Computational fluid dynamics on the AWS cloud
Introduction

Procedure
- Resource tagging per HPC Club policy
- Link
- Project tag key; value = NetID (without ‘@uw.edu’)
- End_date tag key; value = when you expect to be done with the resource
- Name tag key; value = NetID_descriptive_phrase
-
Central idea: Use the Spot market, do the first calculation, make sure it works, get cost
-
AB can assist with getting the technical details right
-
Authenticate with NetID possible but we will use IAM User for now
- Procedural
- Create cfn cluster with placement group
- See email chain for links
- optional: disable hyperthreading (config file and post_install_script required)
- install starccm+ on the shared volume, set up the license
- A making progress on the execution issue; please send Rob confirmation this is fixed
- create a snapshot of the volume for next cluster
- create a qsub file and launch
- created from starccm+ documentation; get file from Siemmens, cf email chain; pls send to Rob
- Create cfn cluster with placement group
- Number of processes / instance depends on number of gridcells in the CFD calc
- LH: 50k cells per process
- LH: 72 processes implies qty 2 c4.8xlarge with hyperthreading on; qty 4 if off
- A revises: 9e6 cells 180 processors = 4-5 c4.8xl
- ‘existing config does not have a placement group’ implies new cfncluster needed
- Obstacle
- Insufficient space on the shared EFS drive… solution pending
- The Steve’s Portal
- This is the starccm+ website
- batch/qsub documentation available
