+  <abstract>
+    <p>
+      Programming systems that obey hard real-time constraints is difficult.
+      So is programming multiple CPUs that interact to solve a single
+      problem.
+    </p>
+
+    <p>
+      On rare occasions it is possible to mix two difficult problems to create
+      one easy problem and multi-CPU real-time is, on the face of it,
+      just such an occasion. Give each deadline its own CPU and it will
+      never be missed. This intuition is, unfortunately, incorrect, which does
+      not, however, prevent it being tried in many real-time systems.
+    </p>
+
+    <p>
+      For three decades, fourth year students have been exploring this problem
+      in CS452, using multiple tasks (virtual CPUs) running on a single CPU.
+      It is now time to consider whether modern developments in CPU
+      architecture make it possible to use multiple CPUs in CS452 given the
+      practical constraint of a twelve week semester.
+    </p>
+
+    <p>
+      This talk will describe the nature of computation typical of real-time
+      systems, architectural solutions currently employed in the course, and
+      possible architectures for multi-CPU systems.
