I dreamed last night that I was reading something (I don't remember what) and it occurred to me (in my dream) that I should come here and post about it.

It's odd what real-life things can enter one's dreams.


Reading your dreams?

Umm, make that 26 ... Duh, look at all pages, Jim . Guess those brain cells leaked out in the heat today.



Nah, it was that two legged horse running showing its true leg count.....

Not only a small "primary cache" ("store at least x days"), but a really small "secondary cache" (the "store x additional days"). Something like 1 +0.01
Further, some projects will send you a very inflated amount of work and over-fill the caches which is not good for cache management within BOINC.


Yup, I finally figured out settings on the World Community Grid website to get that to stop. But I am not sure I ever got the Einstein@Home to cooperate.

I guess that is why I got a "no cpu tasks available" on one my boxes a few minutes ago.

Graphic violence shows all the blood and gore of getting shot, die-ing etc. And seems to dwell on it.

Tasteful violence doesn't dwell on it.

The oldest trick is to lead right up to the incident but don't depict that actual details.... and show limited aftermath.

As a fan of well written Military SF I like the action and enough of the consequences to remember people are die-ing. But I don't like graphic depiction of the violence.

Like the old b&w westerns on TV. The guys got shot and died, but there was no blood or drama.

Another leaked Geekbench4 test of the upcoming Ryzen Threadripper 32-core cpu. Article over at Tom's Hardware.

+1

Sometimes I wish I still had my 2990wx rig. Other times I am glad it is gone. It was very irritating to be reduced to 25-27 threads to get decent wall clock processing time.
The new Threadrippers still look like they will be a better buy for straight ahead fast Seti cpu crunching than the 64 core Rome Epyc(sp?) crunching.

If we are going to debate the morality of how you prepare your food, it should probably spin off into a separate thread.

I am an omnivore like everyone but I have been eating meat substitutes a little more frequently. Found a Veggie Pattie (Hamburger substitute) at First Watch that reminds me enough of a hamburger that I have been eating it.

Now, for the next MONTH at least sit back and watch that computer. Don't change anything, just monitor it and let it run. Doing so will get you a half decent baseline from which to see what effect changes have.


Had neighborhood power outage a couple of days ago. Was down long enough for the RAC's to stumble.

The wallclock time on the cpu tasks I "recognize" are usually a bit to well below `1 hour. Some of the others are not.

The cpu speed watcher than I am using (Thank you Keith) shows the cpus pretty much still pegged at right below 4Ghz.

Just added (15 minutes down) a cpu socket fan so that is a little cooler.

Its doing that "set and forget" that everyone should be striving for.

I would recommend the Noctua 40 X 10 fan. The one in the image I posted. Costs less than your eBay total of parts.

Ordered.


Installed.

Early results show
Before: CPU Socket Temperature: +54.0°C
After (Fan installed): CPU Socket Temperature: +50.0°C

All you have to do is Lower the Use at Most ___ % of the CPUs until you reach the point of Not being Over-committed.
Anything else is a Red Herring. That One setting should be all you need to set. That's what the CUDA Developers decided 12 Years ago, and it holds to this day.
All the other stuff is just confusing people. One Setting is All it takes.


I think all three of you are referring to the setting that controls the # of cpus/threads that Boinc will use. Right?

On this system: https://setiathome.berkeley.edu/show_host_detail.php?hostid=8696615

The RAC is still increasing with great enthusiasm. To the point where it has cracked the top 20 (at least for the moment).

The gpus are set to use 0.5 per core using the Linux/Tbar/petro All-in-One combo.

The "cpu over committed" issue on the time differences continues. I am guessing that the difference between the wallclock time and the cpu time usage is about 1/3 (taking maybe a third again more wall clock time).

As I said before, I am waiting for the RAC climb to peter out.....

Has anyone seen any more details on the release date on the 3950x?

Keep looking and the last announcement I find is sometime in September.

Plus I just saw an article that says the shortage of the 3900x continues.

I am re-reading the "Kris Longknife" series by Mike Shepherd He has written more of it that I don't own (yet).

Strong women characters in Military SF. Realistic physics and engineering. Smart-metal. Preexisting gateways from a "Forerunner" race to take care of the science of interstellar travel.

Lots of intrigue, violence is tasteful rather than graphic.

Tom


"Tasteful violence" is a term I thought I'd never hear. Can any violence really be tasteful?

(I understand what you meant, Tom.)

Posted 23 days ago by Profile Tom M
Post:
So I have finally been able to do a little more research about command lines. First, there have been responses in various threads that I feel are relevant, so I'll link them here:
----edit----

4. My sbs value is 1024. As I posted over in an APU memory post, I was wondering if I should assign more memory to the APU. I am thinking it may be worth changing a setting in bios to assign 4 GB to the GPU and increase sbs to 2048 or possibly higher. Is there anything in the stderr output that would indicate if this sbs value is too low or not? In other words, I am wondering if there is a way to see if I am choking the GPU by not having enough memory, or to tell if I have more memory allocated for the GPU than necessary.

5. As a follow-up to the last question, the Lunatics post mentions that pref_wg_size and pref_wg_num_per_cu would affect performance in tandem with sbs. However, I don't think I have seen anyone mention these switches before. Should these switches be added and if so, any suggestions for the Vega 8?
---edit---


I am going to hazard a guess here. My Amd 2400g gpu is listed as being right next to a gtx 1030 in terms of performance on Gpu-Z's website/database.
This means you are not going to get even close to the performance of say a gtx 750ti out of it.

Your ram is bottle-necked by the fact it is DDR4 ram not video-card ram (I think). At least at one time one of the reasons that video card ram was a lot more expensive is you could read/write "at the same time"? which jumped the performance a lot compared to the standard ram of the day. And may still.

Once you get enough ram in there to allow the app to run without paging parts of the program out to the HD (eg. virtual storage) then I doubt unless you want to run 2 tasks at once, that you need more space.

All that said, Viper has pointed out that we have to bow to experimentation.

Presuming you have enough ram on the MB, there should be no hardware issue with running an APU ram space of 4GB and jumping your -sbs way up there. And then let it set at those settings for a couple of three weeks to try to get rid of our problem(s) with variable data helping us to jump to conclusions that may/maynot be warranted.

I would love to see a "real" Ryzen 3000 apu with the next gen Vega/Navi whatever gpu. But you have to consider the market. APU systems are not aimed at the HEDT. They are really aimed at the bottom of the gamer's market and anyone else who needs a basic office machine.

I like the through reviews that Anandtech has about the Ryzen 5 2200g/2400g apus. https://www.anandtech.com/show/12621/memory-scaling-zen-vega-apu-2200g-2400g-ryzen

While they are not Boinc/Seti specific they do explore the limits of this product.
