I've been fooling around with large numbers for a little while, and seeing how slow my laptop is calculating prime numbers above 10^8, have been wishing I had a dedicated machine to crunch numbers... If I have the concept somewhat right, supercomputers essentially are clusters of CPUs on purpose-made motherboards all linked together to share workload. Obviously such a machine is out of the question, but I do know that there are dual-processor motherbaords available to consumers. Forgetting about that option, would it be possible to have two or more desktops running together and sharing workload? Or even one sort of main computer with all the bells and whistles, linked with several units that are pretty much just a motherboard and power supply? Or am I just talking stupid?

I think that it's fesible and maybe not totally impractical. For high speed computation, one problem is the "bottleneck " created at the network level. But if you have a very long-running process, offloading to a secondary machine starts to look attractive. It wouldn't take much to have one piece of software listening for commands/data, acting on those commands, notifying the sender of completion and returning requested data. I don't, however, know of anything like this for Windows (pardon the assumption). I'd contribute my old Celeron 0.666 GHz machine to the effort, though.

Hey, is there anything wrong with that Celeron of yours?

It's the same one that I offered to you a few weeks ago. Back then the only thing wrong was that it is on the Western edge of the US at this moment.

Yep. It's up for grabs.

I'm not surprised you're trying to unload it on someone. Check that speed rating - it's evil, I tell you!

have you thought of a Beowulf system?

I've also had a little experience working with fairly large numbers. I once calculated 256 to the power of 65,536. Don't remember the answer off-hand, but I recall it was around 157,000 digits long.

Can this functionality be emulated from sending an email from C#?

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
