[petsc-users] Low floating precision numerical solver?

[Smith, Barry F.]

  Manuel,

    We don't have support for this yet for GPUs, it is on our list but not a priority, just utilizing GPUs well is our first priority.

    Note what the people who give these types of presentations forget to emphasis enough is that though this techniques for some algorithms can give good benefits on GPUs utilizing lower precision on CPUs doesn't generally benefit you much.
