 - Q&A

-## MPI Environment Setup
-
-First, make sure you have access to Andorra. Then log in Andorra via `ssh`.
-
-Inside Andorra, you can try
-
-```bash
-ping compute <press Tab>
-```
-
-to show all the available computing nodes, which looks like this:
-
-```bash
-compute01                   compute05                   compute09
-compute01.imp.fu-berlin.de  compute05.imp.fu-berlin.de  compute09.imp.fu-berlin.de
-compute02                   compute06                   compute10
-compute02.imp.fu-berlin.de  compute06.imp.fu-berlin.de  compute10.imp.fu-berlin.de
-compute03                   compute07                   compute11
-compute03.imp.fu-berlin.de  compute07.imp.fu-berlin.de  compute11.imp.fu-berlin.de
-compute04                   compute08                   compute12
-compute04.imp.fu-berlin.de  compute08.imp.fu-berlin.de  compute12.imp.fu-berlin.de
-```
-
-You can then refer these nodes later using their names, such as `compute01`, `compute02` to execute your MPI programs.
-
-Now, log in one of these node within Andorra via `ssh`, for example `ssh compute01`. You might be required to input your password (from your ZEDAT account).
-
-After that, you are in the computing environment in which you can compile and run your MPI Program.
-
-You files on Andorra are synchronized among these nodes, so you can use them directly.
-
-### Example
-
-You can try to run the code examples provided by this repo.
-
-First, clone this repo on Andorra:
-
-```bash
-# via SSH
-git clone git@git.imp.fu-berlin.de:mactavish96/alp4-tutorials.git
-
-# via HTTP
-git clone https://git.imp.fu-berlin.de/mactavish96/alp4-tutorials.git
-```
-
-Then, log into one of these node, e.g. `ssh compute01`.
-
-Then, find your the git repo you just cloned and `cd <path to the repo>/exercises/MPI_examples/hello_world`
-
-And then, run `make` to compile the program.
-
-At last, run `mpirun -H compute01,compute02,compute03,compute04 ./hello_world` to execute your MPI program.
-
-You will see output like this:
-
-```bash
-compute01% mpirun -H compute01,compute02,compute03,compute04 ./hello_world
-Hello world, processor: compute01, rank: 0, total num of processors: 4
-Hello world, processor: compute03, rank: 2, total num of processors: 4
-Hello world, processor: compute04, rank: 3, total num of processors: 4
-Hello world, processor: compute02, rank: 1, total num of processors: 4
-```
