Allinea Forge/DDT Client

I. Allinea DDT Client

The Client software is free from: https://www.allinea.com/products/forge/download#remote-client.

The version for matching with CADES’ server-end is 6.0.6 (Currently).

II. Configuration of Remote Server

Currently, CADES has 2 versions of Allinea DDT/Forge, the following is tested with v.6.0.6

II-1. Start Allinea Forge Client locally

Allinea Forge/DDT Client application installed ......

On your screen .......

II-2. Configure Remote Launching

Drop-down configure ......

Add or Modify ......

Remote Launch Settings......

AND, ......

II-3. DDT template on CADES

You have to configure a DDT template file, to be used by Allinea Forge Client, as following:

e.g., here a file named as ddt_template.qtf, which MUST be put in your home directory.

#
# Name: Generic Torque
#
# WARNING: If you install a new version of Allinea Forge to the same
#          directory as this installation, then this file will be overwritten.
#          If you customize this script at all, please rename it.
#
# submit: qsub
# display: qstat
# job regexp: (.+)
# cancel: qdel JOB_ID_TAG
# show num_nodes: yes
#
# WALL_CLOCK_LIMIT_TAG: {type=text,label="Wall Clock Limit",default="00:30:00",mask="09:09:09"}
# QUEUE_TAG: {type=text,label="Queue",default=debug}
## Allinea Forge will generate a submission script from this by
## replacing these tags:
##        TAG NAME         |         DESCRIPTION           |        EXAMPLE
## ---------------------------------------------------------------------------
## PROGRAM_TAG             | target path and filename      | /users/ned/a.out
## PROGRAM_ARGUMENTS_TAG   | arguments to target program   | -myarg myval
## NUM_PROCS_TAG           | total number of processes     | 16
## NUM_NODES_TAG           | number of compute nodes       | 8
## PROCS_PER_NODE_TAG      | processes per node            | 2
## NUM_THREADS_TAG         | OpenMP threads per proc       | 4
## DDT_DEBUGGER_ARGUMENTS_TAG | arguments to be passed to ddt-debugger
## MPIRUN_TAG              | name of mpirun executable     | mpirun
## AUTO_MPI_ARGUMENTS_TAG  | mpirun arguments              | -np 4
## EXTRA_MPI_ARGUMENTS_TAG | extra mpirun arguments        | -x FAST=1

III. Step-by-Step Instruction on Debugging

 

III-1. Start 'Run and debug a program'
