32 bit data structures (pointers, integer representations, single precision floating point) have been past their “best before date” for quite some time. R itself moved to a 64 bit memory model some time ago, but still has only 32 bit integers. This is going to get more and more awkward going forward. What is R doing to work around this limitation?
We discuss this in this article, the first of a new series of articles discussing aspects of “R as it is” that we are publishing with cooperation from Revolution Analytics. Continue reading R in a 64 bit world
I am going to come-out and say it: I am emotionally done with 32 bit machines and operating systems. My sympathy for them is at an end.
I know that ARM is still 32 bit, but in that case you get something big back in exchange: the ability to deploy on smartphones and tablets. For PCs and servers 32 bit addressing’s time is long past, yet we still have to code for and regularly run into these machines and operating systems. The time/space savings of 32 bit representations is nothing compared to the loss of capability in sticking with that architecture and the wasted effort in coding around it. My work is largely data analysis in a server environment, and it is just getting ridiculous to not be able to always assume at least a 64 bit machine. Continue reading I am done with 32 bit machines
