2) Message boards : Number crunching : Fastest available HDD (2016/Jan)? (Message 1760305)
Posted 13 days ago by Profile [#1@SETI] Dirk Sadowski
I'm an old man and don't 'trust' SSD's. ;-)

The HDD should be for a gaming PC.

I know I can't increase the FPS with a faster HDD, but the reload (new area, next level) should be so fast as possible.

With a few online games it's important...
3) Message boards : Number crunching : Where to download a virusfree Windows 7 .ISO ? (Message 1760302)
Posted 13 days ago by Profile [#1@SETI] Dirk Sadowski
A friend bought an used laptop with Windows 7 installed.
He didn't got an OS DVD.

Now the laptop is infected with a few virus.
Avast can't delete all.

I followed a manual in the web how to reading out the product key.
It worked.

With this key I gone to the Microsoft website and inserted the key for to download an OS .ISO file.
The website said, key not accepted.

I searched the web and read at Microsoft I can just download if I have a 'full version' key.

So my friend have an OEM or SB version.

Is there (where?) a possibility to download a virusfree Windows 7 x64 (Home Premium Family) .ISO - and I can activate it with the 'OEM product key'?

Thanks.

No, no SSD recommendations, please. ;-)


AFAIK, the WD VelociRaptor 1TB (WD1000DHTZ) - was/is the fastest HDD (SATA3 connection).

I searched the web, it looks like it's not longer sold - at least I can't find an online-shop which sell this HDD still.


Which HDD is now the fastest (reaction/access time, data transfer) available HDD?
(I searched the web, but I'm not smarter now.)

With 1TB or max 2TB (AFAIK, Windows can be installed just on HDDs </= 2TB).


Thanks.

I myself wrote:
So a SSE4.2 app isn't available like last time for SAHv7?

If so, then a little note somewhere in the Installer that just SSE2, SSE3 and AVX apps are available (just currently, or will come the other in future?) would be nice. ;-)

Grant (SSSF) wrote:
It was mentioned in the opening post of this thread & the installer readme file.

In the continuing absence of Joe Segur (we wish him well, wherever he is), we have only been able to provide a limited range of CPU apps - SSE (not applicable to 64-bit platforms), SSE2, SSE3, and AVX. These have been compiled using Microsoft Visual Studio, and may not be as tightly optimised as Joe's wizardry with GCC 4.7.1. When one of the intermediate SIMD levels like SSSE3 or SSE4.1 is detected by the installer and selected, the SSE3 application will be supplied for v8 tasks, but the matching v7 legacy (AKv8c r2549) application will be supplied for cleaning-up leftover v7 tasks.


Hm, maybe the stock SAHv8 CPU app could run faster than the SSE3 opti CPU app (on a CPU which support SSE4.2)?

Posted 14 days ago by Profile [#1@SETI] Dirk Sadowski
I used the v0.44 x64 Installer.

In the Installer stay for Intel iGPU: at least driver 9.18.10.3257

In the Intel_driver_Installation_Readme_(64-bit).txt file stay something from (how to install): 10.18.10.3958

So this is irritating.

So I downloaded all new drivers for my board (but didn't installed it until now). Because the 10.18.10.3408 driver worked very well over 1 year.

On my PC the 10.18.10.3408 driver is installed, so the Intel iGPU apps of the v0.44 x64 Installer will work?


I checked the SSE4.2 app for SAHv8.
It installed a SSE3 app.
I unzipped the Lunatics Installer and saw there are just SSE2, SSE3 and AVX apps.

So a SSE4.2 app isn't available like last time for SAHv7?

If so, then a little note somewhere in the Installer that just SSE2, SSE3 and AVX apps are available (just currently, or will come the other in future?) would be nice. ;-)
Because as I saw just the SSE3 app I was confused and thought I did something wrong during Installer usage.
(So I did it a second time.
And then I unzipped the Installer.)

Thanks.

A big 'Thank you alot!' to all who were/are involved.

Windows 8.1 x64, GT730, 347.52 driver will work with all nVIDIA apps which are included in the 0.44 Installer?

Just SAHv8 CUDA or also OpenCL app is included for nVIDIA VGA cards?

Thanks.

(I ask before I start to use the apps from the Installer)
10) Message boards : Number crunching : At least which internet speed for online gaming? (Message 1758585)
Posted 19 days ago by Profile [#1@SETI] Dirk Sadowski
If everybody upload 80 kbit/s during online gaming (LAN party)...

If I would play World of Tanks, there play 15 against 15.

So then my PC get infos from 29 other PCs (where the others are, what they do and so on...).

This are 29 x 80 kbit/s = 2320 kbit/s infos, which my PC need to download?
But I have just 2048 kbit/s max internet connection.

I don't know how accurate the Windows 8.1 Task-Manager show the Ethernet speed.
He say (if the PC have a big download, e.g. an AstroPulse task) I have 1.9 Mbit/s, this are 1945.6 kbit/s.

Or, if 16 people play a game and each PC have a 800 kbit/s download, so:
15 = 800 kbit/s, then are:
29 = 1546.67 kbit/s

This could work.


I have set a limit in the prefs, that the PCs have just ISDN internet speed (64 kbit/s (Download) and 16 kbit/s (Upload))

If I look in the Windows 8.1 Task-Manager, Ethernet overview, then it's like (for one SETI@home task):
1 sec peak up to ~ 500 kbit/s, then 3 sec nothing, then 1 sec peak up to ~ 500 kbit/s, then 3 sec nothing, then 1 sec peak up to ~ 500 kbit/s - and the file is downloaded.

Is this correct?
In BOINC is shown a continuously download in the transfer overview.


I see now in BOINC of the four FuryX's PC, there are always tasks in the transfers overview, it's never empty.
The ISDN speed is maybe too slow, the PC calculate too fast. ;-)


Maybe I'll let it this way, and...
will buy e.g. the ZyXEL GS-108S v2, 8-Port (GS-108SV2-EU0101F) LAN switch.

It's a Plug&Play with Quality of Service (QoS) feature.

I connect just one LAN cable to the DSL router, at the end this switch (but to which port, the low, medium of high priority?),
at the two high priority I connect the gaming PC (parts are ordered, i7-6700K with GTX980Ti), and the other two PCs (FuryX's just for SETI, the other for daily use) to the low priority port.

If I don't play at the gamer PC and I surf through the web with the daily use PC, BOINC on the gamer PC download tasks (but just with ISDN speed), and the movie stream (lowest resolution :-( ) on the daily use PC is disturbed, in delay?

Thanks.

I have a dream, at least DSL50000 or DSL100000.
In the countryside Germany related to internet speed is really still a developing country (and this is the 'richest' country in the EU?). :-(

Additional...

I you would like to install a new driver,
you should uninstall the old one first and use DDU (Display Driver Uninstaller) for to delete old stuff which could hinder the new driver.

Strange.

Here is written:
AMD Radeon™ HD 8470, Radeon™ HD 8350, Radeon™ HD 8000 (​D/G variants), Radeon™ HD 7000 Series (HD 7600 and below), Radeon™ HD 6000 Series, and Radeon™ HD 5000 Series Graphics products have been moved to a legacy support model and no additional driver releases are planned.


Catalyst 15.7.1
or
Crimson 16.1 Beta
This driver is provided "as is"​ and will not be supported with further updates, upgrades or bug fixes.

It looks like it's a specially driver for non GCN series.

You downloaded the software from there?


MSI Afterburner is a well tool for ATI/AMD VGA cards.
If you like, try it and look the GPU Load.

Here is an interesting thread about: Radeon Software Crimson

Currently it looks like: Message 1754968
my guess is that 280/380/7990 are somewhat related and you can run multiple wu per gpu

my other guess is that 290/390/fiji are related and cannot run multiple wu per gpu on current drivers without errors

with 290x i was able to roll back driver to 14.4 and run multiple wu per gpu but it wasn't very fast. it seemed faster to just use a more recent driver and run just one wu per gpu

i tried running 390x with 14.4 but it doesn't work, either driver too old or card too new


On my FuryX's PC I have Crimson 16.1 installed, same driver 1912.5 in it like in Crimson 15.12, until now not tested if 2 WUs/GPU would be possilbe with the newest one.

I guess, you could install Crimson 16.1 and let run multiple WUs/GPU on your HD6950 (if it's identical to the 280/380/7990 series).


AFAIK it have to do which Graphics Core Next (GCN) version your GPU is/have.

Which driver software you have installed?

Old Catalyst or new Crimson, which version?

In your PCs/results overview stay 1800.8, so I guess it's Catalyst v.x?

In your setiathome.berkeley.edu project folder should be a file like mb_cmdline_win_x86_SSE2_OpenCL_ATi.txt (currently I'm at my non AMD/ATI VGA card PC. ;-)

Open it with Notepad (german OS: Editor) and insert:
-hp
...save and exit.

This will give the GPU app more priority (high).

I would test it first just with 1 WU/GPU, then with 2 WUs/GPU and so on... - not to overload the Duo CPU.

Posted 20 days ago by Profile [#1@SETI] Dirk Sadowski
I looked in the web about - now I'm not smarter.


At least which internet speed (for download and upload) is needed for successful online gaming?


I have just DSL2000RAM (more is here not possible),
in the contract stay it's [min-max] 384 - 2048 kbit/s download and 64 - 384 kbit/s upload.


(BTW. If I have (maxed out) download, the upload speed would be affected/reduced then - and vice versa?)


My DSL router say, currently connected with:
Downstream 2302 kbit/s
Upstream 539 kbit/s

What does this mean, how much % I must subtract for the real existing speed to my next distribution node (in Germany we say 'the last mile')?


Thanks.

How will Intel fix this CPU bug?
In the BIOS is then an option to disable AVX?

No, the BIOS loads new Microcode in the CPU at boot time (this new Microcode will change how the CPU do AVX instructions internally, probably no speed change but only "correctness" of AVX instructions)
https://en.wikipedia.org/wiki/Microcode

probably no speed change ?

You mean a SAH or AP app which use AVX could be then slower than a SSE3 or SSSE3 app - because of the AVX bug fix?

Maybe I'll go with an i7-4790K instead of an i7-6700K (?) - short time and I'll order the parts of/for my new build.

The i7-4790K hava a TSX bug - maybe one day we'll have a SAH or AP TSX app?

Oh, maybe I'll go better with an unbugged AMD CPU? ;-)

the older...

It looks like since a longer time:

Number of tasks completed 6275


From my experiences, the really crunched tasks are ~ the double.


Make a forum search with 7374749 - that's the user which rescheduled AstroPulse v7 tasks from CPU to GPU.
