- Compile the relevant application modules with support for debug information by using the-g(Linux* OS) and/Zior/Z7(Windows* OS) compiler flags. For example:$ mpiicc -g -c ctest.c
- Enable Program Counter (PC) tracing by setting the environment variableVT_PCTRACEto5for example:$ export VT_PCTRACE=5Alternatively, set theVT_CONFIGvariable to the configuration file specifying the following, for example:# trace 4 call levels whenever MPI is used ACTIVITY MPI 4 # trace one call level in all functions not specified # explicitly; can also be for example, PCTRACE 5 PCTRACE ON$ export VT_CONFIG=<config_file>
Product and Performance Information
Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
