You mean a plain `./configure && make && make install`, hence installed at the standard location as root?</i>

Well i mean that actually , but as non-root. And in the user folder
as in /home/<username>/mpich-install .

<pre wrap="">expect the part when i test the installation. The first test run : mpiexec -n <number> ./examples/cpi , went as planned but then the second test run on multiple nodes (mpiexec -f machinefile -n <number> ./examples/cpi) returned some errors. As the readme states there should be a machinefile. The thing is i cant find this file and tried to create it my self in the given form, just using only my laptops hostname a couple of times and placing it in the mpich installation directory ( /home/<username>/mpich-install) and that didnt fix the errors.

Is MPICH 3.0.4 also available on both machines?</i>

For now i have only this machine.Single laptop and i would like to
run some mpi programs. Maybe in this case , perhaps is the
machinefile useless??<br>

<pre wrap="">One other thing i noticed is that on the readme states that hydra is the primary process manager, but using the mpiexec -info it clearly states that pmi ( or something similar ) is the primary pm.

<i>Maybe it should better read: "Process Manager uses: pmi", and as the default is to compile Hydra, you know it already (there are different `mpiexec`s for the different process managers and e.g. mpiexec.gforker has no "-info" option).</i>

So the primary processor manager (default) in my installation is
hydra right?<br>

<pre wrap="">And for a last thing my installation was made without using any prefixes at the configuration.
PS.One other thing i just noticed is that when i did the installation i could run mpich ( the test runs with the pi programm, mpiexec -info , etc) , but now after a reboot i cant run mpich on the terminal. For example mpiexec -info returns bash: mpiexec: command not found . Whats the deal with that? Didnt i installed mpich on my machine?

<i>Might be a $PATH problem, in case it wasn't installed at the default location.</i></pre>

I thought of that too, and i checked it but unsuccessfully. Maybe it
has to do with the fact that i didn't installed it as root.Maybe i
need to redo the installation as root? Any suggestions? As to the
install location etc ?<br>
