+\frame{\frametitle{What is High-Performane-Computing (HPC)?}
+ \begin{itemize}
+  \item Whenever speed is important
+  \item Tools for HPC: Cyberinfrastructure
+   \begin{itemize}
+    \item A workstation, desktop, laptop, smartphone
+    \item A supercomputer
+    \item Grid / Cloud
+   \end{itemize}
+ \end{itemize}
 }
 
+\frame{\frametitle{Why use Computers in Science?}
+ \begin{itemize}
+  \item Complex theories without (many) known analytical solutions; solutions
+        have to be found numerically
+  \item Impossible experiments; conditions cannot be met by lab experiment
+  \item Speed sometimes important, and usually computers can beat humans here
+ \end{itemize}
+}
+
+\frame{\frametitle{Examples}
+ \begin{itemize}
+  \item Smimulation of physical phenomena
+   \begin{itemize}
+    \item Climate modeling
+    \item Galaxy formation
+    \item Supernovae explosions
+    \item Fluid flow through porous media
+   \end{itemize}
+  \item Data mining
+   \begin{itemize}
+    \item Gene sequenzing
+    \item Tornado detection
+    \item Satellite surveillance
+   \end{itemize}
+  \item Visualization
+   \begin{itemize}
+    \item Reducing large data sets to understandable pictures/movies
+   \end{itemize}
+ \end{itemize}
+}
+
+\frame{\frametitle{Why should you care about HPC?}
+ \begin{itemize}
+  \item Your problem is big
+  \item Your problem is complex
+  \item You need an answer fast - usually within your PhD
+ \end{itemize}
+ However:
+ \begin{itemize}
+  \item Your computer is too small
+  \item Your computer is too slow
+  \item Your software is not efficient and/or not parallel
+ \end{itemize}
+}
+
+\frame{\frametitle{But you are not a computer scientist}
+ \begin{itemize}
+  \item Don't worry: most people in HPC are not
+  \item Skills you need:
+   \begin{itemize}
+    \item Common sense
+    \item Patience and creativity
+    \item Common sense
+    \item Some interest in technology
+    \item Common sense
+    \item Ability to deal with some ``jargon''
+    \item Common sense
+    \item Some basic programming (C/C++/Fortran)
+   \end{itemize}
+ \end{itemize}
+}
+
+\frame{\frametitle{But I am just a computer scientist}
+ \begin{itemize}
+  \item Don't worry: since most people in HPC are not, you have an advantage from the start
+  \item Skills you need:
+   \begin{itemize}
+    \item Common sense
+    \item Patience and creativity
+    \item Common sense
+    \item Some interest in scientific problems
+    \item Common sense
+    \item Ability to deal with some ``jargon''
+    \item Common sense
+    \item Programming in languages you might not like (C/C++/Fortran)
+   \end{itemize}
+ \end{itemize}
+}
+
+\frame{\frametitle{HPC is pragmatic}
+ \begin{itemize}
+  \item Performance is not always what matters: Time to solution is
+  \item Practical experience is most important
+  \item Leveraging existing solutions is preferred over inventing new ones
+  \item A good solution today is often worth more than a better solution tomorrow
+  \item However: a readable and maintainable solution is better than a complicated one
+ \end{itemize}
