Running MPI on the Nordita linux cluster
No fortran90 compiler?
Just type (for linux):
wget -O - http://ftp.g95.org/g95-x86-linux.tgz | tar xvfz -
The same for a mac would be
wget -O - http://ftp.g95.org/g95-x86-osx.tgz | tar xvfz -
and then make sure the resulting executable is in your path, e.g.,
cd ~/bin; ln -s ~/g95-install/bin/i686-pc-linux-gnu-g95 g95

CVS for Windows (WinCVS)
Google for cvs, get WinCVS binary code, → Download Installer,
Install Python when asked to (or just ignore).
Click on the → Admin → Login buttons on the task bar,
fill in CVSROOT when asked to, e.g.
where $USER has to be substituted by a valid cvs user name.
You will then be asked for a directory name (you can generate a new
name here, e.g. NorditaCVS). After that it asks you for the password.
Click on the → Remote → Checkout buttons on the task bar,
to get the desired directory.
To ustall cvs on a mac, see
Axel's CVS repository
setenv CVSROOT :pserver:$USER@126.96.36.199:/var/cvs/brandenb
cvs co ap #(to get the astrophysics directory)
After you checked in changes, I will need to approve the changes
and update the changes.
If you run bash (check by saying "echo $SHELL"), say
and don't forget the colon here!
To set your correct editor, say *one* of the following:
setenv CVSEDIT vi
setenv CVSEDIT emacs
setenv CVSEDIT nano
If you are sitting on the Nordita network, cvs.nordita.dk is not interpreted
correctly. If this is a problem, try:
pc_cvs_chroot :pserver:$USER@cvs.nordita.dk:/var/cvs/brandenb :pserver:$USER@188.8.131.52:/var/cvs/brandenb
If your latex compilation complains about some missing inputs file, try
or, in tcsh, with even more useful stuff,
setenv TEXINPUTS .::$PENCIL_HOME/doc/texinputs//:$HOME/tex/inputs//:./texinputs:./fig:./figs:./png
This of course assumes that your $HOME/tex/inputs contains the missing files.
CVS/Latex editing practice
If you are writing papers with somebody else, and especially if those
papers are maintained under CVS, you want to minimize changes in the
layout connected with the wrapping of lines.
Even if you are not using CVS, the other person(s) want to check with
the diff command what has been changed, and it is frustrating to find
out that nothing has changed in the actual content.
So this means one should turn off automatic line wrapping, which seems
to be the default on some editors.
For the same reason it is advantageous to avoid very long lines
(longer than 80 characters).
If the other person happened to changed something in the same line, it
is then much easier to see what has happened, and how the changes should
It is also good editing practice in LaTeX to start each sentence on a new line.
This makes it also easier to rearrange the line of thought in a paper.
Of course, this does not change anything in the layout of the compiled
Our practice is that we add comments with our initials
between the old out-commented piece or line and the new one.
If a single change extends over more than one line, we have
an end comment line with a dot, e.g., %AB.
We would then remove our comments after the other relevant person
has read it and agreed with it, or put another comment and/or
another change instead.
