- What limits are there to transfer_input_files? I would sometimes get Failed to transfer files when the number of files was around 10,000
- ANSWER: There is a memory limit because of ClassAds but in general there isn't a defined limit.
- Is there a way to generate the dag.dot file without having to submit the job?
- The -no_submit option doesn't create the .dot file
- Is adding NOOP to all the JOB commands the right thing to do? The DAG still gets submitted but then quickly ends.
- ANSWER: You need to submit the DAG. NOOP is the current solution
- Is there a way to start a dag at a given point? E.g. if there are 5 steps in the dag, can you start the job at step 3?
- Is the answer again to add NOOP to the JOB commands you don't want to run?
- ANSWER: Splices may work here but NOOP is certainly a tool to use.
- I see at CHTC jobs now require a request_disk setting. How does one launch interactive jobs?
- ANSWER: This is a bug.
- For our initial tests, we want to flock jobs to CHTC that transfer about 60GB input and output. Eventually we will reduce this significantly but for now what can we do?
- Globus or rsync to move data? If Globus, how to do so in an automated way (E.g. no password)?
- ANSWER: Using the Transfer Mechanism from our submit server to CHTC's execution host is ok with CHTC because it doesn't interfere with their submit host. Outbound from their execute hosts is also allowed (scp, rsync, etc).
- Use +Longjob Longjobs = true attribute for 24+ hour jobs. This is a CHTC-specific knob.
