GPUs Advantages • Optimized for structured parallel execution • Extensive ALU counts & Memory Bandwidth • Cooperative multi-threading threading hides latency • Shared Instruction Resources • Fixed function units for parallel workloads dispatch • Extensive exploitation of Locality 38
GPUs Disadvantages Ineffective for Single threaded execution • Divergence • Parallelism lost opportunity • Loss of efficiency i • Upload/download of data cost •Requires large workload to fully utilize • Small Caches are optimized for locality/throughput 39
