Hi, I've been running S@H for a while now and can't figure something out. I recently changed both my online preferences and my local computing preferences to specify a minimum work buffer of 10 days. I had previously had this setting at .1 day which seems to be the default. I also specify 10 days for the Max additional work buffer. This second option has always been set to 10 days for me. I made the change because the number of work units that were being cached for me was insufficient for more than about a 2 day downtime of the SETI servers. The problem is that since I made the change, I see no difference in the number of work units in my local work buffer. My machine is regularly asking for more work units, but I get messages that say "The computer has reached a limit on tasks in progress." I ran out of CPU work units again during the most recent outage on 1/14-1/15. Thus, it doesn't seem that this option works. Does anyone else see this? Is there anything I can do to make it work, or is this a S@H restriction? Thanks in advance, Jon |

Just about everyone with a even a moderately fast processor ran out of work during the most recent outage. There are currently limits set on the number of work units you can have "in progress" - 100 per CPU (not cpu core) and 100 per GPU. You are bouncing off that limit. So there is little point in "playing" with your cache settings. It would be better to reduce them to 3/0.1 otherwise you find you are starved of work on a very regular basis due to some changes in the way the cache works.

Well, it's been in the News: Continued server problems. The limits are 100 tasks per CPU (not per core, but per actual CPU) and I think 200 per GPU. |

I can vouch for the 100 per CPU - I've been bouncing off that limit for weeks, and am still doing so. Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |

Thanks! I do remember seeing that news post, but I didn't associate it with this problem. Looks like we have to wait for the permanent fix. Regards, J |
