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 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

Bug Reports and Questions
The best way to contact us for bug reports or questions is via the mailing list hpctoolkit-forum =at= rice.edu. 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.
if a build failure, then the
config.logfile from the build directory and the output from
if a run failure, then what command you ran and how it failed.
