Fixed

rocSOLVER 3.15.0 for ROCm 4.5.2

rocSOLVER code for ROCm 4.5.2 is unchanged from rocSOLVER for ROCm 4.5.0. The library was rebuilt for the updated ROCm 4.5.2 stack.

  • HEGVD (with batched and strided_batched versions)
• Added --mem_query option to rocsolver-bench, which will print the amount of device memory required
  by a function.
• Added --profile option to rocsolver-bench, which will print profile logging results for a function.
• RQ factorization routines:
  • GERQ2, GERQF (with batched and strided_batched versions)

Optimized

• Improved performance of LU factorization (especially for large matrix sizes)

Changed

• The -h option of install.sh now prints a help message, instead of doing nothing.
• libfmt 7.1 is now a dependency
• Raised minimum requirement for building rocSOLVER from source to CMake 3.13
• Raised reference LAPACK version used for rocSOLVER test and benchmark clients to v3.9.1
• Minor CMake improvements for users building from source without install.sh:
  • Removed fmt::fmt from rocsolver's public usage requirements
  • Enabled small-size optimizations by default
• Split packaging into a runtime package ('rocsolver') and a development package ('rocsolver-devel').
  The development package depends on the runtime package. To aid in the transition, the runtime
  package suggests the development package (except on CentOS 7). This use of the suggests feature
  is deprecated and will be removed in a future ROCm release.

Fixed

• Use of the GCC / Clang __attribute__((deprecated(...))) extension is now guarded by compiler
  detection macros.

rocSOLVER 3.13.0 for ROCm 4.3.1

No changes made for ROCm 4.3.1.

rocSOLVER 3.13.0 for ROCm 4.3.0

Added

• Linear solvers for general non-square systems:
  • GELS now supports underdetermined and transposed cases
• Inverse of triangular matrices
  • TRTRI (with batched and strided_batched versions)
• Out-of-place general matrix inversion
  • GETRI_OUTOFPLACE (with batched and strided_batched versions)

Optimizations

• Improved general performance of matrix inversion (GETRI)

Changed

• Argument names for the benchmark client now match argument names from the public API

Removed

Fixed

• Fixed known issues with Thin-SVD. The problem was identified in the test specification, not in the thin-SVD
  implementation or the rocBLAS gemm_batched routines.
• Benchmark client will no longer crash as a result of leading dimension or stride arguments not being provided
  on the command line.

Known Issues

• Added rocblas to the dependency list of the rocsolver deb and rpm packages

Known Issues

• Thin-SVD implementation is failing in some cases (in particular m=300, n=120) due to a possible bug in the gemm_batched routines of rocBLAS.

  • STERF, STEQR
• Linear solvers for general non-square systems:
  • GELS (API added with batched and strided_batched versions. Only the overdetermined
    non-transpose case is implemented in this release. Other cases will return

• Eliminated a small memory transfer that was being done on the default stream
• Fixed GESVD right singular vectors for 1x1 matrices
