On Linux* OS, Intel® Trace Collector does not support tracing of ROMIO*, a portable implementation of MPI-IO. Fully standard-compliant implementations of MPI-IO are untested, but might work.
This distinction is necessary because ROMIO normally uses its own request handles (
MPIO_Request
) for functions like
MPI_File_iread()
and expects the application to call
MPIO_Wait()
/
MPIO_Test()
. These two functions are supported if and only if Intel® Trace Collector is compiled with ROMIO support. In that case the wrapper functions for
MPI_File_iread()
are compiled for
MPIO_Requests
and might not work if the MPI and the application use the normal MPI-2
MPI_Request
.
Applications which avoid the non-blocking IO calls should work either way.

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.
