 There are many practical reasons for using the <tt>HEPMDB</tt> computing mainframe. Convenience may be the most obvious one; no installation is needed and it is simple to compare results between various matrix element generators. Also, <tt>HEPMDB</tt> has some integrated tools for plotting and analysing that are really quick to use.
-Another reason is simply the efficiency; with 12 cores, <tt>HEPMDB</tt> is much faster than most local installations.

 HEPMDB is a database that stores high energy physics models, and calculates theoretical cross sections for user defined processes in order to validate theory against experimental data. There are other projects similar to this, however HEPMDB is the <b>only</b> database that allows users to upload models, run processes <b>and</b> calculate cross sections on the site itself.

 === What is HEPMDB? ===
-<tt>The High Energy Physics Model DataBase (HEPMDB) was created to facilitate the connection between high energy physics theory and experiment, to store and validate theoretical models, and to develop a dictionary of the model signatures which identifies the fundamental theories responsible for signals expected at the LHC.</tt>
+HEPMDB is a database that stores high energy physics models, and calculates theoretical cross sections for user defined processes in order to validate theory against experimental data.

-In consequence, HEPMDB has a huge database of models and model signatures. In the future, HEPMDB will be able to compare BSM predictions with LHC data in order to discriminate between the different theories. The database is still in development. Currently, HEPMDB gathers various matrix element generators and models in order to compute cross-sections and cross-check the results.
