Hello Eric, It's good to see you in here :)
I was looking a little bit ago, and the computer I seem to be having the most problem with doesn't have static DNS entries.
The other only drop a few connections, but eventually they go through on their own.
Hopefully they can sort it out.


Eric does know to look for the most recent Panic Mode thread, he is just a very infrequent poster.

Tom I was just looking at your 2700 Win 10 host with the 1060 3GB card. https://setiathome.berkeley.edu/show_host_detail.php?hostid=8671092

and I saw a SoG command line I had never come across before. I see you have defined 6 kernels instead of the standard 2 and that seems to really speed up the crunching. I wonder why that isn't in more use? Simply lack of exposure or commonality?
I'm with Keith, never seen more than one or two kernels defined.
Why did you choose six, and how do you determine how many kernels are in any particular card?

It helps if you read Raistmer's dissertation on what the tuning commands do.

Pay attention to his first post in the thread about -period_iterations_num N and how that impacts the number of kernel arrays you set up.


On my 1070's, this seems to have the best speed for them.

-sbs 1024 -period_iterations_num 10 -spike_fft_thresh 4096 -tune 1 64 1 4 -oclfft_tune_gr 256 -oclfft_tune_lr 16 -oclfft_tune_wg 256 -oclfft_tune_ls 512 -oclfft_tune_bn 64 -oclfft_tune_cw 64

Yes, even when plugging a USB 2.0 mouse into a native USB 2.0 port on the motherboard, Windows 7 still throws a fit when its installation probes the hardware and finds something strange it doesn't understand (the USB 3.0 hardware) and instead of gracefully ignoring it and moving on with the rest of the installation, it just throws in the towel and hangs or just quits.

You have to have the USB 3.0 drivers slipstreamed into the original Windows 7 media to get Windows 7 installed on Ryzen.


I actually booted to the previous install of Windows 7 and it would not recognize the mouse or keyboard.

That might have been the old thread then, as this one is only on page 9 for me.

....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.

39) Message boards : Number crunching : Buying a Supercomputer? (Message 1950662)
Posted 19 Aug 2018 by Profile arkayn
Post:
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.
