[petsc-users] PETSC3.2 and MUMPS 4.10.0 slower than PETSC3.1 and MUMPS 4.9.2

[Andreas Hauffe]

Hi,

during a timing test I noticed that PETSC3.2/MUMPS4.10.0 takes twice the time 
to solve a linear system compared to PETSC3.1/MUMPS4.9.2. In both cases I use 
the same configure options to compile PETSC and the MUMPS was downloaded 
during the compilation of PETSC. Did someone else get such a difference for 
the calculation time or can someone tell me what happens?
