Unstable power would be a definate challenge. Some types of work have checkpoints within a model. Others only checkpoint at the end of each model. The Project Team is working to add additional checkpoints in their next release in a couple of weeks. This should help preserve more of your work. There really is not anything on your side that you can change... unless of course you get a battery backup or something that keeps your machine running :) All you can do is set your General Preference to leave applications in memory while preempted. And avoid powering down your machine. Also, the main way to preserve work is to progress further in to working on a task. This will be true even when additional checkpointing is added. Since you have unstable power, I would suggest you not run many BOINC projects on a single machine. Having multiple projects means halting one to work on another, and each time you halt a project, you may have halted it at a point where work has not been preserved. Since you have 3 machines, I would suggest you divide your time between projects by setting up one project on each machine, rather then having several projects on each machine.

Ancient problem, NEVER fixed. Hey, here's a stupid suggestion. A manual checkpoint option. And here's the smart suggestion. Shutting down the computer normally should make sure there are checkpoints on all running work units. Just a perennial annoyance, but it's a major part of why I dropped the previous project I had been supporting after earning something over a million "Work done" units. Currently at 1.4 million on rosetta@home, but getting increasingly annoyed with work units that have no checkpoints for an hour or so at a time. For security and performance reasons I prefer not sleeping the computers, in case you were going to repeat that suggestion... |

There is no single fix to bring more frequent checkpointing. Each type of protein analysis has it's own structure and limitations for when checkpoints are taken. Taking a checkpoint is not like hitting save on an otherwise static spreadsheet. R@h tasks literally have thousands of things going on as they run. The processing hits points where things quiet down, especially at the end of a model. When such points are reached where a checkpoint can be taken and accurately restarted, checkpoints are taken. As specific approaches to analyze a protein are used more or future plans to use a given approach are made, additional checkpoints are added at some of the more difficult points in the processing of a model; or other times enhancements are made to reduce the runtime required per model (and checkpoints are always taken when a given model is completed). Are there specific patterns in the WU names where you are seeing the long times between checkpoints? Rosetta Moderator: Mod.Sense |
