What’s New:

• Added a new API, cudaGraphNodeSetEnabled(), to allow disabling nodes in an instantiated graph. Support is limited to kernel nodes in this release. A corresponding API, cudaGraphNodeGetEnabled(), allows querying the enabled state of a node.
• Full release of 128-bit integer (__int128) data type including compiler and developer tools support. The host-side compiler must support the __int128 type to use this feature.
• Added ability to disable NULL kernel graph node launches.
• Added new NVML public APIs for querying functionality under Wayland.
• Added L2 cache control descriptors for atomics.
• Large CPU page support for UVM managed memory.

1.3. CUDA Compilers

11.6

• VS2022 Support: CUDA 11.6 officially supports the latest VS2022 as host compiler. A separate Nsight Visual Studio installer 2022.1.1 must be downloaded from here. A future CUDA release will have the Nsight Visual Studio installer with VS2022 support integrated into it.
• New instructions in public PTX: New instructions for bit mask creation — BMSK and sign extension — SZEXT are added to the public PTX ISA. You can find documentation for these instructions in the PTX ISA guide: BMSK and SZEXT.
• Unused Kernel Optimization: In CUDA 11.5, unused kernel pruning was introduced with the potential benefits of reducing binary size and improving performance through more efficient optimizations. This was an opt-in feature but in 11.6, this feature is enabled by default. As mentioned in the 11.5 blog here, there is an opt-out flag that can be used in case it becomes necessary for debug purposes or for other special situations.
• $ nvcc -rdc=true user.cu testlib.a -o user -Xnvlink -ignore-host-info
• In addition to the -arch=all and -arch=all-major options added in CUDA 11.5, NVCC introduced -arch= native in CUDA 11.5 update1. This -arch=native option is a convenient way for users to let NVCC determine the right target architecture to compile the CUDA device code to based on the GPU installed on the system. This can be particularly helpful for testing when applications are run on the same system they are compiled in.
• Generate PTX from nvlink: Using the following command line, device linker, nvlink will produce PTX as an output in addition to CUBIN:
• nvcc -dlto -dlink -ptx
• Device linking by nvlink is the final stage in the CUDA compilation process. Applications that have multiple source translation units have to be compiled in separate compilation mode. LTO (introduced in CUDA 11.4) allowed nvlink to perform optimizations at device link time instead of at compile time so that separately compiled applications with several translation units can be optimized to the same level as whole program compilations with a single translation unit. However, without the option to output PTX, applications that cared about forward compatibility of device code could not benefit from Link Time Optimization or had to constrain the device code to a single source file.
• With the option for nvlink that performs LTO to generate the output in PTX, customer applications that require forward compatibility across GPU architectures can span across multiple files and can also take advantage of Link Time Optimization.
• Bullseye support: NVCC compiled source code will work with code coverage tool Bullseye. The code coverage is only for the CPU or the host functions. Code coverage for device function is not supported through bullseye.
• INT128 developer tool support: In 11.5, CUDA C++ support for 128-bit was added. In this release, developer tools supports the datatype as well. With the latest version of libcu++, int 128 data type is supported by math functions.

cuSOLVER

New Features:

• New singular value decomposition (GESVDR) is added. GESVDR computes partial spectrum with random sampling, an order of magnitude faster than GESVD.
• libcusolver.so no longer links libcublas_static.a; instead, it depends on libcublas.so. This reduces the binary size of libcusolver.so. However, it breaks backward compatibility. The user has to link libcusolver.so with the correct version of libcublas.so.

cuSPARSE

New Features:

• New Tensor Core-accelerated Block Sparse Matrix — Matrix Multiplication (cusparseSpMM) and introduction of the Blocked-Ellpack storage format.
• New algorithms for CSR/COO Sparse Matrix — Vector Multiplication (cusparseSpMV) with better performance.
• Extended functionalities for cusparseSpMV:
• Support for the CSC format.
• Support for regular/complex bfloat16 data types for both uniform and mixed-precision computation.
• Support for mixed regular-complex data type computation.
• Support for deterministic and non-deterministic computation.
• New algorithm (CUSPARSE_SPMM_CSR_ALG3) for Sparse Matrix — Matrix Multiplication (cusparseSpMM) with better performance especially for small matrices.
• New routine for Sampled Dense Matrix — Dense Matrix Multiplication (cusparseSDDMM) which deprecated cusparseConstrainedGeMM and provides better performance.
• Better accuracy of cusparseAxpby, cusparseRot, cusparseSpVV for bfloat16 and half regular/complex data types.
• All routines support NVTX annotation for enhancing the profiler time line on complex applications.

Deprecations:

• cusparseConstrainedGeMM has been deprecated in favor of cusparseSDDMM.
• cusparseCsrmvEx has been deprecated in favor of cusparseSpMV.
• COO Array of Structure (CooAoS) format has been deprecated including cusparseCreateCooAoS, cusparseCooAoSGet, and its support for cusparseSpMV.

Known Issues:

• cusparseDestroySpVec, cusparseDestroyDnVec, cusparseDestroySpMat, cusparseDestroyDnMat, cusparseDestroy with NULL argument could cause segmentation fault on Windows.

Resolved Issues:

• cusparseAxpby, cusparseGather, cusparseScatter, cusparseRot, cusparseSpVV, cusparseSpMV now support zero-size matrices.
• cusparseCsr2cscEx2 now correctly handles empty matrices (nnz = 0).
• cusparseXcsr2csr_compress now uses 2-norm for the comparison of complex values instead of only the real part.
• NPPNew features:New APIs added to compute Distance Transform using Parallel Banding Algorithm (PBA):
• nppiDistanceTransformPBA_xxxxx_C1R_Ctx() — where xxxxx specifies the input and output combination: 8u16u, 8s16u, 16u16u, 16s16u, 8u32f, 8s32f, 16u32f, 16s32f
• nppiSignedDistanceTransformPBA_32f_C1R_Ctx()

Resolved issues:

• Fixed the issue in which Label Markers adds zero pixel as object region.
• NVJPEG

New Features:

• nvJPEG decoder added a new API to support region of interest (ROI) based decoding for batched hardware decoder:
• nvjpegDecodeBatchedEx()
• nvjpegDecodeBatchedSupportedEx()

cuFFTKnown Issues:

• cuFFT planning and plan estimation functions may not restore correct context affecting CUDA driver API applications.
• Plans with strides, primes larger than 127 in FFT size decomposition and total size of transform including strides bigger than 32GB produce incorrect results.

Resolved Issues:

• Previously, reduced performance of power-of-2 single precision FFTs was observed on GPUs with sm_86 architecture. This issue has been resolved.
• Large prime factors in size decomposition and real to complex or complex to real FFT type no longer cause cuFFT plan functions to fail.
• CUPTIDeprecations early notice:The following functions are scheduled to be deprecated in 11.3 and will be removed in a future release:
• NVPW_MetricsContext_RunScript and NVPW_MetricsContext_ExecScript_Begin from the header nvperf_host.h.
• cuptiDeviceGetTimestamp from the header cupti_events.h
