Error Reports
The GPA Error Report informs you of system errors and diagnoses them. Two types of
errors can occur:
•
Fatal errors that cause GPA to terminate.
•
Non-fatal errors, on which GPA bases its performance-enhancing recommendations.
GPA Requirements
GPA does not have to be run on the system being analyzed; the Measure data can be
moved to another Tandem system.
