Hi All. I've got a computer at work that I'd like to run WU's but only in a strictly offline basis. The IT guys said I was sucking up too much bandwidth so I had to remove the program. I'd like to download WU's at home, copy em to a dongle then copy those to the work computer so it can crunch happily away. When the work computer is done, I'll copy them back to my home computer and upload em. Will this work? |

Hi All. Probably not, and you could get fired. Regards, A |

Hi All. Restrict the online-time to a few minutes a day ? Otherwise install a client on a usb-stick, download wu's on that stick and copy the whole bunch on the computer at work. Not sure it works. Shouldn't be a problem when bandwidth is the only issue. |

Hi All. From what I under stand it is very difficult because in the old days people would out right cheat by rerunning the same WU a hundred times for points so they made some checks to block this. These checks also block the easy movement of work from one machine to another. It can be done but it is not easy and I personally have never done this. I did not do the whole forums thing back in the old seti app days so I don't know exactly how the cheating was done but one of the things done when BOINC was envisioned was to block those specific cheating tricks. |

Don't think it is possible any more to easily move work units. A question for your IT folks, could you set the machine to bandwidth rate limit and perhaps only connect at off hours? Check the BOINC preferences. Of course if they don't want it to run at all, that is another matter. |

Less than 8,000 RAC is soaking up too much bandwidth? Really?? What kind of connection are you on? For a normal set of WU's, that's only about 75 WU's a day, or about 28 MB. Of course, shorties could easily triple that figure, but that's still less than 100MB a day (An average of about 1.2KBps, something an ancient dialup line could support). Of course scheduler requests factor into that as well, but I still don't see it being significant. |

seti sucks up cpu not internet bandwith....most likely they dont want foriegn programs on their computers, and losing computing power to something they might not agree with....i worked for a company like that...sucks, but its their hardware :) |

sucks, but its their hardware This ^ Work some overtime, save the money and buy a better CUDA card for your own PC, get more work done, everybody is happy. Ian |

You could try to DownLoad enough work, then quit the network and get them crunched!. You only need a INET connection to Down-- & UpLoad. (Some projects, like CPDN, who have very large, 100 to >500 hours WUs, use Trickle-Up Messaging, so they can keep up with yor progress and update stats). But DownLoading work on a different host, crunching them on another isn't considered fair, unfortunatly these possebillities were misused and are blocked! The way BOINC 6.12.34 handles DownLoads is quite different, compaired to 6.10.60, yesterday night I noticed about 40 WU's sitting in a DLoad-Qeue for some 5 hours, after I woke up they were still there, 1 push on a WU probably triggered the whole lot to DLoad and got me another 20 MB WUs. A even stranger problem appeared, when I decided, to install BOINC (6.12.34; 64bit) on a separare partition on a 3th DataDrive. (Maybe some people noticed the (VM) behind the CAL driver, haven't figured that one out, as I was trying a ReadyBoostCache, using a fast 8GByte SD card. Also looking and changing, security-settings and User Access Rights, which I hated in VISTA and never gave it a second thought, not a good idea, afterall!!!). Also run Einstein, Malaria, Rosetta, not an 'ideal mix' heavy memory and HardDisk use made the whole system sluggish and 4 MB WUs (also VLAR) on 2 5870 GPUs, with period_iteration=1 & 2 per_device, adds a screenlag, too. I removed PrimeGrid, I'm not really interrested in pure mathematical calculations, although it's usefull for better protection, larger bit sequence(>4096bit) and algoritmes. Still like SETI@home, Bêta also, Einstein, but also GPUGrid, Rosetta, Malaria, Docking, Leiden and Climate Prediction(CPDN) But I'm glad be to back, (with a little better health!) and hope there's still work, although sparse............ Well back on topic and [color=green]Keep On[b]CRUNCHING IN 2012 And Best Wishes For 2012, may health, fortune & wisdom, make it a happy year........................[/size] |

Hi All. Assuming the IT guys are okay for it to run, perhaps your best bet is to limit your network times to off-peak (or outside office) times. My ISP has a concept of peak and off-peak hours and different limits for each, so I try to make use of off-peak as much as possible by adjusting the settings in BOINC. |

why not install seti to the usb stick and run it off of it where ever. he'll keep the computer id ??? |

It's definitely possible. Search through boards I made quite detailed instruction how to do this some time ago. |

It's definitely possible. I also have some instructions for doing this in my profile. At some point I plan to make it a page on my site. Along with some other things like how to run BOINC in WinPE with GPUs. SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |

Otherwise install a client on a usb-stick, download wu's on that stick and copy the whole bunch on the computer at work. Not sure it works. This one works if you have the same OS on both computers (on Linux Machines anyway). You have to install BOINC to the stick, making sure you have both the BOINC and BOINC_DATA directories on the stick, then you can move it from box to box. I don't know if this arrangement will handle CUDA or not I have done this to copy work from a slow computer I wanted to shut down to a faster one in order to get it finished off and out of the way.

Otherwise install a client on a usb-stick, download wu's on that stick and copy the whole bunch on the computer at work. Not sure it works. In the windows version they have the data directory stated in a registry entry. So if you run it off a removable drive which changes letters then it can get a bit messy. The best way I found to avoid this is remove the registry keys for BOINC after installation. Then run it and connect to your project(s). That way the \BOINC program folder will also be the data folder. Then any machine you connect the removable drive to won't need registry entries to know where the data folder is located. The issue with that is the internet connected machine used for data transfer would preferably also be setup this way. So you could close the running instance on that box. Then run the portable one to up/download files. Then remove it and run the instance on that machine again. I did this for a bit running the router memory issues when my work connection couldn't access the project. As I already had my machines setup this way it was easy for me to stop the 22 machines and then copy them to one machine over the network. Then rar everything up to take home on my flash drive. The last file I still have back from September is only 1.5GB for all of those machines.
