Vidocq, the FAAH Work Units are split in segments/sections/chunks/parts of a fixed percentage length. UD has to finish each as they are uninterruptable computations, so large that saving them every few minutes would probably stop your computer from doing anything else. Sofar the segments identified can be of different lengths thus you have to be observant when you stop UD in the middle of a FAAH calculation

Type 1. Saves AFTER 16.66 , 33.33 , 50.00 , 66.66, 83.33, 100.00
Type 2. Saves AFTER 33.33 , 66.66, 100.00
Type 3. Saves AFTER 50.00 , 100.00
Type 4. Saves ONLY when 100% complete!

The moment the first red line appears in the C:Best Docking Energy, indicates/confirms also what FAAH type you have in the present batches i.e. if the read line appears just at 16.66% and the green line retreating to the beginning of the graph, you got a type 1.

Going from 90 to 66.66 suggests you had a Type 2 (my private numbering). I dont know of smaller segments at present on FAAH, the single segment identified by Retsof.

(HPF2 and HDC have simular segmentation, albeit different percentages)

It's really a case of watch and learn.....the subject been covered in this forum many a time and conveyed in different ways.....this, my 2 cent version.......

PS, you have to look at the 'i' graphics screen progress bar percent as the |^| screen only shows the completed whole percentage i.e. 66.9 would still show as 66!

ciao

Vidocq, read my lips......what you saw was past tense...2 / 3 %, this is today's FAAH (FightAidsAtHome)!

PS you provide little information, not saying HPF1, HPF2 both very unlikely, which leaves FAAH which happens to have segments saves at 66.66%

bye bye

Vidocq, perhaps Sekerob wasn't clear.

This behaviour is normal. It should be fairly rare that you lose so much, but you will always lose a little bit when you stop the agent. After losing such a large chunk it is a good idea to leave the agent running for longer than usual to prevent it from happening again with the same work unit.

Remember, FightAIDS@Home checkpoints when the green line reaches the end. Shut the agent down when the green line has just started, and you will lose as little as possible.

Now having seen last 3 FAAHs, generating a red dotted line at 6.25% and the green returning to the beginning it's fairly certain a batch/batches is/are in circulation, that have 16 checkpoints (saw the "green line returning to beginning " behavior also at 33.3% and 50% where the green was returning and the red line was rescaling in the C: Best Docking Energy Graph. Thus here an update to the table of variations so far observed over time with FAAH.

You are thus save to close UD Agent after each of these percentage steps (can't guarantee though....24/7 gives lowest risk of Work Unit corruption or time loss). Below a sample of a Type 1 graph. The green line has just restarted and the red line indicating a segment end was reached at 16.66%.... if the percent is higher and no red line, the next possible would be Type 7, 25%, Type 2, 33.33 % etc etc.



Alternate, read the Hibernation Guide by DavidHobbs. The method writes a complete memory image to disk and lets you resume where you left off without a minute loss here when closing and restarting your PC.

Edit: Updated table 8.26.06 & 9.18.06

I think many take considerable effort here to offer solutions. Just switching off FAAH, whilst being presented the Hibernation solution, is the easy way out. Switching off your computer ALWAYS looses some crunch time as the work unit ALWAYS will return to last segment/chunk beginning it last started before shutting down. With Hibernation u have the chance of not loosing a second.....just resume exactly where u left off!

No guarentees......but i challenge u to try it
