Each symposium consists of three related sessions on the last day of PDC, and they provide much more detail about two key topics covered throughout PDC.  A Parallel Computing symposium extends the PDC discussion to how multi-core architectures will significantly increase available computing power and the opportunities that will create.  A Cloud Services Architectures symposium will step back from the various cloud services covered throughout PDC and discuss how best to connect local software to key cloud services.  Together, the two PDC symposia will help all developers, architects, and technical managers to better prepare for the challenges and opportunities that will come with increasingly more multi-core processing power coupled with powerful cloud-based services and platforms.
