System and method for efficiently performing memory intensive computations including a bidirectional synchronization mechanism for maintaining consistency of data

A method in a computer system for efficiently performing memory intensive computations, the method comprising the steps of:

• performing a first update operation on a second data set stored in system memory to reflect changes that have occurred in a first data set stored in a database;
• performing at least one computation using the second data set to determine a first solution;
• and
• re-performing the at least one computation using the updated second data set to determine a second solution when the first update operation occurs during performance of the at least one computation, in order to include the changes to the first data set in the production of the second solution.

A computer program product embedded in a computer readable medium for efficiently performing memory intensive computations, comprising:

• program code for performing a first update operation on a second data set stored in system memory to reflect changes that have occurred in a first data set stored in a database;
• program code for performing at least one computation using the second data set to determine a first solution;
• and
• program code for re-performing the at least one computation using the updated second data set to determine a second solution when the first update operation occurs during performance of the at least one computation, in order to include the changes to the first data set in the production of the second solution.
