Solution Overview
Problem
Access to GPUs has become a major obstacle for users attempting to develop AI applications due to the growing demand outpacing supply, leading to uncertainty and inefficiency in accessing necessary compute resources.

The implementation of capacity cluster resource reservations in a cloud provider network, which allows users to reserve blocks of GPU time for specific durations, ensuring predictable access to GPUs without the need for long-term commitments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users access GPUs on-demand in a cloud provider network, then flexibility and ease of operation are improved, but access reliability and predictability deteriorate due to supply constraints and search time
Solution Approach 1:
The system performs preliminary actions by pre-launching auxiliary compute instances in the same execution slot before the main compute instance starts. These auxiliary instances pre-load machine images, hydrate boot volumes, and prepare the execution environment, so when the main instance needs to start, the infrastructure is already ready, eliminating search and setup time while ensuring predictable access.
Solution Approach 2:
The instance launch process is segmented into two independent parts: auxiliary instance operations (pre-loading, hydrating, preparing) and main instance operations (starting, executing). This segmentation allows the auxiliary instance to perform preparatory work without blocking the main instance's startup, improving both reliability and operational efficiency.
2Reliability
If capacity cluster resource reservations are implemented, then access predictability and reliability are improved, but device complexity and system overhead increase
Solution Approach 1:
The auxiliary compute instance serves multiple functions: it pre-loads machine images, hydrates boot volumes, performs health checks on physical resources, and prepares the execution slot. This multi-functionality reduces the need for separate systems for each task, managing complexity while improving reliability.
Solution Approach 2:
The auxiliary instance performs self-service operations by automatically preparing its own execution environment and validating resources without external intervention. This automation reduces operational complexity and ensures consistent, predictable resource availability.
3Speed
If auxiliary compute instances are launched in same-slot for pre-warming, then instance startup speed is improved, but resource utilization efficiency temporarily decreases
Solution Approach 1:
The auxiliary instance operates periodically - it is launched temporarily to perform pre-warming operations, then terminated. This periodic activation ensures resources are prepared only when needed, maintaining fast startup speeds while minimizing the time resources are occupied by auxiliary instances, thus preserving overall productivity.
Solution Approach 2:
The auxiliary instance performs preliminary actions (pre-loading, hydrating, health checks) before the main instance starts. By completing these tasks in advance, the system achieves fast instance startup without permanently allocating additional resources, as the auxiliary instance terminates after its preparatory work is done.
Data Source
AI summary
Techniques for implementing instance local boots in a cloud provider network via auxiliary domains are described. An auxiliary compute instance is launched and attached to a local storage device of the computing device. The auxiliary compute instance can pre-warm a boot volume by fetching its data from a remote system and storing the boot volume to the local storage device. The auxiliary compute instance is terminated, and a user compute device is launched into the same slot and connected to the local storage device. The user compute device utilizes the pre-warmed boot volume for launch.
