TAU Commander Initialize:
To begin Initialize TAU Commander, enter: tau initialize or simply
tau init.
This first initialization will take quite a bit of time. Not only is this
command creating a project it is also downloading and building the
TAU Performance System® and associated libraries that it depends on.
Let this run and check for successful completion. When it completes it will
display the tau dashboard (which can be viewed at anytime by entering:
‘tau dashboard’).
Many parameters may be defined at initialization. The full list of options is
displayed below this help section. It is easier to define options at
initialization (eg. tau init –MPI T) than it is to edit application and
measurement later.
