Abstract

A review is presented of the current status of support for large FITS files (those greater than 2~GB) and 64-bit PC architecture in Linux software applications that are commonly used for astronomical data processing. We present solutions for the support of large FITS files on 32-bit Linux systems, together with a report on the status of 64-bit support in the Starlink and Python libraries that are used to process FITS files on Linux PCs. Our conclusion is that 64-bit astronomical software for Linux is now sufficiently mature that data centers can now confidently migrate to 64-bit PCs to overcome various technical limitations of 32-bit PCs.
