[edit] Defect Type Description

This defect type is intended to cover defects associated with a race condition. It is currently classified as a sub-type of the Synchronization type. A common example of this type in HPC applications is a conflict between network communication and memory access: a race condition can occur if the memory area is rewritten while it is still used for communication.
