[Trilinos-Users] trilinos and CUDA

Gianluca,

The Tpetra library of distributed linear algebra objects is currently being
refactored to supported multi-core/many-core shared memory nodes. The plan
is to support CUDA for Tpetra objects as well (rudimentary support is
already in place). By combining Tpetra with Trilinos's Belos linear solver
or Anasazi eigenvalue solver, this would provide the ability to run these
solvers mostly on the GPU (where "mostly" refers to the large
vector/multivector and matrix operations).

This capability may release with the next version of Trilinos in September.
I say may because our priority is multi-core CPUs before GPGPU. However,
most of our GPU implementations have been tested outside of Trilinos and are
waiting to be moved in.

Chris
