Also, some info about the database:

The database of diffraction patterns is offline since April because the data center at the Institute for Information Transmission Problems of RAS in which it is hosted (also, this center is a hosting provider for the Acoustics@Home, USPEX@Home, SAT@Home, Optima@Home, Boinc.ru and some other non-boinc resources) is powered off and in the middle of moving to a new location. As soon as the data center will be powered on, the database will be back online. However, moving the academic data center to a new location is a long process because a lot of bureaucracy involved.



Hello dear friend,
happy to have news from you. I hope all is ok at your side. Take care.
Still now, on some other projects, your name appears as example of winderfull admin.
Best and firendly regards from Brlgium.

This has probably been one of the best managed project I have ever had the honor to partecipate. From the beginning to the conclusion everything has been properly managed and delivered.
And congratulations on completing the objective the project had, sure, it is sad when a project closes, but if it is because we did our job and successfully completed it, then it's a great thing!



Hello Milleniu. Late message, but I am sure Vlad will aprreciate. I fully agree with you.
If Vlad start a other it ill be also wonderfull management.

Hello Vlad

I also have see the same as Michael yesterday.
Today (7th july 18:00 UTC) all is again visible.
Personal, team, users, forum, stats,...

Perhaps a very little bug.
Only "server status" is not more visibe.

So Michael, you can do it again. I have try. It works.

Vlad,
I think that when you will start a new project, you can axpect a real rush ....
It is the "reward / wanted" of all your wonderfull work...

Best regards everyone

Philippe

Hello everyone,
There are few thanks to Vlad who is, (I think), the best project admin.
Always anwser, and very fast, always to help,...

By this post, I hope as much as possible cruncher would say him "Thank you"

Vlad, is it possible to send ONE, only ONE WU by user ?
Of course without CR. Or perhaps only 0.01.
So the problems of many request will be solved !

On competition, it will nothing change. For sure with 0.01 CR.
Why ? Only for fun and help.

Vlad, I personaly think, by reading all posts here, you have our consideration.

Some cruncher known who I am. Also knows I am not always very "quiet", shouting loud sometimes.Here never. I am who I am.

But here on Xanson directed by Vlad, as deep as I can, I can not find negative point. No any !!!

It is why, i repeat, each cruncher would send Vlad his support
It is a way to say thank you and help him in his way of doing.

Sad, sad, sad,...

Now, we know why Acoustic is also not more reachable.
As far I know, nobody of it had warned us !

Vlad,
THANK YOU, a very very big THANK YOU for all you did.
My best wishes for your next work. I am sure, it will also be perfect.

Sad, sad, sad,...

Waiting next project, best regards

Hello Vlad,
I think, and the most of user users, knowns your efforts,
No only about WU but also to inform all of us. Very few admin do it.
Your way of do is an example.

About amount of WU, crunching time, computing power, you personnaly know what I mean....
Perhaps a solution : release WU hen you have. Not wait saturday.
So WU will be crunched and no bottleneck...
You have 10 COD, send it.
So not so may requests on saturday...
In one year , I have see the difference. also you.

The "problem" of Xanson, is only linked , or due, to the race on Formula Boinc.

Your WU are very fast returned, few credits, but the same for eveyone.
More and more users connects here because it take very short time.
Make your WU as long that they need several days , with the same credits,
you will never see bottleneck !
Look with CAS@home ! Little PRJ, very few WU,... never problem.

About your latest sentence, I not agree. There are much more project unable to produce work.

Then the worst who make me sad and very disappointed. Your idea to stop and close Xanson. Once gain I understand your point of view.
I am sure in your research center, there are other project.
Not leave to fast. You can set Xanson on pause, not

So Vlad, I thank you for all your work, efforts,...
Best kind and friendly regards with hope to not read closure of Xanson

Hello Vlad,

The answer is in the TCP/IP protocol.

To know how many packets there are in a single WU, it depend of kind of connection also ISP !!! Yes Internet Sevice Provider (see below)

IPV4 :
Usualy Ethernet TCP/IP use 1500 bytes (include protocol 20 bytes, ipv6 : 40).
Also called MTU
FDDI is 4470 bytes.

To make very easy/
Let us start that one WU is 1200 bytes.
So the WU can be inside one packet (1500-20)
If the WU is 1490 bytes, it need 2 packets.
One with 1480 real WU data and one with 10 bytes real WU data.
The 1470 free are unused.


Why also ISP ?
Some of them reduce the packet to 1488. Why, to have a multiple of 8 and 16 !!!
Considering here above and the size, if locally, you not adapt the MTU to the size of ISP, it need often a resend of the latest bytes of the whole "message"./
Of course, since many years and the power of network, it is not sensible.
In the far past with a 56Kbps connection, it was very usefull.

Considering the WU are not from the same size, you understand, it is very difficult to make a correct calculation of packet amount a single WU need.
And, imagine all WU are perfect the same, you will be able to know the amount of package.
But never the connections problems between your server and all users.
I mean lost packets, resend because corrupt,...

Best regards




3.000 host for 30.000 request/sec..... In the worst case : each user
need to make 10 request by second !!!.........

Sorry, I already made the correction in my post. It is actually 30.000 packeges/sec (this is what the AWS statistics says). I do not know how many packages are in a single work request but I'll try to find it out.

Hello Marmot,
I am a very active cruncher here. at least, I try.
With my hosts (six moderate hosts), I try to get as uch as possible WU.
With Vlad, and estimation, I alone, can crunch all WU in only 2 or 3 days. You also. I am sure. (I not mix COD and WU)

Vlad, have decide to make everyone equal.
By very strong limitation. I understand him.

You, probably like me, tou try to make manual update.
Also not forget up/down time and bottleneck
If you consider amount of host connected on PRJ (+/- 2750 actives) Let u say 3.000 (see below)

When Vlad speak about 30.000 request / second, you can understand that something is not normal. Not you, not me can make so much request by second !!!

3.000 host for 30.000 request/sec..... In the worst case : each user
need to make 10 request by second !!!.........

Impossible of course.


Then about you did not get any GPU, I suggest you read very, but very acrefully, the config.
It took me some months before I understood why. Now it is OK
On ATI RTX580, or 1060, or little GTX570.
All working.

Now this saturday it were less GPU WU as usual.

Best regards

Hello Vlad,
I hope you could adapt network !
If I look new registred users : 0
But new hosts in the past 24 hours : 207 !!!
It will say from the 141 recent users some have add a lot of hosts .
It will be very big bottleneck !
It increase release after release...

Ii will be a very hot saturday evening for your server !!!

I receive GPU !
Very few, as usual !
Never forget that this project has very few WU.
It is not a surprise. From beginning it is explained.

Also not forget for user who runs several project, to pause all others.
And to increase your cache for sure if you have a full cache.
And never forget the deadline of Xanson WU (usual 72 hours) !!!

If you have a cache of 4 days, already full for other project and you increase to 10 days, you will never receive from Xanson because deadline !
Unless you change manually your scheduler.

Yes Xanson is very sensitive. It is his "charm".
But required a lot of attention, precision and time to manage.

When I will publish this , probably will all WU be already sent !

A system with 50 logical AMD RX series GPUs is of course nonsense.

But if you spot a host with many big Nvidia GPUs, then a likely explanation for this is that its owner is also SETI@home participant and configured this pseudo number of GPUs in order to bridge SETI's weekly maintenance window. The people who do this don't want to "game the system", they merely want highest possible uptime of their compute clients. This directly benefits the SETI@home project, and I applaud these users for their dedication and ability.

Anyway; in case of XANSONS for COD with its low number of tasks per month, I can understand Vlad's choice for a simple per-host limit, instead of anything more complicated.



Hello xii5ku,
I see (read) I am not the only who agree with Vlad his way of doing.
Then you comparaison with SETI.
I am from past century on SETI. Everyone know the weekly outage.
Sometimes very long.
If I good remember in the latest 20 years on SETI, there were two main outage period. (I not count just after Arecibo "crash".

You applaude for such invest. OK if it is honnest.

So why to artificial mount 50 GPU. Like you say : nonsense.
It is abusing the system.

Look on SETI : host 8480062 !!!
Great : on one host 48 (fourty-eight) GTX1080Ti !!!
And running on a i7-6850K !!!
OK, Linux.
It only show virtualization.

I not write. It is not the place.

I only fully agree with your opinion about Xanson and the decision of Vlad

Best regards






But, evryone is free to download WU up to 10 days (on SETI)

Well, some of us do have 5 GPUs per host or more. Old mining rigs that I've acquired to crunch GPU projects instead of crappy mining are used. So 25 per GPU was nice.

Some hosts report 50 GPUs, http://xansons4cod.com/xansons4cod/show_host_detail.php?hostid=2356...
Of course, setting per GPU limit would not be a problem if the total number of WUs was not so limited.



Well well well.
50 GPU on the same host !
And tyhis host is managed by a i7-2600K !?!? The same as 3 from my hosts.
And this host have onlmy 8Gb RAM (also like me)The only possible is to run on several virtual machine.
But with only 8Gb RAM I am not sure to be able to run more than 4 VM together.
Then the "little" 2600K will not be able to follow and manage it

I want so mainboard able to manage 50 GPU !!!
And eventually the speed of the FSB (not "russian secret service" his new name of course) Smile.


I really would known the manufacturer and model of this mainboard able to manage 50 GPU. As far as I know, the maximum is four GPU SLI or Crossfire.
If it is a server, OK, but then 2600K can NOT manage and Win10 also not.
Where to buy ???

Yeah, those are evidently fake and gaming the system. I see your predicament with limited WUs. Thanks for the info.



Hello Bluestang
I can understand your frustration.
But I also fully defend Vlad.
Not forget Xanson have very few WU to crunch.
It is known from the start of the project.
Very clear.
The limitations give everyone a possibility to crunch.
Very few, I agree. But it is the same for everyone around the world.
After very fast calculation, with my weak host, I am able to crunch all WU
in only two days.
Yes, midrange host, can crunch all WU in only two days.

Before you accuse Vlad to fake and gaming, I suggest you read again the rules of this project !

Imagine instead of my weak hosts, I come with tenth of 64cores, all with 4x108Ti or better, All wu will be returned in a few minuts. And nothing for other. OK so far. For the project it is better.
Scientist are happy to receive results. It is the main goal.
The research increase. Also OK

But it is not the phylosophy of this project.

Vlad, try to give everyone a chance to crunch. Always very few by user/host.
I fully understand, agree and support his way of thinking. Everyone the same.

I personnally very like this project. I am also like you frustrated to not receive more than 25 WU.
But it are the rules. And Project admin have very clear explain why.

Then before complaints, you processed 2077 COD for a total credit of 2,781,024 CR (Situation on 09feb20:39CET

Personnaly I crunched 3797 COD for only 1,042,915CR (situation time the same) !

So please do not do not accuse admin (vlad) about "fake" or "gaming".

Personnaly, (but it is only me), I think he try to do his best for everyone.
Scientist are happy. The main goal.

Ranking .... is not important. Only for some who give more interest to ranking than to research.

So Bluestang, please reconsider your opinion (vision). For sure againt the admin

Hello,

The empty log indicates that the app just failed to start. Usually, this happens if the redistributables are not installed, but since they are this is not the case. Is there any chance that the app is blocked by the antivirus software?

Update. Did you install the x64 version of C++ redistributables first and the x86 version second? If so, there is a chance that the x64 libraries were removed when you installed the x86 ones. Microsoft released a fix for that, https://support.microsoft.com/en-us/help/3138367/update-for-visual-c-2013-and-visual-c-redistributable-package.



Hello,
I installed C++2017 x64 then x86 ! Like you wrote, the x64 was removed
Now I reinstal C++2013 x86 then x64.
The pitty is that I ne"ed to wait the next WU release to check !!!
Unless you have a CPU "test WU" that I can inject. (GPU is OK)
