[petsc-dev] Fwd: ECP AHM breakout session on multiprecision

[Smith, Barry F.]

   Just received this email while responding to Jed's latest :-)

    I could say yes, but I'll have to ask for at least $100k to type ./configure --with-precision=single :-)

Dear Berry,

I am submitting a request for a breakout session at the ECP AHM next February on the topic multiprecision. I know you are very active in researching on solver technology for Exascale. Would you be interested in giving a 5-min short talk on multiprecision iterative solver efforts? Possible topics could be:
* reducing precision for certain components
* iterative refinement
* extended precision orthogonalization in Krylov solvers
* any other topics related to multiprecision efforts

Please feel free to suggest other people if you don't feel like.

Great thanks, Hartwig
