Cloud HPC Implementation
Building Infinite Clusters: Automation, Ephemeral Scaling, and Cost Control.
The Virtual Supercomputer
Cloud HPC offers infinite scale, but unlike an on-premise basement cluster, the meter is always running. Implementation is not just about installing software; it is about Infrastructure as Code (IaC) and precise Financial Orchestration.
The Ephemeral Model: "The Pop-Up Cluster"
Head Node
Small, cheap VM running 24/7. Holds the scheduler (Slurm) and manages the user login access.
Compute Nodes
These do not exist until a job is submitted. They spin up, calculate, and are destroyed immediately after completion.
Cost Saving
You pay for 100 servers for exactly the 2 hours they ran, not for the idle time in between.
Implementation Workflow
Step 1: Network & Security (VPC)
We build a fenced-off Virtual Private Cloud (VPC). A public subnet for the login node and a private, isolated subnet for compute nodes to prevent external threats.
Step 2: Storage Strategy
Data movement is expensive. We deploy high-speed managed services like AWS FSx for Lustre or Azure NetApp Files for scratch space, with S3/Blob storage for long-term archiving.
Step 3: The Orchestrator
We never create VMs manually. We use industry-standard orchestrators to define your datacenter in a simple config file:
- AWS ParallelCluster: Python-based CLI for Slurm on AWS.
- Azure CycleCloud: Visual GUI for enterprise cost management.
- Terraform: Multi-cloud infrastructure as code.
HPC Cloud-Native Innovations
Spot Instances
Purchase spare capacity at up to 90% discount. We implement Slurm Requeueing so your job automatically resumes if a node is reclaimed by the provider.
EFA & InfiniBand
Cloud networks are often too slow for MPI. We select specialized instance types (e.g., AWS hpc6a) with Elastic Fabric Adapter (EFA) for low-latency scaling.
