8. Cgroups
Altair Confidential 8
• Ensures jobs have access to requested resources
• Can restrict resources for PBS jobs, preventing OOM conditions
• Ensures accurate resource accounting
• Provides resource enforcement at kernel level instead of the
MoM polling for usage
• Consistent job runtime

9. Containers
Altair Confidential 9
• Lightweight virtualized environment for traditional HPC apps
• Number of containers that can be run on a host
• Time to launch a container
• All the goodies of containers (App maintenance)
• Conflicting requirements for applications (e.g., app can run only on centos 6, or needs an older library)
• Ease of packaging application into their own “containers” with all dependencies included.
• Natural extension to cgroups and cpusets
• resource constraining, CPU pinning, etc.

10. Cloud bursting

PBS Works
• On-demand use of cloud resources to
maximize efficiency
• Improve responsiveness, adding capacity
exactly when needed
• Automatic governance and cost controls via
site-defined policy and quotas
• Understands on-premise utilization, ensuring
bursting only when cost-efficient
• Vendor-agnostic: no lock-in
• Fast: 1,000+ nodes in minutes

11. Topology Aware

12. Energy Aware
Altair Confidential 12
DoD HPCMP
Yearly Savings (estimate)
• Eliminate energy waste with no loss in service
• turn off idle machines and backfill holes
• A/C savings by scheduling work onto cooler nodes

• fit more hardware into smaller datacenters
• run in degraded mode during power emergencies
• Per-job power profiles: power=600W
• Power saving mode: off, standby, …
• Power ramping: slow up/down
• Energy accounting: energy=64.2kWh

13. Nvidia DGCM Ready
Altair Confidential 13
• Pre-job node risk identification and GPU resource allocation
• Automated monitoring of node health
• Reduced job terminations due to GPU failures
• Increased system resilience via intelligent routing decisions
• Increased job throughput via topology optimization
• Optimized job scheduling through GPU load and health
monitoring
