| Summary:
The X-Ray Imaging and Spectroscopy Mission (XRISM) is the 7th Japanese X-ray
observatory, whose development and operation are in collaboration with
universities and research institutes in Japan, U.S., and Europe, including
JAXA, NASA, and ESA. The telemetry data downlinked from the satellite are
reduced to scientific products by the pre-pipeline (PPL) and pipeline (PL)
software running on standard Linux virtual machines on the JAXA and NASA sides,
respectively. We ported the PPL to the JAXA "TOKI-RURI" high-performance
computing (HPC) system capable of completing $simeq 160$ PPL processes within
24 hours by utilizing the container platform of Singularity and its "–bind"
option. In this paper, we briefly show the data processing in XRISM and present
our porting strategy of PPL to the HPC environment in detail.
