I have troubles with the deadline!

Look at Deadline Error

and see that the total of days is just 5 days (30 days suppose to be the standard) (Sent 30 december, deadline 3 januari)

Although the majority of WU have deadlines of 23 to 24 days, it can vary from a low of 4 days to a high of 55 days depending on the Angle Range (AR) of the WU. This provides enough time for even a very slow computer to complete the expected work needed to analyze a specific WU without delaying to much the reissue of the WU should it be necessary to achieve a quorum of three good results.

The following was copied from Seti Enhanced FAQ at BOINC miniFAQ.
What is an "AR" or What is an Angle Range?

The "AR" is the "Angle Range" of the work unit. This basically describes the angle at which the Arecibo Radio Telescope was "tracked across" the sky to record the information that is contained in that particular work unit.
If the AR or Angle Range of the unit were 0 this would mean that the telescope (The SETI receiver portion of the telescope) was actually tracking that particular point in the sky. Larger AR's are due to the SETI receiver being swept across the sky as the work unit is recorded. AR's of approximately 0.4 result from the telescope not moving at all but just turning with the earth. Larger AR's are a result of the telescope being swept from one point of the sky to another during a recording.

I would like, at least, to get credit for work done within 4 weeks even if the deadline was 5 days. I have a laptop that gets turned on only on weekends, or is not often connected to the internet. If it does not have the full four weeks to process a WU, then I do not get credit. Actually, I have uninstalled Boinc on that machine since I have gone nine months without credit.

Thank you for your description of Angle Range. I assume that an AR of 0 takes less time to process. Is there a place that goes into more detail about the relationship between AR and processing time?


Focus on creating an intense desire to make yourself a better person.

A computer that is only used intermittently on weekends does not meet the minimum requirement to crunch for Seti. There are some other projects with very short crunch times that may suit it better but they would also require that you drain your cache and that the work be reported immediately before putting the laptop away to receive credits and not waste CPU cycles. You will have to research which one might meet your specific needs and interest.

For a fuller explanation of AR (angle range) do a search in the Boinc Wiki. Link in my signature.
