Well the new (used) ram came in. And it seems to perform to spec except I haven't been able to OC past 3.6GHz.

I am still trying to sort out the range of cpu processing times. Ever since mix of tasks started including the ones with the dates in the beginning of their names I have to try to factor those out so they don't skew what I am trying to see.

What I am hoping to see is equal or better performance on at least some of my AMD 2990WX tasks as compared to my Intel e5-2690v2 tasks. I am running 1 hour and 6-12 minutes on the Intel. I am getting some tasks in that range or slower on the AMD with a lot more in the 1 hour 40 minute range. What I am not seeing, so far, is tasks processing faster than the Intel even with a faster cpu processing speed.

I am running about 56 threads on the Amd compared to 36 threads on the Intel. I suppose the next reasonable step is to lower the number of the threads on the AMD to match the Intel and see how the horses run.

yup. i pulled the 1060s in favor of a 2070. the 2070 is a little more than 2x as fast as the 1060s, so the RAC probably will only slightly increase.


I had to add a third gtx 1060 3GB to my Intel to make it back to nearly 110,000 RAC now I am wondering just how far up it will go? Based on various theoretical estimates, it seems like it should top out near 150,000 RAC at the very most.

Then I can send the "3rd card" (to the tune of the 3rd Man theme) back to the 2990WX which is going to turn into a 3 gpu box in the near future.

I guess a plan to buy another GTX 1060 per payday is afoot.
I dont think anyone can touch the two top masters but I'm close to the first page so I've done the best I can afford.
I was tinkering with the idea of a mass campaign to recruit crunchers on my account but I'm not sure how to approach that.
I am not the social butterfly that some seem to be...

Alas, we are all who we are at the core...


GROAN... your pun shakes me to the "core."

Is your goal to get to the first page of the LeaderBoard on the individual contributors or to make it on to the first page of the top computer LeaderBoard or both?

If you have a GTX 780 or 780 Ti, there is a CC 3.5 special app for them. But you would be better off power usage wise with a later family model GTX card.


I am running a GTX 750Ti on Linux/CUDA91 here https://setiathome.berkeley.edu/show_host_detail.php?hostid=8565979 and the Gtx 750Ti gpu is ticking along at around 4 minutes per Seti gpu task. That is almost twice as fast as a Windows gtx 1060 3GB running the standard Seti SOG gpu task that I had.

The system is running a heavy mixed BOINC load on the cpu side so the results are less than a pure Seti box would show.

. I'm not familiar with any of the AMD APU chips so have no opinion. Mike would have an opinion on use of that host cpu/gpu combo.


I have a little familiarity with some of the older APU's (I have an A4 and an A6, had an A-10?) and we have been "watching" the newer generation of Ryzen 3 2200G, Ryzen 5 2400G's. From a pure Seti production point of view, the short answer is don't go out and buy any of the APU systems. Or if you do, plan on adding a discrete gpu card like a 750Ti or 1050 or higher in the future. Otherwise it appears you are mired in the sub 5,000 RAC ranks, even the sub-2,000 RAC ranks.

We discuss various ideas for speeding them up here based on the research threads I have been pointed to by other helpful Seti-Citizens (eg. on a 4 cpu system, running 3 cpus gains you more total production when running the gpu than running 4 cpus and no gpu).

But is any of that information hidden? No, it is right there in the download instructions on what is necessary to use the package. Just three Terminal commands and you are ready to double click the Manager to start BOINC.


Must be in some docs I missed. Didn't see them on the directions inside the archive. And you can't get inside the archive unless you have installed the p7zip. And the last page I downloaded the "all in one from" didn't have any download directions about the 3 items I mentioned. So need to mention them frequently for the poor readers like me :)

Post:
What's everyone else's setup? is there a best practice for running CPU and GPU?


Best results depends heavily on exactly what your hardware is, what OS/Apps you are running etc.

If you were running 100% of your cpus at 100% of the cpu time, then reducing it to 90% of your cpus "should" release more resources for the gpu's to use to crunch with as well as providing some "reserve" power that other cpu's can use as needed. Often 80%-85% makes good sense because it increases your total production.

It gets trickier with low core systems. If you had a 4 core system, there have been good results with idling 1 core. Especially in the APU (Amd integrated cpu/gpu) systems.

I have a 8 thread system that is running Windows and a mix of Seti and a bunch of other apps. Even with suspending the gpu when I was on the system, it became a little laggy because I was running so many tasks. So that one got reduced to 75%-80%.

You are running standard Seti under Windows at the moment. So using 1 cpu core to drive 1 gpu task for the SOG tasks makes perfect sense. Once you have a solid baseline of 1 task per video card, you can try 2 tasks per video card. While the absolute speed of your gpu tasks might decrease some, your total production may go up. It is even possible production will go up with 3 tasks video card.

You have to try it out and see. If you weren't running those Titan's I would not be suggesting multiple gpu tasks. For cards less than the gtx 1080/Titan the results are almost always much slower.

I thought you were asking for the TR. It could very well be backwards for Intel. It all depends on how the BIOS writers define memory interlacing. So dependent on motherboard.


I was asking about both. Your response was clearly aimed at the 2990WX (at least clear to me).

In addition to seeing early results on the Intel MB I now have early results with memory interweaving = channel.

I now have 4 tasks that are taking above 4 hours at this moment. Since I haven't seen that level of outlier since I got a MB with a fully working memory system I believe I have empirical support for =channel turning off NUMA.

What is fascinating is it as a setting for "die" (I think this refers to cpu die) which sounds like it would "force" NUMA on cpus with direct local memory. The default is "auto" which means I don't know which it is actually doing :(

I guess I need to re-boot and byte the bullet and see if there is a visible difference between "auto" and "die".

Re-boot. re-boot...

Post:
Which mode of memory runs Seti faster? NUMA (Non-Uniform Memory Access) or UMA (Uniform Memory Access)?

I am asking for two reasons.

My Largest dual Intel has a NUMA toogle which is now on (I think). From what I am reading, games that can run/fit into 1 cpu thread's direct memory will run upto 5% faster.

And I am wondering how/if NUMA/UMA effects the processing speed when half the cpu cores need an extra jump to get to memory (like a 2990WX). I haven't actually found a NUMA/UMA toggle in my Amd MB bios though.

Thank you.

Tom


Some results on turning off NUMA on my dual Intel box are in. Instead of pretty much running 1 hour and 12 minutes the cpu tasks started becoming more like the current results of my 2990WX. Some tasks started taking 2 odd hours. So I rebooted and turned NUMA back on :)

Stephen made a thread showing the simple steps to installing Linux. Then it is very simple to go to Crunchers Anonymous and download TBar's All-In-One BOINC package which is already pre-configured to run the special CUDA9 app. As simple as unpacking the downloaded file onto your desktop and double clicking the Manager executable.


I so stipulate. But you apparently still have to install p7zip, webkit*, and curl* from the command line or I can't get it to work :)

NUMA(UMA) access through the BIOS is in the memory channel interleaving configuration. I can't remember which board you have. Depends on the board where it is the BIOS. For ASUS it is in the NBIO >>Common Options >

Setting the memory access to Channel mode is setting for UMA memory access. Setting for Auto is for NUMA access.


Thank you, I did find the setting. Under the dram stuff but apparently they got it backwards in the google lookup. They said "channel" turned on NUMA :)

Up.

Without manual OCing engaged but all the automatic turboboost (with Cool&Quit off and ram set to speed that is installed [2667]) it is reporting about 3.4GHz. Running 58 odd threads.

So now to see how the estimated task times settle down to.


The gpu times are holding stable in the very low 2 minutes.

The cpu times appear to be ranging from 1hr 15minutes to 2hrs 45minutes.

The turbo boost still seems to be running at 3.3GHz.

My best guess is Q4 2019 for consumer 7nm parts.


So we might get some kind of Threadripper 3 in the 2990WX by then?

I wonder, will the threadripper3 in 7nm cpus need a need a new MB socket or will we have the same direct access to memory issues the 2990WX has now?

I built three of these systems in 1998 and they ran up through until 2007. I ran BOINC, (can't remember what Version now), with Lunatics, (can't remember that Version #, either), and I remember them taking up to 28 Hours on CPU Tasks in 2006.

I also had an AMD K6, 300MHz that died that year in 2006, and I replaced that unit with an Intel Pentium III and a different Motherboard. My "Newest" System back then was an Athlon, (original 1st Generation), 1GHz System on BOINC and Lunatics.

I SWEAR that I remember Lunatics making use of CUDA! But, I'm being told that I'm remembering wrong... So, what App was Lunatics using for SSE Capable CPUs back then?


TL


Now that you are remembering the K6 maybe you should change your tagline to "Come along K6" and see how many people "get it" ;)

The current prediction is my CPU water cooler is due in by "end of the day" tomorrow. So I hope to have the 2990WX back on the air by no later than Wednesday. I hope.

We just picked up an inch of snow and it is still flaking. I normally haul the box to my PC technician for this kind of install. I may have to try to fake it into place myself. The chassis is fairly bulky to be wrestling on this slippery ground.

I did move one gtx 1060 3GB to my Intel. I have another on order along with the recommended ram.

@Kevin,
Have you changed anything? Your wallclock time for cpu tasks is down but the cpu speed is all over the place. Like you stopped OCing and are just using the Turbo Boost options or something else?
