MAGMA User

Welcome to the MAGMA User Forum.

http://icl.utk.edu/magma/

The MAGMA project aims to develop a dense linear algebra library similar to LAPACK but for heterogeneous/hybrid architectures, starting with current "Multicore+GPU" systems.

For bug reports, please file an issue on bitbucket. This helps us track the status.

https://bitbucket.org/icl/magma/issues

Note this MAGMA is different than the Magma Computational Algebra System. For help with that system, see http://magma.maths.usyd.edu.au/magma/
