- I have to point out, it is an attempt to make this on-topic, all thanks to @JBH, so tell us in the comments how well we did. the old one is history now.
50 years ago my grandfather created humanity's most impressive computer
When grandpa dreamed, he dreamed big! he took the best tech of his day, from early solid-state hard drives to the latest derivative of the Motorola 68000 CPU, from the most amazing radioisotope thermoelectric generators to solar panels just like those on Skylab! Look, I'm not going to bore you with the details about how this thing was built — that's really not at all important to my question — but I will explain one more thing that is.
It's HUGE!
OK, two things...
It's IN SPACE!
Specifically, my grandfather's big honking supercomputer is floating out there, right now, 2021, in a Lagrange point. I can Telnet to it, I can play games on it... But here's my problem: what do I do with it?
You see, I have a few gambling debts...
Who knows what grandpa did with the thing, but it's up there, running just fine, and when he passed away he left it to me. Now I need this thing to start generating some cash! Don't worry why, that's not really important either... but what is important is this: its computational prowess is something on the order of 1.9 zettaFLOPS. I'll let you work that out in your head for a moment. (This easily blows away most of the top 500 computing systems in 2021 combined.)
But it's worth remembering, 50 year old tech! That means the machine works through massive parallelization. I really meant it when I said the individual processors are like Motorola 68000s. I know the OS will have some impact on your answers, so please believe me that it's a somewhat souped-up version of SunOS 1. Yeah, 1980s... where do you think they got their ideas? Hah! Grandpa! I'm kinda hoping that your answers won't depend on the OS, just so you know.
Now, if you really want to know the details, I'll tell you, but honestly, it's completely unimportant. How that monster got up there, what satellite network we use to connect to it, what operating system it uses, how it manages its power and maintains itself... it's all unimportant. The only thing you need to know at this point is that I'm clueless about how to generate some cash with this thing. I'm not at all interested in selling it (I'm sentimental!). I want to put it to some use!
So here's the question, folks...
I know this is a bit vague, but frankly, I think the sheer scope of this thing limits its potential uses and it's not like there's an infinite number of business models. So...
What business model can I apply to start generating some cash?
- Remember, I'm not going to sell it.
- Ignore costs of operation. Yes, they're sizeable, but if you're going to suggest something low-brow like online gambling... honestly, 1.9 zettaFLOPS... you didn't look up that number if you think something like that is an effective use of this machine.
- You can believe that I have the resources to ensure international-grade encryption (don't ask how we did it with SunOS 1 — it's a family secret!), so don't worry about how data is moved, how fast it's moved, or how secure that transmission is. This question is all about the computer.
- Look around, it's 2021 and it doesn't matter where you're living in the world. If you just learned about grandpa's legacy, then you haven't been reading newspapers for the last 50 years! What I have is a resource and I need your help figuring out how to put that resource to work. But remember... you need to use the resource the way it was intended, as a computer. No suggestions about blackmailing countries or I drop the thing on their capital. If it helps, assume I can't or won't move it and I certainly won't damage or destroy it! Look, I'll entertain, shall we say... shady... business models, but I'm no terrorist!
- If you're really caught up in how that thing got there or can do what it does... assume aliens helped grandpa do it. It won't bother me and it's as good an excuse as any.
- Finally, if you have any hope of being selected as my business partner, you'll explain why the business model you pitch is better than any other.
Some technicality
Connection to the thing is quite modern, even if on the side of the system it is just old fashion solar panels accepting laser beams, at multiple points with let's say 64kbit per receiver with a total capacity 100Gbit, and retrofit 100Gbit downlink. Good catch from @Alexander.
So yes, it not for big data be shuffled up and down, if we take just ram 16MB per each node thrn it takes 770 thousand years to upload download ram snapshot from all the nodes using that 100 Gbit link.
So mode of operation sending relatively small data - GB's, TB's, PB's sizes, expand it with calculations filter out those which aren't useful collect useful data which fits the bandwidth.
quite big limitation actually, which has to be accounted for. Which creates a significant difference to that another question.
Location seems to be important piece of information as well, thanks to @notovny and @Goodies
Location is lagrange point L1 of Sun-Earth, so it is the sunny side, it is how the thing gets its energy from and what makes flashing with leds for advertisement to be pointless, besides that it is 1.5 million km's away.
