Solution

ReportDescription
ElectricSimulator Use performance information from this build to predict approximate performance on a variety of cluster sizes. This requires --emake-annodetail=basic,waiting.
Files modified multiple times Show files that were modified (created, rewritten, or deleted) multiple times. This requires --emake-annodetail=basic,file.
Longest serial chain Find the sequence of serialized jobs with the longest end-to-end runtime in the build. This requires --emake-annodetail=basic,waiting,history.
Serialization analysis Find the explicit and implicit dependencies that cause serialization of any two jobs in the build. This requires --emake-annodetail=basic,waiting,history.

When troubleshooting problems related to missing targets or input files, it is very helpful to use --emake-annodetail=basic,file,lookup.

When file/network corruption is suspected during a build, using --emake-annodetail=md5 will generate md5 checksums of files that are read/written during the build.

Available --emake-annodetail options

basic Basic annotation
env Extended environment tracking
file Files read or written
history Serialization details
lookup All file names accessed
md5 MD5 checksums for reads/writes
registry Registry updates (Windows only)
waiting Complete dependency graph
