It has the same interface as the hybrid (CPU+GPU) implementation provided by magma_Xgetrf_gpu. Testing the performance of this routine is possible through running testing_Xgetrf_gpu with the option (--version 3)
• New routine: magma_Xpotrf_native (X = {s, d, c, z}) performs the Cholesky factorization using the GPU only. It has the same interface as the hybrid (CPU+GPU) implementation provided by magma_Xpotrf_gpu. Testing the performance of this routine is possible through running testing_Xpotrf_gpu with the option (--version 2)

Release Notes

• Added constrained least squares routines (magma_[sdcz]gglse) and dependencies:
  • magma_zggrqf - generalized RQ factorization

• Fixed some compilation issues with inf, nan, and nullptr.

MAGMA-sparse

• Changed the way how data from an external application is handled: There is now a clear distinction between memory allocated/used/freed from MAGMA and the user application. We added a functions magma_zvcopy and magma_zvpass that do not allocate memory, instead they copy values from/to application-allocated memory.
• The examples ( in example/example_sparse.c ) give a demonstration on how these routines should be used.

Release Notes

• Fix bugs in [zcsd]hegst[_gpu].cpp
• Fix a bug in [zcsd]latrd.cpp
• Fix a bug in [zcsd]gelqf_gpu.cpp
• Added application of a block reflector H or its transpose from the Right.
  • Routines changed -- [zcsd]larfb_gpu.cpp, [zc]unmqr2_gpu.cpp, and [ds]ormqr2_gpu.cpp
• Fix *larfb_gpu for reflector vectors stored row-wise.
• Fix memory allocation bugs in [zc]unmqr2_gpu.cpp, [ds]ormqr2_gpu.cpp, [zc]unmqr.cpp, and [ds]ormqr.cpp (thanks to Azzam Haidar).
• Fix bug in *lacpy that overwrote memory.
• Fix residual formula in testing_*gesv* and testing_*posv*.
• Fix sizeptr.cpp compile warning that caused make to fail.
• Fix warning in *getrf.cpp when nb0 is zero.
• Add reduction to band-diagonal for symmetric/Hermitian definite matrices in [zc]hebbd.cpp and [ds]sybbd.cpp
• Updated eigensolvers for standard and generalized eigenproblems for symmetric/Hermitian definite matrices
• Add wrappers around CUDA and CUBLAS functions, for portability and error checking.
• Add tracing functions.
• Add two-stage reduction to tridiabonal form
• Add matrix print functions.
• Make info and return codes consistent.
• Change GPU_TARGET in make.inc to descriptive name (e.g., Fermi).
• Move magma_stream to -lmagmablas to eliminate dependency on -lmagma.

• Fix a bug in [zcsd]gehrd for ilo > 1 or ihi < n.
• Added missing Fortran interfaces
• Add general matrix inverse, [zcds]getri GPU interface.
• Add [zcds]potri in CPU and GPU interfaces [Hatem Ltaief et al.]
