If the dense matrix is on SSDs, the operation should be able to load the dense matrix or part of the dense matrix in memory and perform computation.

Lots of errors like this:
```

The MueLu timer summary (which uses Teuchos timers) at the end of drekar is wrong. Neither the Setup nor Ac times include the matrix-matrix multiply time. This is likely due to OpenMP threading and …

When ACCELERATION is 10, we seem able to accelerate up to our target speed without fail. When ACCELERATION is 100 or more, our maximum speed is much lower than the target speed and is spiky.
Here's …

In Tpetra, we need to isolate the "local" part of the sparse matrix-matrix multiply kernel from the "global" (MPI communication) part. This will facili…

What steps will reproduce the problem?
1. Apply the smoothed_aggregation preconditioner to a big enough matrix.
What is the expected output? What do you see instead?
The solver fails with bad::al…
