[petsc-users] Problem with mpiexec

[Konstantinos Kontzialis]

Dear all,

  I use Fedora 15 and I needed to make a new install of the system. 
However, when I installed petsc mpiexec did not work. Fedora 15 uses now 
mpich2-1.4.1 which uses hydra as the default process manager. But 
nothing is working. Any suggestions about what should I check and what 
to do?
