Does LAM need to be booted to compile LAM programs?
No. The compilation of LAM programs is completely independant of the run-time environment necessary for running LAM/MPI programs. [ Top of page | Return to FAQ ] 5. Do I need to install LAM on all nodes in my cluster? Short answer: yes. More complicated answer: LAM needs to be available on all nodes in your cluster. You can do this by physically installing LAM on all nodes in your cluster or by using a networked filesystem to make a single LAM installation available on all nodes in the cluster. See the FAQ question “Do I need a common filesystem on all my nodes?” for more details on this method. [ Top of page | Return to FAQ ] 6. Do I have to use the same version of LAM/MPI everywhere? YES!! Things change between versions of LAM/MPI — different versions of LAM/MPI do not play well with each other. LAM/MPI is intended to be source code compatible with a user application between multiple versions of LAM/MPI — no other guarantees are provided. That is, the MPI API is fixed and will not
