....which leaves the user at the mercy of the reliability of your internet connection.
Oh, didn't I copy that? You get a Gigabit connection to their servers with the subscription....


No that is their outgoing bandwidth to you, it does nothing for your home connection.

Do I need a fast connection?

We recommend a minimum of 15Mbps, so a DSL, Coax or Fiber connection works perfectly fine. Shadow automatically adapts to the available bandwidth. You can use the Shadow apps on Windows, macOS and Android via Wi-Fi or even 4G.


The fastest connection I have available is 10Mbps and it has a very bad habit of playing yo-yo with my internet.

I have decided to give up on my W10 box. It is an I5 w a GTX1060. The mouse keeps getting broken after updates. I am only doing security updates. In the past I have been able to get it back, now it seems to be determined to stay away.
I would like to replace the HD w a HD from a retired W7 OS. The box it comes from is a E5400 CPU w a GT430.
Is this doable and what caveats should I be aware of?
Thanx in advance for any help.

My local computer source "reconditioned" my Win 7 Pro SP-1 x64 HD from Original Prometheus, (Intel QX9650 @ 3GHz on a Gigabyte GA-EP45-UD3P MOBO), to run on New Prometheus. (Intel i7 7700K on a Gigabyte GA-Z270-HD3 MOBO.) I don't know exactly what software they used to do the reconditioning, (something from Paragon, I think), and afterwards I had to "Reactivate" Win 7 Pro. Once done, and Win 7 realized what hardware it was now running on, (being "too new for Win 7 to 'supposedly' run on"), Windows Update "broke" itself and REFUSES to get ANY new Updates EXCEPT for Windows Defender.

STILL, I was able to install MOBO related Software and Updates, including a "3TB+"-Drive Software Piece that will allow Win 7 to recognize HDs and SSDs above 2TB. Even though Windows Update is now "blocked", all seems to be running as it should.

[EDIT:]

Also, had to install the Gigabyte MOBO USB-3 Driver for Win 7. Win 7 does NOT natively recognize USB-3.


TL


That will probably be me eventually, as I replace the guts of my primary computer with Rizon comaptible ones and keep the same OS.

If anyone tried to reach my site today and all you got was a blank page, I have gotten that problem taken care of, after looking at the error log and determining that I had a cache file screwing it up.

Time to start a new thread, because we are approaching 800 posts on #113.

I doubt if enough people would go the trouble of hoarding results to report. I think people just let BOINC run as intended. I put more weight on a cron job happening at that time that is more noticeable with the increased return rates during the contest.

Results returned per hour are presently less than they were before the WoW event started. The current lack of Arecibo work and the currently present longer GBT runtimes have brought that about.


Pendings are going up and valid is dropping.

All the 14au tasks I got seemed to take "forever" not run extra fast :(

Tom


. . If you take a look at the results for those tasks in the SETI database and look at the stderr info you will probably find they have lower than the "normal" AR of 0.44. The lower the AR, the longer they take.

. . I have had a look and there are no tasks for 14au for the machine with the single 750ti, but there are a lot of errors. I am guessing that was from when you had the SoG tuning parameters in your app_info. There are task results from 14au for the machine with the two 750ti cards but the run times seem pretty normal to me.

Stephen

. .


Also if you are running the SOG app, it will take longer on Arecibo tasks than than the Guppi's, the CUDA app is reversed on those accounts.

12) Message boards : Number crunching : Buying a Supercomputer? (Message 1950662)

Hello,

I'd like to buy a "supercomputer" for the main purpose of contributing to research like SETI and medical projects. I'm also somewhat interested in using it for VR, because why not.

I have an approximate budget of 20-30k, and have a few questions:

-How wasteful of my funds is this? Would building my own Linux cluster be 2x cheaper? 5x?

-What computer should i buy to get the most bang for my buck? I was looking at the "Silverdraft Power Resolve Workstation"... but not sure if I could stretch my dollars further with a different computer.

-Does this invite a security risk? I was once told by a friend that having such a powerful computer can attract the attention of hackers who would like to take control of the machine for mining bitcoin or whatever else.

Thanks for the help!

C


Looking at that machine that they want $33,500+Tax for, I decided to price out the components and add a few other items as well.









I can build pretty much that same computer, add two 31.5" 4K monitors, and faster ram for a quarter of the price they want. Buy another of the same case, more GPU's and another PSU and you still will not be even half their price.

Those are running between 7 and 10 minutes on my 1070's.

I'm sure the servers will be down for a few more hours... <trips over LAN connection to Keith's computer pulling it from the back of the IO shield>

We need Raister for the answer on this. I'm more familiar with Nvidia and SoG. He would know about the ATI cards


Or Mike, as he was the primary tester for those apps.

And he has now posted.

So where did the "phantom" Arecibo tasks split today come from?
https://setiathome.berkeley.edu/workunit.php?wuid=3096329479


Looks like a new tape that was recorded either June or July.

But there is no tape from Arecibo listed in the splitter array.

That's why I called it "phantom" I have seen no Arecibo tape loaded in the past week. So was it stuck in the RTS buffer and finally came free?


I got some of those WU's as well.

Looks like I received 69 WU's across my two machines.

I think that is a 27 July tape, at least if I decrypt the ID correctly.

If SoG is for both AMD and Nvidia, could you tell me how to unlock that option for AMD cards in the lunatics installer?

As far as I can tell, the best option is the one labeled “HD5” and is appended with “sah” in the app name displayed in BOINC.

Simply, the lunatics installer does not give me the SoG option for an AMD card, it’s only under the Nvidia options, which my card is not....

For now it’s running the HD5 SAH app. WU times on the order of 5-7mins.

I took a more reasonable approach, assigned 0.5CPU per GPU task, and reduced it down to 4 GPUs.

7 GPU tasks were producing such serious CPU bottlenecks that run times were like 20-25 mins per WU


I just looked at the actual archive and it looks like the OpenCL_Ati_HD5_r3557 is the same generation as SOG app.

From looking at the archives, it seems the SOG app for AMD was slower that the HD5 app.

Just got a no tasks are available at BOINC startup. Weird.
[Edit] Hit or miss now on getting work. 3 - 4 requests get nada and then finally a request gets 20-30. Not enough to replace what is reported. Caches falling on my fastest crunchers.


Both of mine are slowly losing work as well.


Next 20
