21) Message boards : Number crunching : Can I further optimize multiple GPU calculations? (Message 1772388)
Posted 18 Mar 2016 by Profile BilBg
If I change CPU usage assignment, will it affect Run time?
And does it affect credit?

No and no

The <cpu_usage> is not used by (GPU) applications, they use as much CPU time as they need no matter what value you set for <cpu_usage>

<cpu_usage> is only used by BOINC - to decide if it should run less CPU tasks so GPU tasks/apps have enough free CPU

The value is "part of a CPU core" (1 = full core, .04 = 4% of core ("core" as a device))

So if you change <cpu_usage>.04 to <cpu_usage>.33 this will Not have any effect (for computer which have one GPU):
3 GPU tasks * 0.33 cpu_usage = 0.99 = (truncated to) 0
= BOINC will act "normally" - the same as if <cpu_usage>0.001
BOINC will Not run one less CPU task (will Not "free a CPU core") - will start/run as many CPU tasks as the number of CPU cores (threads) (if you "Use at most 100% of the CPUs" in Preferences)

If you change to <cpu_usage>.34 -
3 GPU tasks * 0.34 = 1.02 = (truncated to) 1 = BOINC will run one less CPU task (will "free a CPU core")

Any value 0.34 ... 0.66 will free 1 CPU core
0.67 will free 2 CPU cores (for 3 GPU tasks running)

Free CPU cores may/will affect Run time for GPU tasks and so affect credit/day

Sadly I even don't know what CPU usage of 0.4 means, i.e., is this the upper limit, average, time, threads or something else?

Again - the applications don't know what you use for <cpu_usage>, only BOINC knows
BOINC can't restrict GPU apps by "upper limit, average, time, threads" - once the app is started it uses CPU GPU RAM ... as it needs

So CPU usage of 0.4 means (is hint) for BOINC that one running GPU app will need 40% of a CPU core ("thread" (virtual CPU) if you use Hyper-Threading)
BOINC sums all the <cpu_usage> numbers from the currently running apps
Then truncates to integer (1.99999 -> 1) and reduces by that number the started CPU tasks (i.e. instead of 4 will start 3 CPU tasks)

i7-3930K with 3 x GTX 670, <GPU_usage>.33, <cpu_usage>.04

For this system with 3 GPUs <cpu_usage>.4 will make BOINC to:
3 GPUs * 3 GPU tasks * 0.4 = 3.6 = (truncated to) 3 = BOINC will run 3 less CPU task (will "free 3 CPU cores")

Also check the date/time of client_state.xml - it should be current (last minutes)
If the date/time is old - something is preventing BOINC to update the file
(The list of tasks and their state is saved in client_state.xml)

If this is the case - You can try to diagnose what is locking files by OpenedFilesView

Start OpenedFilesView - Options -> Enable Explorer Context Menu
Then Right-Click on BOINC Data directory -> OpenedFilesView

I tested that if I start scan by ESET NOD32 Antivirus on BOINC Data directory I can see how ekrn.exe opens files (in addition of what is shown opened by BOINC and applications)

Hi, BilBg.
I have looked in the file, but I am not familiar with the format and meaning of much of it. Are you indicating that the "can't parse scheduler reply" log entry means there might be one or more errors in that file?

If so, I will be happy to look for it and/or send you a copy of any portion you might like to look at. Just let me know.

Also, I completely disabled my Antivirus progam and even removed it's tasks via Task Manager before running this log debugging test.

Thank you.

"can't parse scheduler reply" should mean that something is broken in
(Or that BOINC can't read the file (locked by some program/Antivirus)?)

(I think) There are no secret numbers/passwords in that file so you may post it.
- the file should be at least a few KB (>4 KB, more if many tasks are listed inside)
- do you see "garbage" inside (random bytes and not normal text)
- do you see the start and end tags - <scheduler_reply> ....... </scheduler_reply>

The file generated by "my" BOINC 6.10.58 is in Unix format (lines end with LF only and not CR LF pair as is normal in Windows txt files (Hex bytes: 0A vs 0D 0A))

If you open it in Hex Editor you will see that:

The first 3 bytes in the file are: 3C 73 63
The last 3 bytes in the file are: 79 3E 0A

Notepad on Windows XP don't show properly the contents of such Unix format files. (I don't know how it is in Notepad on Windows 7)
Use WordPad to view it or in Total Commander - F3 View

Also you may open it in Notepad, Ctrl+A Ctrl+C
then Paste it here and use [Preview] button

The begin, middle and end parts of my file:

17/03/2016 12:44:56 | | Using HTTP proxy swanlb001:8080

The problem should be the proxy, can't you avoid it? (i.e. use direct connection)

Two ideas to try:

- see if VPN will help to Upload/Download (SecurityKISS is free for 300 MB/day, you only select server, no any complicated Settings)

- set HTTP 1.0 in cc_config.xml

Set this flag to use HTTP 1.0 instead of 1.1 (this may be needed with some proxies).

<cc_config> <log_flags> </log_flags> <options> <http_1_0>1</http_1_0> </options> </cc_config>

Posted 17 Mar 2016 by Profile BilBg
Should I simply go to the "Current Driver Download" for 64-bit Win7 in the bottom table?

I will suggest No
You GPU is a few years old model and the last "Current Driver Download" may:
- work slow
- not have a OpenCL part (= will not be able to do calculations/Computing)
- may not work at all
- may even refuse to install

(I'm on Windows XP and for my AMD ATI Radeon HD 6570 I use Catalyst 11.12)

Your driver 1.4.1417 corresponds to Catalyst 11.6
Older Catalyst versions (<11.12) are listed on "full version list":

On the page here your GPU is shown as what BOINC detected:
AMD Radeon HD 6200/6300/7200/7300 series (Wrestler)

What is the real/exact model?
If you don't know use GPU-Z or GPU Caps Viewer:

Is this GPU embedded in the CPU?:
AMD E-450 APU with Radeon(tm) HD Graphics

You may try Catalyst 12.1 (it have the minimum required driver "SDK 2.6")
The link is from "ATI Driver Version Cheat Sheet":

Old drivers before Catalyst 12.1 were deleted from the ATI AMD site ~year ago.
So if some driver works OK - keep the setup so you can re-install the driver in the future if needed.

In the Catalyst 12.1 setup (in CX132103.inf (the setup .exe can be opened by 7-Zip)) are listed these models for AMD Radeon HD 6200/6300

AMD68F9.4 = "ATI Radeon HD 6230"
AMD68E1.12 = "ATI Radeon HD 6230"
AMD68F9.5 = "ATI Radeon HD 6250"
AMD68E1.13 = "ATI Radeon HD 6250"
AMD68F9.6 = "ATI Radeon HD 6290"
AMD68F9.7 = "ATI Radeon HD 6350"
AMD68E1.14 = "ATI Radeon HD 6350"
AMD68DA.1 = "ATI Radeon HD 6390"

AMD68E1.23 = "ATI Radeon HD 6230"
AMD68F9.17 = "ATI Radeon HD 6230"
AMD68F9.18 = "ATI Radeon HD 6350"
AMD68F9.19 = "ATI Radeon HD 6350"
AMD68F9.20 = "ATI Radeon HD 6350"
AMD68F9.21 = "ATI Radeon HD 6350 Graphics"
AMD68DA.4 = "ATI Radeon HD 6390"

AMD68E1.26 = "AMD Radeon HD 6230"

AMD68F9.29 = "ATI Radeon HD 6230"
AMD68F9.30 = "ATI Radeon HD 6250"
AMD68F9.31 = "ATI Radeon HD 6290"
AMD68F9.32 = "ATI Radeon HD 6350"
AMD68E1.28 = "ATI Radeon HD 6350"
AMD68DA.8 = "ATI Radeon HD 6390"

AMD68F9.33 = "ATI Radeon HD 6230"

AMD68F9.34 = "ATI Radeon HD 6250"
AMD68F9.35 = "ATI Radeon HD 6290"

AMD9803.1 = "AMD Radeon HD 6250 Graphics"
AMD9805.1 = "AMD Radeon HD 6250 Graphics"
AMD9807.1 = "AMD Radeon HD 6290 Graphics"
AMD9802.1 = "AMD Radeon HD 6310 Graphics"
AMD9804.1 = "AMD Radeon HD 6310 Graphics"
AMD9806.1 = "AMD Radeon HD 6320 Graphics"
AMD9642.1 = "AMD Radeon HD 6370D"

But since now Catalyst 11.6 works (for display/games/graphics) your GPU should be supported by Catalyst 12.1

If you want to know which is the last good working driver for your GPU - ask in Number Crunching
27) Message boards : Number crunching : How do I get my video card to process more work units? (Message 1771474)
Posted 14 Mar 2016 by Profile BilBg
Can you tell me what this file and the individual settings will do specifically


The posted version will do one of the following combinations (only for GPU tasks):
2 SETI@home tasks (<gpu_usage>0.4</gpu_usage> so 0.4 + 0.4 < 1)
1 AstroPulse + 1 SETI@home tasks (0.6 + 0.4 = 1 GPU)
1 AstroPulse task (if no GPU SETI@home tasks exist)

<cpu_usage>0.4</cpu_usage> will do nothing:
as only 2 GPU tasks run 0.4 + 0.4 = 0.8 = 0 = no CPU core will be free
The sum have to be >= 1 for BOINC to run one less CPU task

I was able to get the K6-2+ to successfully complete a work unit under Windows 7. Since then, I've ditched Windows 7 and gone with Windows 2000 SP4 (much more usable on the old system - posting from it now, in fact). I have two questions/problems.

First, I managed to get one of the remaining version 7 work units, but the progress is stuck at 0.0% even after 13+ hours of run time. I'm using the exact same app_info, executable, and dll that I did under Windows 7 (see previous thread). The elapsed time continues to run but interestingly, if I exit and restart BOINC, the time starts back at 00:00.

The app is hang in 'Optimal function choice' routine
Read my posts here:

My words: "It happens in 30-40% at start/restart of tasks on my K6-2+ but only when it is booted in Windows 2000
When the same system runs in Windows 98 it never happens
The BOINC and SETI@home files are the same (same BOINC Program and Data directories used, same tasks continue to run)"

Second question is if there is any way to get the version 8 app to process on the 586 architecture? I tried modifying app_info to use the version 8 app with the older dll to no avail

I didn't try SETI@home v8 on that computer:

But looking in the Lunatics_Win32_v0.44_setup.exe (which have the stock SETI@home v8 CPU app inside)

From setiathome_8.00.aistub
<app_info> <app> <name>setiathome_v8</name> </app> <file_info> <name>setiathome_8.00_windows_intelx86.exe</name> <executable/> </file_info> <file_info> <name>libfftw3f-3-3-4_x86.dll</name> <executable/> </file_info>

So try yet another copy of the old DLL (libfftw3f-3-1-1a_upx.dll) renamed to:
In fact I will suggest to have 3 files (all are the same file, only names different)

(in case the DLL file try to open/call itself by its original filename (I had this happen with other DLLs (it was for some game I think?)))

Posted 13 Mar 2016 by Profile BilBg
This computer is still spending a significant amount of time on GPU tasks that then error off due to OpenCL level.

This "significant amount of time" seems to be (for your GPU/driver) only 5 minutes/task:

I'm surprised that there isn't a central list of specific drivers that are known to work for each GPU model

And who will make that list?

There is "ATI Driver Version Cheat Sheet" made by one of the users (HAL9000):

As you can see: "Cat 11.12 Is the minimum required driver for current applications."

I don't know what is your GPU model/OS - people which know technical details about driver versions best for a given GPU model/OS post in Number Crunching
30) Questions and Answers : Windows : communication with server (Message 1771396)
Posted 13 Mar 2016 by Profile BilBg
Every 5 min my PC contact the boinc-server.

And you can see the reason in Event Log (Ctrl+Shift+E) - maybe something like this:

13/03/2016 19:17:06 SETI@home Requesting new tasks for GPU

This (if BOINC will ask for work) depend on your two Settings for "days of work":
set on web: Computing preferences
or locally: Local preferences

Set e.g. 3+1 days and BOINC will ask for work maybe one time per day
BOINC will also report completed tasks in hour after upload

The question remains why you don't like "Every 5 min my PC contact the boinc-server"
What do you see as bad with that?

OK, I tried to find the "mysteries" behind 'URL of background image'
(I use optimized applications which have no graphics so I never used background image)

* 1) I set your 'URL of background image' (

After [Update] from BOINC Manager:
- in Event Log (you can find the lines in stdoutdae.txt or stdoutdae.old):

13/03/2016 13:24:43 SETI@home Started download of background_1457867983

13/03/2016 13:25:27 SETI@home File background_1457867983 exists already, skipping download

- New lines appeared in


- The file "Downloaded" was background_1457867983 and have zero size (0 bytes)

- the site ( have "bad" Certificate
- I tried to change from https to http but the site ( automatically changes to https

* 2) I set

File background_1457869042 was Downloaded with correct size/contents (identical to SETI_TREK.jpg)

* 3) To avoid the https error from I go to:

Click 'Web' on the first line ("Upload images:")
Copy/Paste to the box:
Click [Upload It!]

This generated the following 'Direct Link':

I used that link for 'URL of background image'
File background_1457869574 was Downloaded with correct size/contents

Moral: try to use http and check that background_xxxxxxxxx was Downloaded OK

* 4) To see the new background for running tasks: Snooze / un-Snooze (or any other way to restart apps)
- this "refreshes" init_data.xml (in 'slots') so the running/restarted apps/tasks will know about the change.
New lines in init_data.xml (which appeared after Snooze / un-Snooze):

Exiting SETIspirit,

and starting SETIspirit again
- generates new SETIspirit.ini with exactly the same "Garbage" lines in [BOINC Environment] section

stdoutdae.txt do not have any line with "Starting BOINC client"
(stdoutdae.old and stdoutdae.archiv have many such lines)

BOINC was running for a month (SETIspirit was not running)
During that time stdoutdae.txt reached the max (8 MB per my Settings) and was renamed by BOINC to stdoutdae.old
New stdoutdae.txt was ~700 KB and did not contain lines with "Starting BOINC client"

Starting SETIspirit in this condition revealed the issue.

Exit SETIspirit
Restart BOINC
Start SETIspirit again

- this "fixed" the issue as now stdoutdae.txt contain line with "Starting BOINC client" (and the next info about OS, CPU, GPU, ...)

What preferences do i have to set for Atlas and VLHC to only run one task per project, but simultanously?

You can try max_concurrent in app_config.xml

You will need 2 files app_config.xml put in corresponding projects' directory
<app_config> <project_max_concurrent>1</project_max_concurrent> </app_config>

If you want to be specific (for one app):
<app_config> <app> <name>Application_Name</name> <max_concurrent>1</max_concurrent> </app> </app_config>

You'll need to find and Copy/Paste the correct "Application_Name" (for ATLAS@Home and vLHCathome) from some line in Event Log (Ctrl+Shift+E)

It is shown when "Starting task ..." from a project between the words "using" and "version", e.g.:

"Results" seem to be something countable, but they don't appear to correspond 1-for-1 with work units. What is a "result"?

Only people at the lab like to call tasks "Results" (even if the task is still not sent to anybody)
See the explanations on the bottom of this page:

"Results ready to send: For each workunit, results are generated that are then sent out to individual users to be executed"

... should be read as:
"Tasks ready to send: For each workunit, tasks are generated that are then sent out to individual users to be executed"

But "Results returned and awaiting validation" are really "Results" - task was computed and Result file sent back to server

A "task" is one copy of the "Workunit", at least 2 tasks are generated from 1 Workunit so the 2 Result files can be compared - some computers are not reliable and produce wrong numbers (heat, Overclock, low voltage, ...)

All tasks from the same Workunit are identical data files.

This ERROR should be the same no matter if original or patched version.
(I remember similar reports ("Unable to make copy") also for SetiPerformance)

On Expert tab:
- check if BOINC Data directory is found OK (if not - set it manually)
- make manually and set some other Temp folder, e.g.:

Don't try [Run] before [Test] is OK
Better exit BOINC manually before using [Run] button

I changed Astropulse_V6 Astropulse_V7 in version: box.

I'm not sure if Astropulse_V7 will work, make it:

changes from V7 to 8 appear to have worked as it displays Seti V8

Again: the patch is only for SETI@home, it will not affect AstroPulse

So the next info is only for SETI@home v8 tasks (the first tab):

The "Seti V8" text is just the name of the tab, do not affect functionality.
The important part is to change the string setiathome_enhanced to setiathome_v8

BOINC Rescheduler searches for those strings (setiathome_v8 astropulse_v7) in client_state.xml

If all is OK - on the first tab using [Test] will show the number of tasks:
Total #

If you have SETI@home v8 tasks but all numbers after [Test] are 0 - the patch from setiathome_enhanced to setiathome_v8 was not done correctly.

As BOINC Rescheduler can be run from any directory it will be convenient to make some sub directories e.g.

You copy the Original .exe to Patch-2 and try again if needed.

The resulting string should be setiathome_v8 - Not SetiatHome_V8
Must end with 00 byte, Not spaces (which will look as 20 20 20 ... <- WRONG)
