Abstract: A server is configured for parallel processing. The server receives a plurality of rule sets from a client, retrieves a plurality of financial data sets from a remote data source based on the rule sets, formats the financial data sets in parallel for input into a data structure, and populates the data structure with the financial data sets in parallel without locking the data structure. Subsequently, in response to the server receiving a plurality of event messages from the remote data source, the server processes the event messages and the rule sets, and accordingly modifies the data structure in parallel without locking the data structure, with the event messages relating to the financial data sets.
