Message 1792448 - Posted: 1 Jun 2016, 3:54:19 UTC - in response to Message 1792442.  

Yep, I clicked on Update just for giggles because I just got home (as it said it was a couple hours before it would auto attempt again), that was at 10:31, and shocker, it was up! Just before that, I had refreshed my screen for the threads here and my system stats page, and it still said system down for maint, so imagine the suprise less than 30 seconds later it had started downloading 100 tasks! I was quite happy as you'd expect.

I figured it out by going into my event log, and looking at the time the last comm was, and then the time of the last task completing. So the 4-5 hour estimate given earlier was pretty accuate, it depends of course on where the 1st half of the cache is in the processing, if most of them have just started it might go a little longer, if most have been crunching for a bit it will be shorter, but this is a decent average for how long it will take to run out of CPU tasks. Not complaining, just noting it is all. :-)

Thanks! My RAC in the software shows that it has rocketed from 0 to 4600 in those 2 short days. Who knows how high it just might go? :-)


Don't know for sure, but can do some ballparking.

IIRC 8 Xeon cores doing MB, back in cobblestone scale days, used to get about 20K RAC on PreAVX AKv8 code. Since then there's been two main credit drops amounting to x ~30%. You claw back a little for increased throughput with AVX (about 1.5x), so my guess with 48 CPU cores alone (AVX capable + fast memory), would be 20K*6*0.3*1.5 ~= 50K (1 significant digit). Lots of variability, especially if adding AP and weird work mixes and GPUs into the picture.

Thanks for the guesstimate, 50k before any GPU input is pretty good I'd have to say! I chatted with EVGA yesterday about water cooling parts for a couple cards I am planning on putting into a system of mine, and found that the new 1080 I ordered almost certainly won't ship this week, and possibly won't even ship next week, but I am crossing my fingers.

I've thought about that from time to time, but I've been a pretty loyal and true blue SETI dude, going back 17 years, so I think I'll probably begin and end my crunching 'career' with them, so, good or bad, I'll take what they give me. Besides, this doesn't really draw _that_ much power when it is idled down not doing anything while waiting. Still need to figure out that site for storing my pics, prefer something that is non-Google, there's photobucket, flickr, and a few others, anyone had good experiences over the longer term with any in particular?

I found lightshot's printscreen utility pretty nifty in the past, a fair bit less cumbersome than negotiating photobucket's links and using the Windows snipping tool.

I use 50webs.net for my web server and like it. They also have a free web server (I tied and didn't mind it)

File transfers are quite easy, and easy to link to.

They also good at the storage side as well? And not gathering all sorts of metrics and data on users? Jeeze, since Snowden, I've just seemed to think about all that business a lot more, both on the govt side and on the corporate side. Everyone seems to want info/data, or monitoring, or both. If this was the 90's they'd say to put on a tinfoil hat and all that, but look where we are today.

And the above statement reflects just what we know, who knows whats going on that we don't? Well, one big solar flare later, like what fried a number of telegraphs around the world on September 1, 1859 and all this tracking and monitoring will be the least of our worries. ;-)

Meh, no idea how much (if any) snooping/datamining may or may not be in the lightshot tray app. Naturally anything supposedly 'free' then you're the product. I only activate the application on the rare occasions that I need it, mostly since I don't like a lot of background applications running anyway. Probably anything/anyone building a digital profile of me would be pretty confused at this point, so I'm less paranoid than I once was.

I've been using Flickr since their startup and have good experience with them. They've changed the interface multiple times over the years but are still very easy to use. Uploads and links to the files are quick and easy. I've primarily used them for my photography but have been using it a lot more recently for images I need to insert in forum replies

Thanks Keith, I thought I would start with Imgur, I was trying to avoid the big boys, and Yahoo owns Flickr. I tried posting a pic in my thread about my unusual "GTX770", and it came thru fine, so it appears that at least it works. If it gives me any guff, I'll switch in a heartbeat, as there are a number of options I've found.

I have accounts with several of the image hosting sites, but I like Imgur. It is currently one of the least convoluted with the features I want.

Here's a few pics of this setup. Fairly basic, but seems to work pretty well so far.






here is a couple pics of my setup that I rigged up to allow 4 or more video cards on one motherboard. Currently it's holding 4, should easily handle 6. Works pretty well for a version 1.0 lol




Lastly, pictured are the results of all my work on my farm team, though I've actually recruited another 8-10 for the team since this one was taken, and my daughter is quite excited that her room isn't a staging area any longer! Now it's just a matter of filling each of those PCI-E slots with a decent quality video card, and I'll be good to go. All it takes is money... Maybe I'll start a GoFundMe! Yeah, that'll work. I'm sure of it.

Well, this is my newest addition,

Just under a week, plus the loss of about 18 hours due to Seti server issues and it's already got 171,000 in credit.
Not bad at all.

Ya ya ya. Hey! I _did_ say it was a 1.0 version of the product, right? ;-) I already have a few different ideas for the supporting the cards properly without having to use squeezeclamps and whatnot. I have the materials, the plans just need a little massaging. But, when you have multicard droop going on, you go for what you know, and I enjoy woodworking, so that made sense at the time. 2.0 will be much nicer, once I get the some of the other projects I have going on around here taken care of, that is a few down on the list.

Nope, no actual issues, I shut it down to perform a video upgrade. It has the 980 in it, and had 2 670s in it as well, all air cooled (for whatever reason, BOINC can't seem to identify more than one video card correctly. I _wish_ I had 3 GTX980ti's! lol). I have had a complete water cooling setup sitting around on the shelf in boxes for about 4 years, for the day I had planed on setting up a killer water cooled system. Well, it kind of fell down the priority list, till it pretty much fell off.

I was looking around at the spare parts pile and remembered that I had a couple of fairly decent cards, both EVGA, a GTX680 and a GTX770 Classified. The 770 is actually quite a bit bigger than the 680, which suprised me, as I thought being newer (7 series vs 6 series) and 'slower' (80 vs 70) the 770 would be more efficient and would actually be smaller, but turns out not to be the case. If fact, I think the 770 actually takes two 8 pin power connectors, I think the 680 takes two 6 pins, not sure what to make of that fact.

Well, since I am already running that system with a Corsair H100 CPU water cooler, I though I would direct all my efforts towards the video end, and install those 2 water cooled cards, and put my kit to good use. In the last couple days, I've gotten the cards plumbed in, and my radiator back from the radiator repair shop. For my radiator, being the overkill/tinkerer guy that I am, I purchased a heater core for I believe a late 70's/early 80s Chrysler panel van similiar to what food trucks use, it was the biggest one that NAPA had, and I got the last one they could find, had to have it shipped in actually.

Well, looking at it, it def was the last one around, one of the inlets was bent a bit, the mounting bracket had broken partially loose, and looked like it was made in the 80s, though I know it was newer than that. I initially took it to the radiator shop to get one side of the mounting bracket that was loose resoldered back on, the 2 fittings attached, and to have it ultrasonically cleaned, because you really don't care all that much if a little crap comes out of it inside an engine cooling system, the tolerances aren't that tight. But, on a CPU water cooled system pump, not so much. They took it in on Thurs afternoon, and had it back to me by yesterday afternoon. Well, turns out the bent inlet actually leaked, so they removed, straightened and reattached it, soldered on the barbed fittings, then fixed it all up and cleaned, flushed it, and pressure tested it to 25 psi, which is much higher than anything it would ever see in operation on my computer.

With that out of the way, now all I have to do is make up an enclosure for it, mount 4 fans to the enclosure, and hook it up to the computer. I hope to have it back up and crunching next week sometime, I miss it's RAC, though not it's power draw. ;-) Installing the water cooling inside the case was 'interesting', as the cards hit the connectors on the bottom slot, and I wanted to use that one to put space between the air cooled one which was mounted closest to the CPU, and the 2 water cooled ones, as when I had all 3 cards in there previously, I know they didn't breath as well as they could have, and thus ran hotter than needed.

Unfortunately, the way that ASUS designed that board and connectors, I couldn't use either of the water cooled cards in the bottom slot, turns out that I had to put the 980 into that slot, and am debating about keeping the USB3 front panel cable plugged in or not, as it is kinda bent clearing the card. It fits, but it isn't right. Who designs these things, anyways? Sheesh. lol

I mounted the 2 water cooled cards into the top 2 slots, and I presume they are all running x16, at least I would hope so, I'll have to check once I get it up and running, but regardless, it'll work fine I'm sure. The tubing wasn't too bad, all things considered, took me about an hour to route it all and get it connected properly. Now that the radiator is back, the rest of the assembly should go pretty smoothly (crossing fingers, don't want to jinx myself), the biggest concern of course is leaks, but I'll deal with them if any pop up. So, that is the saga of my Zoom-PC, hope it will be up and Zooming again soon!

Here are a couple pics I took of the video cards when they were temporarily installed for a quick mock up, and radiator. See the difference in the size of the cards? The 770 is over an inch taller and longer than the 680. So of course they weren't even close to lining up, hence having to do a big loop between them when I installed them.




And that radiator cleaned up pretty good. It was in the sink after rinsing it out a couple more times, as well as filling it up to measure how much it held, about 16-18oz. Needed to know that to be able to verify I have enough coolant on hand, looks like I do. Yay!

A big loop?
I'd have thought the ideal way to use a single pump & radiator on 2 or more video cards would be to use Y or T pieces to split the inlet between the cards then re-join the outlets.
Having the output of one card running in to the input of another card means it won't be cooled nearly as well as the first card.
