1) Message boards : Questions and problems : Messages indicate no disk space for new tasks. (Message 26553) Posted 9 Aug 2009 by Mike Sr. Post: I found the problem. My preferences were set to leave at least 150GB free. When I stored a 4GB video file last week, BOINC could not allocate the specified 3GB for the projects since that would violate the requirement to leave 150GB free. I reset the parameter to leave 75GB and it downloaded 12 new tasks.

Note the last one says disk useage is limited to 0.0 even though I set the value to 3GB.

3) Message boards : Questions and problems : Messages indicate no disk space for new tasks. (Message 26542) Posted 8 Aug 2009 by Mike Sr. Post: I'm not sure what you mean. I've increased the allocated disk space from 2GB to 3GB but the the messages still say NO disk space or 0.0 space available.
4) Message boards : Questions and problems : Messages indicate no disk space for new tasks. (Message 26540) Posted 8 Aug 2009 by Mike Sr. Post: I'm running SETI and Einstein but have not gotten work for either for 5 days. Rebooting doesn't help. If I do an 'Update', Einstein says no disk space allocated but I've allocated 3GB in BOINC preferences. SETI says something similar. I can't think of anything I might have done that would cause this to happen. Does anyone have any suggestions on what's wrong and how to fix it?
5) Message boards : Questions and problems : Transferring Boinc to new drive after crash (Message 18207) Posted 4 Jul 2008 by Mike Sr. Post: I had a hard drive crash but have a copy of my BOINC folder from the failed drive. Can I transfer it to the new drive directly into Program Files and pick up where I left off, or do I have to start from scratch? OS = Win2k, SP4.
6) Message boards : BOINC Manager : Exiting with Data Left in Memory (Message 2266) Posted 27 Dec 2005 by Mike Sr. Post: When BOINC is exited normally, i.e. File>Exit, is the status of any suspended project work that was left in memory lost? How about running projects? Are they checkpointed or is any crunching since the last project initiated checkpoint wasted? Regards, Mike
7) Message boards : BOINC Manager : Help with Resource Sharing (Message 2170) Posted 22 Dec 2005 by Mike Sr. Post: Thanks everyone for the in-depth clarification. I'm only using a single machine at a relatively slow 2GHz but it runs nearly 24/7, so I wanted to optimize the efficiency. A few of the preference settings, like the resource share, are somewhat counter-intuitive since the default of 100 implies a percentage but apparently it's not. Same for the Write to Disk parameter which could be taken as a checkpointing interval but is not. From what I've read, checkpointing is a function of individual projects and not BOINC. I think I now understand enough to get the most out of my setup without going any further into the nuts and bolts, which was my intention in the first place. Happy Holidays to All, Mike
8) Message boards : BOINC Manager : Help with Resource Sharing (Message 2146) Posted 20 Dec 2005 by Mike Sr. Post: OK, I think I got it. Switching interval determines the minimum time slice, while resource share determines how many slices to give each project. The sequence of the allocated slices may depend on the LTD and STD but over a long period each project will have gotten its proportional share of the total time. Is that fairly close? Mike The resource shares and the switching time are both under your control, and are independent of each other. Most leave the switch at 60 minutes. If you set SETI to 50 and Einstein to 100 and Rosetta to 200, then it will run SETI for an hour, Einstein for an hour, Rosetta for two hours, Einstein for an hour, Rosetta for two hours, back to SETI... (1:2:4) or some seemingly random pattern somewhat like that. The "guarantee" on resource share actually isn't even "per day" - it's "in the long run". If you have a result, say from Einstein, that somehow (you shut down the computer for a week, whatever) is in danger of missing the deadline, BOINC will run Einstein _only_, nothing else, until it's able to make the deadline. But it keeps track of that, so it may then run _no_ Einstein for a week, letting the other projects catch up. Look up "long term debt" and "short term debt" in the Wiki for all the details. STD controls "what runs next", and LTD controls "what work to download".
9) Message boards : BOINC Manager : Help with Resource Sharing (Message 2142) Posted 20 Dec 2005 by Mike Sr. Post: Mike, The Wiki is your friend ... you can look up questions like this there ... But, simply put, the resource is your computer's time. WIth a 50/50 split your computer will give each project 50% of the available computing power. Note that this is OVER TIME... you will see one project or another running, but, over time, the average will be 50/50 ... For more complex "looks" I give shares from as high as 90 (at times) to as low as 1 ... My current "spread" is 1% to 50% with most computers having a 1% to 25% ... But, I run a minimum of two, and usually more like 8 or 9 projects on each computer. WIth more projects, SEVERAL can go off line and I will not even notice it ... when I use up the work for one project, I will start to run work more for the other projects. When the off-line project comes back, I will re-allocate effort to the project. So, If I change the ratio of the resource shares, will the 60-minute interval for switching between projects change? This is where I have problems understanding the concept. If BOINC switches from one project to the next at fixed intervals, as long as there is work to be done, then each will get the same amount of computer time, regardless of the resource share proportions? On the other hand, if the 60-minute interval is proportioned between two projects based on a resource ratio of 50-50, then a switch would occur every 30 minutes. I guess it boils down to the question, Is it the switching interval that is rationed out or something else? Thanks for taking the time to indulge a dunce. Regards, Mike
10) Message boards : BOINC Manager : Help with Resource Sharing (Message 2131) Posted 20 Dec 2005 by Mike Sr. Post: I searched for this topic with no luck so I'll ask. I've been running Seti for a few years and recently added Einstein but am confused about resource share. I set both for 100 which gives each 50%, but of what? They appear to be switching at the default interval of 60 minutes, so what is being shared? I remember years ago on a Modcomp II mini-computer, it gave each task a 50ms time slice so all tasks appeared to run simultaneously. BOINC seems to be "all or nothing" for each project for 60 minutes. My OS is Win2k with AMD 2400+ CPU, 512 RAM, 80G drive. Any clarification woill be appreciated Mike
