61) Questions and Answers : Windows : Boinc installs but does not run (Message 4777) Posted 29 Sep 2004 by John McLeod VII Post: There is hopefully a B in a circle on the task tray. Double click that to bring up the GUI. From there, you can go to settings - attach to project to get started. <a href="http://www.boinc.dk/index.php?page=user_statistics&project=cpdn&userid=13"><img border="0" height="80" src="http://13.cpdn.sig.boinc.dk?188"></a>

63) Message boards : Number crunching : AT 94% complete, BOINC (Message 4667) Posted 26 Sep 2004 by John McLeod VII Post: How many days is your cache? And how many hours are left on the first WU? If the number of hours left on the first WU is less than the number of hours of cache, then this is completely normal and expected behavour. <a href="http://www.boinc.dk/index.php?page=user_statistics&project=cpdn&userid=13"><img border="0" height="80" src="http://13.cpdn.sig.boinc.dk?188"></a>

The other way is manual, and requires the person to either send an email, or post the WU ID. Automatic is better, as someone will forget to send an email or post here. <a href="http://www.boinc.dk/index.php?page=user_statistics&project=cpdn&userid=13"><img border="0" height="80" src="http://13.cpdn.sig.boinc.dk?188"></a>

67) Questions and Answers : Wish list : BOINC in a GUI application for Mac OS X? (Message 4506) Posted 23 Sep 2004 by John McLeod VII Post: BOINC is developed at berkeley, not CERN. If there is a CLI version, there will be a GUI version eventually. The plan is to have every installation a CLI with the GUI controlling the CLI. <a href="http://www.boinc.dk/index.php?page=user_statistics&project=cpdn&userid=13"><img border="0" height="80" src="http://13.cpdn.sig.boinc.dk?188"></a>

It would have to give 100% cpu to a WU that was in danger of being late, and then not allow that project to download more work for some time in order to allow other projects to catch up. Note that the CPU scheduler cannot wait until the deadline has passed to give all of the resources to the late WU as that is too late. I believe that it is possible: 1) Allow debt to be negative. 2) If the estimated time to crunch a WU is ever 80% or more of the time remaining to the deadline, that WU gets 100% of the crunch time until it is less than 80% of the time remaining to the deadline. If a deadline is less than 12 hours away, that WU is to be completed immediately even if the crunch time is less than 80% of the time remaining to deadline. 2a) In the case of conflicts in 2 where there is more than one WU that meets the criteria, the WU with the shortest deadline gets the priority. 3) A project that has a negative debt will not be eligible to DL new work unless no work is available from any project with a higher debt. 4) If during downloading of work, any WU arrives where the estimated crunch time meets condition 2, do not download any more work from anywhere. 5) If a CPU is idle, download a WU from the project with the highest debt that has work available. I have probably missed a case. Implementing this is not going to be easy. <a href="http://www.boinc.dk/index.php?page=user_statistics&project=cpdn&userid=13"><img border="0" height="80" src="http://13.cpdn.sig.boinc.dk?188"></a>
69) Questions and Answers : Wish list : Ability to delete a not used workunit (Message 4468) Posted 22 Sep 2004 by John McLeod VII Post: The database that maintains the state of each result requires that each result have a host attached. So, it will not be possible to delete a host that is no longer active. It should be possible to write code that hides the unwanted host. But I expect that it will not happen soon. Merging hosts is not based on the name, but on the OS and CPU. It could be important to know what OS/CPU combination crunched a particular WU (even if it crashed). If it crashed, it would be useful for debugging. If it did not crash, that host could be contacted again to attempt to crunch more on that WU. (I know this one has been retired). If the host has been retired, and a backup of the successful WUs have been made, some arrangement could be made to do the extra requested work somehow. <a href="http://www.boinc.dk/index.php?page=user_statistics&project=cpdn&userid=13"><img border="0" height="80" src="http://13.cpdn.sig.boinc.dk?188"></a>
70) Questions and Answers : Wish list : Slower computers getting more credit on each trickle (Message 4467) Posted 22 Sep 2004 by John McLeod VII Post: Here, there is a fixed credit per trickle returned as there is no validation. In any case the speed of a computer should not make much difference in the amount of credit granted per WU. The way is is supposed to work is that the credit for a particular WU is the same on any machine, but the credit / time is greater for faster machines as they can push out more WUs / (pick a time unit). <a href="http://www.boinc.dk/index.php?page=user_statistics&project=cpdn&userid=13"><img border="0" height="80" src="http://13.cpdn.sig.boinc.dk?188"></a>

78) Questions and Answers : Windows : BOINC & Explorer or Outlook (Message 4077) Posted 14 Sep 2004 by John McLeod VII Post: I haven't had this problem, and while my system is not exactly the same, it is similar. The one in question is a 2.0Ghz Pentium with Outlook 2003 and has about 30Gb free. There is a bug in 4.08 and possibly earlier that uses all of the CPU time when connecting to a server. If you have a modem, this can be especially pronounced. But once every 2 hours or so seems to be much to rapid for this machine between trickles. <a href="http://www.boinc.dk/index.php?page=user_statistics&project=cpdn&userid=13"><img border="0" height="80" src="http://13.cpdn.sig.boinc.dk?188"></a>
79) Questions and Answers : Preferences : Processing time (Message 3997) Posted 13 Sep 2004 by John McLeod VII Post: Since you are running multi project you should change your preferences to leave projects in memory while they are paused. The current version of BOINC does not wait until a checkpoint to switch, and all work since the last checkpoint is discarded if a project is removed from memory. <a href="http://www.boinc.dk/index.php?page=user_statistics&project=cpdn&userid=13"><img border="0" height="80" src="http://13.cpdn.sig.boinc.dk?188"></a>
