Thank you everyone for your valuable materials and comments.
Currently, I can use a maximum of 8 nodes on a computer system with a 10 Gb
InfiniBand network.
I am applying to use all the nodes in this computer system (about 300
nodes).
It will take some time.
I also hope 300 nodes are enough to

Hello Petsc developers and supporters,
I would like to confirm the performance of asynchronous computations of
inner product computation overlapping with matrix-vector multiplication
computation by the below code.
PetscLogDouble tt1,tt2;
KSP ksp;
//ierr = VecSet(c,one);
ierr =
