Data flow graph computation using exceptions

A computer program product embodied in a non-transitory computer readable medium for data manipulation, the computer program product comprising code which causes one or more processors to perform operations of:

• configuring a plurality of processing elements to implement a data flow graph;
• loading the plurality of processing elements with a plurality of process agents;
• executing valid data by a first process agent on a first processing element from the plurality of processing elements, wherein the first process agent corresponds to a starting node of the data flow graph;
• detecting, by a second processing element from the plurality of processing elements, that an error exception has occurred, wherein a second process agent is running on the second processing element;
• raising, by the second process agent, an interrupt request, wherein the interrupt request is based on the detecting, by the second processing element from the plurality of processing elements, that the error exception has occurred;
• and
• in response to the interrupt request, withholding a done signal, by the second process agent, to a third process agent, wherein the third process agent is running on a third processing element from the plurality of processing elements.

A computer system for data manipulation comprising:

• a memory which stores instructions;
• one or more processors coupled to the memory wherein the one or more processors, when executing the instructions which are stored, are configured to:
• configure a plurality of processing elements to implement a data flow graph;
• load the plurality of processing elements with a plurality of process agents;
• execute valid data by a first process agent on a first processing element from the plurality of processing elements, wherein the first process agent corresponds to a starting node of the data flow graph;
• detect, by a second processing element from the plurality of processing elements, that an error exception has occurred, wherein a second process agent is running on the second processing element;
• raise, by the second process agent, an interrupt request, wherein the interrupt request is based on detection, by the second processing element from the plurality of processing elements, that the error exception has occurred;
• and
• in response to the interrupt request, withhold a done signal, by the second process agent, to a third process agent, wherein the third process agent is running on a third processing element from the plurality of processing elements.
