- Expansion Update - Pol
- Installation completed Jan. 25
- Added:
- 1 Extra-large node (40 cores, 1.5 TB RAM)
- 4 regular nodes (20 cores each, 256 GB RAM)
- upgraded RAM for 12 regular nodes (from 64 to 256 GB)
- The Extra-large node can take a GPU – but currently there is no real interest
- All tested and running
- RAM Policy & Queue Changes - Pol
- RAM is now tracked by SLURM
- Default: 2GB RAM per CPU
- Examples
- 16 CPU job, by default will be killed if it uses more than 32GB RAM
- 32 CPU job, will use all of a standard node
- 1 CPU job, 64GB RAM specified, will fully allocate a default node (previously, this
would not fully allocate a node)
- High RAM nodes: 16 existing nodes now with 256GB RAM
- Members of the default and priority queues
- Just specify more than 64GB RAM in your SLURM command
- Example: to schedule a High RAM node job– # SBATCH -mem 256000
- Queue changes to accommodate 256GB RAM nodes and Xlarge node
- Two new queues
- Xlarge: single node, pre-emptive queue for GravityLab (Yunes)
- unsafe: all nodes (includes Xlarge node), queue for everyone
- limitations:
- jobs can be pre-empted by other queues
- pre-empted jobs get re-queued
- Xlarge node not part of the default queue
- Hyalite Documentation - Pol
- Discussion - Pol/Jerry/Jonathan
- Heterogeneity
- Xlarge node moves us in a new direction
- With our job scheduling and management, it will work out fine
- CFAC funding for classroom nodes (Robert Szilagyi class)
- allowing us to keep classroom use separate
- discussion: classroom use should be seperate from regular Hyalite use
- MSU Cores: meetings & VPR
- discussion: RCi and Hyalite should be a core
- CyberCANOE Display Wall
- USGS & ALCES FLIGHT
ACTIONS
- We will send out to the group: information on ALCES FLIGHT & USGS
FUTURE AGENDA
- Hyalite RAM Policy
- Hyalite Storage Policy
- Hyalite Expansion Update
- CyberCANOE (display wall) installation
