-===== VSC-3: Performance Report (Allinea) =====
+===== 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 Allinea [[http://www.allinea.com/products/allinea-performance-reports]] and very simple to use, i.e. by simply inserting the call to ''perf-report'' prior to the usual execution of the program.

+This will result in the creation of two summary files in *.txt and *.html format providing an overview of the relative time spent in MPI, I/O, OpenMP etc. Note the 'Energy' section in recent releases !

-and finally the 'vasp.trc' and the 'vasp_events.edf' files need to

-This file (vasp.slog2) can be visualized with jumpshot.

-==== VAMPIR ====
-Currently a demo version of [[http://www.vampir.eu|VAMPIR]] is installed on VSC-1. It can visualize VAMPIRTRACE files, as well as other formats such as OTF
-Location on VSC-1: ''/opt/vampir''
-==== JUMPSHOT and PARAPROF ====
-Both are installed together with TAU.
