DDT for a serial job (no MPI): customize and run

When you launch AllineaTools DDT graphical interface, and establish connection with the cluster (if using a remote GUI client), proceed with “Run”:

Allinea DDT serial Run1


In the “Run (queue submission mode)” window, choose the application name, working directory, program arguments (if needed), an input file (if needed), check “Submit to Queue” (if needed), and then click “Run” :

Allinea DDT serial Run2


After your process starts on the cluster, it stops in the beginning of the program. You could then view the source code, choose breakpoints, watchpoints, tracepoints, etc. Click on “Run”/”Play” button (top left-hand corner) to proceed:

Allinea DDT serial Run3


Use the top navigation bar to add a breakpoint:

Allinea DDT Serial Run4 add a breakpoint


Choose the options:

Allinea DDT Serial Run5 add a breakpoint


… and run it:

Allinea DDT Serial Run6


You will get notified upon reaching the breakpoint:

Allinea DDT Serial Run7 breakpoint reached


You could then examine your variables:

Allinea DDT Serial Run8 check variables


… of different types:

Allinea DDT Serial Run9 - check variables


… and more variables:

Allinea DDT Serial Run10 - check variables


… some may not be readily available:
