Dear Hong,
Thanks for your reply. In the modified mumps.c, I replaced zmumps_c.h with
cmumps_c.h because I want to use a single precision complex mumps in my
double-precision PETSC application.
In my PETSC application (double precision real and complex versions), I
want to always call a

The data types are defined as
s: single real
d: double real
c: single complex

Dear Barry and PETSC users,
I am revisiting a problem about how to call a single precision MUMPS from
double precision real/complex PETSC. After taking a look at mumps.c, I feel
that the following changes (attached) can make it possible to always call a
single precision MUMPS from PETSC. The
Dear PETSC users,
When MUMPS is used inside PETSC, The default MUMPS driver seems to be
double-precision MUMPS (i.e. DMUMPS). To reduce memory costs, I want to
test a single-precision MUMPS (SMUMPS) from PETSC. Does anyone know how to
switch from double to single-precision MUMPS inside PETSC? In
There is no support for this. You can only call single precision MUMPS from
single precision PETSc and double precision MUMPS from double precision PETSc.
You could try to hack the interface that calls MUMPS from PETSc to use the
single precision version but we don’t support that.
