So my questions here are (i) Did this issue ever happened for other deal.II
applications, how to solve it expect increase the number of nodes or memory

experts are using to dress memory issue. Should I build Valgrind by myself?
Does Valgrind only support MPI 2, my openMPI is v.3.
Valgrind doesn't care.
6.5*10^5 unknowns with a quadratic element in 3d can probably be expected to
take in the range of 2-5 GB. That should fit into most machines. But at the
same time, this is a small enough problem that you can run it under valgrind's
memory profilers on any workstation or laptop you have access to. You could
also talk to the system administrators of the cluster you work on to see
whether they are willing to give you a more up to date version of valgrind.
