Hello:
Two questions:
1. What does it mean to compile using the --with-purify option? is this an option i invoke when i call mpicc or do i need to activate this option somewhere else?
2. In the context of MPI, can someone please decipher what the following 2 memory leak errors mean? These are outputs from using VALGRIND:
