I just wonder if the full 8GB can be used. And what kind of game you need for that. Although the new upcoming Deus Ex might be hitting it hard, nothing said about the likes of Doom 4, Hitman and maybe Fallout 4. Hope they don't expect me to play those with an Oculus Rift. :)

Of course, on the Fury X you pay for the high bandwidth memory, not so much for the water cooler. At 128GB/sec versus just 28GB/sec on GDDR5, that's no wonder.

Or Core Temp for the CPU temperatures, GPU-Z for the GPU thingamahoolies and for extra overload of data and control issues, Speedfan. The latter so you can quickly manually override any automated fan speeds.

Good God. Sapphire Tri-X R9 390X 8G D5:

GPU 2816 Stream Processors 28 nm Graphics Core Next (GCN) 1055 MHz Engine Clock ----------------------------------------------------- Interface PCI-Express 3.0 ----------------------------------------------------- Memory 512 bit Memory Bus GDDR5 Memory Type 6000 MHz Effective Memory Clock 8192 MB Size ----------------------------------------------------- System Requirement 750 Watt Power Supply (Suggestion) 2 x 8-pin AUX Power Connector


Price? About €475.-
Can't afford the 'X' version? There's also a normal version, also with 8GB. At about €370.-

For American prices, referencing this Powercolor review that says $450 for the X. (Edit: the other price I gave originally was for a 290x, not plain 390.)

6/28/2015 12:31:01 AM | | OpenCL: AMD/ATI GPU 1 (ignored by config): AMD Radeon HD 7500/7600/8500/8600 series (Devastator) (driver version 1642.5 (VM), device version OpenCL 1.2 AMD-APP (1642.5), 32MB, 0MB available, 2248 GFLOPS peak)

Your built-in AMD GPU is not used. By default BOINC only uses the best GPU, if you want to use more than that you'll have to tell it to do so via the <use_all_gpus> option in the cc_config.xml file.

So open up Notepad and add into it:
<cc_config> <log_flags> </log_flags> <options> <use_all_gpus>1</use_all_gpus> </options> </cc_config>

In Notepad click File->Save as...
Make sure the Encoding says ANSI.
Click the Save as type drop down menu and choose "All files (*.*)"
Put the path to the BOINC Data directory, in your case to D:\boinc data\
Click Save.

Next exit BOINC (open BOINC Manager->File->Exit BOINC Manager, check "Stop running tasks when exiting the BOINC Manager"->OK), and restart it again (normally Start->All Programs->BOINC->BOINC Manager).

If done as given above, this will make sure that BOINC will now use both AMD GPUs. The restart of the client is needed, because GPU detection decisions are only done at the client's start. A simple "Read config files" doesn't do anything here.

You can reserve a CPU core for CUDA, always a good idea. The value option does not allow for it to do fractures though, so you'll have to add the correct percentage there, 92%. The value is an integer, so round up or down to the nearest full value.

My boinc prefs are set to 0, 0 for cpu usage (0 being no limit).

Set values to 100, just to be sure there's no bug in the client (in some there is).

Setting CPU Usage to zero should suspend activity, because with that setting you're throttling BOINC.

Yeh, there was a change in the logic around the way the number is handled, it caught me out too.

The "On multi processor systems, use N% of the processors" (now Use at most N% of the CPUs ) has always been an integer.

90% on a duo core is one core.
90% on a quad core is three cores.
90% on an octo core is seven cores.
90% on a 128 core is 116 cores.

My driver is: NVIDIA GeForce GTX 460 (768MB) driver: 350.12 OpenCL: 1.1

NV driver 350.12 is OpenCL 1.2

The OpenCL version shown in the GPU detection is the one that the hardware supports at maximum, not the one that the software can add. Compliance versus compatibility.

Since Nvidia stopped support development of OpenCL in favor of their own CUDA, all of its GPUs will at maximum only hardware support OpenCL 1.2, until they start development of OpenCL again (if ever).

The GTX 460 was available in the OpenCL 1.1 era, it can get drivers that support 1.2, but will only do 1.1 via hardware.
Just as the GTX 980 will only do at max 1.2, even while it's been developed and released during the OpenCL 2.0/2.1 era.
You can compare these compliancies to DirectX. You can have a DX9c compliant videocard but an OS that runs DX11. The videocard will still only support DX9c, not magically upgrade its hardware to be compliant with DX11.

LOL at the comment "Why so much ram? Just load small sampling at a time and process that in a loop."

Apparently this person wants the near time persistency checker to run at anything but near time. Anyone want to explain to him how big the database is these days and that you don't just load that so fancifully in low amounts of RAM?

I don't think that the Linux science application comes with a pre-built graphics application. You should probably be able to build ones yourself when using the source code.

calculation of 90W per laptop & 200W per computer

The problem here is that off that 90W or 200W, you're using only a small amount for the calculation of the actual science and therefore you'll need to measure very precisely how much energy a Seti task takes. Which means that you'll have to deduct the electricity used by all the other hardware at the time being used, because it isn't being used for the science.

This means that every time the OS writes something of itself to disk, that you cannot add that electricity use to the science. USB ports, hard drives, optical drives, audio cards, speakers, monitors, game controllers, the keyboard, the mouse, memory, the operating system, all the other non-BOINC and non-Seti programs that run on the computer. All use electricity that you cannot add on to the electricity being used for the science.

When doing work on the GPU you have to divide what of the electricity is being used for calculations of the science, from what's used to draw everything on the monitor(s). Moving the mouse and touching the keyboard uses extra electricity on the CPU, but neither is used for the science. Even at idle the computer uses electricity, that you cannot count towards the science.

You can't ask of the project to calculate the electricity use either, as that would mean they'd have to get every kind of computer combination known to man in house and measure them all, something that's undoable for a shoestring project. Nothing said about the amount of man-hours that that's going to cost, that you aren't paying for.

I just sent Fred a private message, because he's wasting work by the hundreds, as he's using an AMD GPU with Catalysts 11.11, where 11.12 are the minimum required. So sad people don't ever look at their system, to check what it's doing.

Posted 26 days ago by Profile Ageless
I cant see a problem with the USERS id being undisclosed as long as its not permanent, it should only happen in special circumstances with the approval of S@H staff.

Not just available as an option anyone can choose willy nilly.

I think the staff has more important things to do than decide whether or not a person asking to be hidden to be able to run work on new alpha-hardware can have his request granted. Aside from that, time zones. A person in Japan may not want to wait 20+ hours for approval of something that shouldn't be a problem in the first place. And what about vacations? Staff on vacation, person will have to wait 3 weeks plus for approval, in this electronic day and age? Next you demand that people write in their request through snail mail to the Berkeley P.O.box or use a pigeon carrier. :)

Even if there's only a handful of users that are testing certain hardware or software, they should be allowed to decide for themselves and given the option to hide their names. And as said, in case of gross wrong-doing, the staff can reach them because they can read the person's email address. If that's at least an existing address, because anyone can make an account here and fill in a non-existing email address. But even then, the administrators can disable the account quite easily.

Over at CPDN the admins work closely together with the board moderators. When someone finds another user is wasting models by the tens, hundreds and more, their hostID is given to the admin, who will block downloads to that host. That will always attract the attention of the user, who will then come complain in the forums or in PM to one of the moderators that he cannot download work. After which he'll be told that his system has a problem, and that it's blocked until he has had time to fix his problem. And only when he has done so and shown he has done so, will his hostID be allowed to download work again off that project.

That's something the staff here could do as well. It's friendlier than many of the other solutions, and still allows the user to stay anonymous if he wants to be.

Frankly I don't know why anon users are permitted, when summat goes wrong they cant be told to check or whatever.

The project admins can always check their email and if necessary send them a warning through there.

Being hidden can be useful when you have certain alpha- or beta-hardware that you want to test using the project, but do not want to advertise. The hardware is still visible to anyone coming across the account, but without a name on it you cannot see who's using this hardware.

People testing such hardware will have to sign a Non-Disclosure Agreement (NDA) that states that while you may use the hardware for anything you want, you will also do everything in your power to hide from the world that you are testing this unreleased and unannounced hardware. And as such, at projects you can set to have your computers shown or not.

Both my PC and laptop have the update KB3035583 installed. Both machines report that the update is 'Recommended'.

I know now what the problem here is, Rick, one of anticipation and perspective. This update shows only in the Optional window, not in the Important window. The update is optional, but apparently one must see from the italics that the text is in, that this is a recommended update. You only see in its description that it is a "recommended update" after choosing it. I expect recommended updates to be in the important window, not in the optional window.




@Grumpy Swede
I will just let that icon sit there, and see how they plan to remove it for those that do not want to upgrade :-)

Easily done, uninstall KB3035583 and the icon goes away.

Check Jason's answer in this thread.

That's recovery from a failure during transfer of gaussfit results from the VRAM back to the host.

If it only happened the once, or extremely rarely, I wouldn't worry about it. The temporary exit did what it could to back out and try again, hopefully saving the result from some spurious problem.

If it happens more often, then you'd be looking at a range of possible issues from disk integrity through drivers into some hardware fault.

What actually caused that particular glitch, assuming ordinary consumer grade equipment like the rest of us, could be just about anything, including one-off spurious glitches, from temperature induced, [some other application messing with the GPU or system at the time], some immature system driver, even through to radiation in the silicon chip packaging material.

That's why enterprise gear with ECC RAM with Tesla compute cards, redundant PSUs etc exists... but for me a little bit of fault tolerance is more practical ;)
