This resolution divides the sphere into 2^26 (about 54 million) pixels...

The other (cosmetic) typo is that 2^26 == 67108864 which is not really "about 54 million"

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.

Post:

It is a matter of your Settings, my keeps 1 year:
(Currently:
history_long_CompName.cvs is 734 KB and have 3516 records
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>
	<spike_fft_thresh>N</spike_fft_thresh>
	<sbs>N</sbs>
	<oclfft_plan>
	        <size>N</size>
		<global_radix>N</global_radix>
		<local_radix>N</local_radix>
		<workgroup_size>N</workgroup_size>
		<max_local_size>N</max_local_size>
		<localmem_banks>N</localmem_banks>
		<localmem_coalesce_width>N</localmem_coalesce_width>
	</oclfft_plan>
	<no_caching>
</deviceN>

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

Is there a way to specify only using GPU0 (the Quadro), or deny intel work units automatically ?

To not get more Intel GPU work from this project - deselect "Use Intel GPU" here:

For Rosetta@home - probably here:
https://boinc.bakerlab.org/rosetta/prefs.php?subset=project

For POEM@HOME - probably here:
http://boinc.fzk.de/poem/prefs.php?subset=project


To Disable Intel GPU for all projects:
Use:
<ignore_intel_dev>0</ignore_intel_dev>
(0 == the first Intel GPU) in:

The process priority increase only applies to GPU tasks.

1) From cc_config.xml

"
<process_priority>N</process_priority>, <process_priority_special>N</process_priority_special>
   The OS process priority at which tasks are run. Values are 0 (lowest priority, the default), 1 (below normal), 2 (normal), 3 (above normal), 4 (high) and 5 (real-time - not recommended).
'special' process priority is used for coprocessor (GPU) applications, wrapper applications, and non-compute-intensive applications, 'process priority' for all others. The two options can be used independently. (New in 7.6.14)

It should have been a ball mouse (they were expensive at the time):

Not laser mouse:
https://en.wikipedia.org/wiki/Optical_mouse#Laser_mice

"As early as 1998, Sun Microsystems provided a laser mouse with their Sun SPARCstation servers and workstations.
However, laser mice did not enter the mainstream market until 2004, when Paul Machin at Logitech ... introduced its MX 1000 laser mouse"


EDIT:
I didn't understand the "Had a glossy finish with blue grid lines across it" refers to the pad.
So it was probably this "Early optical mice" (LED):

"infrared LED and a four-quadrant infrared sensor to detect grid lines printed with infrared absorbing ink on a special metallic surface"

With <cpu_usage>1.4</cpu_usage> you are asking BOINC to free 1.4 * 5 = 7 cores (of 8 your CPU has)
This may cause sometimes BOINC to refuse to start 5 GPU tasks if there are more than one "High Priority" CPU tasks (in danger to miss deadline)

On this computer with 5 GPU tasks (over 4 real FPUs) is probably better to not run CPU tasks.

Are you sure this <exclude_gpu> works?

   [<device_num>N</device_num>]
   [<type>NVIDIA|ATI|intel_gpu</type>]
   [<app>appname</app>]
</exclude_gpu>

Your project_URL is not correct

Better try <ignore_nvidia_dev> which is simpler.
You may ignore all except one GPU to see where/what the GPU load will be and then for next test change numbers:

Test GPU 0:
<ignore_nvidia_dev>1</ignore_nvidia_dev>
<ignore_nvidia_dev>2</ignore_nvidia_dev>
<ignore_nvidia_dev>3</ignore_nvidia_dev>
<ignore_nvidia_dev>4</ignore_nvidia_dev>


Test GPU 1:
<ignore_nvidia_dev>0</ignore_nvidia_dev>

<ignore_nvidia_dev>2</ignore_nvidia_dev>
<ignore_nvidia_dev>3</ignore_nvidia_dev>
<ignore_nvidia_dev>4</ignore_nvidia_dev>


Test GPU 2:
<ignore_nvidia_dev>0</ignore_nvidia_dev>
<ignore_nvidia_dev>1</ignore_nvidia_dev>

<ignore_nvidia_dev>3</ignore_nvidia_dev>
<ignore_nvidia_dev>4</ignore_nvidia_dev>

Also it is not known to me why do you need/want <process_priority>3</process_priority> (above normal) for CPU tasks

Also the relevant lines from Event Log (Ctrl+Shift+E) about BOINC GPU detection
and relevant lines from cc_config.xml where you did <exclude_gpu> or <ignore_nvidia_dev>

I think "the device # did change when I reverted to beta 4" is just some coincidence - if you mean that BOINC GPU detection changed and show different device # for the same GPU
