IntelĀ® Trace Collector 9.1 Update 2 User and Reference Guide
UNIFY-SYMBOLS [on|off]
VT_UNIFY_SYMBOLS
on
During post-processing Intel Trace Collector unifies the ids assigned to symbols on different processes. This step is redundant only if all processes define all symbols in exactly the same order with exactly the same names. As Intel Trace Collector cannot recognize this automatically, the unification can be disabled by the user to reduce the time required for trace file generation. Before using this option, make sure that your program really defines symbols consistently.
