请帮我建立算法:避免cloudsim中的瓶颈任务
Input :workflow w
Output :Queues of tasks based on depth and length
Assign thresholds dt for depth of tasks and lt for length of tasks
for each task t in the task list do
depth = number of levels dependent on t
length = execution time of t
if depth>= dt then
move t to depth queue
end
if length>= lt then
move t to length queue
end
end
Return queues
