practical desktop grid solution


Is there a practical desktop grid computing solution available today?

My laptop has various development tools on it, plus productivity tools, oracle lite and some obligatory games. When I plug into my home network, there are often other trusted machines sitting idle. I want my laptop to spread the load out to those available resources.

Is this want fulfillable at this time to any degree?

No, I do not believe so. Clustering, as I understand it, is more about high availability. You place your application on several servers and they act as a single application resource insuring that the business functionality is always there even if you have high user traffic or one of the server fails. I think that servers in a cluster will all have the same applications installed on them.

From what I can glean about grid computing, it is more about the sharing of processor time and memory(?) among several machines, sort of a multi processing manager that spans two or more computers. Until recently I believed that applications had to be specially designed to take advantage of multiprocessors as well as grids, but in reading several articles over the last few days, I am no longer so sure.

Desktop Grid Computing seems to be a buzzword, but I cannot quite decide for what. I was hoping for either answers or pointers to where I might find answers. Basically, I want to know if there is a way that I can have the applications I am running on my machine co-opt unused processor time on other trusted (and trusting) machines on the network.

hi,
nowsaday there are several free solutions to get your own DesktopGrid so that you can use your spare CPU time.
Unfortunatly, you cannot install and use it out of the box. You must at least be aware of computing (even if you don't need to be a guru ), OS management and sometime have a little skill in software development.

- Xgrid by Apple comes with Mac OS X
- Boinc by Berkeley (http://boinc.berkeley.edu) is Seti@Home version 2
- XtremWeb (http://www.xtremweb.net)

Hope this helps,
Oleg

Then there's the Beowulf project which, although it calls itself a cluster, sounds more like your definition of a grid than your definition of a cluster. I'm not too hot on the technicalities of either term. Once again, it seems more than trivial so some reasonable computing knowledge is required.

looks great but dedicated to linux only
Boinc and XtremWeb are plate-forme independant.

Beowolf also expect to (re)write compatible programs (or at least recompile with MPI or PVM libraries). Xgrid and XtremWeb don't

Finally it seems not free

another point about these platforms: they are not trivial to install if you want your own desktop grid platform.

But if you want to participate to such a platform (i.e. provide your CPU idle time to others) it is generally very easy : a package installer is provided for several OSes
