I agree abut your remark as distributed architectures. This is my day-job, and I like it a lot :-)
I did not make the problem clear enough I think: the workload I am talking about are mostly idle jobs, so the CPU and memory load for each job is *very* low. Yes, I can beat the problem with more cores or nodes, but that seems very much like a waste, as those would be all idling most of the time.
Assume you plan for 1000 threads per core, and use quad code nodes - that would require 25 nodes which all idle all day long :-(
Some more detail, if that helps: the idle processes/threads are basically watchers, which represent a CPU/Memory heavy remote job they spawned, and whose state they are watching. Only when that state changes they become active, and kick of data movements or spawn new jobs.
We can't control the design of the remote job startup API very well (third party, synchronous API only), thus our technical options for obtaining state information about those jobs are limited, and boil down to
So, I can throw 25 nodes on that large for loop, and that is what we do basically - but what a waste...
The *real* workload are 100.000 CPU/Memory heavy remote jobs, which have sufficient resources to run concurrently. I am talking about the management side (our workflow engine).

I have a dual core pc, I write a application with two child process.
I know I can add sched_get_cpu to know the process run on which core, but, it just when the sched_get_cpu is called, it will tell me the result, my quesion is how to know the child proceess spend how many times on one core. (2 Replies)

Hello,
I have a 4 core machine.
Here is my initial script
cd /work/
python script.py input.txt output.txt 1 2 3
This script runs for 1.5hrs.
So I read across the web and figured out that you can use GNU parallel to submit multiple jobs using parallel. But I am not sure if I can run... (4 Replies)
