I have created a fresh conda environment and installed mpirun. However, which mpirun gives me /usr/bin/mpirun. Moreoever, I cannot find mpirun in ..../anaconda3/envs/env_name/bin/. Same goes for mpicxx or mpicc. Although I could see gcc and gxx in the anaconda bin. What's going on? How can I use the anaconda mpirun and others instead of the system packages?
Note that conda install -c conda-forge mpich works fine but conda install -c conda-forge mpich-mpicxx gets frozen.
Also note that echo -e ${PATH//:/\\n} shows conda path at the top.
Sorry for asking this basic question but I somehow mess this up while working on a remote cluster.
