| Abstract: |
The US National Gemini Office (US NGO), part of the Community Science and Data Center (CSDC) at NSF NOIRLab, has completed a project to upgrade
the IRAF-based Gemini reduction software to provide a fully supported system capable
of running natively on modern hardware. This work includes 64-bit platform ports of
the GEMINI package and dependency tasks (e.g., from the STSDAS external package),
upgrades to the core IRAF system and all other external packages to fix any platform
and licensing problems, and the establishment of fully supported Help Desk and distribution systems for the user community.
Early results show a 10–20× speedup of execution times using the native 64-bit
software compared to the virtualized 32-bit solutions now in use. Results are even better
on new Apple M1/M2 platforms where the additional overhead of Intel CPU emulation
can be eliminated. Timing comparisons, science verification testing, and release plans
are discussed. |
