-===== Performance Reports (ARM's formerly Allinea's) =====
+===== Performance Reports =====
 ==== Synopsis: ====
 ''perf-report'' is a lightweight profiling tool that provides basic information about where the computing time is actually spent in a given application. It is developed by ARM (formerly Allinea) [[https://developer.arm.com/tools-and-software/server-and-hpc/debug-and-profile/arm-forge]] and very easy to use, i.e. by simply prefixing the usual executable with a call to ''perf-report''.
+It is nowadays integral part of [[doku:forge|ARM's forge]].
