[QUOTE=Old man PrimeNet;118586]Fortunately George was not on vacation and emailed James' complaint to me because I was going to check back here in January after my next two vacations [URL="http://www.cirrusrental.com"]this month[/URL] and next (seriously).[/QUOTE]
There are a lot of vacations going on between you two. Have either of you considered getting fixed online identities, but becoming modern-day nomads?(I think that's the right word)

[QUOTE=James Heinrich;118597]I carefully tried it again, and this time it seemed to correctly drop the unwanted CPU and leave my other two wanted ones, so I guess I was probably doing something dumb the first time... :whistle:[/QUOTE]Hmm, both my computers fell anonymous during the day today, shortly after I dropped the other CPU. Perhaps Scott's fix above has solved it, I'll assume it has unless it happens again.


[i]It must be a grand conspiracy: according to [url=http://v5www.mersenne.org/report_top_500/]the stats[/url], I'm in 5th place, so it's either Scott is trying to catch up to me, or George doesn't want me to overtake him, so they keep changing me to anonymous[/i] :razz:

Just one question: Do I REALLY need the Adobe SVG Viewer to view my stats at the v5 server? This Addon is NOT compatible with firefox... :furious:

[quote=Andi47;118670]Just one question: Do I REALLY need the Adobe SVG Viewer to view my stats at the v5 server? This Addon is NOT compatible with firefox... :furious:[/quote]
There's a version of it that is compatible, but Firefox (at least since 2.0...I think maybe since 1.5) supports SVG natively. It's the [URL]http://v5www.mersenne.org/svgcheck.js[/URL] script (which, BTW, is provided by Adobe...and was probably last edited in 2000) that is bringing up that box, since it doesn't recognize that new versions of Firefox can see SVG images without having Adobe's SVG viewer.
If you let it set the cookie, it will only ask you the first time. You should email Scott at primenet at mersenne dot org and tell him about this. If he's handy with JS and VBS maybe he could edit them himself to not ask on browser versions that already do SVG natively...or just remove them, since most (all?) new versions of major browsers support it.
EDIT: IE7 doesn't support it natively...so maybe they should stay, but maybe be edited to either only include IE, or exclude all new browsers that support SVG. Maybe Scott could get Adobe to update it to fix these things.

[QUOTE=Andi47;118670]Just one question: Do I REALLY need the Adobe SVG Viewer to view my stats at the v5 server?

Go to the [url=http://www.adobe.com/svg/viewer/install/]manual download page[/url] for the plugin, select the correct language/OS (e.g. [url=http://download.adobe.com/pub/adobe/magic/svgviewer/win/3.x/3.03/en/SVGView.exe]Windows[/url]) and install the plugin. Firefox will now happily show SVG images on the v5 site (although by default not the .svgz images from the Adobe plugin test).

Prime95 v25.5 doesn't share the CPU very nicely. They say a picture is worth a thousand words, so here's my 2kB:

[i]edit: hmm, this forum doesn't seem to support image embedding. :ermm:[/i]

I did some examples with VirtualDub, some with work that is single-threaded, so that with an otherwise-idle dual-core CPU VirtualDub would only take 50%; some other more multi-threaded work where VirtualDub would naturally take about 65% of the CPU. Results were:
(A) :no: Single-threaded Vdub work, 2 Prime95 worker threads: Vdub only get 25% CPU (half of what it should)
(B) :tu: Single-threaded Vdub work, Prime95 paused: Vdub gets 50% of CPU, as it should
(C) :tu: Single-threaded Vdub work, 1 Prime95 worker threads: Vdub gets 50% CPU (as it should), Prime95 only uses the other idle 50%
(D) :tu: Multi-threaded Vdub work, Prime95 paused: Vdub uses get ~65% CPU (as it should)
(E) :sad: Multi-threaded Vdub work, 1 Prime95 worker threads: Vdub only gets 50% CPU (10-15% less than it should)
(F) :sad: Multi-threaded Vdub work, 2 Prime95 worker threads: Vdub only gets 50% CPU (10-15% less than it should)
(G) :mellow: Multi-threaded Vdub work [i]with VirtualDub set to "idle" priority[/i], 2 Prime95 worker threads: Vdub only gets 33% CPU (which is probably right, assuming that VirtualDub is running at the same priority as each of the worker threads)

With v24.x I never had to pause it because it interfered with any other task, but with v25.x there are many examples like this where Prime95 asserts itself far too much. Tests are all run with VirtualDub task at "Normal" priority, unless otherwise stated. Priority settings on VirtualDub have no effect on how much CPU Prime95 lets it have in single-threaded work.

Get process explorer from sysinternals.com. Click on prime95 and then the threads tab. What priority are the two worker threads running at?

They're running at BasePriority=1, DynamicPriority=1, I/Opriority=Normal, MemoryPriority=5:
[url]http://jamesheinrich.com/temp/CPUhog1.jpg[/url]
The red/green highlighted threads show up momentarily every few seconds, those are running at Base=8, Dynamic=11, but they show up for only an instant every 5 seconds or so.


Another example: I was compressing some videos today with Windows Media Encoder and it would use ~85% CPU with Prime95 paused, but only 70% with Prime95 running 2 threads.

Off-topic: Are these other non-prime95 programs supposed to take less than 100%, or is there bandwidth saturation occurring? I seem to remember that RAM used to run at about the same frequency as the cpu, but started falling behind. Could it be getting so bad that more and more programs won't be able to utilize the whole cpu?

In the case of a dual-core CPU, fully using one core (a single-threaded application) will show up as 50% CPU usage. On a quad-core CPU, a single-threaded application using 100% of a single core will show 25% overall CPU usage. In my above examples, Windows Media Encoder is sufficiently multi-threaded that it can use all of one core plus 70% of the second one, so you get overall CPU usage of (100% + 70% / 2 cores) = 85% usage on a dual-core CPU.

What more can I do than set the worker threads to run at the lowest possible priority?
