# CUDA Event Benchmarks
Simple benchmarks of `cudaEvent_t` APIs:
- `cudaEventCreate`
- `cudaEventRecord`
- `cudaEventQuery`
- `cudaStreamWaitEvent`
- `cudaEventDestroy`
- A simulated event pool that maintains a list of free events (more of a benchmark of `std::list`
push/pop for cost comparison to `cudaEventCreate`).
Each test is performed once using default-created events (support timing) and once with events that
do not support timing.
Here are the results from running with a single GPU (`CUDA_VISIBLE_DEVICES` is set to only that GPU)
of an NVIDIA DGX1 (with Tesla V100 GPUs with 32GB each).
- OS: `Ubuntu 18.04`.
- CUDA: `10.2`.
- NVIDIA Driver: `440.64.00`.
