1) Message boards : Number crunching : Intel iGPU 'HD Graphics' and NVIDIA 'GT 730', recommendations for cmdline settings? (Message 1840367)
Posted 15 days ago by Profile Dirk Sadowski
Post:
I looked around and guess this should work with the Intel_r3541 and NVIDIA_r3584_SoG app... - or?

...for the iGPU 'HD Graphics':
-cpu_lock_fixed_cpu 3 -low_perf -spike_fft_thresh 2048 -tune 1 2 1 16 -hp

...for the 'GT 730':
-cpu_lock -instances_per_device 2 -total_GPU_instances_num 2 -use_sleep -high_prec_timer -low_perf -sbs 128 -spike_fft_thresh 2048 -tune 1 2 1 16 -hp

On the iGPU just 1 WU/GPU, and the GT730 with 2 WUs/GPU?

Maybe someone with similar hardware made bench test runs and/or have experiences which cmdline settings work fast/best?


Until now just 1 (AP&MB) WU/GPU on the iGPU and 2 (AP_OpenCL&MB_cuda50) WUs/GPU on the GT730.
Cmdline settings for AP (after bench test runs):
...for the iGPU:
-unroll 5 -ffa_block 1472 -ffa_block_fetch 368 -tune 1 64 2 1 -oclFFT_plan 32 8 256 -cpu_lock_fixed_cpu 3 -hp
...for the GT730:
-unroll 9 -ffa_block 896 -ffa_block_fetch 448 -tune 1 16 4 1 -oclFFT_plan 256 32 64 -use_sleep -cpu_lock -instances_per_device 2 -total_GPU_instances_num 2 -hp


Thanks.
2) Message boards : Number crunching : Driver Restart History? (Message 1840355)
Posted 15 days ago by Profile Dirk Sadowski
Post:
(With good luck) I was in front of the screen and at my PC with Win8.1 x64 popped up a speech bubble, that the driver of the Intel iGPU (HD Graphics) failed and restarted.
In BOINC was running a *guppi* (without .vlar) on the iGPU (with outdated r3330 app (maybe bad cmdline settings?)) and stalled at ~ 1/5 or the normally calculation time of a normally AR WU.
IIRC it was the first time that the iGPU calculated this kind of WU.

If I'm not in front of the screen and driver restarts happens, where I can see a history of (Intel, NVIDIA, ATI/AMD) driver restarts (at Win8.1 x64, Win8.1 Pro x64 and Win10 Pro x64)?

Thanks.

Thanks.


I seen a problem where I had to tick off SETI@home v8 "YES" to get work on my Ubuntu box, even though it had Accept Other Work and was working fine before.

Thanks for the idea.

I changed:
Run only the selected applications AstroPulse v7: yes
SETI@home v8: no
If no work for selected applications is available, accept work from other applications? yes

- to:
Run only the selected applications AstroPulse v7: yes
SETI@home v8: yes
If no work for selected applications is available, accept work from other applications? yes

- and my PCs get again WUs.


Still the same...

Is this BUG reported to the admins?

So many messages here in this thread (currently 239) - I'm sorry I couldn't read all (with my poor english (and because of this new website style))... - maybe someone other wrote this below already?

It not longer make fun to read the forum.

Black background and white letters...?
This isn't good for the eyes...
It make very tired after very short time.
It's hard work for the eyes...

I read the forum ~ 10 mins and now... - I don't know how to describe - I need to go away and relax my eyes...

Example, why amazon sell the 'Kindle Paperwhite' ebook reader (white background black letters)?
I guess it's very good for the eyes...?

OMG - the website style currently is so terrible.

If it's absolutely needed to have this style, please, please, PLEASE - give us users the possibility to choose different styles!

White background and black letters is the best for the eyes to read.

I have to leave now - I got headache...

11) Message boards : Number crunching : Linux CUDA apps on a Windows OS PC? (Message 1814169)
Posted 31 Aug 2016 by Profile Dirk Sadowski
Post:
It's possible to let run the SETIv8 Linux CUDA apps on a Windows (8.1 & 10, x64) OS PC?

(AFAIK, SETIv8 CUDA 6.0 and 7.5 apps are around.)

If, how?

Maybe with help of the BOINC/VirtualBox combi?

Or I would need to make a "Virtual (Linux) Machine" in Windows?

I have no experiences in this area.


BTW.
My GT730 with 347.52 (Windows 8.1 x64) driver can do CUDA 7.0.
A newer driver would help to let run CUDA 7.5 apps?
Which would be the minimum driver?

Or a (which) Linux driver would be needed?


(Currently I prepare an other/new PC with GTX980Ti, Windows 10 Pro x64.)


BTW.
The Linux AstroPulse CUDA or OpenCL apps could be faster in a Linux VB/VM in Windows than the Windows OS/Windows apps combi?


Thanks.

15:15 - Die UFO-Akten: Unterirdische Stuetzpunkte
Als ein Ingenieur das Gelaende für eine neue unterirdische Militaerbasis erforscht, geraet er in ein Gefecht mit Ausserirdischen. Er überlebt und erliegt kurz darauf einem mysterioesen Tod.

16:10 - Die UFO-Akten: Star People
Im Januar 2009 erblickt eine Familie im groessten Indianerreservat der USA ein UFO am Himmel. Als es direkt vor ihrem Haus landet, geht der Großvater hinaus, um sich mit den ausserirdischen Wesen zu unterhalten - mal wieder. Doch was verbindet die "Star People" mit den amerikanischen Ureinwohnern? Die Akten von MUFON, eine der groessten US-Organisationen zur Erforschung von UFOs, bringen erstaunliche Hinweise zutage, die historische Ereignisse in einem neuen Licht erscheinen lassen.

13) Message boards : Number crunching : Is it possible to swap a guppi assigned to GPU with a Arecibo assigned to CPU? (Message 1799221)
Posted 28 Jun 2016 by Profile Dirk Sadowski
Post:
I don't want to throw oil on the fire.

It was discussed in the forum many times, rescheduling and the resulting screw up of the Credit granting.

Each app have his own 'average processing rate'. E.g. the server send a WU to the GPU, will be calculated on the GPU, maybe 10 minutes. An other WU which was send to your GPU will now be calculated on the CPU (because of the usage of a rescheduling tool), the server (CreditNew calculation) think the WU was calculated on the GPU and is confused because it lasts maybe 5 hours.
You could find the related threads after a forum search.

I don't want to give much tips...
Fred's rescheduler is still available in his forum for download (he made this tool before CreditNew was installed here at SETI@home). He have also a warning near the download URL that it 'may result in less credits, for you or your wing man'.
And an instruction is available in this forum to upgrade the tool for SETIv8.

I was in E-Mail contact inter alia with Eric (SETI@home Director) - long time ago as CreditNew was installed here,
I asked why they don't write 'please don't use rescheduler' in the forum, Eric replied (from my remembering) something like 'that would do/change nothing'.

Maybe if you don't trust my statements, maybe you don't have the E-Mail address of him, here is she.

You don't need to create such a tool.

If you make a forum search with 'rescheduler' you will find such tool.

But, (after release of CreditNew) the admins aren't pleased about the usage of such tools, because it will screw up (the correct calculation of) the Credit granting for you and your wingmen (-> less Credits).

Posted 12 May 2016 by Profile Dirk Sadowski
Post:
I saw a TV show with inter alia Dr. Michio Kaku.

On his website you can read:
(...) So far, we see no hard evidence of signals from extra-terrestrial civilizations from any earth-like planet. The SETI project (the search for extra-terrestrial intelligence) has yet to produce any reproducible evidence of intelligent life in the universe from such earth-like planets, but the matter still deserves serious scientific analysis. The key is to reanalyze the objection to faster-than-light travel. (...)

(...) The current SETI project only scans a few frequencies of radio and TV emissions sent by a Type 0 civilization, but perhaps not an advanced civilization. Because of the enormous static found in deep space, broadcasting on a single frequency presents a serious source of error. Instead of putting all your eggs in one basket, a more efficient system is to break up the message and smear it out over all frequencies (e.g. via Fourier like transform) and then reassemble the signal only at the other end. In this way, even if certain frequencies are disrupted by static, enough of the message will survive to accurately reassemble the message via error correction routines. However, any Type 0 civilization listening in on the message on one frequency band would only hear nonsense. In other words, our galaxy could be teeming with messages from various Type II and III civilizations, but our Type 0 radio telescopes would only hear gibberish. (...)

(...) we are a Type 0 civilization, which extracts its energy from dead plants (oil and coal). Growing at the average rate of about 3% per year, however, one may calculate that our own civilization may attain Type I status in about 100-200 years, Type II status in a few thousand years, and Type III status in about 100,000 to a million years. These time scales are insignificant when compared with the universe itself. (...)

SETI project = SETI@home?


Which frequencies are searched through here at SETI@home and AstroPulse?
How SETI@home works.
It's still just a bit around 1420 MHz?


I don't understand very well what Dr. Michio Kaku mean. And Google Translator don't help much.
If I understood him 'correct', currently we can't find extra-terrestrial intelligence.
Maybe in a few thousand years with new/better equipment it would be possible?
My understanding is right?


What you think about this?


Thanks.
17) Message boards : Number crunching : GBT ('guppi') .vlar tasks will be send to GPUs, what you think about this? (Message 1784929)
Posted 5 May 2016 by Profile Dirk Sadowski
Post:
Here in the SETI-Beta thread I wrote what I think about this.

I thought a larger discussion (here) would be helpful.


I made my decision/statement...
Either...

  • an option in the project prefs for to un-/check 'GBT ('guppi') .vlar tasks to GPU' (so each member can decide to reduce or preserve the performance of the PC),
  • or I use a tool for to send GBT ('guppi') .vlar tasks from GPU to CPU (and screw up CreditNew),
  • or I search for a new primary project,
  • or I switch off my PCs.



Which opinion you have about the title/topic of this thread?

Thanks.

18) Message boards : Number crunching : 1.)MSI Afterburner doesn't start at Windows start up - why? 2.)FuryX downclock bug. (Message 1781590)
Posted 23 Apr 2016 by Profile Dirk Sadowski
Post:
MSI Afterburner (v4.2.0) doesn't start at Windows (8.1 Pro x64) start up...

I searched the web, but I'm not smarter...

(I need to start Afterburner with admin rights manually for correct function.
Until now I use this tool just for a 'better' fan curve.)

I check 'start with Windows' in the tool settings, but...
- or -
I check 'apply o/c at system startup' in the tool, but...
- or -
I copy a tool shortcut in the (*/normal_account/ (no admin rights)) 'Autostart' folder, but...
- or -
I copy a tool shortcut in the (C:/Autostart (admin rights?)) folder, but...
- or -
Over the task scheduler 'start at log on', but...

- it don't start automatically.

Why?

What I need to do that Afterburner start automatically?



Crimson 15.12 have a downclock bug (at least with my FuryX's).
Start of Windows and after a few minutes or a few days, one or two VGA cards downclock from 1050 to 300 MHz, up to 1050 again and down to 300 MHz again, and over again...
A reboot is needed to fix it... - to the time it happens again.

Crimson 16.3.2 have a 'power efficiency' point in the software (recommendation of the AMD support), I tested it 3 1/2 days and in this time the downclock doesn't happen.
I don't know if it fix the downclock bug, because sometimes it happen after 7 or more days...
But this software I couldn't use, because it make invalid AstroPulse results.


I need to use 15.12, but...
I checked in Afterburner:
disable ULPS
enabled force constant voltage

- and the downclock bug happens nevertheless.

Is there a way to make a work around (disable of power efficiency) that the FuryX's don't downclock?

Maybe in the registry (because I read here in the forum, that it's possible to disable ULPS there, but don't know how) or somewhere other?


Thanks.

The normal .vlar tasks lasts 4 times more, the *guppi*.vlar tasks lasts 3 times more - than a mid-AR task (on one of my four FuryX VGA cards) - (I'm a SETI-Beta tester).

If the AMD/ATI GPU PCs have good luck and get just this *guppi*.vlar tasks, their RAC will decrease /3, if also the normal .vlar tasks then the RAC will decrease /4. Not funny.

One of my FuryX calculate a (*guppi*).vlar task, in this time the card could calculate (3) 4 mid-AR tasks.

The nVIDIA GPUs don't get (*guppi*).vlar tasks...

It's not about Credits (only).
I (the most members here also) use the RAC for to compare (members/PCs/teams).

This would be like the AMD/ATI VGA card user do the 'dirty work' and the nVIDIA VGA cards are protected for them, that's like cherry-picking.
Fairness, equality?

If it ever would work, that the SETI server send the (*guppi*).vlar tasks to nVIDIA's OpenCL app and not to the CUDA app, the APR (average processing rate) of the OpenCL app will go so down, that the server 'use' just the CUDA app for the PC... with the result that no (*guppi*).vlar tasks will be send to the PC - or?


It's not possible to send the (*guppi*).vlar tasks just to CPUs?


I'm disappointed, I have set SETI in BOINC to 'no new tasks'.
I don't know when, or if I will set it again to 'allow new tasks'.
I'll follow the process and decide then...

I'm very sad (a hardcore SETIzen). :-(

I looked to other AMD/ATI VGA card PCs - if I looked correct they don't get the *guppi*.vlar tasks for their GPUs.

I set 'allow new tasks' again.

I don't know if it's really true what I saw... - if I'm wrong I set again 'no new tasks'. :-(
