This sounds more like it ought to be an account manager and not a project.

Things that individual projects do not know, or at least do not track. Such as their actual resource share, number of hours per day machines are on. With information from many projects and many host environments, anonomolus tasks can be identified quickly, and rules created to help users purge such tasks from their machines. Work requests could be deferred from projects that are recovering from an outage to help it get back on it's feet. David Anderson wrote a paper and says you need 2.8 BOINC CPUs to get the equivalant of 1 dedicated CPU (such as comparing with a cloud or in-house cluster). But this is only true if you assume your project has the same average resource share, and the same crunching hours per day as the projects that were sited in the paper. If either of these varies, then the 2.8 estimation is of no value. But noone can really tell you if there is variation across BOINC projects because noone has the data. Do users tend to devote 70% share to SETI, but only 40% to Rosetta? You could try and infer data from the stats, but you have to assume things like the user has not changed their configuration over a period of time, and their machine was active for it's typical duration during the period studied, and all their debts were under control and all the client was able to get work from all of their configured projects. I certainly agree that a project controlling a client machine SOUNDS like it COULD be something to discourage. But keep in mind all of the participants that have been looking for new features and been told they cannot be implemented. Such as orchestrating one WU from a low memory usage project running along side one from a high memory usage project, rather then trying to run two at once from the high memory project. Yes, you can achieve some of that with the available extensive preference settings, but you can't easily see it is working as desired, and you still end up starting work that ultimately will grow to exceed the configured memory bound. Thus leaving uncheckpointed work hanging until memory is available. In some cases, the client firing up a string of tasks only to ultimately find each grows to exceed the memory configuration can actually make the situation worse by filling the swap space. Keep in mind that the only machines this project would be installed upon would be those that the participant WANTS it installed upon. So the only directives sent are based upon the participant's request. So it is a tool, not a virus. If the participant wants to shutdown everything but one project, this just gives them a means to do so that does not require opening up a firewall, driving 50 miles, or trying to direct their parent through how to use a mouse. And having such a tool exist in the world doesn't create any new exposures to network or security. In fact, it might actually be used to detect, report, and repair holes in security that users want to be aware of. It will enable a corporate environment to observe and control machines in a mannar that is currently only available to them if they have an open TCP port on every BOINC client machine. At present, this lack of control is one serious obstacle to getting BOINC installed in corporate and campus environments. The answers to the "what if..." questions such as "what if we decide we don't want SETI running on every PC in the school system?" are not pretty. What if a BOINC project is found to be rogue, can we control which projects the machines are allowed to attached to? Account managers, right, can we insure all our machines are running through the account manager? What if a task consumes 3 days of CPU time before finally ending in error, is there a way to purge it from our systems? Think of your own (BOINC project server lab) environments. Where the machines are all in your own lab?? Can we suspend production work on our machines, and have them immediately pick up test WUs from our internal alpha test project? ...well uh... not exactly. But they will TEND to do so once they hit a checkpoint, and update to the test project scheduler... but wait there's been no work there for days so the backoff is long... you want those machines to begin the testing within the hour. Isn't suspending your production project, and doing an update on the test project the ideal way to get the alpha work running? Such a mechanism could also be used to deploy software (in addition to BOINC updates), and better track and manage a fleet of machines. Thus offering an aid to that corporate IT director. It just depends upon how they have set up the BOINC environment and how they wish to utilize it. Such a mechanism could help manage a cluster of cloud resources and shut them down when they are not in use. If you fire up 50 machines in a cloud, running Linux, Windows and various BOINC versions, point them to a test project and have them run, wouldn't you want some kind of console to observe and control everything from? ...or would you rather jot down 50 IP addresses and manage each one directly? There are a lot of possibilities for such a thing once people can see how it works. Possibilities that promote BOINC, aid BOINC projects, and offer flexibility to BOINC users.

What you are attempting to do is discouraged to some extent. For instance, you don’t want a project to be able to suspend all other projects on the machine so it can have sole use of the machine.

So everything I (attempt to) do is running as the BOINC user, on the local machine, from within the sandbox. I can see that the BOINC user may be limited so far as snooping around the machine. That's what the sandbox is for. That is why I cannot count on snooping around to locate the boinccmd. And there could be more then one installed. I don't typically install as a Windows service, so perhaps I'm missing something. But sandboxes are made to keep things in, not out. Everything required should already be in the same sandbox as my WU's "application" script file from the slot directory. So, if I hit the right boinccmd, it will change to the data directory that I am running within, and not require a host name and password. Heck, I could actually open the ..\..\gui_rpc_auth.cfg file if I use file seperator appropriate for the host. But I still wouldn't know for certain where boinccmd is if the user seperates the data directory from the BOINC client code.

Boinccmd attempts to lookup the password by opening up the gui_rpc_auth.cfg file in the current directory ( On Windows, boinccmd changes the working directory to the data directory before looking ). If gui_rpc_auth.cfg cannot be opened it looks at the command line argument. If BOINC is installed as a service on Windows, or in a sandbox configuration on the Mac, then there are several permission issues to contend with depending on how your application is to be executed. When you say "BOINC App" are you referring to an application that the volunteer launches to control BOINC, or are you referring to an application that is launched by BOINC as a project application? ----- Rom -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Mark Pottorff Sent: Monday, February 22, 2010 12:06 PM To: Charlie Fenton Cc: BOINC dev Subject: Re: [boinc_dev] How to locate boinccmd on client According to the doc, the requirement for GUI RPC password only applies when you run boinccmd from some other subdirectory or machine. If I can locate the boinccmd from the same directory as the active core client, and contact the client via boinccmd rather then GUI RPC over the network, then I'm expecting boinccmd to be fully functional without the password. Are there other undocumented limitations on functionality? I see no mention of any reduced level of functionality. Either you're allowed, or you're not. Nor do I see any mention that Mac clients may not have boinccmd available. So please advise. I am tinkering with a "BOINC app" that allows monitoring and control of the client via browser rather then a direct network connection. All interaction to the client machine is done via BOINC scheduler and "application", so no direct network connectivity is required (beyond the normal BOINC client-pull scheduler protocol). How would you like to be able to abort a bad task on your alpha cluster, or set the debug flags on one of your alpha machines without having to actually locate the physical machine and run down there to modify cc_config? ...or detach all of the machines in a school system from a project, perhaps even uninstall BOINC, all from a website? I'm looking at installing BOINC client version upgrades as well, but need to locate command line arguments to suppress GUI. I seem to recall there are some, but haven't had a chance to track them down, so if anyone knows off-hand, I need to get that in my notebook. I still have a number of dots to connect before I am ready to launch an alpha, but by all means contact me directly if you have interest in using such a monitor and control system.

On the Mac, the user has the option of downloading the command-line version of teh client which includes boinccmd. They normally would install it in the standard BOINC Data directory at "/Library/Application Support/ BOINC Data/". But even if boinccmd _is_ installed, project applications do not have access to the gui rpc password under sandbox security, so they can only perform limited functions using boinccmd. I don't know if this is also true on Windows. What do you want your project application to do with boinccmd? In other words, for what do you want your application to use boinccmd? _______________________________________________ boinc_dev mailing list [email protected] http://lists.ssl.berkeley.edu/mailman/listinfo/boinc_dev <http://lists.ssl.berkeley.edu/mailman/listinfo/boinc_dev> To unsubscribe, visit the above URL and (near bottom of page) enter your email address. _______________________________________________ boinc_dev mailing list [email protected] http://lists.ssl.berkeley.edu/mailman/listinfo/boinc_dev To unsubscribe, visit the above URL and (near bottom of page) enter your email address.
