115 was solved with a little more than 300GB of, wait, checks notes, “files”.
That was your first rant, exabytes lol.
I hope no SSDs were lost solving 110 and 115 with this program. RIP SSDs and all of your exabytes that you stored. 😁
Was it completed before the expected number of kangaroos of each type filled each set, to reach even a probabilistic 50%? Without such details, the best I have was estimates, and the estimates derive from the number of operations.
So if you tell me the data storage was 100 kB after 2**58 operations, anything is possible, but that would just mean not a lot of DPs were found, not that the estimates were wrong.
Does the required storage per entry scale linearly when you increase the DP? Because logically, a higher DP under a higher keyspace requires way more jumps to find all DPs, which means the travelled average distance of any kangaroo increases in size, which means your storage also increases in size because you have to store longer distances.
Also, the jumps (each jump) aren't stored. All the kangaroos are jumping via jumps but only those that land on a DP (leading 0s with this program) are stored.
I think for 115, it took a total of 2^58.36 total jumps and the workfile(s) contained 2^33.36 DPs (DP 25); and it took right around 13 days to solve. 130 at DP 32 would contain a little more than 115 at DP 25; but even if you doubled it, you are looking at 600+GB, triple it 1TB, quadrupled it 1.4 TB, etc. it is still no where close to 1 exabyte of storage required.
Distances do not really increase in size, in the same range/group. They are spread out randomly at program start and then, for say 115, they have average jump size of somewhere around 2^57ish; so each jump is about 2^57, but inside a 2^114 range, so in order to really increase, each kangaroo would have to make more than 2^57 jumps (which would take a lifetime).
But yes, a larger range would have more hex characters stored for the distance (which would take up more storage space), compared to a smaller range, but the points (DPs) would all be the same size/length, regardless of the range. So 130 compared to 115 range would equal around 3-4 more hex characters per distance.
