AI Data Centre

Trace governed data through storage, distributed training, validation and model inference.

01Introduction to Computer and System
Advanced infrastructure

AI requires a complete infrastructure pipeline

Accelerators are only one layer of an AI service; data, software, networking, operations and governance are equally important.

Training and inference

DimensionAI trainingAI inference
PurposeLearn model parameters from dataUse a trained model to produce outputs
WorkloadLarge repeated computations over datasetsRequests from users or applications
Hardware emphasisMany accelerators and fast interconnectsLatency, availability and efficient serving
StorageTraining data and checkpointsModel weights, cache and logs
Operational concernLong jobs, failure recovery and schedulingResponse time, scaling and reliability

Responsible operation

AI infrastructure must protect data, control access, monitor models, manage bias and consider the energy and water implications of computation.
