Data Modified during Transmission
(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.
