1) Message boards : Number crunching : AMD ATI Radeon HD 2300/2400/3200/4200 (RV610) (336MB) - SETI/AP possible? (Message 1674296)
Posted 2 hours ago by Profile Dirk SadowskiProject donor
BTW, it's not my host.
How the member can detect the correct name of his GPU?
GPU-Z, at the top in the line 'Name'? Or there will be also just written HD 2300/2400/3200/4200?

AFAIK, ATI/AMD HD4*** could run SETIv7 and APv7, right? (from the LIv0.43a ATI page)

OS, Win7 x64, what would be the best driver for the SETI (and AP) project?

BTW, it's a laptop with AMD Athlon™ II Dual-Core M320 CPU. Not APU.
So the GPU is separately.

Thanks.

I looked in Lunatics Installer v0.43a ...
It looks like APv6 (CAL) calculation was possible on AMD/ATI HD2000 series.
APv7 is no longer possible?

Is there a way to calculate SETI or AP tasks on a (Windows OS): AMD ATI Radeon HD 2300/2400/3200/4200 (RV610) (336MB) ?

Thanks.

I do understand - that now, in this time, currently - his PCs don't have CPU tasks in their overviews.

I do understand - he saw (in BOINC) that a/the PC/s got CPU tasks in past.

After looking to the hosts/details/app_details there are no CPU apps.
But who knows, is this overview correct?

Server hiccup?

In past, a PC of me (AMD Phenom II X4 940 BE with 4x GTX260) which was offline, which stands in the corner and had no, no cable connected (power, LAN or something else), got suddenly tasks from the SETI server (their were shown in the host/tasks overview) ... - still mysterious.

As the team name suggests, our goal is to reach and remain at Rank #1 here and here. :-D


Your help is needed!

Join our team here at SETI@home and together we accomplish this goal! :-)

I understood your problem correct - you don't want that the SETI server send CPU tasks to your BOINC? (just a phrase, because BOINC decide which device get the project tasks)

If so, then you must un-/check like following:

Use CPU: O <- here uncheck the CPU
Use ATI GPU: O
Use NVIDIA GPU: X <- check NV GPU, so BOINC just ask for NVidia tasks
Use Intel GPU: O

... in your SETI@home preferences.

If this don't solve your problem, I have no other idea.
Because the CPU tasks don't fly around and search on their own idle devices. ;-)

the thing is I use ATi, nVidia & intel GPU's...so those 3 are selected! ;)

Hm, OK, really last idea of me. ;-)

Go to your PC overview, you see the column 'Location'.
The related PC which get CPU tasks from time to time, which 'Location' (--- (for default), home, work, school) he have?

Look to your SETI@home preferences:
Primary (default) preferences
Separate preferences for home
Separate preferences for school
Separate preferences for work

... if you unchecked the CPU (at the location the PC is set).

I just discovered this today:
http://setiathome.berkeley.edu/workunit.php?wuid=1778912613

The computer of my wingman, equipped with a GTX750 also, did this task in less then 60% of the time it took my machine to crunch it.

I wonder why there's so much difference and why my machine is so slow. OK, the GPU from my wingman has more memory and slightly more clockspeed, on the other hand I am running lunatics apps and he doesn't. So why is his machine so much faster?

Ofc, besides the GPU his computer is much better (and newer). Is it possible that my rather old CPU and slow memory is the problem? Or the mainboard? There has to be a bottleneck somewhere that slows the GPU down. Any other thoughts?

And Garrett, when you maybe read this here: Do you run 2 instances on your card also?

Send a PM to Garrett and you know it ...
Until now this service is for free. ;-)

How much SETI tasks you let run simultaneously on your GTX750? If just one ...
Because of the times, I guess he let run 2 tasks simultaneously (if he use the app_config.xml file).

Or you let run also 1 SETI and 1 AP task simultaneously on your VGA card?
Then the AP tasks could slow down the SETI task calculation - I guess ...

I saw.

And your proposed solution?

Suggest they get a more reliable internet connection?

I certainly Not going to PM that to them.

Maybe the DSL router need a cold reboot?

I saw.

And your proposed solution?

No solution needed. BOINC is fault-tolerant, and will make resends as needed. At least one of the workunits has already validated.

Good catch.

1 task with a ratio of survival 3/2.

3 error results:
http://setiathome.berkeley.edu/show_host_detail.php?hostid=7560694 (PC with a weak web connection?)
http://setiathome.berkeley.edu/show_host_detail.php?hostid=2360076 (a Win98SE PC which make just errors)
http://setiathome.berkeley.edu/show_host_detail.php?hostid=6621400 (PC with a NV Quadro NVS 295 card which trash all AP tasks which he can catch)

2 successfully results.

To sum, 'a regular SETI day'.

Does anyone actually look at peoples hosts before they post?

Claggy


No, I just write, because I like to write.

I did.

I thought he meant in past.

I have no idea how long WCG tasks lasts.
I have no idea how the project shares are.

Maybe BOINC ask just here and there to CPU tasks at SETI (the 60 secs loop in BOINC?)?

No. ;-)

I guess I took the wrong 'disk' instead of 'platter'?

It's just one real HDD, inside of this device are 3 platter (in my case).

I just wanted to make from one real HDD (C) three theoretically HDDs (C, D, E (partitions)).

1TB WD VelociRaptor 64MB 3.5" SATA 6Gb/s - WD1000DHTZ (2.5" HDD in a 3.5" 'heatsink')


Like I wrote I'll go with the above mentioned HDD.

It's 1TB (1000GB) HDD, but later it will be just 932GB für usage.
AFAIK, this drive have 3 disks inside.

How to speed up this HDD?

I make three partitions (C, D, E) each disk one virtually HDD (each with 310.6666666666667GB).
Windows to C.
BOINC files folder to D.
BOINC data folder to E.

(Each disk inside the HDD have his own read/write heads.)

This would speed up something? (e.g. shorten access times)

Thanks.

Posted 2 days ago by Profile Dirk SadowskiProject donor
'Resend lost tasks' is a 'server thing' - you can't decide if on or off (or you don't have the control about it, to use it if you want/if it's needed).
AFAIK, this feature is currently switched off by the admins.

If the tasks are abandoned now, they will be send to other PCs.

I didn't meant you. ;-)

It was for all, because of the much earlier messages here in this thread.
I just wanted to also give my two cents.

So it't better to use ATI/AMD VGA cards for OpenCL apps. ;-)


@ all
I understand some messages here in this thead like, to find the 'guilty' person who made this BUG (NV VGA card, OpenCL app, use one whole CPU thread for support), correct?
OK, just an opinion/contemplation of a regular SETI user.

For Windows there are 3 OpenCL apps available, for ATI/AMD & NVidia VGA cards and Intel's iGPU.

AFAIK, the basics of this 3 OpenCL apps are the same, just 'small' adjustments for the 3 different devices.

AFAIK, ATI/AMD VGA cards and the Intel's iGPU don't use one whole CPU thread for support if OpenCL apps running (not needed to use -use_sleep).
On NVidia VGA cards, OpenCL app, one whole CPU thread for support (-use_sleep needed for to free the CPU thread).

BTW, the v263.06 NVidia driver with WinXP x86, I saw there no one whole CPU thread support if OpenCL on my GTX285.


So who is the 'guilty' person? I guess (IMHO) it's NVidia. They sabotage with their (newer) drivers the correct (and fast) execution of OpenCL apps for to say 'hey look, CUDA is the 'better' way'.

After - http://milkyway.cs.rpi.edu/milkyway/apps.php - I saw MWv1.00 is for CPU. ;-)

If I read your message correct, one AP v7.10 OpenCL app use -use_sleep and the other AP v7.10 OpenCL app don't use -use_sleep? Correct?
But currently I can't imagine how to set this ... ;-)

Posted 3 days ago by Profile Dirk SadowskiProject donor
Since nobody cares to make an answer, ok, what i state is correct, so how to talk against... ;)

Here you can see the CPU usage with driver 337.88:


With newer driver the usage rise up to 1 core per AP-GPU-unit, no matter what, and all other CPU WUs starving to death...


In this time your VGA cards crunch a Milkyway and two APv7 tasks.
You have two, a GT640 and a GT430 in this PC.

Which apps/tasks running on which card?

AFAIK, to the time I crunched Milkyway on my GTX285 with WinXP x86 it was the same (1 Milkyway task on GPU) the MW app used one whole thread (50% of Duo-CPU). Also with the v263.06 NV driver which have not the OpenCL BUG.

BTW. I can't see the end of the MW app (the column is to small), it's a CPU or GPU app?

Posted 3 days ago by Profile Dirk SadowskiProject donor
AFAIK, with the old NV drivers you could choose (advanced installation) if NVidia's PhysX should be installed or not.
In this time I installed just the VGA card driver, because I don't play on the PC, just CUDA and OpenCL.

Also I know, from the forum that if you crunch just with CUDA or OpenCL apps on your NVidia VGA card, PhysX is not needed.
If you play games also, of course it should be installed. ;-)


Tasks (& results) overview of one of your PCs: http://setiathome.berkeley.edu/results.php?hostid=7349323

The above task 06dc12ab.491.10297.438086664201.12.154_0 which is currently on your PC: http://setiathome.berkeley.edu/result.php?resultid=4124841985 - this change, if your PC calculated this task, it's a result.

If both PCs sent results which match, after ~24 hours the task (the results of two PCs): http://setiathome.berkeley.edu/workunit.php?wuid=1778284730
... disappears.
