In various threads, I have seen people mention something about a due date for work. What's that all about? Each WU is copied into exactly enough tasks to make certain the science gets done. However, some tasks are not returned, and there has to be a mechanism to ensure that the science gets done. So, each task has a deadline from the time it is assigned to a computer. If the task is not returned by the deadline, a replacement is generated and sent out. If the original is returned BEFORE the replacement, then the original will get credit if it validates. If it is returned AFTER the replacement, it is very unlikely to get credit (the only exception is when the validator is backlogged). These are soft deadlines in that the work may be accepted somewhat late, but the later the work is returned, the less likely that credit will be granted. For S@H tasks, (not AstroPulse) a 90MHZ Pentium could comfortably complete the tasks on time if it was left on almost all of the time. BOINC WIKI ID: 892507 ·

I see that the stuff it is working on right now is called Astropulse. It estimates that it will take over 200 hours to complete. I am letting it process the data for 6 hours a day, will that work out all right? ID: 892879 ·

I am letting it process the data for 6 hours a day, will that work out all right? I am not completely certain. I do know the AP estimates are a bit off, but I cannot remember whether it is high or low. If the estimate is right, it will take just over a month - which is, I believe, the deadline. However, it is unlikely that a computer is going to be able to finish the work in the 3 or 4 days that the estimate says the task will be late. BOINC WIKI ID: 892903 ·

If you divide the hours done by percentage done it will give you a more accurate run time. For your system I should think that will be under 100 hrs or less than 17 days at 6 hrs/day. The deadlines for Astropulse are 30 days. Boinc V7.2.42 Win7 i5 3.33G 4GB, GTX470 ID: 892927 ·
