I think this is host dependend.

I belive is not, why? it´s happening on a totaly diferent OS & GPU, the same happening on a 2x690 who runs Win Server. The only thing they have in common is they use the same old I5 CPU.

After few test i made here remotely, i could confirm the problem is aparently related to the size of the -ffa_block, a 4096 block makes some WU ussing 150MB, larger sizes huge increase the memory usage, a 8192 makes the WU uses about 250MB and so on, the 1GB apears when you use a 16k block size.

For some reason who i cant understand until now, my hosts simply apears to ignore the -oclfft_plan 256 16 256 switch.


-oclFFT_plan is case sensitive.
Make sure FFT is upper case or just snip it from the read me.
-use_sleep -unroll 16 -oclFFT_plan 256 16 256 -ffa_fetch 8192 -ffa_fetch_block 4096-tune 1 64 4 1 -tune 2 64 4 1


You don't follow your own advice ;)
You often make the typo "ffa_fetch"/"ffa_fetch_block" instead of ffa_block/ffa_block_fetch
(I can't believe you type such a long line of switches, why not copy from your working ap_cmdline*.txt file? (and just change numbers if needed))

But if app ignores -oclfft_plan it will probably safely ignore also ffa_fetch/ffa_fetch_block

?

Well, it is rare occurrence of 'lucky' WU ;)

How do you find a particular task in the slots file. You have to go thru looking in each slot to fine it?

In BOINC Manager select the task
- click button [Properties] at left
- almost at bottom look for 'slots/X'

Or in BoincTasks for the same info - Right-Click the task -> Properties

Shouldn't the App Rename the New Bin files to the New Driver?

No, only new app version is generating new binaries.

Seems the 'new' apps (don't know since which version) makes new .bin for different driver:

My files:
AstroPulse_Kernels_r2690.cl_Turks.bin_V7_TWIN_FFA_CAL141646
AP_clFFTplan_Turks_32768_gr64_lr8_wg256_tw0_r2690.bin_CAL141646


But maybe if CAL version do not change (or not exist?) in new drivers this versioning do not happen - i.e. always CAL141848

Does SIV allow you to see how much memory is being used?

No

Just use Windows Task Manager or Process Explorer to see the current use

BoincTasks also show this - on Tasks and History tabs (you need to enable the columns)

Especially the History tab is useful as it shows the peak RAM usage during the task run (and you can check what was it for past tasks)

... You did restart the task right? Select All the GPU tasks, Suspend them, count to 10, then Resume them.

Easier to do the same:
'Snooze GPU'
Wait 5-10 seconds
un- 'Snooze GPU'

OK, if you later need it:

... in app_config. I forget how I used to write that.

Don't you have app_config.xml used on another computer?

You have CPU work on:

http://einstein.phys.uwm.edu/results.php?hostid=11238508&offset=0&show_names=1&state=1&appid=0

And yes (as already noted) - if you expect/want to do AstroPulse v7 on the GPU it will not happen with the combination 'NVIDIA GeForce GT 220 (1024MB) driver: 340.52'

See the new plan_class "cuda_opencl_cc1" / "opencl_nvidia_cc1"
- it is to avoid computers running 'old' NVIDIA GPUs with 'compute capability' 1.x + 'new' drivers 340.52+ to get tasks

That surprizes me, my older xp w/ 2 GB computer years ago ran these, it wasn't a fast computer.

How many "years ago"?
It was probably in 2007 or 2008 on "mobile AMD Athlon(tm) XP2200+":

There were IIRC at least 2 changes that involve "bigger search"
- the SETI@home Enhanced (v6) WUs changed to do 'more sensitive' search by a factor of two
- SETI@home v7 adds Autocorrelation search
'Autocorr count: 1' on your task:

Don't mind comparisons 'ref-AP6' vs 'result-2-AP7' - I think they will always be incompatible (will be just a coincidence if they match)

'FUDGE' is % of allowed "uncertainty" (I think it is 1% - THRESHOLD_FUDGE = 1.01)

From ap_validate_inc.h (in ...\APbench\Tools\rescmpAP\src.zip\)
/* don't consider mismatches between pulses of power below * threshold*THRESHOLD_FUDGE as errors.*/ static const float THRESHOLD_FUDGE = 1.01f;


At the end of the test there will be file in ...\APbench\Testdatas\ with a name like:
ComputerName-20140802-0548-benchAP.txt

Look for 'Quick timetable' at bottom of that file.

The CPU test was 74 seconds with the GPU tests around 5 secs.

:) "with WU : #ap_genwis.dat" is Not CPU/GPU test - it is only to generate .bin/.wisdom files (to be used in next real runs)

Is there anything at all that can be done about the heat that SETI creates?

You may:
- use better cooling
- use TThrottle


It is the application that generates the heat and you are one of the programming gurus so fix it already!

There is nothing to "fix" - any optimized computing will heat the computing device (CPU/GPU/...)

Try to encode a video in AVC (x264 codec)
http://avidemux.sourceforge.net/

Try a 'heavy' game

Try Linpack
http://www.xtremesystems.org/forums/showthread.php?201670-LinX-A-simple-Linpack-interface

(all the above will heat)
