At my home in a cluster, one people installed mpich2, then the mpicc address was modified to mpich2/bin/mpicc. I compiled the other mpich2 at my home with the other name “H”, when I write in terminal “which mpicc” the previous address is the address of mpicc. when I want to 'mae clean" the previous mpich2 it is not cleaned.
What should I do to clean the first one that when I write in terminal “which mpicc” I don’t see the previous one(*“mpich2/bin/mpicc”)?
Would you please help me?
