<div dir="ltr"><div>Is there a collection of utility routines used for interfacing to externalpackages? For example, I imagine that converting to different kinds of sparse formats is somewhat common. Or are the inputs to the externalpackages that PETSc interfaces with all so different that no such common routines exist?<br>
<br></div>The two external solvers I would like to create an interface for are WSMP and MKL's PARDISO. Has this been done?<br><div><br>Regards,<br>John<br><br></div></div>
