[petsc-users] GPUs, cud, complex

[Smith, Barry F.]

  Randy,

    Could you please cut and paste the entire error message you get. It worked for me. 

    I assume you mean -dm_mat_type aijcusparse  not aijcuda (which doesn't exist).

  Satish,

      I does appear we do not have a nightly test for cuda and complex, could that test be added to the nightly sweeps?

   Thanks

   Barry
