# 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
|
||||
|
||||
