Nersc cori live status provides researchers and system administrators with real time visibility into the Cori supercomputer at the National Energy Research Scientific Computing Center. This status feed helps users track jobs, hardware health, and overall system availability.
Accessing accurate nersc cori live status is essential for planning simulations, managing workloads, and troubleshooting interruptions on this Cray-based HPC system. The following sections detail practical monitoring methods, key operations, and user guidance.
| Metric | Current Value | Status | Last Updated |
|---|---|---|---|
| Batch Scheduler | SLURM | Active | Within 5 minutes |
| Node Health | 98% Operational | Healthy | Within 1 minute |
| Jobs Queued | 1,240 | Normal | Within 10 minutes |
| Jobs Running | 820 | Normal | Within 10 minutes |
| Network Throughput | 18.4 TB/h | Elevated | Within 15 minutes |
Monitoring Nersc Cori Live Status Dashboard
Users rely on the nersc cori live status dashboard to view up to date information on system health, queue lengths, and resource utilization. The dashboard aggregates data from SLURM, node sensors, and network monitors into a single interface.
Key panels on the dashboard include job queue trends, node availability heatmaps, and interconnect latency graphs. These visual cues help researchers decide when to submit large workflows to avoid contention.
Real Time Job Queue Insights
Queue Length and Wait Times
Live queue metrics show the number of pending and running jobs, helping users estimate start times for their workloads on Cori.
Partition and Priority Overview
Different partitions such as regular, debug, and standby have distinct priority levels and policies reflected in the live status feed.
Hardware Health and System Alerts
Node and Processor Status
The live status page reports any offline or degraded nodes, allowing administrators to schedule maintenance before broader impacts occur.
Cooling, Power, and Network Indicators
Temperature, power draw, and network link statistics are monitored in real time, with alerts triggered when thresholds are crossed.
Operational Procedures and Best Practices
Operations teams use the live status data to coordinate maintenance windows, balance load across racks, and respond to incidents swiftly.
Users are encouraged to monitor the nersc cori live status board before submitting batch jobs to align with current system conditions.
- Check the job queue length before large submissions.
- Review node health alerts to avoid interrupted workflows.
- Observe network throughput trends to select optimal job sizes.
- Follow NERSC advisory messages for scheduled downtime.
- Use the debug partition for troubleshooting interactive issues.
Optimizing Workflows Using Live System Status
Understanding nersc cori live status allows computational scientists to time their runs, select appropriate partitions, and avoid periods of high contention or maintenance.
By aligning job submissions with current system conditions, users improve throughput, reduce wait times, and make efficient use of allocated compute hours.
Advanced Monitoring and Integration Options
Advanced users can integrate nersc cori live status feeds into their own monitoring pipelines using API endpoints and standardized status exports.
This enables custom dashboards, automated scaling decisions, and proactive response strategies for large collaborative projects.
FAQ
Reader questions
How often is the nersc cori live status updated?
The dashboard refreshes every one to five minutes, with critical metrics such as node health updating as frequently as one minute.
Can I subscribe to alerts for cori system status changes?
Yes, NERSC offers notification channels including email and webhook integrations for major status transitions and incidents.
What does a degraded node status mean for my jobs? \ A degraded node status may lead to rescheduled jobs and reduced performance, so users should monitor job logs and consider alternative partitions if needed. Where can I see historical cori system availability trends?
Historical system availability and incident reports are published in the NERSC portal under status archives and monthly operational summaries.
