... I woke up at 2:26 AM (looked at the clock next to the bed). Didn't know why but got up and wondered around the house for a few minutes. Then there was another close hit about 10 minutes later. Took a look at the network and guess what, it went down at 2:26 AM. Worked until about 5 AM and got the network mostly running, but the DSL modem was completely fried so no internet. Lost a switch (had a spare though), 1 970 MB dead and 1 GPU is acting flaky, probably damaged. It won't run GPUGrid any more but will run some other projects. Think I was very lucky not to have lost more. A friend lent me his old DSL modem as he switched to cable a couple months ago (over 20x faster than DSL and cheaper), so at least am back on the internet. Sure wish I could get that cable connection but they stopped the line about a mile from here. In fact I might not have had a problem at all with cable, as the problem is ALWAYS that the surge feeds into the house through the copper DSL line. Wonder if optical DSL would solve the problem, but it's not available here yet. 1.5 Mbps copper only, thanks CenturyLink. Not! :-) |

On the other hand a full CPU core/thread is needed for the GF600 (and presumably GF700) cards. So these cards are more likely to be impacted by a PCIE reduction due to high CPU usage I don't think so, as the added CPU usage appears just to be polling the GPU, i.e. equivalent to SWAN_SYNC=0. On older cards SWAN_SYNC=1 is still being used. And thanks for clarifying the socket issue. In my mind it was clear that I meant "you'd need a larger socket for more lanes".. but this is not what I actually wrote :p MrS Scanning for our furry friends since Jan 2002 |

Last night we had another big lightning storm and 2.75 inches of rain. This time had a surge through the power lines. Lost a network port on one MB and an HD 5850 GPU on another PC. Five GPUGrid WUs crashed and burned. Swapped in a spare GTX 460 so the end result is that I have one more GPUGrid client running. Maybe Thor just likes GPUGrid :-) |
