  • Would this not be considered rude in China or something?

    Part 2 in the "whine about Chinese academics" series (continued from DaShi's thread)

    The department here hosts a high-performance computing cluster containing a thousand processors or so. Everyone in the department, as well as a few researchers at collaborating institutions have basically unrestricted access to it (you can submit as many jobs on as many processors as you want, on a first-come first-served basis). I submitted a couple of small jobs running on like 5 processors at around noon (runtime ~1 day) and had another few (~10 processors' worth) ready to go when I got a mass email from a full professor who requested that all users hold off on submitting any more jobs for a few hours because he had some time-critical processes to run before he presented the results at a conference next week.

    So, being the reasonable fellow I am, I didn't submit my extra jobs (and even considered killing the ones I'd already sent). I can wait a few extra hours to get my results, but it does inconvenience me a bit. I check back a couple of hours later, and 3 different Chinese grad students (who don't work for the professor in question) have submitted enough jobs to choke up the entire cluster for a day or so.

    Holy ****, *******s. These kids are like 2nd or 3rd year grad students. Do they not realize how ****ing stupid it is to piss off a FULL PROFESSOR, or how ****ing low on the totem pole they are? The prof could easily request that these kids have their access to the cluster restricted.

    Did those kids get the e-mail?

      Yes. Everybody with access got it. Furthermore, all 3 submitted their jobs in short order after the email was sent (which is actually fairly unusual if you look at the usual pace of job submission) which tells me that they got the email, realized that it meant that there would be loads of free capacity on the cluster and shoved their jobs in.

      Oh, I just got an update email from the prof (again, mass emailed)

      He is PISSED.



      EDIT: the sysadmin for the cluster just shut down access to the submission queue. These kids are going to be in trouble...

          One of them inhabits an office a few doors down from mine. When I saw that he'd submitted 240 processors' worth of jobs I practically got up and let him have it. I'm sort of happy I didn't. This is going to be far worse for him than if I yelled at him enough for him to cancel his jobs...

              Sorry. This is as much drama as we're going to see out of this today, I think. There might be longer-term consequences. I will keep you updated.

                It's a job-based system? Is it a mainframe type system?

                There are priority levels on the system for a reason. Grad student's **** should be run as "nice"

                  Well, sometimes grad students jobs are important.

                  Our cluster at the lab has priorities depending on how many jobs you have run recently and what group are you are in.

                    Asher, this prof's jobs will likely be run by HIS grad students. Very few jobs are actually run by profs. 90+% are grad students. Also, I'm not sure how "nice" factors into it (if it's the Unix type of "nice" which assigns system resources). The cluster assigns the next job in line for which there are adequate resources. So if there's 300 processors free, one guy submits job A for 400 processors and then the next guy submits job B for 200 processors job B gets run immediately while job A goes on the queue. It's not usually an issue. Even the big jobs get run within a day or two.

                      Also, the cluster is fairly new, and funding comes from various sources. The committee has not yet set up formal access or priority protocols.

                        Seriously, though, they're going to need to set some protocols up soon. There's one guy who's been using 20-25% of capacity consistently (every time I check he's on this many processors) for the past 6 months.

                          WTF research could this ******* POSSIBLY be doing that has taken him 6 months on 300 processors?

                            What kind of processors?
