We're back to that again, for the first time in a long time, IIRC. What's up, what are the limits, and when is it anticipated to go back to no limits? |

We're back to that again, for the first time in a long time, IIRC. I ave been looking into this for a day now, so I'll summarize what I've learned. Eric had to be called out Sunday to work the issue of Scheduler timeouts and excessive ghost tasks. "Results" in the field had swelled to 10.8 Mil, and 2 instances of runaway hosts with thousands of ghosts were reported in the forum. Eric's comment on Sunday was that limits were needed, and apparently they were installed during Monday's unscheduled downtime. From observations in the Panic Mode thread, the limits appear to be 100 cpu and 100 gpu. How long? Guess that depends on a return to stability. My log show that we're not there yet.

Eric si most certainly one of those who goes "above and beyond the call of duty". We must give him thanks, along with his long suffering wife Angela. Eric and Angela, step forward and receive our grateful thanks.

Thanks for the feedback. One of my hosts has about 1000 ghosts, the other, maybe a few hundred. A question: since each of my machines has 2 GTX 460s running 2 threads each, does that count as 4 GPU? Or two? (or, to put it another way, are the servers aware when a user runs more GPU threads than he/she has GPUs?) |

One of my hosts has about 1000 ghosts, the other, maybe a few hundred. Don't think the count / # of instances will make a difference. Paul Bowyer's Post in Panic Mode said he's being held to 100 for a 660ti w/ optimized apps, so would think he's running more than one at a time. This is just my guess on counts. Sorry for guessing, but there has been no hard info on the limits. Another Fred Support SETI@home when you search the Web with GoodSearch or shop online with GoodShop. |

My GTX 470 (single card) is pegged at 100 in progress, even though I'm running two at a time (count=0.5) |

When I got that message, when downloads were still getting through for me, I was hovering around 300-340 units pending with 3 CPU and 1 GPU task running with the tasks split 90 units in total for the 3 CPU and the rest for the 1 GPU but something like 95% of those were shorties. I was able to get new units on roughly a 1 to 1 basis as they were getting done and reported. Of course this was during the short time before the scheduler got funky for me again.
