| Summary:
The X-Ray Imaging and Spectroscopy Mission (XRISM) is the seventh Japanese
X-ray observatory whose development and operation are in collaboration with
universities and research institutes in Japan, the United States, and Europe,
including JAXA, NASA, and ESA. The telemetry data downlinked from the satellite
are reduced to scientific products using pre-pipeline (PPL) and pipeline (PL)
software running on standard Linux virtual machines (VMs) for the JAXA and NASA
sides, respectively. OBSIDs identified the observations, and we had 80 and 161
OBSIDs to be reprocessed at the end of the commissioning period and performance
verification and calibration period, respectively. The combination of the
containerized PPL utilizing Singularity of a container platform running on the
JAXA’s "TOKI-RURI" high-performance computing (HPC) system and working disk
images formatted to ext3 accomplished a 33x speedup in PPL tasks over our
regular VM. Herein, we briefly describe the data processing in XRISM and our
porting strategies for PPL in the HPC environment.
