I often have the feeling that units mysteriously appear and disappear. It would be nice if there were a 16 bit integer available in the Cray compiler, but apparently that is not possible. I also encountered some problems to run jobs on J90 for saving checkpoint files. I think they may be understaffed, but I've had really slow response times to my requests. I'm not saying that they are not qualified for the job, but just that they take too long to attend requests.
Service is very dependent on who it is that answers the phone.
My initial encounter with consulting services was unfortunate. I was having difficulty managing a complicated application, and was called by a consulting services member who confronted me with a challenging and somewhat threatening tone. Following this incident, however, I received helpful and respectful advice from another consultant, and was able to improve the application. We have some difficulties at the beginning of FY2000 which non-PIs of continuing accounts getting their setcub ceiling reset to zero. Then they were prohibited from running batch.
