Known Issues In TAU

TAU instrumentation

• Parsing of templated function in C++ takes place at the pre-linking phase so loop level instrumentation is not available for templated functions.

• Opari automatic instrumentation is not available in header files, however you can do manually instrumentation see tau_header_inst.sh.

• Memory tracking with mallinfo

  TAU uses the mallinfo call when available on a system. mallinfo is not 64-bit clean and is only accurate up to 4GB. The getrusage call is used on some other systems, but does not work at all for Linux systems.
