Dear ViennaCL users,
ViennaCL 1.5.2 is now available for download at
http://viennacl.sourceforge.net/
While the work for the upcoming 1.6.0 release is in full progress, this
maintenance release fixes a couple of bugs and performance regressions
reported to us:
- Fixed compilation problems on Visual Studio for the operations y +=
prod(A, x) and y -= prod(A, x) with dense matrix A.
- Added a better performance profile for NVIDIA Kepler GPUs. For
example, this increases the performance of matrix-matrix multiplications
to 600 GFLOPs in single precision on a GeForce GTX 680. Thanks to Paul
Dufort for bringing this to our attention.
- Added support for the operation A = trans(B) for matrices A and B to
the scheduler.
- Fixed compilation problems in block-ILU preconditioners when passing
block boundaries manually.
- Ensured compatibility with OpenCL 1.0, which may still be available
on older devices.
Thanks a lot for the precious feedback!
Best regards,
Karl Rupp
