With rapid dissemination of cloud computing, data centers are quickly turning into platforms that host highly heterogeneous collections of services. Traditional approach to security and performance management finds it difficult to cope in such environments. Specifically, it is becoming increasingly difficult to capture and process all the necessary information at data centers in real time, where packet capture at data center gateways can serve as a practical example. This paper proposes a generic design for capturing and processing information on multicore architectures. The two main parts of the proposal are (1) the optimization formulation for distributing tasks across cores and (2) practical design and implementation of a shared memory which can be used for communication between processes in a non-traditional way that does not require memory locking or message passing.
