So that tells me your old account was never a BOINC-SETI account, but a SETI Classic account

He have 2 old accounts - one SETI Classic 2002 and one BOINC-SETI 2006 (and current account created ~10 days ago which was 2016 and now 2002)

This was clarified in this my post:
http://setiathome.berkeley.edu/forum_thread.php?id=80209&postid=1815148#1815148

The question was which of his BOINC-SETI accounts (2006 or 2016) to connect with the oldest SETI Classic 2002
He was trying to remember the password for the BOINC-SETI 2006 account.
Since he fast get more credit on the newest 2016 account than had on 2006 account this doubt was easily resolved.

It is not possible to connect/merge User ID 8411114 with your current User ID 10365107 because both are BOINC accounts.
In any case you have to choose one of them and abandon (not use) the other.

Okay, let me see if I understand this last point. If I finally remember my password for the Rosetta@home project where I have stats associated with my old BOINC account, if I earn a few more credits on my new computer, then change the Hawaii email address on that project to my current CFL email address and then accumulate more new credits for Rosetta on the same computer, it won't link Rosetta to my current BOINC account where I have been earning current SETI credits?

Very good explanation :)
If you do all that - "it" will "link" the old Rosetta account to your current SETI@home account (meaning: in "Your account" here you will see at bottom (after a few days) the old Rosetta account)
Also it will sum in your "BOINC combined" credit:
http://boincstats.com/en/stats/-1/user/detail/4258798/projectList


"It is not possible to connect/merge User ID 8411114 with your current User ID 10365107" means: not possible to merge 2 accounts on the same project
(people usually ask this because they want somehow to add the credits from 2 accounts on the same project but it is not possible)
The SETI@home classic is exception and is not really "merge", only transfer of date and separate list of "SETI@home classic workunits".


I could have sworn that I read in some post about having a common computer with multiple projects and/or emails will do some kind of linking.

Yes, if you use the same email on all projects.
That is why I say: "You obviously used the same email for all these projects"

The email is used in a hash formula (MD5 ?) to create your "BOINC Cross Project IDentifier" (which is not secret, i.e. is not password)
http://boincstats.com/en/stats/-1/user/detail/4258798/overview

The same email on another project will generate the same CPID so will "link" your accounts from those projects:

Posted 18 days ago by Profile BilBg
well, v8.12 doesn't work on "low budget GPUs" still!

I don't understand "still" (?)
Do you expect that somehow the app will change (in code) but still be marked with version 8.12 ??

If/when they (at lab) decide to change the app they are forced to change the version #, else BOINC will not Download the new app.
So only of you see something like 8.13+ it may be changed app (but not necessarily - sometimes they post new version to fix other things (e.g. distribution to "proper" hosts), not the code)
http://setiathome.berkeley.edu/apps.php

I think the code to fix "low budget GPUs" issues is already present in the current builds (r3500+) but Raistmer have to tell if Yes or No.

You can test by running "Lunatics v0.45 - Beta4" installer and selecting "SoG"
http://setiathome.berkeley.edu/forum_thread.php?id=79704&sort_style=6&start=0

Or wait (a few months?) for Eric to post some new version - which (the executable) will be the same or newer than what is in the above installer (r3500) but written by the same programmer (Raistmer)

As you can see what you run now (and call "v8.12") is:
"OpenCL version by Raistmer, r3430"

Posted 18 days ago by Profile BilBg
Nope, random will result in randon hangs on ATi hosts under CPU load

By "random" I mean - when all the "cores" are already used (i.e. 5th app starts when 4 already run on a 4 "core" CPU) - set affinity to "random"/any core.


And as I understand (please correct if wrong) Hyperthreaded CPUs grouped in adjacement ID numbers, that is, 0+1 - first real core, 2+3 - second real core and so on.

I think the same (yes). Applies also to AMD Modules in Bulldozer+
And even if the CPU have in fact real cores - this will probably "distribute" temperature/heating over different (non-adjacent) parts of the chip.


If so, scheme I wrote before (first fill all even, then all odd, then repeat) will provide most even distrubution amongst CPU device.

But apps end in not-predictable moments (e.g. some tasks end in 10-30 seconds (overflow)) and another app starts.
Maybe (for test) make some simulation - feed the algorithm with random times (ending/starting apps) to see how it "distributes" over time (on different # of cores and different # of apps - e.g. 5, 6, 7 apps over 8 cores)

Also the algorithm should work on CPU with odd # of cores (like mine AMD Athlon II X3 455)

dev builds:
- are first distributed as "alpha" between limited number of testers (I'm not one of them)
- then released for general (but Advanced) public as "standalone packages" (one app in .7z for manual "install") for beta test by everybody who feels as "Advanced user"
- then included in Lunatics installer and given to Eric Korpela to test on "SETI@home beta" site

Only after that they are "promoted" as Stock (distributed automatically here)

"Stock" you are running are the same "Lunatics apps" only a few months older.

fill even CPUs then switch to odd ones then switch to even again

If the current instance knows mask of already running like (for 8 "cores"):
10001001 -> 10 00 10 01
00110100 -> 00 11 01 00
10100010 -> 10 10 00 10

- group like above by 2 bits [ maybe by (mask & (3 << groupN*2)) ]

Select first group which is 00
Else select first group which is 01 or 10
Else all groups are 11 - select random?

Well, for particular task of managing CPU affinity I would need to know number of SETI OpenCL GPU tasks running on particular host.

I think your apps already "talk" to each other (?) (which can be used to count them)
Else how one instance knows which CPUs are currently "in use" (per CPU affinity mask of other running) to select the "next free" CPU for own CPU affinity mask?

BTW, SoG & sah WUs still DON'T WORK on low end graphic cards, like GT 520!

There are no "SoG & sah WUs", there are SoG & sah applications.
So which versions of SoG & sah applications do you run? Stock??

The current dev builds are at r3500+ so the apps are always on "drawing board".
Did you test anything newer than stock?

This is what I have for the classic Comcast hours from 2002:

User ID 1208361
SETI@home member since 6 Jun 2002
SETI@home classic workunits 51
SETI@home classic CPU time 2,554 hours

This looks like classic account never used for BOINC ("Total credit 0" and no computers ever in BOINC list)
https://setiathome.berkeley.edu/show_user.php?userid=1208361
https://setiathome.berkeley.edu/hosts_user.php?sort=rpc_time&rev=0&show_all=1&userid=1208361


This is what I have for Hawaii from 2006:

User ID 8411114
SETI@home member since 20 May 2006
Total credit 45,494
(I wonder if this includes previously merged classic credit.)

This is BOINC account never connected to classic ("member since 20 May 2006" - classic didn't existed in 2006, and no mention of "SETI@home classic workunits" # - and no, that # is never converted to credit)
https://setiathome.berkeley.edu/show_user.php?userid=8411114

If "User ID 8411114" was "already connected" to "User ID 1208361":
- Both 8411114 and 1208361 will have date 6 Jun 2002
- the list of "SETI@home classic workunits" will be removed from 1208361 and added to 8411114

So it is not possible that "User ID 8411114" is "already connected" to "User ID 1208361"


Try again:
You have to be logged in your current account (User ID 10365107) while clicking the link:
http://setiathome.berkeley.edu/sah_classic_link.php

Paste the email used for User ID 1208361

If this works - it can't be reversed! (i.e. you can't "unmerge" and try again from (while logged in) User ID 8411114)

If there is error message - Copy/Paste it here (removing/changing the exact email for the post)
(the error message can't say anything like "Hawaii account")


... hoping I can remember that old Hawaii password

I hope you already understand:
that "password" you need is the password for User ID 8411114, not the password for the email site (SETI@home server don't check if the email box/account exists)

Can you find/resurrect some of these old computers?:
https://setiathome.berkeley.edu/hosts_user.php?sort=rpc_time&rev=0&show_all=1&userid=8411114


...
Rosetta@home 41,392 0 19 May 2006
LHC@home 3,851 0 20 May 2006
Einstein@Home 84,103 0 11 Feb 2005
...

Every project have its own server and its own accounts.
You obviously used the same email for all these projects (the same as email used for SETI@home User ID 8411114) but the passwords for every project may be different.

It is not possible to connect/merge User ID 8411114 with your current User ID 10365107 because both are BOINC accounts.
In any case you have to choose one of them and abandon (not use) the other.

put it before the -high_perf -high_perc_timer

-high_prec_timer : Windows-only. Attempts to improve Windows multimedia timer resolution. May result in smaller Sleep quantum.
In turn this would allow finer-grain sleep with less performance degradation (if any) with -use_sleep option.

(I always wonder why people type cmdline switches instead of Copy/Paste from ReadMe ...)


Unfortunately the app don't tell e.g. "Unrecognised switch ignored: -high_perc_timer"
http://setiathome.berkeley.edu/result.php?resultid=5136314645


You can also search/scan/find in the .exe itself if some switch is present.
This is direct Copy/Paste from inside of MB8_win_x86_SSE3_OpenCL_NV_SoG_r3500.exe (as seen by F3 View in Total Commander):

-v Verbose level set to:%d
-v N incorrect option use:argument needed
-hp -HP -rtp -RTP -high_prec_timer System timer will be set in high resolution mode
-cpu_lock -CPU_lock CPU affinity adjustment enabled
-no_cpu_lock CPU affinity adjustment disabled
-cpu_lock_fixed_cpu -CPU_lock_fixed_CPU CPU affinity adjustment enabled, fixed CPU %d will be used
-persistent_threads


You can see e.g. that some switches are accepted in several forms (different CASE) like -cpu_lock -CPU_lock but other are not (-no_cpu_lock)

thanks guys, this page http://boinc.berkeley.edu/wiki/Computation_credit gives a description but I don't understand what it is meant by:

Recent average credit: The average number of Cobblestones per day granted recently. This average decreases by a factor of two every week.

especially the last sentence...

Your current account (userid=10365107) is gaining Credit very fast, in a few days it will have more credits than your older SETI@home/BOINC account (userid=8411114)

So the only thing needed to merge the oldest SETI@home Classic account to your current account is to click:
http://setiathome.berkeley.edu/sah_classic_link.php

... and paste your oldest email (@comcast) (you can just try any of your oldest emails if you are not sure which one was used)

This will give you:
- You original "Joined" date
- List of # and CPU time of SETI@home classic workunits in your account


Like in this account (rob smith):
http://setiathome.berkeley.edu/show_user.php?userid=226846

SETI@home member since 7 Mar 2003 (BOINC was introduced in 2005)
SETI@home classic workunits 4,653
SETI@home classic CPU time 30,622 hours

(This will not work if somebody already stolen your SETI@home Classic account since you posted the email in the forum
In this case there will be message similar to:
"Some other SETI@home/BOINC account is already connected to the Classic account"
)

Why you revealed your email addresses in Open forum?:
http://setiathome.berkeley.edu/forum_thread.php?id=69103#1273877


It doesn't matter at all if you "can't access anymore" your old email address, nor if that email existed at all.
(e.g. I have secondary "fake" test account with email address of the form 12345@777.999 and it is accepted by this site as login)

The only thing that matters is: was the old account here "SETI@home Classic" account or was it used for BOINC?

If the old account is "SETI@home Classic" - go to this link and just paste your old email address
(this will merge it to your current account - make sure you are logged in your current account while clicking the link):
http://setiathome.berkeley.edu/sah_classic_link.php

(You don't need any password for this to work)

But - Read the text at bottom after:
This will not work if:
...


If the old SETI@home account is BOINC account you can:
- remember/try passwords for the old SETI@home BOINC account (and use "your old email" string + the remembered SETI@home password (no need for email password))
- find your old computer/HDD which had BOINC installation - there is file in it account_setiathome.berkeley.edu.xml which have <authenticator> inside.

"Log in with authenticator":
https://setiathome.berkeley.edu//get_passwd.php


P.S.
I only now noticed you give some links but since they are not clickable I didn't see them:
https://setiathome.berkeley.edu/show_user.php?userid=8411114

This is BOINC account (so first method for "SETI@home Classic" will not work for it)
Find one of the old computers (to retrieve <authenticator>):
https://setiathome.berkeley.edu/hosts_user.php?sort=rpc_time&rev=0&show_all=1&userid=8411114

... or remember/try passwords for the old SETI@home BOINC account.


P.P.S.
It seems from your old posts that you have even older email
So:
- first try to recover your older (userid=8411114) SETI@home BOINC account (by above means)
- then, while you are logged in that older SETI@home BOINC account (which have more credits), visit the link for "SETI@home Classic" and paste your oldest email (@comcast)

Where have you found tasks run on a different GTX 560 ...

GTX 560 Ti was notorious to produce false signals (wrong computations) because of too high clock and/or too low voltage (as set by default in the video card factory).
I don't know if that is the same/similar for GTX 560

Your GPU seems to run at "Max clock frequency: 1660Mhz" (this is "shader/CUDA Cores" clock):
http://setiathome.berkeley.edu/result.php?resultid=5104724560

... which looks within spec:
http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-560/specifications
http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-560ti/specifications

But nevertheless you can try (for test) to (temporarily) Underclock the GPU and video memory and/or raise the voltage a little to see if that eliminates/decreases # of "Validation inconclusive"/"Invalid".

e.g. by MSI Afterburner
