GPU Cons Tips & Tricks

GPUs on servers expensive• CPU fallback for specific deployments

• Reach high and consistent GPU utilization

Difficult to reach high utilization

• CPU – GPU transfer (latency and

throughput)

• Many operations on small images

• Powerful DNNs to offload traditional algorithms

• Batch processing

• Parallel computations (pipelines & buffers)

Limited memory

• Unfortunately, often a tradeoff with parallel

computations

• Use spatial and temporal resolutions (pyramid)

GPU virtualization is difficult • Consider using on-demand cloud instances
