+Problem
+-------
 
+* a complex, large program that does stuff
+
+* stuff is mostly independent
+
+|pause|
+
+* ... but not quite
+
+* shared mutable state, however, not too much
+
+* we want to parallelize the problem
+
+Classic solutions
+-----------------
+
+* multithreading
+
+  * large shared state (tons of lock)
+
+  * no shared mutable state (copying, keeping in sync)
+
+* MPI - message passing, with limited shared state
 
 Demo
 ---------------------------
Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
