# What\'s New in This Release
## AOMP ENHANCEMENTS
## Hipfort-Interface for GPU Kernel Libraries
AOMP is a scripted build of LLVM. It supports OpenMP target offload on AMD GPUs. Since AOMP is a Clang/LLVM compiler, it also supports GPU offloading with HIP, CUDA, and OpenCL.
Hipfort is an interface library for accessing GPU Kernels. It provides support to the AMD ROCm architecture from within the Fortran programming language. Currently, the gfortran and HIP-Clang compilers support hipfort. Note, the gfortran compiler belongs to the GNU Compiler Collection (GCC). While hipfc wrapper calls hipcc for the non-fortran kernel source, gfortran is used for FORTRAN applications that call GPU kernels.
The following enhancements are made for AOMP in this release:
* OpenMP 5.0 is enabled by default. You can use -fopenmp-version=45 for OpenMP 4.5 compliance
* Restructured to include the ROCm compiler
* B=Bitcode search path using hip policy HIP_DEVICE_LIB_PATH and hip-devic-lib command line option to enable global_free for kmpc_impl_free
The hipfort interface library is meant for Fortran developers with a focus on gfortran users.
Restructured hostrpc, including:
* Replaced hostcall register functions with handlePayload(service, payload). Note, handlPayload has a simple switch to call the correct service handler function.
* Removed the WITH_HSA macro
* Moved the hostrpc stubs and host fallback functions into a single library and the include file. This enables the stubs openmp cpp source instead of hip and reorganizes the directory openmp/libomptarget/hostrpc.
* Moved hostrpc_invoke.cl to DeviceRTLs/amdgcn.
* Generalized the vargs processing in printf to work for any vargs function to execute on the host, including a vargs function that uses a function pointer.
* Reorganized files, added global_allocate and global_free.
* Fixed llvm TypeID enum to match the current upstream llvm TypeID.
* Moved strlen_max function inside the declare target #ifdef _DEVICE_GPU in hostrpc.cpp to resolve linker failure seen in pfspecifier_str smoke test.
* Fixed AOMP_GIT_CHECK_BRANCH in aomp_common_vars to not block builds in Red Hat if the repository is on a specific commit hash.
* Simplified and reduced the size of openmp host runtime
* Switched to default OpenMP 5.0

## ROCm Data Center Tool
## ROCm COMMUNICATIONS COLLECTIVE LIBRARY
The ROCm™ Data Center Tool™ simplifies the administration and addresses key infrastructure challenges in AMD GPUs in cluster and datacenter environments. The important features of this tool are:
### Compatibility with NVIDIA Communications Collective Library v2\.7 API
* GPU telemetry
ROCm Communications Collective Library (RCCL) is now compatible with the NVIDIA Communications Collective Library (NCCL) v2.7 API.
* GPU statistics for jobs
RCCL (pronounced "Rickle") is a stand-alone library of standard collective communication routines for GPUs, implementing all-reduce, all-gather, reduce, broadcast, reduce-scatter, gather, scatter, and all-to-all. There is also initial support for direct GPU-to-GPU send and receive operations. It has been optimized to achieve high bandwidth on platforms using PCIe, xGMI as well as networking using InfiniBand Verbs or TCP/IP sockets. RCCL supports an arbitrary number of GPUs installed in a single node or multiple nodes, and can be used in either single- or multi-process (e.g., MPI) applications.
* Integration with third-party tools
The collective operations are implemented using ring and tree algorithms and have been optimized for throughput and latency. For best performance, small operations can be either batched into larger operations or aggregated through the API.
* Open source
For more information about RCCL APIs and compatibility with NCCL v2.7, see
https://rccl.readthedocs.io/en/develop/index.html
The ROCm Data Center Tool can be used in the standalone mode if all components are installed. The same set of features is also available in a library format that can be used by existing management tools.

## Singular Value Decomposition of Bi\-diagonal Matrices
Refer to the ROCm Data Center Tool™ User Guide for more details on the different modes of operation.
Rocsolver_bdsqr now computes the Singular Value Decomposition (SVD) of bi-diagonal matrices. It is an auxiliary function for the SVD of general matrices (function rocsolver_gesvd).
NOTE: The ROCm Data Center User Guide is intended to provide an overview of ROCm Data Center Tool features and how system administrators and Data Center (or HPC) users can administer and configure AMD GPUs. The guide also provides an overview of its components and open source developer handbook.
BDSQR computes the singular value decomposition (SVD) of a n-by-n bidiagonal matrix B.
For installation information on different distributions, refer to the ROCm Data Center User Guide at
The SVD of B has the following form:
B = Ub * S * Vb'
where
• S is the n-by-n diagonal matrix of singular values of B
• the columns of Ub are the left singular vectors of B
• the columns of Vb are its right singular vectors
The computation of the singular vectors is optional; this function accepts input matrices U (of size nu-by-n) and V (of size n-by-nv) that are overwritten with U*Ub and Vb*V. If nu = 0 no left vectors are computed; if nv = 0 no right vectors are computed.
Optionally, this function can also compute Ub*C for a given n-by-nc input matrix C.
PARAMETERS

• [in] uplo: rocblas_fill.
Specifies whether B is upper or lower bidiagonal.
• [in] n: rocblas_int. n >= 0.

• [inout] E: pointer to real type. Array on the GPU of dimension n-1.
On entry, the off-diagonal elements of B. On exit, if info > 0, the off-diagonal elements of a bidiagonal matrix orthogonally equivalent to B (if info = 0 this matrix converges to zero).
• [inout] V: pointer to type. Array on the GPU of dimension ldv*nv.
On entry, the matrix V. On exit, it is overwritten with Vb*V. (Not referenced if nv = 0).
• [in] ldv: rocblas_int. ldv >= n if nv > 0, or ldv >=1 if nv = 0.
Specifies the leading dimension of V.
• [inout] U: pointer to type. Array on the GPU of dimension ldu*n.
On entry, the matrix U. On exit, it is overwritten with U*Ub. (Not referenced if nu = 0).
• [in] ldu: rocblas_int. ldu >= nu.
Specifies the leading dimension of U.

### rocSPARSE_gemmi\() Operations for Sparse Matrices
### Error Correcting Code Fields in ROCm Data Center Tool
This enhancement provides a dense matrix sparse matrix multiplication using the CSR storage format.
rocsparse_gemmi multiplies the scalar αα with a dense m×km×k matrix AA and the sparse k×nk×n matrix BB defined in the CSR storage format, and adds the result to the dense m×nm×n matrix CC that is multiplied by the scalar ββ, such that
C:=α⋅op(A)⋅op(B)+β⋅CC:=α⋅op(A)⋅op(B)+β⋅C
with
The ROCm Data Center (RDC) tool is enhanced to provide counters to track correctable and uncorrectable errors. While a single bit per word error can be corrected, double bit per word errors cannot be corrected.
op(A)=⎧⎩⎨⎪⎪A,AT,AH,if trans_A == rocsparse_operation_noneif trans_A == rocsparse_operation_transposeif trans_A == rocsparse_operation_conjugate_transposeop(A)={A,if trans_A == rocsparse_operation_noneAT,if trans_A == rocsparse_operation_transposeAH,if trans_A == rocsparse_operation_conjugate_transpose
The RDC tool now helps monitor and protect undetected memory data corruption. If the system is using ECC- enabled memory, the ROCm Data Center tool can report the error counters to monitor the status of the memory.

Note: This function is non-blocking and executed asynchronously with the host. It may return before the actual computation has finished.
## Static Linking Libraries
For more information and examples, see
https://rocsparse.readthedocs.io/en/master/usermanual.html#rocsparse-gemmi
The underlying libraries of AMD ROCm are dynamic and are called shared objects (.so) in Linux.
The AMD ROCm v3.8 release includes the capability to build static ROCm libraries and link to the applications statically. CMake target files enable linking an application statically to ROCm libraries and each component exports the required dependencies for linking. The static libraries are called Archives (.a) in Linux.
This release also comprises of the requisite changes required for all the components to work in a static environment. The components have been successfully tested for basic functionalities like *rocminfo /rocm_bandwidth_test* and archives.
In the AMD ROCm v3.8 release, the following libraries support static linking:

# Fixed Defects
The following defects are fixed in this release:
* GPU Kernel C++ Names Not Demangled
* MIGraphX Fails for fp16 Datatype
* Issue with Peer-to-Peer Transfers
* rocprof option --parallel-kernels Not Supported in this Release
# Known Issues
The following are the known issues in this release.
## (AOMP) Undefined Hidden Symbol Linker Error Causes Compilation Failure in HIP
## Undefined Reference Issue in Statically Linked Libraries
The HIP example device_lib fails to compile due to unreferenced symbols with Link Time Optimization resulting in undefined hidden symbol errors.
Libraries and applications statically linked using flags -rtlib=compiler-rt, such as rocBLAS, have an implicit dependency on gcc_s not captured in their CMAKE configuration.
This issue is under investigation and there is no known workaround at this time.
Client applications may require linking with an additional library -lgcc_s to resolve the undefined reference to symbol '_Unwind_Resume@@GCC_3.0'.
## MIGraphX Pooling Operation Fails for Some Models
## MIGraphX Fails for fp16 Datatype
The MIGraphX functionality does not work for the fp16 datatype.
MIGraphX does not work for some models with pooling operations and the following error appears:
The following workaround is recommended:
*test_gpu_ops_test FAILED*
Use the AMD ROCm v3.3 of MIGraphX
This issue is currently under investigation and there is no known workaround currently.
Or
## MIVisionX Installation Error on CentOS/RHEL8.2 and SLES 15
Build MIGraphX v3.7 from the source using AMD ROCm v3.3
Installing ROCm on MIVisionX results in the following error on CentOS/RHEL8.2 and SLES 15:
## Missing Google Test Installation May Cause RCCL Unit Test Compilation Failure
Users of the RCCL install.sh script may encounter an RCCL unit test compilation error. It is recommended to use CMAKE directly instead of install.sh to compile RCCL. Ensure Google Test 1.10+ is available in the CMAKE search path.
As a workaround, use the latest RCCL from the GitHub development branch at:
https://github.com/ROCmSoftwarePlatform/rccl/pull/237
## Issue with Peer-to-Peer Transfers
Using peer-to-peer (P2P) transfers on systems without the hardware P2P assistance may produce incorrect results.
Ensure the hardware supports peer-to-peer transfers and enable the peer-to-peer setting in the hardware to resolve this issue.
## Partial Loss of Tracing Events for Large Applications
An internal tracing buffer allocation issue can cause a partial loss of some tracing events for large applications.
As a workaround, rebuild the roctracer/rocprofiler libraries from the GitHub roc-3.7 branch at:
• https://github.com/ROCm-Developer-Tools/rocprofiler
• https://github.com/ROCm-Developer-Tools/roctracer
## GPU Kernel C++ Names Not Demangled
GPU kernel C++ names in the profiling traces and stats produced by —hsa-trace option are not demangled.
As a workaround, users may choose to demangle the GPU kernel C++ names as required.
## rocprof option --parallel-kernels Not Supported in This Release
rocprof option --parallel-kernels is available in the options list, however, it is not fully validated and supported in this release.
## Random Soft Hang Observed When Running ResNet-Based Models
A random soft hang is observed when running ResNet-based models for a loop run of more than 25 to 30 hours. The issue is observed on both PyTorch and TensorFlow frameworks.
You can terminate the unresponsive process to temporarily resolve the issue.
There is no known workaround at this time.
*"Problem: nothing provides opencv needed"*
As a workaround, install opencv before installing MIVisionX.
