queue launcher crashes with empty queue

FireWorks
1

Hi,

I’m trying to run a long workflow that dynamically creates new fireworks at every iteration. I’m running the workflow with a queue launcher in infinite mode. Usually after around 5 iterations (50-100 fireworks) the queue launcher crashes as follows:

2017-02-07 22:56:21,500 INFO Sleeping for 5 seconds…zzz…

2017-02-07 22:56:26,592 INFO Launching a rocket!

2017-02-07 22:56:26,616 INFO No jobs exist in the LaunchPad for submission to queue!

2017-02-07 22:56:26,616 ERROR ----|vvv|----

2017-02-07 22:56:26,616 ERROR Error with queue launcher rapid fire!

raise RuntimeError("Launch unsuccessful!")

RuntimeError: Launch unsuccessful!

2017-02-07 22:56:26,619 ERROR ----|^^^|----

It looks like the queue launcher thinks a firework is ready to launch, but then finds the queue is empty after calling launch_rocket_to_queue(). Any tips would be appreciated!

Thanks,
Jonathan

Just to get a bit more info, does the issue persist when you restart the queue launcher? Also, are you using fill mode?

Best,

Yes, the queue launcher crashes again after being restarted. I’m calling the queue launcher with fill_mode=false:

rapidfire(launchpad, FWorker(), qadapter, launch_dir=’.’, nlaunches=‘infinite’, njobs_queue=20,

njobs_block=500, sleep_time=None, reserve=False, strm_lvl=‘INFO’, timeout=None,

fill_mode=False)

Thanks,

Jonathan

Hi Jonathan

Two things:

  1. Can you paste the output of “lpad get_fws -s READY -d count” after the script crashes?

  2. Would you mind running the script again with strm_lvl=“DEBUG” and pasting the output again?

I haven’t seen or heard of this error before so it might take a little back and forth to figure out what’s happening.

Best,

Anubhav

Hi Anubhav,

Thanks a lot for the help. Here’s the info:

  1. Can you paste the output of “lpad get_fws -s READY -d count” after the script crashes?

I’ve tried this after two crashes now. The first was ‘1’ and the second ‘2’.

  1. Would you mind running the script again with strm_lvl=“DEBUG” and pasting the output again?

Here is the output, I’ve included a successful submission as well:

Hi Jonathan

Ok, unfortunately that doesn’t provide much additional information, although it does seem like there are READY jobs to run in the queue.

Can you try something else? Immediately after the crash, “cd” to the directory listed by the qlauncher and manually try to submit the script. e.g., for a PBS queue system this would involve typing “qsub FW_submit.script”. The directory is listed in the debug output you printed, e.g., atlas/u/jkuck/rbpf_fireworks/block_2017-02-08-17-35-21-007249/launcher_2017-02-08-18-54-39-731710 for the previous time you tried this.

Sometime, manually submitting the script can help clarify what errors (if any) are being thrown by the queuing system.

Best,

Anubhav

Hi Anubhav,

Correct me if I’m wrong, but I think the queue launcher is crashing before creating the launch directory. It looks like 'atlas/u/jkuck/rbpf_fireworks/block_2017-02-08-17-35-21-007249/launcher_2017-02-08-18-54-39-731710 ’ is the directory created by the successful submission.

The problem seems to be that somehow launchpad.run_exists(fworker) is evaluating to True in the while loop in rapidfire() in queue_launcher.py, but then false in launch_rocket_to_queue().

Best,
Jonathan

Hi Jonathan

Two things:

  1. Can you paste the output of “lpad get_fws -s READY -d count” after the script crashes?
  1. Would you mind running the script again with strm_lvl=“DEBUG” and pasting the output again?

I haven’t seen or heard of this error before so it might take a little back and forth to figure out what’s happening.

A bit more info, I’ve replicated the problem on a second cluster with the latest version of fireworks installed (1.4.0). The second cluster uses slurm instead of pbs. The only observable difference is the line where the error occurs, because I’m running the new version of fireworks:

Hi Anubhav,

Correct me if I’m wrong, but I think the queue launcher is crashing before creating the launch directory. It looks like 'atlas/u/jkuck/rbpf_fireworks/block_2017-02-08-17-35-21-007249/launcher_2017-02-08-18-54-39-731710 ’ is the directory created by the successful submission.

The problem seems to be that somehow launchpad.run_exists(fworker) is evaluating to True in the while loop in rapidfire() in queue_launcher.py, but then false in launch_rocket_to_queue().

Ok, unfortunately that doesn’t provide much additional information, although it does seem like there are READY jobs to run in the queue.

Can you try something else? Immediately after the crash, “cd” to the directory listed by the qlauncher and manually try to submit the script. e.g., for a PBS queue system this would involve typing “qsub FW_submit.script”. The directory is listed in the debug output you printed, e.g., atlas/u/jkuck/rbpf_fireworks/block_2017-02-08-17-35-21-007249/launcher_2017-02-08-18-54-39-731710 for the previous time you tried this.

Sometime, manually submitting the script can help clarify what errors (if any) are being thrown by the queuing system.

Hi Jonathan,

I am looking over this issue again.

  • I agree with you that if “launchpad.run_exists()” evaluates to True inside the rapidfire() method but then the same method evaluates to False within the “launch_rocket_to_queue” a short while later, that you would see the error trace that you mentioned

  • This could certainly happen if, for example the following sequence of events occurred:

  • There is a READY job in the LaunchPad

  • that job gets submitted to the queue successfully, but it is still READY since we are not in reservation mode (that’s fine)

  • the rapidfire() code loops again, again sees the (same) READY job in the LaunchPad and goes ahead with calling the launch_rocket_to_queue() method to submit another queue job.

  • However, before the launch_rocket_to_queue() gets to the part where it checks again for the existence of a job (launchpad.run_exists()), the job already queued has started RUNNING. Thus, in between the two calls to launchpad.run_exists(), the FW went from READY to RUNNING leaving behind no jobs to run when the second call happened.

Do you think this is the sequence of steps that is occurring?

I see two ways forward

  1. If a ready job “disappears” by the time a queue is going to be submitted, simply consider the current iteration of rapidfire() to be finished

  2. Try to count jobs so that the same READY job doesn’t lead to 2+ queue submissions. This would potentially have some benefits in creating 1:1 mappings of jobs to queue submissions, although it would be very difficult to prevent two simultaneous qlaunch processes (e.g. on different machines/workers) from colliding.

Solution (1) is certainly easier to do and so I implemented it.

Please try FWS v1.4.1 (just released) and let me know if this fixes it.

Hi Anubhav,

Correct me if I’m wrong, but I think the queue launcher is crashing before creating the launch directory. It looks like 'atlas/u/jkuck/rbpf_fireworks/block_2017-02-08-17-35-21-007249/launcher_2017-02-08-18-54-39-731710 ’ is the directory created by the successful submission.

The problem seems to be that somehow launchpad.run_exists(fworker) is evaluating to True in the while loop in rapidfire() in queue_launcher.py, but then false in launch_rocket_to_queue().

Ok, unfortunately that doesn’t provide much additional information, although it does seem like there are READY jobs to run in the queue.

Can you try something else? Immediately after the crash, “cd” to the directory listed by the qlauncher and manually try to submit the script. e.g., for a PBS queue system this would involve typing “qsub FW_submit.script”. The directory is listed in the debug output you printed, e.g., atlas/u/jkuck/rbpf_fireworks/block_2017-02-08-17-35-21-007249/launcher_2017-02-08-18-54-39-731710 for the previous time you tried this.

Sometime, manually submitting the script can help clarify what errors (if any) are being thrown by the queuing system.

Hi,

I’m trying to run a long workflow that dynamically creates new fireworks at every iteration. I’m running the workflow with a queue launcher in infinite mode. Usually after around 5 iterations (50-100 fireworks) the queue launcher crashes as follows:

Hi Anubhav,

That sequence of events sounds like the problem to me. I’ve tried again with FWS v1.4.1 and tentatively the problem seems to be fixed, thanks a lot! I do have a couple of additional questions:

-I’m using an anaconda virtual environment on one of the clusters I have access to, but the latest version of fireworks I found is 1.3.9. Is there a way to get access to the latest version?

-When I run a workflow, a folder named something like “block_2017-02-13-22-14-42-132705” is created. Inside are a bunch of folders for each firework with names like “launcher_2017-02-13-22-15-50-842035”. When debugging I’d like to inspect the error file in the folder that corresponds to a particular firework with some a name I can view from the data stored in my database, such as the fw_id. Is there a way to rename the “launcher…” folders with fw_id’s?

Thanks,

Jonathan

Hi Jonathan,

I am looking over this issue again.

  • I agree with you that if “launchpad.run_exists()” evaluates to True inside the rapidfire() method but then the same method evaluates to False within the “launch_rocket_to_queue” a short while later, that you would see the error trace that you mentioned
  • This could certainly happen if, for example the following sequence of events occurred:
  • There is a READY job in the LaunchPad
  • that job gets submitted to the queue successfully, but it is still READY since we are not in reservation mode (that’s fine)
  • the rapidfire() code loops again, again sees the (same) READY job in the LaunchPad and goes ahead with calling the launch_rocket_to_queue() method to submit another queue job.
  • However, before the launch_rocket_to_queue() gets to the part where it checks again for the existence of a job (launchpad.run_exists()), the job already queued has started RUNNING. Thus, in between the two calls to launchpad.run_exists(), the FW went from READY to RUNNING leaving behind no jobs to run when the second call happened.

Do you think this is the sequence of steps that is occurring?

I see two ways forward

  1. If a ready job “disappears” by the time a queue is going to be submitted, simply consider the current iteration of rapidfire() to be finished
  1. Try to count jobs so that the same READY job doesn’t lead to 2+ queue submissions. This would potentially have some benefits in creating 1:1 mappings of jobs to queue submissions, although it would be very difficult to prevent two simultaneous qlaunch processes (e.g. on different machines/workers) from colliding.

Solution (1) is certainly easier to do and so I implemented it.

Please try FWS v1.4.1 (just released) and let me know if this fixes it.

For the other two items, can you submit separate tickets? This will help keep things organized for people looking for answers to common questions.
