You are gonna be infinitely far from apaartment 278...

BTW, congratulations

Not infinitely far, transcendentally far. :) And if one could ascend an imaginary staircase from 278 to 314, the distance would be -1, since as Herr Euler (after whom e is named, after all) showed, e^(i*Pi) = -1. So you would actually *descend* an imaginary staircase to go up the 1 floor from 278 to 314.

Thanks - but this was just the apt-search and lease-signing, so while getting that behind me was a huge relief, the actual move remains. I've been sorting and packing for hours every day since beginning of July.

Pi starts with 3.14159265. Now that I think about it, a few years ago America’s population would have already gone past 314,159,265.

Tis the season!

Perhaps March should be made pi month, since the number pi is exactly 3, as per The Institute for Pi Research.

Google calculated π to 31.4 trillion decimal places:

A little disappointment that there was no new added code/math in the computation as they have just used y-cruncher.

Let's just pretend I maybe have "175TB of storage" and "25 computers" at my disposal...how difficult would it be to run this just as a experiment?


edit: I'm sorta looking into setups that are similar to how HPC clusters are set up with software defined storage and virtualization, with a fast (40-100Gb eth/IB/OPA backend) so this could be a cool project to do testing with. (and get some publicity for GIMPS)


p.p.s...96 vCPUs....that's like....3 physical nodes for me.

I'm sure its been discussed before ... but ... is there pi in pi?
Precisely how many digits of pi can be found with these 31.4T digits; obviously NOT starting at the beginning?

Emma and I are going to talk about this at Google Cloud Next.

Most of the interesting stuff is the number of ways that y-cruncher managed to break the platform. IOW, GCP hasn't really been stress-tested on anything memory-intensive. When the application overwrites a terabyte of memory every few minutes, it causes all sorts of problems. Likewise, network-attached storage isn't 100% reliable.

Then there were other silly things like exceeding the EXT4 filesize limit.
