Timeseries Analysis Tools

The programs are written in Fortran 90 and uses OpenMP for parallisation

.

Installation instructions

Using existing installation at SAC, Aarhus University

If you are and have access to the computer systems here, the easiest way to use the programs is simply to use the pre-compiled binaries available on the systems.

/usr/users/f041080/tidsserie/bin/machine

where machine is the system you are running on.

If you wish the program to use all available CPU cores available on your machine (and why wouldn't you?), you need to edit the file ~/.bashrc or ~/.cshrc (depending on which shell you use) and add the following line:

setenv OMP_NUM_THREADS 8 (csh, tcsh)
export OMP_NUM_THREADS=8 (bash)

The entire setup for the computer "ast", with 8 CPU cores, would for example look like this (in bash):

export PATH=$PATH:/usr/users/f041080/tidsserie/bin/ast
export OMP_NUM_THREADS=8

If you have any questions, feel free to ask me.

Compiling it yourself

First of all, you should send me an e-mail. Then I will grant you access to the SVN repository where the code is stored, and you should then be able to check out the code from the repo. using the following command:

svn checkout https://xp-dev.com/svn/TimeseriesTools .

make; make install

This will compile the program (by default using gfortran) and put the compiled binaries into the "bin" directory. If you wish to use a different compiler, you can simply modify the file "makefile.preample" where you can specify which compiler (and settings) to use.
