(GLOBAL:*:DATA_TRANSMISSION_CORRUPTED)
After checking that the data type signatures in a point-to-point message transfer or collective data gather/scatter operation at sender and receiver match, Intel ®Trace Collector also verifies that the data was transferred correctly by comparing additional checksums that are calculated inside the sending and receiving process. This adds another end-to-end data integrity check which will fail if any of the components involved in the data transmission malfunctioned (MPI layer, device drivers, hardware).
In cases where this
GLOBAL:*:DATA_TRANSMISSION_CORRUPTED
 error is obviously the result of some other error, it is not reported separately. This currently works for truncated message receives and data type mismatches.

Product and Performance Information

1

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.
