Profiling with TAU

Important

There are a few important points to note before you start using TAU.

• The current version of PAPI (3.7.2) does not compile using Intel Compilers. Therefore, if you need TAU with PAPI, you will need to use GNU compilers.
• PAPI requires you to be running a version of Linux with hardware counters built into the kernel. This means a kernel version of 2.6.31 or later (Ubuntu 9.10 or Fedora 12). Earlier kernels can be patched, for more information visit the link below.
• PAPI also supports Windows XP/2000, although this has not been tested with OpenCMISS. Visit the link below for more information.
• http://icl.cs.utk.edu/viewcvs/viewcvs.cgi/PAPI/papi/INSTALL.txt?view=markup&revision=1.37.2.2
• This process was developed on the following setup, 64 bit Linux with kernel 2.6.32 using PAPI 3.7.2 and TAU 2.19. To avoid complications, try to proceed using a similar setup.

Look through the following pages for information on the setup, use and implementation of TAU in OpenCMISS.
