I hope you're able to come back soon JPM. |

The idea behind S@H was to use spare cycles Isn't it true that that it's always been like that? Free cycles never meant that the electricity used when BOINC kicked in was free. Although that's what I used to think when that "free" term was used and now I know it's not so when I get my fuel bills. flaming balloons |

Actually, I think that low-power idle instructions on the CPU were not always available. Back in the 386 and 486 days, I believe free cycles were actually free--the CPU essentially ran at 100% all the time. I could be wrong on that of course. |

Ah, so we were lending our wear and tear to BOINC and now wondering why it's an arm and a leg it's costing us. flaming balloons |

That's generally true, even through the Pentium II's and Pentium III's. Of course there were always low power versions of every Intel/AMD chip (the 386SLC and 486SLC are examples), but the ability to turn off unused portions of the processor or to down-clock itself is a relatively new invention. With the advent of power saving features, distributed computing is a harder "sell" to the average person who ends up paying a higher electric bill. |

Sten, don't go optimistic on us now! The Arecibo schedule starting August 27 shows the ALFA receiver being put back on the telescope September 1 and the A2010 ALFALFA project's fall observation campaign starting ~03:00 UTC September 6. When some of that data gets shipped to Berkeley, it will be mainly midrange ARs. In terms of our demand versus data availability, with no ALFA observations between July 24 and September 6 I hope there's enough in HPSS storage to keep the flow going. If not, there may be an opportunity for the project to do some local maintenance or reorganization which is difficult while in full operation. Although there's ample data from GBT to fulfill all demand for many months, I judge the project will want to do careful testing of modified applications before starting production crunching here.

Thank you, Joe. That news bodes well for the future here. If the WU supply runs out before the September data starts arriving, the kitties will just prowl about waiting to pounce when the time is right! "Freedom is just Chaos, with better lighting." Alan Dean Foster |
