SUMMARY:Early Experiences with Charliecloud for HPC
DESCRIPTION:Richard Lawrence (Texas A&M University)\n\nContainers have bec
 ome an increasingly important part of the research software ecosystem for 
 enabling portability and reproducibility, especially for cloud-native work
 flows. However, challenges remain for facilitators working to bring the su
 ccess of containers in the cloud to their local HPC clusters due to strict
  security and performance requirements. Established container runtimes suc
 h as Singularity sacrifice features in order to meet these requirements, l
 eaving some researcher’s needs unfilled. Charliecloud, a newer container r
 untime, offers a more complete container experience for HPC by being fully
  unprivileged at all stages of container development, testing, and product
 ion. TAMU HPRC, an early adopter of Charliecloud, reports on its experienc
 es in supporting Charliecloud for HPC to provide guidance and inspiration 
 for other institutions considering supporting Charliecloud. Lessons learne
 d about installation, usage, best practices, applications, and user traini
 ng are described, as well as recommendations for further development.\n\nR
