The results of filling jobs to workers. The colored bars mean that workers performed assigned jobs. The white space means workers waited for assigned jobs. Workers that performed jobs from a coinciding task were given the same color. Colors were used cyclically. The number of workers was 5,000. Figure (a) is an enlarged image of Figure (b) framed by a light green box. (1) Workers performed fastq_splitter tasks. The number of these tasks were 28, so that most of workers were sleepingt. (2) The first three tasks of bwa_align were assigned to workers and started at almost the same time. There were still sleeping workers because the other fastq_splitter had been calculating. (3) These workers first performed jobs belonging to a red-colored task and accomplished them. Then, they immediately started the next jobs belonging to a yellow-colored task. The complicated results shown in Figure (a) indicate that each worker worked independently and continuously despite the computational costs of each task being quite different
