Apparatuses and methods for monitoring performance of parallel computing

A computer-implemented method comprising

• executing a plurality of processes to process data, wherein at least a portion of the processes are instances of parallelizable operators;
• displaying a graphical user interface to the user to enable the user to define a data flow graph representing, at least in part, a combination of the parallelizable operators and relationships among the parallelizable operators for processing the data;
• parallelizing the parallelizable operators to generate the instances of the parallelizable operators to process the data;
• and
• displaying graphical representations of the processes and the flow of the data through the processes as the data is processed by the processes, wherein a volume of the data process by each one of the instances of the one of at least one of the parallelizable operators is represented by a characteristic of a graphical representation of the flow of data associated with a corresponding one of the parallelizable operators.

Computer-readable medium storing a computer program comprising instructions for:

• parallelizing the parallelizable operators to generate the instances of the parallelizable operators to process the data;
• and
• displaying graphical representations of the processes and the flow of the data through the processes as the data is processed by the processes, wherein a volume of the data processed by each one of the instances of the one of at least one of the parallelizable operators is represented by a characteristic of the graphical representation of the flow of data associated with a corresponding one of the parallelizable operators.
