Hi all, Good day!
After installing ParaView on my desktop, PETSc starts to work anomalously even after reconfiguration: 1. If I use mpirun (frequently used before), it seems that now all the processors will run the program independently without communication. While mpiexec seems to work properly. 2. The Makefile (as attached) which works fine before starts to complain: make: *** No rule to make target 'chkopts', needed by 'test'. Stop. Thanks for your kind help! Best regards, Kai PETSC_DIR=~/petsc PETSC_ARCH=arch-linux-c-debug CFLAGS = -I. FFLAGS= CPPFLAGS=-I.
