Just think of it as 'The scheduler couldn't find anything for your device', and consider that that means either it wasn't eligible or else the scheduling system was short of work (or clogged up). It's a pity we can't tell the difference between these situations, but we're stuck with it. Just what I wanted to determine. because if my machine is not eligible, I would like to know the reason why. I keep getting MIP1 work units and am doing them OK, but I do not get any of the others I am accepting. I am also grinding out ClimatePrediction work units (that are about three weeks long on my machine), but I have never received an ARP1 work unit. I have some files related to this, though. boinc[~/projects/www.worldcommunitygrid.org]$ ls -l | grep -i arp1  |

20054 World Community Grid 03/12/2019 15:32:09 Tasks are committed to other platforms OK: just a case if no ARP1 work for Linux machines then? I have been getting some ( 2 today) for my Linux machines. Cheers Got 2 10hrs ago.

@Jean-David Beyer
By eligible it means, at the very least, matching the devices given WUs which have been sent out already, but which need a wingman to verify the result. This is why, when there is a scarcity of WUs, it's especially hard for those running Linux. But it may be more than just OS family, it depends on the project. It may also be 32 vs 64 bit architecture. And, if it is a resent WU, your machine must be 'reliable' (likely to return the WU quickly enough). Really, don't don't lose any sleep over it. With this project the main problem at the moment is simply the shortage of WUs. The only way you can improve your chance of getting any is to ask for them more often. |

Just to make it clear, I have been getting some arp1 work. It is just that when I don't, which is most of the time, I get the message no work available for mcm1 & mip1 and work committed to other platforms.
As I am only asking for 3 projects, the 'other platforms' message must refer to arp1. Judging from the comments here from Linux users (as opposed to my MS), the message doesn't seem to mean what is says. Nor do the other 2 because my designated cache is full for those schemes and I get some whenever it is not full. Mike |

And, if it is a resent WU, your machine must be 'reliable' (likely to return the WU quickly enough). My machine is 64-bit 1.800 GHz 4-core Intel Xeon processor with 10240 KBytes cache, 16 GBytes RAM, etc. My distribution of Linux contains run-time libraries for both 32-bit and 64-bit programs. ARP does not know if my machine is reliable or not, since they have never seen fit to send me a work-unit to find out. WCG probably knows, though. |

There was a discussion with Uplinger (above in this thread) about what reliable means. It seems that until your machine has returned 10 consecutive valid WUs for a given project it won't be regarded as reliable for that project. There are also turnaround requirements which are system wide, but they've been playing with the numbers for that because of the WU size for this project.
Really, its not worth worrying about these things unless you're prepared to read a LOT of forum entries. Just believe that the techs really do try to make everything as fair as they can -- and there are crunchers who keep them on their toes if they slip up. But, in my experience, they're really well on top of all this stuff. |

Wow, been crunching almost 20 years (here and there on and off), and didn't know some of this! Thanks to all of you on this page who have enlightened me.

Shutting down the Linux hosts. Not worth the electricity to keep them running for 2 or 3 tasks per day.

Just be sure to install the 32-bit libraries (instructions are posted in the Linux section), or you will join the legions of crunchers who really are wasting their electricity. |

I have run CPDN in the past but only run the extra hosts here for betas and new projects and then only until I get 5 years on any new project. Would normally only take 2 weeks or less to get there but with the limited amount of work available for ARP I can no longer justify the costs. Have to watch the electric bill.
