6 Debugging Applications
This chapter describes how to debug serial and parallel applications in the HP XC development
environment. In general, effective debugging of applications requires the applications to be
compiled with debug symbols, typically the -g switch. Some compilers allow -g with
optimization.
This chapter addresses the following topics:
•
“Debugging Serial Applications” (page 67)
•
“Debugging Parallel Applications” (page 67)
6.1 Debugging Serial Applications
You can debug a
on an HP XC system with the same method you would use
to debug a serial application on a conventional Linux operating system. For information about
debugging serial programs, see the standard Linux documentation.
The following serial debuggers are available for use in the HP XC environment for local
debugging:
•
The gdb utility is provided with the standard Linux distribution; it performs line-mode
debugging of a single process.
•
The idb utility is generally available with the Intel compiler suite.
•
The pgdbg utility is generally available with the PGI compilers.
For information about using these debuggers, see the standard Linux documentation and the
documentation that is available with the specific debugger that you are using.
6.2 Debugging Parallel Applications
The following parallel debuggers are recommended for use in the HP XC environment are
TotalView and DDT.
TotalView
TotalView is a full-featured GUI debugger for debugging parallel applications from Etnus, Inc.
It is specifically designed to meet the requirements of parallel applications running on many
cores. The use of TotalView in the HP XC environment is described in
. You can obtain additional information about TotalView from the TotalView
documentation and the TotalView Web site at:
Note:
TotalView is not included with the HP XC software and is not supported. If you have any
problems installing or using TotalView, contact Etnus, Inc.
DDT
DDT (Distributed Debugging Tool) is a parallel debugger from Streamline Computing. DDT is
a comprehensive graphical debugger designed for debugging parallel code. It gives users a
common interface for most compilers, languages and
distributions. For information about
using DDT, see the Streamline Computing documentation and the Streamline Computing Web
site:
