That is, if I pause a long run task a few times a day, will this make it more likely I'll get a computation error or invalid result? | |

That is, if I pause a long run task a few times a day, will this make it more likely I'll get a computation error or invalid result? Hello: It is possible that. The way to reduce this is what I do when I have to stop work is as follows. A) Options Memory Disk Usage and uncheck the option that the application remains in memory when suspended. B) First time suspended and a suspended task BoingManager Exit. By doing this the moment I have not missed any work because of this. Greetings. | |

A) Options Memory Disk Usage and uncheck the option that the application remains in memory when suspended. I just use Snooze or Snooze GPU, and these work fine with LAIM. LAIM does not quite work the same for GPU's as it does for CPU tasks; for CPU tasks, some can literally pickup where they left off, without any loss. For the GPU it tends to pickup at the last checkpoint (5min, or after a certain percentage of the task has been completed). Thus it should not cause errors in itself, but it could if you had a faulty RAM module or an error on your HDD. It is worth noting that the first checkpoint can be some way into the task, especially on slow GPU's, so I would suggest you look at the task properties and see just when it last checkpointed before closing, suspending or snoozing. PS. Some CPU projects also have LAIM as the recommended setting. | |
