#Parallele access 2 monity serial#
Many applications are serial or can only scale to a few cores. Expanse supports shared-node jobs (more than one job on a single node).
Users requests will be evaluated based on number of jobs and job size. Expanse supports long-running jobs - run times can be extended to one week.The maximum allowable job size on Expanse is 4,096 cores – a limit that helps shorten wait times since there are fewer nodes in idle state waiting for large number of nodes to become free.Science Gateways requesting in the Maximize tier can request up to 30M core-hours.
Limiting the allocation size means that Expanse can support more projects, since the average size of each is smaller.

Expanse uses the Bright Computing HPC Cluster management system and the SLURM workload manager for job scheduling.Įxpanse supports the ACCESS core software stack, which includes remote login, remote computation, data movement, science workflow support, and science gateway support toolkits.Įxpanse is an NSF-funded system operated by the San Diego Supercomputer Center at UC San Diego, and is available through the ACCESS program. Every Expanse node has access to a 12 PB Lustre parallel file system (provided by Aeon Computing) and a 7 PB Ceph Object Store system.
Expanse also has four 2 TB large memory nodes.Įxpanse is organized into 13 SDSC Scalable Compute Units (SSCUs), comprising 728 standard nodes, 54 GPU nodes and 4 large-memory nodes. Statistics, Machine Learning & Predictive AnalyticsĮxpanse is a dedicated Advanced Cyberinfrastructure Coordination Ecosystem: Services and Support Advanced Cyberinfrastructure Coordination Ecosystem: Services and Support (ACCESS) cluster designed by Dell and SDSC delivering 5.16 peak petaflops, and will offer Composable Systems and Cloud Bursting.Įxpanse's standard compute nodes are each powered by two 64-core AMD EPYC 7742 processors and contain 256 GB of DDR4 memory, while each GPU node contains four NVIDIA V100s (32 GB SMX2) connected via NVLINK and dual 20-core Intel Xeon 6248 CPUs.
