How are you measuring? What preconditioner are you using and how many
iterations are typically required?

Hey Matt,
Do you have any guidance or ideas regarding how large the subdomains
should be to offset the cost of this copy?
Cheers,

Hello everyone,
Can someone provide me advice on using OpenMP in PETSc? I am solving a
problem like this:
int main()
{
vec vsum;
for(i=0; i< N; i++)
{
vec vi;
fcomputev(i, vi);
VecAXPY(vsum, 1.0, vi); // vsum +=vi;
}
}
Can I use OpenMP "omp parallel for" to do the
I have a question about PetscBagCreate (the documentation for which can
be found here [1]).
The documentation says that the size of the struct cannot be larger than
a PetscInt, which is 4 bytes. Is this referring to the entire struct, or
just a pointer to it?
If the size of the struct itself c

You could send to petsc-maint instead (and / or try zipping)

Thanks, I get the idea now and changed the code to:
KSP *subksp;
