Hello,
I need a parallel block tridiagonal solver and thought PETSc would be
perfect. However, there seems to be no specific example showing exactly
which VecCreate and MatCreate functions to use. I searched the archive
and the web and there is no explicit block tridiagonal examples
Hi all,
I run my code as follows:
mpiexec -np 2 ./hoac test1.cgns
and I get the following error:
./hoac: error while loading shared libraries: libpetsc.so.3.11: cannot open
shared object file: No such file or directory
./hoac: error while loading shared libraries: libpetsc.so.3.11: cannot open
Where do your tridiagonal systems come from? Do you need to solve one
at a time, or batches of tridiagonal problems?
Although it is not in PETSc, we have some work on solving the sort of
tridiagonal systems that arise in compact discretizations, which it
turns out can be solved much faster than
