Another issue facing the HPC community is the reproducibility of digital artifacts. The requirements for specialized hardware and scale often make experimental research products difficult to access and reproduce. To address this, SC established a Reproducibility Initiative requiring authors of submitted papers to describe their significant research products; the Chameleon cloud is the default infrastructure to facilitate artifact sharing as part of this initiative. Kate Keahey, an Argonne senior scientist and Chameleon PI, will lead a Birds of a Feather session on practical reproducibility – the sharing of reproducible digital artifacts in the face of the constraints of real-world applications. Researchers and practitioners will discuss lessons learned from their own reproducibility initiatives and will explore steps to improve artifact sharing and usage. Moreover, in a workshop collocated with SC24, Keahey will give a keynote address discussing how Chameleon’s bare-metal reconfigurability provides an excellent environment for reproducible science.
