Yes, it is "usual setup with BOINC manager" (boinc.exe is started by boincmgr.exe)

I don't know if coproc_info.xml is created (it may be created and then deleted?) - I didn't tested.
I just put coproc in SwiftSearch and no filename is found.

(by the way SwiftSearch searches in RAM the pre-loaded $MFT files.
So if you created new files (and want they to be found) use F5 in SwiftSearch to read again $MFT or restart SwiftSearch
If files are on FAT32 (usual e.g. for Flash drives) - remember to use "conventional" methods to find them.
)

I don't know if the same mechanism (second boinc.exe that detects GPU) is used on old BOINC 6.10.58
Searching for string <engineClock> in all files in BOINC Data directory (by Total Commander) finds info about GPU only in
sched_request_*.xml and init_data.xml files (which are sorta Tmp files so seems BOINC keeps this info only in memory):

BOINC 6.10.58 is running now on:

I used SwiftSearch which "Searches NTFS volumes almost instantly" (with the speed of Google)
I have 9 partitions on 3 HDDs (7 of them NTFS)

There is no install, only small exe you run:

. . So now the box is running the graphic which seems rather uninformative to me. I guess if something interesting occurs there will be a big spike in the middle of the 3D graph??

From top menu here:

The graph do not show all the calculations, maybe one in 1000 or 10 000 (?) else the computing will be too slow.

Posted 19 days ago by Profile BilBg
Post:
https://setiathome.berkeley.edu/apps.php

The applications (.exe variants) are only 3

opencl_ati_ - for all ATI AMD >= HD 4xxx
opencl_ati5_ - "normal" variant for all ATI AMD >= HD 5xxx
opencl_ati5_SoG - SoG variant for all ATI AMD >= HD 5xxx

Every one of those 3 apps have 3 <plan_class>es (for a total of 3*3=9)
http://setiweb.ssl.berkeley.edu/beta/plan_class_spec.xml

Driver version 13.1 is bad so the server have to avoid computers with Catalyst 13.1
http://www.hal6000.com/seti/boinc_ati_gpu_cheat_sheet.htm

The same app (.exe) may be sent to Catalyst 11.12 ... 12.10 (i.e. < 13.1) by <plan_class> ending by _sah or _SoG
and to Catalyst 13.4+ (i.e. > 13.1) by <plan_class> ending by _cat132
This way the bad Catalyst 13.1 is avoided.

<plan_class> ending by _nocal is to detect GPUs or drivers which do not report/support CAL (AMD dropped CAL in favour of OpenCL)

Note:
If BOINC supported something like:
<bad_opencl_driver_revision>108440</bad_opencl_driver_revision>

... the number of <plan_class>es could be reduced

We're not testing with the screensaver, but with the standalone graphics window.
From Boinc Manager "Show Graphics" or what it says on the button in English.

. . OK thanks, that settles it for me. There's the rub you see, in my BOINC manager that button is greyed out.

Just select a Running CPU task (isn't that obvious?)


From memory there is an option during install to use BOINC graphics or not and I am rather sure that I chose "not".
So I would guess that the only way to use them now would be to re-run the install. That would be too disruptive :(

BOINC screensaver is always installed. (in BOINC install directory and in Windows directory)
So you can see "BOINC" in the list of Windows screensavers.

The question "during install to use BOINC graphics" only changes (or not) the Setting in Windows about which screensaver to be used.

SETI@home screensaver (setigraphics_X.yy_windows_intelx86.exe) comes with the CPU applications (i.e. is Downloaded automatically by BOINC)
SETI@home screensaver is started directly by "Show Graphics" or the BOINC screensaver starts SETI@home screensaver.

After making the changes, did you do a project update from the manager? Otherwise, they won't take affect until Boinc makes a scheduler contact.

Yup ... still not standing still ... hummmm ...

Those parameters a passed to the app in init_data.xml (which is in 'slots')

<format_preset>Custom</format_preset>
        <text_style>Pillars</text_style>
        <graph_style>Surface</graph_style>
        <max_cpu>10</max_cpu>
        <grow_time>10</grow_time>
        <hold_time>5</hold_time>
        <graph_alpha>0.7</graph_alpha>
        <roll_period>0</roll_period>
        <roll_range>0</roll_range>
        <pitch_period>0</pitch_period>
        <pitch_range>0</pitch_range>
        <starfield_size>0</starfield_size>
        <starfield_speed>0</starfield_speed>
        <color_preset>Rainbow</color_preset>
        <start_hue>0</start_hue>
        <hue_change>1</hue_change>


This means the task/app need to be restarted to know of the change, e.g. by:
- Snooze / unSnooze
- Start another task
- Restart BOINC

. . For what it is worth I am running it now ... but I have BOINC set to NOT use the BOINC screensaver ... :(

You don't need to change anything in BOINC to test the BOINC screensaver.

Just go to the "normal place" in Windows where you choose screensavers.
You probably have selected now "Blank", select "BOINC" instead and set small delay (e.g. 2 minutes) to test it.

... whether the percentage specified in the cpu_usage tag applies to the entire CPU or just one core.

<cpu_usage>1</cpu_usage> informs BOINC that the applications will need one (virtual) core.

This is only used by BOINC to calculate how many (virtual) cores remain usable for CPU tasks (i.e. BOINC will start less CPU tasks).
BOINC sums <cpu_usage>x.y</cpu_usage> for all running GPU tasks, then truncates the sum (e.g. 3 * 0.33 = 0.99 = 0 or 2 * 0.77 = 1.54 = 1)

BOINC don't know (and is not interested) in physical CPU configuration - if OS reports "16 CPUs" it doesn't matter to BOINC if this is "2 physical CPUs x 8 real cores" or "1 physical CPU x 8 cores Hyper-Threaded to 16 virtual" or ...

Application itself don't know about or use this value.


Then Boinc is using more than five cores exceeding a limit placed upon it

1. BOINC is not "using" the cores
2. This is not "limit placed upon it"
3. BOINC do not and can't control (or even monitor) the resource usage of already started applications.

Numbers like "Use at most 99 % of the CPUs" and <cpu_usage>1</cpu_usage> only tell BOINC how many applications to start (which is the only "limit").

BOINC assumes that one CPU app will use one CPU (read this as "core") (unless the CPU app is declared as Multi-Threading )
and one GPU app will use what is declared by cpu_usage / gpu_usage
BOINC do not really measure the real "usage".

I see a file was created named stderrgfx.txt. I'm seeing entries like this:

shared memory segment missing

That is the problem.
Now someone who makes applications and knows enough about programming in Windows have to figure-out why "shared memory segment missing" on Windows 10 Creators Update.
(is this a bug made by Microsoft or is it some new change in Windows, e.g. "for security"?)

("shared memory" is used so the applications' screensaver can get data from the running application)

Go to SETI@home preferences

At bottom:
Add separate preferences for ... (choose any of home, school, work)
Change them the way you want e,g, uncheck "Use CPU"

Then go to the computer page (as your computers are "hidden" I can't give you link) and at bottom change "Location"

Do the same on other projects (but uncheck "Use GPU")

This "Use CPU" / "Use GPU" Settings control what to be Downloaded in the future.

Double-clicking on the graphics executable results in a black box (the command prompt) opening and closing immediately.

It is not really "command prompt" but the window of setigraphics itself.

If you want to play a little more (you can do the same on a "bad" and "good" Windows 10 system to see the difference):

For the next test I used v7 files as I have them, as you guess your filenames will be a little different.
I used Process Explorer to monitor and kill processes.

A)
- Snooze BOINC
- Make an empty directory (e.g. ...\projects\setiathome.berkeley.edu\SetiGraphicsTest\)
- Copy in it setigraphics_7.00_windows_intelx86.exe
- Start it (setigraphics*.exe)

On a "good" system (Windows XP) I see this and it stays open until I close it:



- Close setigraphics*.exe (if needed)
File stderrgfx.txt is created (the last 2 lines appear only after I close the window of setigraphics):

14:27:47 (3412): Can't open init data file - running in standalone mode
14:27:47 (3412): Starting graphics application.
Warning: unable to load JPEG file. File size=0
Failed to load 'user_logo'.
Failed to load 'background'.
14:33:03 (3412): Close event (WM_CLOSE) detected, shutting down.
14:33:03 (3412): Shutting down graphics application.


B)
- Copy 3 additional files:
setiathome_7.00_windows_intelx86.exe
libfftw3f-3-3_upx.dll
work_unit.sah         (this is any WU file ~356 KB renamed to work_unit.sah)

- Start setiathome_*.exe
Wait 1-2 minutes and see how some 4-5 files are created.

- Start setigraphics*.exe



- Close setigraphics*.exe (if needed)
- Kill setiathome_*.exe (by Process Explorer)

- UnSnooze BOINC

What happens if you manually start SETI@home screensaver?

- While some SETI@home CPU task is running (you see process in memory with name like setiathome_8.00_windows_intelx86.exe)
Go to SETI@home directory (<BOINC_Data>\projects\setiathome.berkeley.edu\) and start the SETI@home screensaver, name like:

If David Turner had used the email of this account on the link to "Claim your SETI@home Classic workunits" he would have seen:
- Date 19 Mar 2000 on his current account (Date is copied)
- "SETI@home classic workunits 3,764 - SETI@home classic CPU time 36,087 hours" on his current account (these numbers are moved)
- Both accounts will remain existing
- The old account will be with removed classic counts

I have witnessed all this several times in the past years while helping other users do the same as in this thread.
Unfortunately David Turner used the email of another account from 2004 which we were unable to see before the "merge" but I'm sure it looked "the same" as userid=85575 (only with different classic counts)

In the end - if you give me the email of userid=85575 - I can "merge" it with my account ("merge" means: "Date is copied" + "Classic numbers are moved")

Maybe the text from this link is more clear (that all Classic is converted and looks like userid=85575):
https://setiathome.berkeley.edu/sah_classic.php
"When we launched SETI@home/BOINC, we created accounts for all SETI@home Classic users, with their existing email addresses. Each account includes the number of SETI@home Classic workunits completed, the CPU time, and the start date. These accounts were not given passwords (i.e., they can't be accessed using any password)."

I have no idea of the email address

https://setiathome.berkeley.edu/show_user.php?userid=85575

Since that old account (userid=85575) was never used for BOINC you may try to merge it with your current account (userid=10469435) by just guessing your old email address (no need for it to be active or exist)

His Classic points are already added to that account, which is a BOINC account and as you know, BOINC accounts cannot be merged. The account may never have been used for BOINC, but that is a BOINC account. Most probably the OP's original Classic account that got transformed into the BOINC account.

userid=85575 is exactly "original Classic account that got transformed into the BOINC account" and that can be merged.
(No "Real" Classic accounts exist, they are all converted. If never used for BOINC they can be merged. He managed to "hit" another of his Classic-converted accounts from 2004)
