After 46 hours of computing:

1st Task: 45h50m14s/4.772% = 960h32h43s total computing time, which is 43.8% of granted time.

2nd Task: 45h12m42s/4.645% = 973h20m26s total comp. time making 44.4% of granted time.

Somehow, it´s getting better. Or my math is sloppy...?

Thank you all for the interest and useful information.
I didn't know about the option in the CPDN.
Astropulse on the first machine really did come to sense (estimated cca 80 hours instead of originally predicted 400 something).

My machine No.2:
ASUS Notebook X58L Series
MS Vista Home Premium 32-bit SP2
Intel Pentium Dual CPU T3200 @ 2.00GHz, 2,0GB RAM,
GPU: Mobile Intel(R) GMA X3100 (448 MB)

All calculations for (90% CPU time, 90% swap space, 90% memory, 100% CPU frequency)

Workunits (4 228 962 GFLOPs each)
1) hadcm3n_o7fv_1940_40_007444247_2
2) hadcm3n_o6dw_1940_40_007444039_0

Granted times (thanks to http://www.timeanddate.com/date/duration.html)
1) From 9 Sept 2011 8:27:00 Till 9 Dec 2011 14:56:43 ie. 7 885 783 seconds
2) From 9 Sept 2011 9:27:42 Till 9 Dec 2011 15:57:25 ie. 7 885 783 seconds

After some 30hours of crunching it looks like this:

Workunit 1) 2.891% in 29:54:40
ie. 122259.29142 GFLOPs in 107680sec giving CompPower of: 1.114 GFLOPs/sec

Workunit 2) 2.77% in 29:18:27
ie. 117522.85398 GFLOPs in 105504sec giving CompPower of: 1.135 GFLOPs/sec

Necessary computing time in this configuration:
1) 4 228 962 GFLOPs/1.114 GFLOPs/sec = 3796195,7 seconds (which is 48% of Granted time ie. cca 11.5 hours of computing each day to meet the deadline)
2) 4 228 962 GFLOPs/1.135 GFLOPs/sec = 3725957,7 seconds (which is 47% of Granted time ie. cca 11h and 17min of computing each day to meet the deadline)

OK, so I've learned my lesson. Night shifts for present tasks and change the model preferences for the next.

Thank you again for help.

Thanks for encouraging answer.
I will post the real computing times and a percentage of "real computing time"/"assigned time", when workunits are done.

Thank you for sympathy. I didn't mean to whimper. I'm just a little saddened, that the original idea of spare time crunching was effectively put away.

By climateprediction.net I got task demanding 13 hours of computing a day to make it on time.
By SETI@home I just got some new type of SETI "Astropulse" task demanding almost 7 hours of computing a day to catch the deadline.
All that with nonstop 90% CPU usage, 90% RAM usage at 100% CPU frequency.
I know, that if I do not like it I need not to do it, because there is probably superfluous computing capacity in these projects, but wasn't this once supposed to be fun?
