Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The training of machine learning models has become increasingly resource-intensive and time-consuming due to the complexity of models and the size of datasets, with conventional technologies requiring manual specification of infrastructure-level resource configurations, leading to inefficiencies in hyperparameter tuning.
Innovation Solution
The technology automatically determines the best resource configuration for nodes in a distributed training environment, using a dual loop approach to optimize node arrangement and resource allocation, thereby accelerating the hyperparameter tuning process by intelligently pruning the search space of resource configurations.

1Ease of operation
If manual specification of resource configurations is used for distributed training, then flexibility and control over resource allocation are maintained, but the time and complexity of hyperparameter tuning increase significantly
Solution Approach 1:
The system performs self-service by automatically determining optimal resource configurations for distributed training without requiring manual specification. The orchestration platform autonomously analyzes training workloads, evaluates resource allocation options, and selects configurations that optimize training efficiency, thereby eliminating the time-consuming manual configuration process while maintaining operational flexibility.
Solution Approach 2:
The system dynamically changes resource configuration parameters based on the specific characteristics of the training workload. By automatically adjusting parameters such as the number of worker nodes, parameter server nodes, and resource allocation ratios, the system adapts to different hyperparameter tuning scenarios, reducing tuning time while preserving the ability to control resource allocation when needed.
2Manufacturing precision
If the search space of all resource configurations is exhaustively evaluated, then the optimal configuration is guaranteed to be found, but the computational time and resources required increase exponentially
Solution Approach 1:
The system performs preliminary actions by pre-evaluating and ranking resource configurations based on historical data and workload characteristics before actual training begins. The orchestration platform prepares a curated set of promising configurations in advance, eliminating the need to exhaustively evaluate all possible configurations during the actual hyperparameter tuning process, thus maintaining optimality while reducing evaluation time.
Solution Approach 2:
The system applies partial action by evaluating only a subset of the most promising resource configurations rather than the complete search space. By using heuristics and historical performance data to identify and focus on the most likely optimal configurations, the system achieves near-optimal results with significantly reduced evaluation time and computational resources.
3Productivity
If more computing resources are allocated to distributed training, then the speed of model training increases, but the cost and resource consumption increase proportionally
Solution Approach 1:
The system optimizes the ratio parameters between different types of computing resources (worker nodes vs. parameter server nodes). By dynamically adjusting these allocation ratios based on the specific training workload and model characteristics, the system achieves high training speed while minimizing total resource consumption, avoiding the linear relationship between resource allocation and cost.
Solution Approach 2:
The system implements feedback mechanisms that monitor training progress and resource utilization in real-time. Based on this feedback, the orchestration platform dynamically adjusts resource allocation to maintain optimal training speed while preventing excessive resource consumption, ensuring cost-effective high-performance training.

AI summary
Systems and methods can be configured to determine a plurality of computing resource configurations used to perform machine learning model training jobs. A computing resource configuration can comprise: a first tuple including numbers of worker nodes and parameter server nodes, and a second tuple including resource allocations for the worker nodes and parameter server nodes. At least one machine learning training job can be executed using a first computing resource configuration having a first set of values associated with the first tuple. During the executing the machine learning training job: resource usage of the worker nodes and parameter server nodes caused by a second set of values associated with the second tuple can be monitored, and whether to adjust the second set of values can be determined. Whether a stopping criterion is satisfied can be determined. One of the plurality of computing resource configurations can be selected.
