Multiple task wait system for use in a data warehouse environment

A computer program product for multi-scalar data processing that manages multiple tasks in at least one job thread, comprising:

• a first set of instruction codes for grouping a set of related tasks in a group;
• data and control flows defined between the related tasks in the group;
• a second set of instruction codes for waiting for a successful implementation of at least one successor task, based on the data and control flows, prior to implementing a successor task in the group;
• and
• exit conditions defined for the group, so that the tasks to be included in a group completion decision are selectively controlled based on the exit conditions.
