Thank you for your hard work at the MAGMA,and I'm intended to know that when the MAGMA can provide support for windows.
My system platform is Windows.
Thanks

Re: MAGMA 1.0
MAGMA 1.0 RC5 is now out.
This is the final release candidate before the final MAGMA 1.0 release. Any input it appreciated.

Re: MAGMA 1.0
I am about to dive in to the new RC5. Is there a list online of the new changes in RC5?
Thanks,
Jeremiah

Re: MAGMA 1.0
I added a ReleaseNotes file in the tarball to report the new changes. Here are the one since the last RC4:
1.0.0RC5  April 6th, 2011
* Add fortran interface for lapack functions
* Add new QR version on GPU ([zcsd]geqrf3_gpu) and corresponding
LS solver ([zcds]geqrs3_gpu)
* Add [cz]unmtr, [sd]ormtr functions
* Add two functions in fortran to compute the offset on device pointers
magmaf_[sdcz]off1d( NewPtr, OldPtr, inc, i)
magmaf_[sdcz]off2d( NewPtr, OldPtr, lda, i, j)
indices are given in Fortran (1 to N)
* WARNING: add FOPTS variable to the make.inc to use preprocessing
in compilation of Fortran files
* WARNING: fix bug with fortran compilers which don;t change the name
now fortran prefix is magmaf instead of magma
* Small documentation fixes
* Fix timing under windows, thanks to Evan Lazar
* Fix problem when __func__ is not present, thanks to Evan Lazar
* Fix bug with m==n==0 in LU, thanks to Evan Lazar
* Fix bug on [cz]unmqr, [sd]ormqr functions
* Fix bug in [zcsd]gebrd; fixes bug in SVD for n>m
* Fix bug in [zcsd]geqrs_gpu for multiple RHS
* Added functionality  zcgesv_gpu and dsgesv_gpu can now solve also
A' X = B using mixedprecision iterative refinement
* Fix error code in testings.h to compile with cuda 4.0

Re: MAGMA 1.0
I am new to magma, but couldn't find any implementations of syrk. Have I missed something? syrk is very important for things like regression.
Re: MAGMA 1.0
See CUBLAS, provided by NVIDIA. It implements all BLAS level 1, 2, 3 functions, including syrk. The MAGMA BLAS library only supplements CUBLAS when we need functionality not covered by BLAS (e.g., LACPY) or we develop a faster implementation.
