Latest commit

Libbfd generates references for these functions, but it doesn't
actually call them, at least not how we call libbfd.

This allows toolkit to build and link with binutils +nls.  Previously,
the build would die with undefined references to libintl_dgettext().

Although hpctoolkit doesn't use NLS, this allows it to be part of a
larger spack build that uses binutils +nls.

HPCToolkit is an integrated suite of tools for measurement and analysis of program performance on computers ranging from multicore desktop systems to the nation's largest supercomputers. HPCToolkit provides accurate measurements of a program's work, resource consumption, and inefficiency, correlates these metrics with the program's source code, works with multilingual, fully optimized binaries, has very low measurement overhead, and scales to large parallel systems. HPCToolkit's measurements provide support for analyzing a program execution cost, inefficiency, and scaling characteristics both within and across nodes of a parallel system.

HPCToolkit is released under the 3-clause BSD license. See the file README.License for details.

Build Instructions

Build instructions are available at:

HPCToolkit can be installed either by the one-button spack install hpctoolkit method, or by building the prerequisites with spack and then using the classic autotools configure && make && make install method.


Documentation is available at the HPCToolkit home page:

In particular, there is a PDF User's Manual at:

Bug Reports and Questions

The best way to contact us for bug reports or questions is via the mailing list hpctoolkit-forum =at= The mailman list is technically members-only, but you don't really need to be a member. Just send mail to this address and then we can white-list you.

If reporting a problem, be sure to include sufficient information about your system, what you tried, what went wrong, etc, to allow us follow your steps.

  • type of system, architecture, linux distribution and version, compiler version, glibc version.

  • hpctoolkit version.

  • if a build failure, then the config.log file from the build directory and the output from make.

  • if a run failure, then what command you ran and how it failed.

You can’t perform that action at this time.
