Good morning, My question is about getting the values of a parallel vector in the PETSc subroutines using Fortran 90.
As far as I know, I can invoke: CALL VecGetArrayF90 in order to get the full array that is being considered in each processor. However, I cannot employ this tool since I need to have also the values that are stored in other processors. Is there a straight way to get the value of the n-th element of a parallel vector, no matter where this element is stored? I am aware of the difficulty of this task, since it would involve transfer of information between different processors. Thanking you in advance, Jaime Suarez Theoretical and Computational Chemistry in Crete (TCCC), Institute of Electronic Structure and Laser (IESL), FOundation for Research and Technology-Hellas (FORTH)
