A cluster is used to work on distributed computing tasks. So things that need a lot of number crunching. The idea is to run many processes at the same time to make the whole run quicker. Note that often the single processes will take longer because they need to be assigned and marshaled etc (overhead) but running many at the same time makes it worth it.

A GUI , which is what your desktop is, is not suitable for this because there are many different processes that run at random times. The best way to speed up desktop is:

• Faster disk
• Faster/more memory
• 64 bit OS to tack advantage of memory
• Faster processor
• More cores on processor
• More caching memory
• Etc

(the above list is not in any order)

So the short answer is “no”😊
