[edit] General

This is the unique identifier of a specific Result that was issued to a Participant and which records the progress of that Result by that Participant. As this identifier is normally only available as a link, it allows the navigation to the "Result" Page where detailed information about this specific Result is available. This identification number is the internal tracking number that is given to this specific Result so that it has a unique identity in the BOINC Database.

This identifier, the Result ID, is a number which is used by the database to track the Result (for database freaks, the Primary Key value). This is a positive integer that is used in the links connecting pages like the "Work Unit" Page to the "Result" Page. You will find that Result ID is labeled as "Task ID" when viewing results.

There is no information coded in this number, it is a simple large integer number that will grow until it reaches a value of about 2,147,483,647 if they are using signed long integer and 4,294,967,294 if they are using unsigned numbers. And if they are using a string data type, an effectively unlimited numeric range is possible (as long as they stick to strings shorter than 2,000 characters).

Ok, so what does all that mean? It means that this is the internal tracking number that is given to this specific result so that it has a unique identification number in the BOINC Database.

Contrast this with a Result Name. The Result Name is a derived name that includes the Work Unit Name with a suffix that is an underscore followed by a number that indicates the position of this specific Result in the series of Results generated from that specific Work Unit.

The Results are numbered from 0 to "N" with the maximum number of trials being set by the Project. For example, if the LHC@Home project only wants to try 5 times to process a Result to a successful conclusion we would see a Result series from "RESULT-NAME_0" to "RESULT-NAME_4"; with these Results being issued to five different Participants.
