On: Homemade computer calculates pi to 10 trillion digits

[brianobush]

It is about pushing limits with a home computer. The processor itself was a 12 core Xeon processor, but all of the storage required - both RAM and disk is quite impressive.

I am working on a similar brute-force analysis, but I have access to a datacenter with many machines. Not so impressive.

I never considered the details of Pi digit calculation, but I was surprised to see how it's very dependent on IO:

"For large computations, the bottleneck is either memory bandwidth or disk bandwidth depending on the number of hard drives and their configuration."
