PI Advanced Computing Engine (ACE) enables developers to build and test complex calculations within the Microsoft Visual Studio environment. PI ACE calculations can be scheduled with the same calculation logic being applied to multiple assets. We will present new features and enhancements in the upcoming version of PI ACE 2010, including 64-bit support and the ability to configure multiple PI ACE schedulers to simultaneously execute calculations. We will discuss details of performance improvements, caching and scalability. Topics will also include best practices and present code examples.
