We have put the first WUs in the new acemd2 application.

Are these indicated by the application ...
ACEMD - GPU molecular dynamics 6.01 (cuda)?

Thanks - Steve

I get:

Wed 10 Feb 2010 05:56:59 PM CET GPUGRID Starting task 594-IBUCH_1000smd_pYEEI_100202-3-10-RND9182_0 using acemd2 version 602

Are you expecting the 60% increase with this application/task set combo?

Exactly as the beta.

OK, I think I follow you, I see the same when I find the relevant entry in the Messages tab in BOINC Manager. If you look at the Tasks tab, the Application column says it is ACEMD - GPU molecular dynamics 6.01 (cuda).

Can you please align whatever is necessary so at least the app name and version are the same?

I got two 6.01's

11/02/2010 01:09:08 GPUGRID Starting task 387-IBUCH_1000smd_pYEEI_100202-3-10-RND6076_1 using acemd2 version 601

Shows as 6.01 in BAM tasks

Shows as acemd2_6.01_windows_intelx86__cuda in Win Task Manager

Looks as though there are still 6.01's in the queue. I have one running, and one queued this end.

Is there any expected run time difference (as such) between 6.01 & 6.02?

Applications: 6.01 is Windows, 6.02 is Linux.

The "application" column in boinc manager is not relevant yet. What matters is the "messages" string. For now there are only a few WUs for the new app, more to come.

Old application,
Picked up these two tasks today,
5-GIANNI_BIND_751-81-100-RND2022
52-GIANNI_BIND_2-79-100-RND8818
Both use v6.71 (cuda23).
Although they say that they need 15% of one CPU each, they are actually only using about 1% between them. Tasks running on two GT240's on an i7-920 W7Pro X64, 7Threads enabled for CPU use, total CPU usage 88%. I freed up one thread to expedite the GPU tasks (the other 7 are crunching WCG tasks).
Are there many new application tasks compared to the older tasks?

It might be some consolation to others that my cards are getting the older, slower and wobblier tasks!

In project preferences you should be able to select the application.

OK, I know you mean:
Goto Your account, select GPUGrid Preferences, Select Edit GPUGrid Prefernces, and Deselect ACEMD - leaving ACEMD 2.

6 hrs and 25 minutes on my gtx 260 216 cores. i would say that it is faster.

I am also getting big performance improvements from my GTX260sp216:

Wouaaaahh !!
Awesome !!

I had a 6.70 and right after a 6.02 for the same kind of Wu on my GTX275
6.70 : GPU Time: 18,351.38 CPU Time: 9,129.17
6.02 : GPU Time: 12,894.11 CPU Time: 1,503.43

GPU Time: -30% CPU Time: -80%

Well done !!

Agreed, Well Done!
Some serious amount of improvement was achieved by refining the application.

Now seeing similar improvement on my GT240 cards:
1841813 1158304, 45,402.39 2,734.11 4,531.91 6,118.08 ACEMD - GPU molecular dynamics v6.01 (cuda)
1840137 1157154, 66,144.96 3,361.48 4,531.91 6,118.08 Full-atom molecular dynamics v6.71 (cuda23)

45,402.39s rather than 66,144.96s is a 45% GPU improvement.
CPU time also dropped by 23% on these CC1.2 cards.

Looks like a nice improvement between 30% and 40% on

# Device 0: "GeForce GTS 250"
# Clock rate: 1.84 GHz
# Total amount of global memory: 1073414144 bytes

My GT 240 512MB card on the same GIANNI_BIND WUs: an average of 36,200s for v6.01 and 56,344s for v6.71. as you can see quite a bit faster. Two differences: it seems the GDDR5 version is considerably faster in GPUGRID than the GDDR3 version.

The other difference is that my machine is running WinXP and yours Win7. Win7 is still showing a significant slowdown with the new app. While I don't have GIANNI_BIND WUs to compare as my Win7 GT 240 box hasn't gotten any yet, here's a comparison of IBUCH_1000smd_pYEEI WUs: the WinXP box runs an average of 30,350s/WU and the Win7 box is running an average of 34,400s/WU. This is even though the card in the Win box is running at 625MHz while the card in WinXP is at 600MHz. Both are GT 240 512MB GDDR5.

I guess the moral of this story for GPUGRID and the GT 240 is: for fastest performance run WinXP (either 32bit or 64bit is faster for any of the NVidia cards that I've checked), and buy the GDDR5 version rather than GDDR3.
