On the picture one 8,12 task shows 548MB and another - 447MB RAM usage

They are old Downloads - I had 2-3 SETI@home tasks when I installed Lunatics_Win32_v0.45_Beta6-for-SoG_setup
(one of them may also be partially done by both apps, I don't remember - but I have stderr.txt archived by BoincMonitor (to 30 days back) if you want me to find some info)


30 mins for VHAR looks quite slow

The last such task:
http://setiathome.berkeley.edu/result.php?result_name=05no09ad.29451.67.3.30.158_0


EDIT: and maybe that looked like memory leak issue actually not leak at all but just the room to keep all events for enqueued kernels. If so adding additional sync points will help both issues.

I forgot to post previously - if I restart a "normal" (non-VHAR) task at e.g. 50% when it may be using 300 MB RAM - the app starts at 100 MB again (and continues from 50% done) and do not "jump" to 300 MB so at the end (e.g. 95%) it uses less RAM than if run without restart.

... the new downloaded tasks were labelled:
<version_num>820</version_num>
<plan_class>opencl_ati5_sah</plan_class>



(transition from Lunatics_Win32_v0.45_Beta4 to Beta6)

BOINC 6.10.58 decided to sort by version_num and choose the highest?

MB8_win_x86_SSE2_OpenCL_ATi_HD5_r3557.exe
AMD Radeon HD 6570 - Catalyst 11.12
Windows XP

1) RAM problem
Is it normal for ATi_HD5_r3557 to use so much RAM?
It starts at 100 MB, slowly increases and ends in 400-700 MB depending on task (r3500 used to use 100-120 MB)
(Video RAM usage is OK - constant during run 230-270 MB depending on task)

This RAM usage increasing is visible in Process Lasso and is also recorded by BoincTasks:
https://s21.postimg.org/5etbuf8xx/Boinc_Tasks_RAM_r3500_vs_r3557.png


2) Checkpoints problem
On "Very VHAR" tasks this app almost do not checkpoint on my computer:
- I monitored "by eye" tasks with ar=103.05 and ar=12.63
- tasks run to completion in normal time ~33 minutes
- they do not checkpoint until last minute - files state.sah and boinc_task_state.xml are created only @ minute 32 and after another minute the task finishes
In these last-minute files are these lines:
<prog>0.10701535</prog>
<fraction_done>0.926736</fraction_done>

- in init_data.xml is the checkpoint_period set by me (and other non-VHAR tasks obey it):
<checkpoint_period>47.000000</checkpoint_period>

- during run (using BOINC 6.10.58) BOINC Manager and BoincTasks show (after ~8 minutes) fake frozen "Progress" of 86.9 % which stays the same till ~minute 32

- After the startup CPU-only phase (~13 s) the RAM usage jumps (in 1 s) from 100 to 520 MB and stays the same till the end

- if the computation is interrupted (e.g. by Snooze) the tasks restart from beginning as if run for the first time:

Don't know why you say my user name is 'religious'

On the other hand, when composing a post, the Rules do include:
No messages intended to annoy ... or to hijack a thread.
No messages that are deliberately hostile,... or insulting.

And you omit what not suits your "proof of innocence":

For me your usernames, signature, Profile are full with religion.
You don't have just one username:

This will annoy anyone that is atheist or have another religion.

The very long username makes the formatting of the web pages "broken":

And you try to spread that religion on many projects (of course unsuccessfully, such pushing-in-the-face is just (very) annoying)

From this page:
http://setiathome.berkeley.edu/nebula_web/persistent.php

"We use a resolution at which each pixel is about as large as a telescope beam.
This resolution divides the sphere into 2^26 (about 54 million) pixels, of which about 16 million are visible from the Arecibo telescope."

From code:
https://setisvn.ssl.berkeley.edu/trac/browser/seti_science/nebula/tables.h

// largest possible pixel#
//
#define MAX_PIXEL (2<<26)


I think 2<<26 == 2^27

e.g. 2<<1 == 4 == 2^2

I could and probably will as long as the certificate is the only problem.

If this means you are just afraid (and not have a technical problem (?) to choose [Proceed anyway] or whatever button exists in your browser):

This is general warning from the browser because it don't know what this page will do - e.g. will it ask for credit card info.

Page like this is mostly just text (and IMHO should be accessible by http but unfortunately changes automatically to https):
https://setisvn.ssl.berkeley.edu/trac/browser/seti_science/nebula/tables.h

On the warning page in Chromium 35 (SRWare Iron 35) there are ~20 lines of explanations but the main essence is:
"The site's security certificate is not trusted!"
"In this case, the certificate has not been verified by a third party that your computer trusts."

They (at berkeley.edu) self-sign the certificate (because else it costs money):
"
Issued to: setisvn.ssl.berkeley.edu
Issued by: setisvn.ssl.berkeley.edu

This CA Root certificate is not trusted because it is not in the Trusted Root Certification Authorities store.

history_CompName.cvs is 25 KB and have 113 records

How long does it take to load BOINCTasks with that many History records?

~5 seconds.

"History records" in the tab are for 7 days (for me that is 100-200 tasks)
The other 360 days (3500 records) are only read if you click a button on the toolbar.
BoincTasks consumes ~1 minute CPU time per day (0.1% (1/1000) of a CPU core)


I have mine trimmed down to 2 days because the default value caused it to load over many minutes.

I don't know what is "the default value" and there are many values and checkboxes on the screenshot.

2) since the cmd line applies to all cards, ...

There is special file you can create:
MultiBeam_NV_config.xml
... but I don't know if it is possible with stock apps.
If the app searches for it next to the .exe i.e. in SETI@home directory (<BOINC_Data>\projects\setiathome.berkeley.edu\) it will find it.
If the app searches only in current directory i.e. in slots\ the file will not be there.


From ReadMe_MultiBeam_OpenCL_NV_SoG.txt
"
For device-specific settings in multi-GPU systems it's possible to override some of command-line options via
application config file.

Name of this config file:
MultiBeam_<vendor>_config.xml where vendor can be ATi, NV or iGPU.
File structure:
<deviceN>
	<period_iterations_num>N</period_iterations_num>

where deviceN - particular OpenCL device N starting with 0, multiple sections allowed, one per each device.
other fields - corresponding command-line options to override for this particular device.
All or some sections can be omitted.

Don't forget to re-check device number to physical card relation after driver update and physical slot change.
Both these actions can change cards enumeration order.

Posted 28 Oct 2016 by Profile BilBg
Post:
Weird. So I aborted the 3 tasks that were suppose to use the NVIDIA GPU, updated my connection to the server, then it redownloaded 3 new tasks and now it's working properly.

Well, it probably only needed a nudge. :)

SETI@home v8 stock applications were updated to new version ~2 weeks ago:
http://setiathome.berkeley.edu/apps.php

With new tasks marked "SETI@home v8 v8.19 (opencl_nvidia_SoG)" (r3528) were Downloaded new apps.
I remember some posts about old apps (SETI@home v8 v8.12 (opencl_nvidia_SoG) = r3430) hanging on low-end GPUs as this GeForce GT 610

Like "Just wasted 3h on SoG two units from Arecibo on 600GF card, which were stuck on 0,001%!" (what he calls for unknown reason "600GF card" is NVIDIA Quadro 2000)
https://setiathome.berkeley.edu/forum_thread.php?id=79418&postid=1820463#1820463


This hang was fixed months ago (ask Raistmer when and what) but only now the stock apps were updated from r3430 to r3528
