Jack007 (and anybody else)

Your VM should be set to grow freely in the OS. In TBird's example 8 concurrent A type would eat (looking on my own machine where 4 each use 730Mb) 5.9Gb. According file explorer mine has with 4 already grown to 4.7Gb.

The BOINC default disk use setting is actually 10Gb, though it hardly uses that, just for those special cases where large projects show up.

Sek:"The BOINC default disk use setting is actually 10Gb, though it hardly uses that, just for those special cases where large projects show up."
Does that setting include the system's swap/page file, or just the BOINC Data Directory?

Jack007's error message above indicates that the BOINC server at the WCG end does not know whether these big WUs will fit on our client machines, so it's up to us to work that out before we select DDDT2.
Perhaps the physical & virtual memory requirements for each type of DDDT2 WU be set out in a place that's easy to find, and perhaps an annotated link to this info should be put in the Device Manager project selection section.
Was a "participate in DDDT2 Type A" option considered?

For those wondering how to display VM size in Windows Task Manager, do View >> Select Columns.

Congratulations to the researchers & techs for their persistence and hard work in getting this project under way. Here's hoping we find some drug leads that become effective therapies for dengue, HCV, WNV, etc.

I got just 1 DDDT2 WU so far - a repair job. It seems happy @ 4h30m, 21.3%, mem 205MB, VM 670MB. All of the initial 1000 WUs seem to have gone out already.
[Edit]: Pending Validation after 20.2h. Extrapolation of 4h30/21.3% gives 21.1h, so its progress sped up. Initial estimate was 15.x hours.

New estimates this morning :

i7 920 @ 3GHz : 8 units simultaneously - 50 hours per unit
Q9450 @ 3GHz : 4 units simultaneously - 30 hours per unit
Q6600 @ 2,4GHz : 4 unites simultaneously - 40 hours per unit
T2050 @ 1.6 GHz : 2 simultaneous units - 100 hours per unit

My Pentium 4 doesn't support this project because is needed 750 MB ram or above.

Its interesting to find how this app adjust to memory allocation. On my 2GB, it uses around 200MB+ while on 6GB, its about 540MB+.

TBird, it seems that you have given us estimates based on BOINC's estimated time to completion.
If you want to show more realistic times you can safely extrapolate from the work already done. Progress seems to be very linear.

Personally I have one running in a Q6600 at 3.16 GHz and it should last between 39 and 40 hours (average 47 minutes between checkpoints - 2 %).

To all: About the (normal) 0.000 % phase at the beginning note that the first checkpoint is taken at 2.000 %, therefore be patient.

Cheers. Jean.
