## Release Notes
|
||||
|
||||
This section describes the release notes for the CUDA Samples on GitHub only.
|
||||
|
||||
### CUDA 11.3
|
||||
* Added `streamOrderedAllocationIPC`. Demonstrates Inter Process Communication using one process per GPU for computation.
|
||||
* Added `simpleCUBLAS_LU`. Demonstrates batched matrix LU decomposition using cuBLAS API `cublas<t>getrfBatched()`
|
||||
* Updated `simpleVulkan`. Demonstrates use of timeline semaphore.
|
||||
* Updated multiple samples to use pinned memory using `cudaMallocHost()`.
|
||||
|
||||
### CUDA 11.2
|
||||
* Added `streamOrderedAllocation`. Demonstrates stream ordered memory allocation on a GPU using cudaMallocAsync and cudaMemPool family of APIs.
|
||||
* Added `streamOrderedAllocationP2P`. Demonstrates peer-to-peer access of stream ordered memory allocated using cudaMallocAsync and cudaMemPool family of APIs.
