When XALT is enabled during builds: + - An XALT watermark is added to the ELF binary of the executable(s) - An XALT link record containing information about the build is created When XALT is enabled during application executions: + - An XALT start run record containing information about the execution is created; some link data is also included if the executable was built with XALT - If the execution exits normally, an XALT end run record containing information about the end of the process is created; if the process exits abnormally no end run record is created - For MPI jobs, XALT run records are produced only for rank 0
