I'm asking this question because I can't find it on here and can't seem to Google the right term.
So, a family member of mine is a L1 server operator at a huge bank and sent me a screen shot of one of their clusters. It's just a screen shot of task manager, but it clearly says it has 32 processors and 128GB of RAM. I know this cannot be one single computer, not even a 4 processor slot board with hexa-cores could make that happen. My question is, they are obviously interconnecting hardware and making the software think it's all one unit. How is this done? I'm extremely curious, I"m still learning and this has greatly intrigued me.
Thank you for any answers!
