[petsc-users] Postdoc Position at CU Boulder: High order discretization, multilevel methods, performance portability

CU Boulder Computer Science has an immediate opening for a postdoctoral researcher in the development of robust and efficient methods for high order/compatible PDE discretization and multilevel solvers, including deployment in open source libraries. The project is especially interested in

Re: [petsc-users] Problem with solving Poisson eqn for some cases

Run in the debugger and step/next through the code to see what code path it is taking and why it doesn't seem to follow the intended code path. > On Mar 26, 2018, at 7:10 AM, Matthew Knepley wrote: > > On Mon, Mar 26, 2018 at 1:15 AM, TAY wee-beng

Re: [petsc-users] KSP in common blocks

Unfortunately due to a "feature" of Fortran you can no longer store PETSc objects in common blocks; you can use modules, for example, if you need to access the objects from multiple routines without passing them as arguments. Barry We changed our examples to reflect this problem.

[petsc-users] KSP in common blocks

In upgrading to PETSc v3.8.x, we are seeing a compilation error with gfortran (version 6.2.0, users report the same problem with version 7.x).   The compile error is thrown when, say, type KSP variables are put in common blocks; we do not see any errors with this construct when using ifort
