how to run sleep task benchmarks on EC2

[Iman Sadooghi]

I m trying to run a large scale experiment on EC2 running millions of sleep tasks. I was able to deploy Sparrow and run sample commands like this:

./ec2-exp.sh command all-open 'sleep 1' -k key -i /home/user/key.pem 

this would run the sleep job once in each node for me. I would like to run for example 1024000 tasks on many nodes and measure the performance of sparrow. I dont know how to set up the system to run a complete benchmark like this.
