TECH: Jetstream - performance, early experience, and early results

Jetstream is undergoing its acceptance review by the National Science Foundation (NSF) at the beginning of May. We expect the system to be accepted by the NSF in short order and this abstract is written with the assumption that acceptance will be complete by the time final versions of papers are due. Here, we present the acceptance test criteria and results that define the key performance characteristics of Jetstream, describe the experiences of the Jetstream team in standing up and operating an OpenStack-based cloud environment, and describe some of the early scientific results that have been obtained by researchers and students using this system. Jetstream is a distributed production cloud resource and, as such, is a first-of-a-kind system for the NSF; it is scaled at an investment and computational capability – 0.5 PetaFLOPS peak – that is consistent with this status. While the computational capability does not stand out within the spectrum of resources funded by the NSF and supported by XSEDE, the functionality does. Jetstream offers interactive virtual machines (VMs) provided through the user-friendly Atmosphere interface. The software stack consisting of Globus for authentication and data transfer, OpenStack as the basic cloud environment, and Atmosphere as the user interface has proved very effective although the OpenStack change cycle and intentional lack of backwards compatibility creates certain implementation challenges. Jetstream is a multi-region deployment that operates as a single integrated system and is proving effective in supporting modes and subdisciplines of research traditionally underrepresented on larger XSEDE-supported clusters and supercomputers. Already researchers in biology, network science, economics, earth science, and computer science have used it to perform research – much of it research in the “long tail of science.”
