# EGLSync_CUDAEvent_Interop - EGLSync CUDA Event Interop

## Description

Demonstrates interoperability between CUDA Event and EGL Sync/EGL Image using which one can achieve synchronization on GPU itself for GL-EGL-CUDA operations instead of blocking CPU for synchronization.

## Key Concepts

EGLSync-CUDAEvent Interop, EGLImage-CUDA Interop
