Next: Reducing the observations Up: PEPSYS general photometry Previous: Influencing the plan . ... If the telescope and instrumentation are unfamiliar to you, you may have trouble keeping to the schedule for the first night or two, so try to work with a previous observer on the equipment for a night or two of training before your observing run. If you fall behind, try to keep as many low-altitude observations of extinction stars as you can, and drop some circumzenithal ones if necessary. ...

... LWN.net FAQ . ... Read-copy-update (RCU) is a mutual exclusion technique which can operate without locking most of the time. It can yield significant performance benefits when the data to be protected is accessed via a pointer, is read frequently, changed rarely, and references to the structure are not held while a kernel thread sleeps. The core idea behind RCU is that, when the data requires updating, a pointer to a new structure containing the new data can be stored immediately. ...
