Crush is a medium scale virtualized research cloud. It is designed to be allocated for compute intensive work and to be used in tandem with the AVHE where the data and work scheduling infrastructure are maintained.
A primary use case for Crush is the provisioning of a “cluster within a cluster” providing access to dedicated, customized compute nodes for high-performance and high-throughput computing.
Currently Crush consists of 10,000 cores and 45 Terabytes of memory.
Crush is a dynamic resource, simultaneously supporting a wide variety of workloads, balancing allocation based on use and priority. A snapshot of recent workload includes support for Syracuse researchers in:
Nationally, Crush contributes computational time to the Open Science Grid.
