I would bet a beer that Jed's Intel intrinsics beat the pants off of anything OSKI has to offer at this point. A On Fri, Apr 8, 2011 at 7:50 AM, Barry Smith <[email protected]> wrote:

Dear Sir or Madam,

There is such a configuration script, petsc-3.1-p8/config/PETSc/packages/oski.py, in the PETSc distribution. Does this mean that PETSc uses OSKI sparse matrix-vector routines? If yes, is it possible to use shared libraries? It is written as: self.liblist = [['oski/liboski_Tid.a','oski/liboski.a']] This means the libraries are static.

In fact I want to use benefits of OSKI together with my sparse matrix ordering tool, in a numerical method which can be performed by PETSc.

Yours Faithfully,

Kadir
