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.
