(GLOBAL:MSG)
For each application message, another extra message is sent which includes:
  • Data type signature hash code (for
    GLOBAL:MSG:DATATYPE:MISMATCH
    )
  • Checksum of the data (for
    GLOBAL:MSG:DATA_TRANSMISSION_CORRUPTED
    )
  • Stack backtrace for the place where the message was sent (for both of these errors and also for
    GLOBAL:MSG:PENDING
    )
Only disabling of all of these three errors avoids the overhead for the extra messages.
Buffered messages which are not received lead to a resource leak. They are detected each time a communicator is freed or (if a communicator does not get freed) when the application terminates.
The information provided includes a call stack of where the message was sent as well as the current call stack where the error is detected.

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.
