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
