Linking many computers together to make a big 'cluster' does exist, and has existed for a long time. However how these clusters work is not at all
like a PC.
You dont say for example decide to run some computer intensive task and it is instantly performed 100s or 1000s of times faster than on your desktop.
Each of the nodes of the server acts as a single CPU, and if your job only uses one thread, then it will run at exactly the same speed as though you
are to run it on your PC. The advantage to these systems is heavy parallel computing. 95% of PC users these days be it for business or for pleasure
would gain very little benefit in performance, and in fact performance i can imagine would actually be degraded.
The same can be said for quantum computing, my question for everyone is this... do any of you know how current quantum computers look like or operate?
In general their usefulness is in performing specific computations, and again the technical advantage to the the end user who wants to play games,
watch youtube and type the occasional document... you get zero benefit over what the current x86_64 processors give you. Quantum computers and Quantum
computing is often touted as the next breakthrough and give us orders of magnitude improvements in performance... well, thats because journalists
don't understand what the quantum computing people tell them, and further more, when one of these labs tries to explain what they are doing, even
physics dont really understand what they are doing either... so it is currently a bit of a mystery and can be touted as anything you want it to be.
The only people who benefit from it are people running simulations of some form... be it 3D, video or raw computation... and the above post is
correct... there is a baseline if you have 4 cores and 4gb of ram, the computer will fall over if you try and run 4 machines on it that max out the
ram... and instead of taking out 1 user, you take out 4. This happens in reality, and iv experienced it in cluster computing.
Anyone used X11? I can imagine it would be similar to that, and even on a good fast network its not exactly lightening fast.
