The FAQ is mostly just a rehash of the one that is found in the (D2OL)™ Support Forum, but since I wrote that one, there is no reason why I cannot use it here. If you have any questions not answered here or wish to have something added to the FAQ; please e-mail me and I will be happy to get back to you with an answer.
Q: Can I condense multiple nodes into one, or can I delete nodes entirely?
Q: How do I get an old Node ID back?
Q: How do I restore a previously backed up Node ID to my new install of (D2OL)™?
Q: Can (D2OL)™ run completely in the background, with no Task Bar icon?
Q: Can (D2OL)™ run as a WinNT/Win2000/WinXP service?
Q: Why does my client hang at certain candidates?
Q: Is there a program I can use to monitor my clients' progress?
A: No, you can not condense or delete your nodes. You can only delete nodes with no results credited to them — but if they have any work credited to them they must stay. Look at it from the point that if 1,000 users each have a node with only one result returned to it, to each user it may seem insignificant, but to the project they still equal up to 1,000 completed candidates.
A: Bad news here. Unless you have previously backed up your node.prp file then the Node ID is forever lost. Please read the What is a node? question and answer for more information on how to backup your node.prp files.
A: This is very easy to do. In the Windows version, right after you install (D2OL)™, it will display a window asking for your e-mail address. Simply cancel this and navigate on over to C:\Program Files\SengentD2OL\D2OL\res\ and paste your backed up node.prp file back into the 'res' folder. Now you can start (D2OL)™ and it will use your previous Node ID.
For Mac OS X, just CTRL-click on the SengentD2OL icon in the Finder Applications window and select Show Package Contents. From there browse to /Contents/MacOS/res and copy the node.php file.
The Linux client uses the same directory structure as Windows. Just navigate to the folder you installed (D2OL)™ to and browse the folders till you find the node.php file.
A: Yes it can, but only in Windows; you can either run it as a Service with Windows NT/2000/2003/XP, or you can run the program in different controller modes. You have a choice of the Lightweight Java GUI Controller, the Command Line Interface Controller and the File Bases Controller. More information about these different modes can be found in the readme.txt file in the C:\Program Files\SengentD2OL\D2OL\ folder.
A: Currently (D2OL)™ does not have service capability built into the client. While future versions may have some natively supported method, many users have had great success with FireDaemon. FireDaemon is a Service Manager which allows you to make any Win32 application start as a Windows NT Service when the computer starts up, allowing (D2OL)™ to do it's work even when sitting at the Windows logon screen. Please note the use of FireDaemon is unsupported by the D2OL staff; if you have a question or problem please ask inquirer about it in the Distributed Computing Arcana > Team Frozen Yogurt (TFY) thread on the Ars OpenForum.
A: You probably have a bad candidate. The most common reason this happens is that your Internet connection hiccupped when downloading your candidates. The easiest way to solve the problem is to perform a 'Flush All Tasks' in the 'Status' option and download new candidates. Not all candidates are created equal — some DO take longer to crunch than others. Flushing will not delete completed results - only the candidate currently being docked and your queue of unprocessed tasks.
A: Java is only used for the front end Graphical User Interface (GUI), also referred to as the (D2OL)™ Agent. The docking of the candidates is done with C++. Java simply enables the client to be ported to multiple OS platforms easily.
A: There is a known problem with newer Linux distributions and the (D2OL)™ client. More information about it can be found here.
A: Yes, there is: Team Frozen Yogurt member malör has kindly written a program for members named DSpy. It has real time monitoring capabilities as well as many node statistics. DSpy is a Windows-only program, but DSpython is also available for Linux (and possibly Mac OS X) users that have the Python scripting language installed on their computer; both can be found on our Links page. DSpy will also monitor (D2OL)™’s sister project, CommunityTSC.
