Title: Post Your Hash/Sec and Hardware Post by: lachesis on June 04, 2010, 06:41:24 PM Hello all! This thread is exactly what the title says: a place to post about the node(s) that you are running, including their performance and hardware.
To find out your performance, you'll need to build from source with laszlo's patch (http://bitcointalk.org/index.php?topic=43.msg1327#msg1327). The performance in hashes / second will be listed in the UI where it used to say "Generating..." and will spam your debug.log. I'm currently running Bitcoin on three machines (and I tested it on a fourth, but that one is for a business, so I can't keep it running). My Workstation Specs: HP HDX 16t - 16" laptop Intel Core 2 Duo P8700 (x64) @ 2.53GHz w/ 3072KB cache 4GiB DDR2 RAM nVidia GeForce GT 130M (OpenCL needs to get its act together!) Ubuntu 10.04 LTS 64-bit (2.6.32-22) Performance: **Perf - thread 3 : 446k iter/sec **Perf - thread 4 : 451k iter/sec **Perf - total : 897k iter/sec (2 threads) My Home Server Specs: 1400MHz Intel Celeron w/ 512KB L2 Cache 512MiB of (ancient) RAM Debian testing 32-bit (not sure the kernel version) Performance: **Perf - total : 169k iter/sec (1 threads) Puny! :D My Xen VPS Specs: Not 100% sure about this, but it's using 4 cores. 256MiB of (fast) RAM Ubuntu 10.04 LTS 64-bit (not sure the kernel version) Performance: **Perf - thread 1 : 436k iter/sec **Perf - thread 2 : 410k iter/sec **Perf - thread 3 : 419k iter/sec **Perf - thread 4 : 429k iter/sec **Perf - total : 1694k iter/sec (4 threads) So, anybody else? Title: Re: Post Your Hash/Sec and Hardware Post by: SmokeTooMuch on June 04, 2010, 06:43:53 PM someone make a windows binary for noobs/lazy people like me ^^
Title: Re: Post Your Hash/Sec and Hardware Post by: laszlo on June 04, 2010, 06:45:53 PM Make sure you guys try compiling with -O2 instead of -O0 (check your makefiles). It improved performance a lot for me.

It improved performance a lot for me. Laszio, I tried that but it failed. I'll see if I can't address the specific error. Line 15 in net.h failed to compile.Quote from: SmokeTooMuch someone make a windows binary for noobs/lazy people like me ^^ I can try if nobody else replies and this doesn't get accepted into mainline. Not sure what the Windows dependencies are or if I can cross-compile. Win64 or 32?Title: Re: Post Your Hash/Sec and Hardware Post by: SmokeTooMuch on June 05, 2010, 01:01:30 AM Win7 64-Bit here.
Title: Re: Post Your Hash/Sec and Hardware Post by: laszlo on June 05, 2010, 03:14:38 AM You should compile for 32 bit windows (mingw).. 64 bit would just make it use more memory but you'll have to build all the dependencies that way too, if it's even possible with wxWidgets and stuff..
Title: Re: Post Your Hash/Sec and Hardware Post by: lachesis on June 06, 2010, 11:05:47 PM I haven't generated a block since 6/3/2010 while running my VPS (up to 2280 khps) 24/7 and my laptop (1200 khps) every night. I'm rather disappointed.
Title: Re: Post Your Hash/Sec and Hardware Post by: laszlo on June 07, 2010, 12:53:45 AM That seems odd.. are you seeing any instances of 'proof-of-work' if you grep debug.log?
Title: Re: Post Your Hash/Sec and Hardware Post by: lachesis on June 07, 2010, 02:19:00 AM That seems odd.. are you seeing any instances of 'proof-of-work' if you grep debug.log? No, I'm not seeing that on either. On my workstation, the debug.log file has for some reason been clipped at the beginning. It's around 4.8 MiB. On my VPS, it's 20MiB and going strong.Title: Re: Post Your Hash/Sec and Hardware Post by: laszlo on June 07, 2010, 03:54:46 AM Athlon FX-55 (socket 939) on linux

A poor connection could prevent you from generating, though I wouldn't think you would be having that issue at the VPS.
Title: Re: Post Your Hash/Sec and Hardware Post by: lachesis on June 07, 2010, 04:24:02 AM I'm on campus internet. It's pretty reliable. It occasionally asks me to reauthenticate with the master server, but that's fairly rare. The VPS is el-cheepo, but it never drops for more than a second or two. Would it help for me to post or link my debug.log?
Title: Re: Post Your Hash/Sec and Hardware Post by: laszlo on June 07, 2010, 04:38:33 AM Can you post it on a web server or something? It sounds pretty large. I could take a look but it's probably hard to find anything among all the spam.
Title: Re: Post Your Hash/Sec and Hardware Post by: lachesis on June 07, 2010, 10:51:20 AM Sure. My computers ran all last night without generating again.

Title: Re: Post Your Hash/Sec and Hardware Post by: ichi on July 12, 2010, 02:11:20 AM Hello, all :) I'm new to Bitcoin. I'm running client on Ubuntu 10.04 x86 VM with two CPUs and 2.5GB memory. The VM's running in Hyper-V on Windows Server 2008 x64, on old Dell SC1435 with Quad-Core AMD Operon 2376 and 8BG memory.
It's been up for two days, has 15 connections, and currently sees 65,564 blocks. This morning, it generated "50", and tells me that they'll mature in 9 more blocks. That seems more-or-less normal, yes? What's odd is that it's running at 300-500 khash/s when otherwise idle, but is using only about 1% host CPU on average, with occasional bursts to 10%-20%. The bursts seem to correlate with disk and network activity, which makes sense. Anyway, I'm curious why I'm not seeing higher khash/s, given that there's plenty of resources available. Could it be because the VM is running without Linux integration services (which I haven't managed to install successfully)? Or could it be because I'm not port forwarding? And FWIW, I can't do that because I'm connecting through OpenVPN. How can I increase resource utilization? Alternatively, I'm sure that Ubuntu would be happy with one CPU and 1GB memory. Would running four such VMs be workable? Thank you. This is fun. Title: Re: Post Your Hash/Sec and Hardware Post by: Xunie on July 12, 2010, 02:16:25 AM Hello, all :) I'm new to Bitcoin.

I suggest you do that. Title: Re: Post Your Hash/Sec and Hardware Post by: ichi on July 12, 2010, 02:27:44 AM Thanks, Xunie. The host isn't secure, for many reasons (MS knows me well, basically). The VM is running encrypted filesystem, and connects via private VPN.
I'm also playing with Ubuntu 10.04 Server on old gaming machine. I just need to figure out command line access, because there's no GUI. Title: Re: Post Your Hash/Sec and Hardware Post by: robcontact on July 12, 2010, 11:18:49 AM With the default build (Linux x86_64)

Why is bitcoin so slow on VMs? Is it intentional, to prevent corporate/government cornering? Or ???It's better to run it directly on the host operating system. I suggest you do that. Why would we want to slow Bitcoin down? No see, Virtual Machines can cause quite some overhead. And Bitcoin can really use all the resources it can get to generate higher. As with any computer program, or even any real world system, everything is based around bottlenecks. The slowest part in a machine determines the actual speed. More on that here: http://en.wikipedia.org/wiki/Bottleneck (http://en.wikipedia.org/wiki/Bottleneck) Title: Re: Post Your Hash/Sec and Hardware Post by: ichi on July 12, 2010, 05:34:37 PM Why would we want to slow Bitcoin down? Wouldn't it suck if NSA (or Google) cornered Bitcoin market?Title: Re: Post Your Hash/Sec and Hardware Post by: ichi on July 12, 2010, 05:41:13 PM What's the VM bottleneck for Bitcoin? Is it CPU virtualization?
Ubuntu on Hyper-V is particularly slow, I admit. Win 7 x64, OTOH, screams. Damn. Title: Re: Post Your Hash/Sec and Hardware Post by: thufir on July 12, 2010, 06:15:10 PM Hyper-v is a microsoft product. That is your answer. It runs windows fine I'm sure, but it is your problem, not VM technology itself.
For example, I run bitcoin under Xen (linux/linux) and get khash/sec numbers that run with any I've seen posted. Theoretically, I wouldn't think VM would affect bitcoin performance (coin mining at least) more than maybe a minute amount. The hashing code has zero system calls that need to be passed outside the virtual host, there is no overhead, especially in any good VM system like Xen that utilizes Thread Local Storage, Etc... (not saying Xen is the best, only that bitcoin should run undetectably less good inside a VM as out; it does for me.) Title: Re: Post Your Hash/Sec and Hardware Post by: thufir on July 12, 2010, 06:21:12 PM I'm sorry. It could very well be that your hyper-v is running linux in full-virtualization mode (full is bad). If you ran the client OS in para-virtualization mode, then it would run near full speed. I am not sure if hyper-v supports that or what. Linux is happy to run in para-virtualization mode, so most VM systems can do that just fine.

It supposedly works for Red Hat and Debian (???) but I've had no joy with Ubuntu.Perhaps I'll set up some Red Hat VMs. There's another project that needs a virtual network of Red Hat VMs. Or perhaps Win XP VMs, if I can dig up enough full-install packages.

Wow, this is the biggest jump I've ever seen. Nearly a 250% increase in speed from the stock version, amazing. Now let's see how stable it is :)Credit to tcatm for the caching part of the SHA context - this offers absolutely brilliant performance. Additionally, the Intel compiler really comes into its own here as its parallelisation abilities give a massive performance boost over Visual Studio. Performance: 4700khash/s on 4 cores, I think that speaks for itself. I've included both the VS and Intel build, but there's really no comparison, the Intel build craps all over VS.

Title: Re: Post Your Hash/Sec and Hardware Post by: wereHamster on July 28, 2010, 03:39:51 PM 1 thread: ~4200 khash/s 2 threads: ~7700 khash/s Suffice it to say that I leverage SSE instructions to calculate four hashes at once, per thread. I tried to implement your idea and my SSE code is almost exactly 4x as fast as the vanilla code (~2000 khash/s with one thread, up from ~500). However, when running two threads I only get ~3000 khash/s. There is room to optimize my code, but still, the improvement is way lower that yours. I don't think pure SSE can be exactly four times as fast as a well optimized C code, mostly because SSE lacks rotate instructions. Did you implement SHA completely in SSE or are you mixing SSE and C?

However, when running two threads I only get ~3000 khash/s. There is room to optimize my code, but still, the improvement is way lower that yours. Actually, I re-examined my changes based on your results and I think I may have messed up the rate calculation. Since it calculates four hashes per loop iteration I multiplied the increment to nHashCounter by four, but in retrospect it's already accounting for that by incrementing the nonce four times as quickly. Ergo, the rate was displayed as 4x higher than actual. For reference, I've generated 300 BTC (six blocks) since I started using the program on the 11th of this month, which works out to about one block out of every 400 (0.25%). Is that about what you're getting? It looks like your version should be a bit faster than mine, which is only to be expected--this was my first attempt at using SSE, or for that matter any kind of SIMD optimization. I should've known it wouldn't be quite so simple. :) I don't think pure SSE can be exactly four times as fast as a well optimized C code, mostly because SSE lacks rotate instructions. Did you implement SHA completely in SSE or are you mixing SSE and C? I implemented the rotates as ((x >> y) | (x << (32-y))), using SSE opcodes for the shifts. It's implemented completely in C, using GCC's vector extensions--no direct assembly code. I did use intrinsics for the shift operations, since the shift operators aren't implemented for vectors. The rest looks much like the original version.

I should've known it wouldn't be quite so simple. :) Oh yeah, I had to review the khash/s code a few times to get it right. At one point it displayed 12000 but I somehow didn't believe it :) I settled for this: in each thread, for each hash that I calculate, increase a counter. Every couple iterations save the khash/s *for this thread* in an array. Then every 30 seconds one thread sums up all the khash/s values and prints the total. I don't think pure SSE can be exactly four times as fast as a well optimized C code, mostly because SSE lacks rotate instructions. Did you implement SHA completely in SSE or are you mixing SSE and C?

I did use intrinsics for the shift operations, since the shift operators aren't implemented for vectors. The rest looks much like the original version. Yep, that's more or less what I did. Except I used intrinsics instead of the gcc vector extension, I think that should be more portable. It was pretty easy, I took an existing implementation as a base and then only had to change some macros. Comparing my SSE version with the base yields a speedup of (only) 2.5x. It's not 4x, mainly because the lack of rotate operations in SSE. Packing and unpacking also cause a small decrease in speed. I also heard that some compilers can generate suboptimal, sometimes even outright wrong, code from intrinsics. I was advised to stay away from them and use pure assembler instead.
