Some time ago (mid 2011), I was trying to use an AWS 64 GB machine for some largish work and discovered that I couldn't actually allocate anywhere near all of the 64 GB of RAM I was supposed to have access to. As I recall, writing a simple C program to do binary search to pinpoint exactly what the max amount of memory I could malloc was, it failed somewhere around 34 GB – so just over half of the memory I was supposed to have access to. Makes me wonder how much of this 244 GiB you can actually use when you spin up one of these machines.
