Using memory mapped files to conserve physical memory for large arrays(codeproject.com)

submitted by crpietschmanncrpietschmann(11.3k) 4 years ago

I have long thought about creating a disk based version of an array to store my data, but this would require a lot of caching logic to make it perform fast enough compared to physical memory. A couple of years ago I stumbled across Memory Mapped Files which has long existed in the operating systems and is typically used in Windows for the swap space. With even more data in my current project and running on a 64bit platform, the time seemed right to wrap this into a small library.
