Title: What speed are your getting CPU mining TENEBRIX? Post by: Splirow on September 30, 2011, 11:13:29 PM Hi,
List your CPU and mining speed for TENEBRIX Intel Core i5-2500s @2.7GHz using 4 threads 1.37-1.41 khash/sec Title: Re: What speed are your getting CPU mining TENEBRIX? Post by: caish5 on October 01, 2011, 12:54:14 AM Both in Linux...
Celeron 420 @ 1.6ghz - 1.08 kh/s Core2Quad 9400 @ 2.66ghz - 2.05 kh/s per core (8.2kh/s) Title: Re: What speed are your getting CPU mining TENEBRIX? Post by: EskimoBob on October 01, 2011, 06:58:59 AM similar numbers and.
last 14 h = 0 coins. Fuck that! :) If you believe it's going to last and price will go up, buy the coin. Less risk and less bullshit involved (an your ROI is better). Actually, what pisses me off are those 7.7 million premined coins aka it takes 3 year for all of us to even get close to this number. Title: Re: What speed are your getting CPU mining TENEBRIX?

Post by: caston on October 01, 2011, 02:24:45 PM Oh that reminds me a lot of auction houses practically throw out old dual and quad xeon and itanium rack mount servers. I remember them being pretty useless because they had DDR1 EECRAM. Might be ok for a project like this though but the power consumption might not be very good. They were heavy as hell. You needed a trolly to move them and they take up a lot of space.
Title: Re: What speed are your getting CPU mining TENEBRIX? Post by: worldinacoin on October 01, 2011, 02:49:18 PM Well I have tons of these servers, but the thought of racking them again and powering them for a few hashes will be a nightmare. Still trying to convert their PCI to PCIe and doing more moderate hashing.
Title: Re: What speed are your getting CPU mining TENEBRIX? Post by: Bobnova on October 01, 2011, 03:14:31 PM CPUs follow the same curve as GPUs.
A server that uses DDR1 will consume at least 2-4 times as much power per hash as a modern one. Anybody who thinks using CPUs removes the benefit of throwing modern hardware at the issue is deluding themselves, really. The ultimate setup for bitcoin is an AMD board and 5870 class cards (6970, 5970, 6990), the ultimate setup for Tenebrix is likely Phenom II X6 CPUs in a board, or 2600Ks. Either way the people with access to more money get more hashes. Hell the price of a one-unit upgrade is even about the same. PhII+cheap mobo+ cheap ram is around $200-240, same as a 5870 was.

Non high end ati cards are completely worthless for mining. Title: Re: What speed are your getting CPU mining TENEBRIX? Post by: Bobnova on October 01, 2011, 04:08:16 PM Average CPU is probably a core2duo, it'll get between 2 and 4kh depending on the model, OS, and overclocking.
Top mining CPU is almost certainly a 990x heavily overclocked, say 4.0-4.4ghz or so. It should weigh in at 16-20kh/s. So yeah, there's a smaller gap, but it's still mighty large. Have fun finding a block with a core2duo :P Title: Re: What speed are your getting CPU mining TENEBRIX? Post by: Lolcust on October 01, 2011, 04:15:39 PM Phenom II costs a fraction of a top GPU and is far more commonly encountered that high-end videocards.
Title: Re: What speed are your getting CPU mining TENEBRIX? Post by: bulanula on October 01, 2011, 05:24:14 PM Don't really know if I am doing this correctly but mining on a 2600K at stock everything gets me around 0.95 for each thread so about 0.95*8 in total 7.6 khashes/s. Anyone else with a 2600K ? Might try to OC.

It's a 4core 3+ghz Phenom II, getting 1.8kh/s per core So are you telling me that your AMD is better than my 2600K at this ? LOL then it seems like Intel is the next Nvidia when it comes to CPU mining ! Anyone with a 2600K wanna try ? Maybe it is just me and I am doing it wrong etc. !? How long to get a block with 7.2 khash/s ? Title: Re: What speed are your getting CPU mining TENEBRIX? Post by: froggy on October 01, 2011, 10:05:41 PM Getting about 1 kh/s per core on my dual core pentium E2220 (2.4Ghz) when nothing else running, and about 0.7kh/s per core when working on the pc with quite a bit of stuff open.
bulanula, at difficulty of 0.041, it should take an average of 6.79 hours ish for your zippy 7.2 kh/s. Title: Re: What speed are your getting CPU mining TENEBRIX? Post by: bz on October 01, 2011, 10:19:52 PM I've got two systems with i7-2600Ks (3.40 GHz). I have 3 GPUs in these systems so am mining TBX with 7 threads (instead of 8). Each thread is getting about 1 khash (7 khash per CPU). I've got two other miners that have only semprons in them. I'm wondering if I should upgrade those systems to use 6 core Phenom IIs...
Title: Re: What speed are your getting CPU mining TENEBRIX? Post by: kjlimo on October 02, 2011, 01:00:10 AM Alright, so I've figured out how to run this thing (I think), but the pool doesn't seem to be getting any blocks and it's been around 4 hours.
All I have is an estimated .133 tenebrix.... doesn't seem worth it. TBX Estimate: 0.13307985 TBX Title: Re: What speed are your getting CPU mining TENEBRIX? Post by: demkd on October 02, 2011, 05:25:14 AM i7-2600K @ 4.4Ghz
HT enabled: 1.19 x 8 threads = 9.52Khs HT disabled: 2.2 x 4 threads = 8.8 Khs Solo mining, one block ~ 5 hours. Title: Re: What speed are your getting CPU mining TENEBRIX? Post by: Bobnova on October 02, 2011, 05:39:47 AM 2600k at 4.2 with linux minerd and HT on, 13kh/s running 7 threads.

Thanks Simplecoin! Title: Re: What speed are your getting CPU mining TENEBRIX? Post by: Winnopeg on October 03, 2011, 06:10:09 AM What I've got access to:
AMD Phenom II X4 955 OC'd to 4GHz, Windows 7 64bit: 1.95 khash/s, three threads (one core left for cgminer) = 5.85 khash/s Intel Core 2 Duo (T5750) at 2.0GHz, Windows Vista 64bit: 0.43 khash/s, two threads = 0.86 khash/s Intel Atom N270 at 1.6GHz, Ubuntu 11.04 with minderd.exe running through WINE: 0.41 khash/s, one thread = 0.41 khash/s With the proper minerd for linux the Atom only seems to get 0.18 khash/s. Not sure if it's a calculation error or what, but the Atom does seem to be able to do 1/2 the work the C2D does. Title: Re: What speed are your getting CPU mining TENEBRIX? Post by: grod on October 03, 2011, 06:19:04 AM 2x i7 920 at 2.8 ghz - 2.1 x 4 = 16.8 khash/sec. Averaging about 10 blocks every 24 hours so far. Not bad -- that's about the same as 2x5830s mining bitcoin. I'll probably shut down once the 30 or so bitcoins at .0014 are claimed though, definitely not worth doing at .0001.

So you are the one unloading TBX as soon as they are mined all day long keeping the price down ?

Post by: tacotime on October 05, 2011, 12:17:00 AM 1.80kh/s per core, 1055t and 940be at 3.8ghz
1055ts are the cpu to buy to mine tenebrix, they are 120$ used and do 3.4 to 3.6 ghz on stock volts (11kh/s). When the 8 cores come out in a week, they should demolish the 2600k in price/performance for tenebrix Also don't be aware cpu overvolting can sometimes double the amount of power used, i wouldn't bother using overvolted processors because you will lose a lot from your power bill.

If so the problem should be resolved as computers move from 32 to 64 then to 128 bit word sizes etc. Yes, exactly, though I'm being told that the problem could be solved even before we move to 128 bit processors, just currently there exists no urgent need for a blockchain with 200+ billion coins in it.

No idea what the wacky results were about, but they seem normal now that I recompiled it. But, yeah, the high performance binary seems to require the gcc4.6.1 libraries. you should get roughly 200% performance though if you compile them correctly. Now I'm getting 34 kh/s on 10 AMD K10.5 cores. I would post binaries but like I said, they don't translate well across variable gcc versions... You are best off compiling your own with gcc4.6.1. Also, by the rate the hash rate seems to be increasing from block speeds I think we're into the hundreds of kh/s. I don't think there'll be a chance to 51% this if the adoption keep rising exponentially like it has been for the last week. Title: Re: What speed are your getting CPU mining TENEBRIX?

Any flags I should pass on for intel? Looks like 4 threads is faster than 6, I suspect the 256kb/core of L2 isn't enough to keep two threads worth hanging around and data gets exiled to L3 land. PhII CPUs of course have 512k/core, and don't try to do the hyperthreading routine. BD and it's 1mb/core should be nice. EDIT: So far looks like -O3 -Wall -msse2 is best.

Post by: Bobnova on October 08, 2011, 03:57:25 AM I've managed to get vaguely close, but not really close enough, their (stupid, IMO) decision to gimp L2 is costing us badly.
It really is rather like nvidia vs ATI. nvidia has focused on floating point performance, in Folding@home and other floating point stuff they stomp ATI. ATI (AMD, whatever) has focused on integer performance. Along comes the integer based Bitcoin, and holy crap does ATI compute like mad. Except in this case AMD spent 6 years doing minor improvements to a core that came out in 2005 (2004? Long ago) and spent the money earned from stomping the crap out of P4s on CEO paychecks. Intel meanwhile dumped money into R&D like mad and made the old P3 into the Core2, then with a nice performance lead they kept pouring money into R&D. AMD meanwhile got left in the dust, axed the dumbshit CEO and started a crash program to get caught up, part of that program was to sacrifice some money in the form of CPU die size to get a little bit of performance, to get a little bit closer to intel. It hurts their profit margins (which are crap, roughly speaking), but the die size spent on "excessive" L2 cache has paid off big time for Scrypt type CPU mining. Go figure. Bulldozer they're cranking the L2 up somewhat as it's on 32nm instead of 45nm and doesn't cost quite as badly, plus more L2 really does help performance, even with a ton of L3 floating around. Anyway, if you're an intel user enable as many optimization flags as your CPU supports and that'll help somewhat, as well higher core speed obviously (and not obviously, as L3 speed = core speed on sandybridge chips). If you're on a 1156 or 1366 (three digit core i 7 model numbers), crank up the "uncore" speed, as that's your L3 and L3 speed is the big bottleneck here. It also has the memory controller in it. Ram speed seems to help a bit too, though not a ton. AMD users: Try turning up the CPU-NB (CPU NorthBridge) speed, that's your L3 cache+memory controller. It may help. EDIT: In theory, -mavx can replace the entire -msseX mess, but in theory -march=native should do this whole lump automatically, and it doesn't.

How can I optimize my crap 2600K !? You folks with AMD Phenom II at 3.6 GHz getting 16 khash/s on only 5 cores Me with Intel 2600K at 4.2 GHz getting 9 khash/s on all 8 threads Fuck Intel ! The 2600K doesn't have 8 real cores. It merely tricks the OS into thinking there are 2 cores for each real core to keep the CPU more efficiently loaded. Internally there are 4 actual cores. HT isn't a performance doubler because the CPU only has 4 physical cores not 8. Some applications perform slightly faster w/ HT. Some perform faster w/ HT off. All out database servers have HT turned off for example because we see higher throughput w/ HT turned off. The more the pipeline can be kept full the less advantage HT provides (eventually reducing performance when pipeline is continually full). Your comparison should be based on 4 cores not 8. The 2600K has 4 cores and will perform as 4 core processor when performance per thread is maxed out. Title: Re: What speed are your getting CPU mining TENEBRIX?

Post by: bulanula on October 10, 2011, 10:17:52 PM AMD + Linux = you don't pay anyone ;) You don't have to pay system admin's. Wow. Spoken like a 14 year old script kiddie with no concept of Total Cost of Ownership. Linux isn't free. Hate to break it to you but the cost of the OS is almost immaterial in the total lifecycle cost of most projects. So moving 140TB production and mission critical database to Linux platform would be free? Buying AMD servers, benchmarking them, and ensuring they can handle system load would be free (don't forget salary time spent doing so)? Converting couple million lines of T-SQL into PL-SQL or equivalent would be free? Putting my entire career on the line to save a couple thousand dollars (pennies in our IT budget) would be free? Firing our 24/7 windows/SQL Server support team, hiring and training Linux & Oracle admins would be free? Any system disruptions, delays, downtimes, and reduced performance on a 24/7 mission critical server would be free? In the real world companies really don't care about cost when it comes to mission critical hardware. Nobody looks to save a nickle if there is a risk to uptime. I sure as hell am not going to suggest a move from a stable known platform to a completely unknown platform just to save a couple grand. We tend to upgrade servers once every 4 years. Say we could save $500 per CPU x 8 CPU = $4000 every 4 years = $1000 annually. Not even 0.1% of IT budget. Ditching SQL Server would save us some coin but Oracle would cost even more. Windows Enterprise + SQL Server Datacenter COMBINED is cheaper than equivelent Oracle license. Moving our mission critical server to MySQL or PostgreSQL? I am not going to be the one pushing for it. Seems like you know your stuff. Well done. I was talking about home PCs though :) Title: Re: What speed are your getting CPU mining TENEBRIX?

Not sure I would be willing to put my career on the line for a $20K+ AMD Server. Yeah, I do agree with you to a large extent. Intel has a much better control of their sales channel than the AMD. Intel is also better at publishing the utilities that allow for testing the CPU without disassembling the heatsinks.But historically Intel also had problems with the resellers of their whitebox server line. (I'm not sure if they are still making the whole servers, for sure they do whitebox motherboards that carry no prominent "Intel" mark.) In summary I'd say that the current version of this maxim would be: "You are much less likely to get fired for buying Intel than for buying AMD." By the way, on our tests IOMMU in 64-bit AMDs provides generally better performance than the comparable Intel technology. However we use custom-written database engines, not the obvious market leading ones. Overall I'm pretty much agnostic in this battle, we support Intel&AMD&others 32&64-bit, Intel Itanium, IBM POWER&z/Arch,Sun/Fujitsu/Oracle SPARC. We still have happy paying customers for Digital Alpha,HP PA/RISC, only the SGI MIPS machines dropped out of support. Title: Re: What speed are your getting CPU mining TENEBRIX?

Title: Re: What speed are your getting CPU mining TENEBRIX? Post by: Zor on October 12, 2011, 02:08:09 AM taco here's a report for you.
First, thanks for the Windoze binaries. The stock app nets me 1.76k (max) hashes per second (per core). Your AMD SSE4 binary nets me 2.04k hashes per second (per core). Tried the Intel SSE3 one for the hell of it, nah it won't run. ;D But hey, it's an improvement for sure. Thanks Taco. AMD Athlon II (3.1GHz @ 3.6GHz) 4GB DDR3 @ 1600MHz (9-9-9-24), CPU to NB 2.4GHz.

You'll be getting a few more mhash/sec than you would running a 32 bit cygwin binary.
Title: Re: What speed are your getting CPU mining TENEBRIX? Post by: panerai on October 15, 2011, 02:50:30 PM how many threads per core are you guys running? I seem to get better hash rates when I go well over in amount of threads versus cores. On a 4 core machine, im running 8 threads, sometimes 16. The per thread hash rate goes down, but added, I get much more than running a single thread. does this make sense?
