377 physical servers and 32 network switches deployed across 10 racks.
|Computational Capacity||Heterogeneous set of 6,360 logical cores, with 6,172 cores dedicated for interactive or job-scheduled computational research. Resources dedicated for interactive or job-scheduled computational research have a combined single-precision computational capacity of about 232,754,000 FLOPS|
|External Network||Connections to UVA core-network switches provide the cluster with a theoretical inbound+outbound maximum network-IO throughput rate of about 2,400 MB/sec (most clients connecting wirelessly or by means of a gigEnetwork connection will experience inbound+outbound transfer rates of about 40-80 MB/sec).|
A non-blocking CLOS-3 Infinband network has a point-to-point inbound+outbound maximum network-IO throughput rate of about 5,600 MB/sec, the Nortel Baystack point-to-point maximum network-IO throughput rate is about 120 MB/sec for up to 4,800 MB/s worth of evenly distributed network activity across the entire Nortel Baystack.
Cluster Status and Monitoring
Rivanna has Ganglia monitoring enabled and is accessible to researchers with access to the system. If you have access to Rivanna and wish to see Rivanna's Ganglia metrics please:
- Create a SSH tunnel between your laptop/workstation and Rivanna for port 80. For example, on a MacBook Pro you would run 'sudo su -', then 'ssh -L 8080:udc-ba30-11:80 <your eservices ID>@interactive.hpc.virginia.edu'
