Many-task computing (MTC) aims to bridge the gap between two paradigms, high-throughput computing (HTC) and high-performance computing (HPC). MTC is reminiscent to HTC, but it differs in the emphasis of using many computing resources over short periods of time to accomplish many computational tasks, where the primary metrics are measured in seconds, not operations per month. MTC denotes high-performance computations comprising of multiple distinct activities, coupled via file system operations. Tasks may be small or large, uniprocessor or multiprocessor, compute-intensive or data-intensive,...
