With LLRnet, you can perform LLR tests automatically. No need to mess with reserving/reporting ranges and all that stuff. No need to worry about whether your machine will run out of work in the middle of the night or while you're on vacation. Just set it and forget it!
LLRnet is very simple to set up--in less than 5 minutes you can be all set and crunching away! It's perfect for users who just want to donate their spare CPU cycles to a worthy cause without adding a degree of complexity to their computer use. (That's not to say that it isn't great for advanced users, too. ) It's also great for work computers, since you can set it up on a computer and not have to worry about having it run out of work while it's not accessible. (Sorry, LLRnet doesn't currently work with HTTP/SOCKS proxy servers. There is one workaround that I know of, but it's more technically oriented--if you're interested, either PM me or post here.)
Here's all you need to do:
1. Download the LLRnet client software for your operating system. LLRnet is available for Windows, Linux, and FreeBSD.
Click one of the following links to download LLRnet:
Windows
Linux
FreeBSD
All are 32-bit; sorry, no 64-bit version available. However, because of the type of work that LLR does, 64-bit would have minimal, if any, speed increases.
2. Extract the files from the archive you just downloaded. C:\llrnet is a good choice (or /home/username/llrnet for Linux users).
3. Navigate to the folder where you extracted LLRnet. Open up the llr-clientconfig.txt file in your favorite text editor. You'll notice a little ways down from the top a line that says the following:
username = "nobody"
Change "nobody" to your mersenneforum.org username. For example, I would set this to "Anonymous". This ensures that numbers you work on are credited properly to you in the stats that will be published periodically. (If you'd rather crunch anonymously, i.e. not have your crunching associated with your mersenneforum.org username, simply set this to something different. You can actually punch in anything you want here, though most users will probably want to punch in your mersenneforum username.)
Save the file, and close out your text editor.
4. Doubleclick on the file named "llrnet.exe" to start LLRnet and get crunching! (On Linux and FreeBSD this will be just "llrnet".) You'll see an LLRnet icon appear in your system tray if you're running Windows, and you can right-click on the icon and click a button to pop up a GUI from which you can monitor your work. You can click another button on the right-click menu to open up a console and monitor your work from there. (Note: When you want to close out the console window, don't just close out the window. Instead, right-click on the LLRnet icon, and click "detach console". Otherwise, you'll close out the LLRnet program, which you probably don't want to do.) Linux users won't see a system tray icon, but they will get a GUI that pops up if they're using the stock version. (If you want to get the GUI back up after closing it out, navigate to your LLRnet folder and run the remote-gui.sh file.) To see the console, you'll want to start LLRnet from a command window--navigate to the LLRnet folder, and type the command "./llrnet" (without quotes). (With the console open, simply press Ctrl-C to stop LLRnet.)
5. If you want to have LLRnet run automatically when you start your computer, simply right-click the LLRnet system tray icon and click "Add LLRnet service". Or, if you'd rather only run LLRnet when your username is logged on, click the Start button, and navigate to All Programs, then double-click on the item named "Startup". A folder window will open. In a separate window, navigate to your LLRnet folder. Drag the llrnet.exe icon, with the right mouse button, to the Startup folder, and let go of the mouse button. Choose "Create Shortcut" from the menu that appears.
For Linux, how you set a program to run at startup depends on your distribution. Just post a message here and someone will try to help.
LLRnet FAQ
Q: Is there a deadline for returning LLRnet results?
A: Yes. Currently the deadline is 7 days from the time when the number was handed out to your client. After 7 days, if you still haven't finished crunching your number (or simply haven't been able to return it yet even if it is finished), it will be assigned to another person.
Q: Can I cancel a number that I don't actually want to crunch for whatever reason, or is over deadline?
A: Yes. Simply open up a command prompt (on Windows it's Start>Run, then type "cmd" and press Enter), navigate to the LLRnet folder (by typing the "cd" command, such as: "cd c:\llrnet"), and type the command "llrnet -c" and press Enter. LLRnet will start, cancel the current number, and close. (Your command window will still be left open.) Note that if you have a cache size greater than 1 (the default is 5), then you'll have to enter that command again for each additional number in the cache that you want to cancel. (LLRnet will say "no numbers left to cancel" if you've canceled them all and you execute the command again.)
Q: Can I run LLRnet on a multi-core system and still utilize all the cores?
Yes, though LLRnet by default can only utilize one core. Thus, you'll have to run multiple copies of LLRnet. Simply, when installing, extract the archive you downloaded into as many folders as you have cores (such as c:\llrnet, c:\llrnet2, etc.). Then, configure the llr-clientconfig.txt for each core (you have to configure each installation separately--and make sure to change the GUIPort value to something different on everything except the first installation. You'll also have to change this value in the llr-guiconfig.txt for the installations that have been set to a different GUIPort.), and run the llrnet.exe (or "llrnet" on Linux/FreeBSD) in each installation. You'll see as many LLRnet icons in your system tray as you have cores--you can control each core's LLRnet separately. (You can also configure one core's GUI to control all the other cores, too, though that's a little bit more of an advanced topic--you can either try to figure it out on your own, or just post here begging for help. )
Q: I'm not constantly connected to the Internet. Can I set LLRnet to keep a larger queue to last until the next connect?
A: Yes. Simply close out LLRnet, open up llr-clientconfig.txt, set the "WUCacheSize" value to however many workunits you want to keep in queue, and restart LLRnet. The maximum is 100, though that should be more than plenty even for the small numbers we're doing right now.
Q: I'm on a team. do I have to do anything special with LLRnet?
A: Yes. Simply edit the llr-clientconfig.txt file so that the line that says
username = "yournickname"
instead says
username = "teamname_yournickname"
username = "XtremeSystems_yournickname"
Q: I'm already experienced with LLRnet, and I just want to know what to punch in to my already-set-up copy of LLRnet for it to work with NPLB. Out with it man, already!
A: server = "crus.dynip.telepac.pt"
port = 300
