[petsc-users] cudaSetDevice

[Harshad Sahasrabudhe]

Hi Jed,

Sometime back we talked about an interface which could handle other
libraries calling cudaSetDevice simultaneously with PETSc. For example, in
our case 2 different instances of PETSc calling cudaSetDevice.

Do we already have any solution for this? If not, can we start looking at
this case?

Thanks,
Harshad
