@jokerdino Ah, ok. I've spent quite some time in the SO php chat, and besides allowing things to go off topic a bit, they would have binned it rather than deleted it if things got too far out of hand. Of course, it's perfectly valid for there to be differences in the policies.
@somequixotic (or anyone else willing to help) besides the modules running, is there any other conflict between virtualbox and vmware? I want to try using virtualbox instead now, but I don't feel like completely uninstalling vmware
@Jasper well... they both do weird stuff with the networking stack too, creating some kind of bridge device usually
it's really inadvisable to have two virtualization solutions installed on the same box, period... unless one or more of them are entirely userspace and do nothing with the kernel, like pure software qemu
you think you have problems with vmware now, ha ha, try seeing the problems you have with vbox and vmware stuff mixed up on the same machine
We're trying to implement an Assembly Inclusion Rule in JD Edwards EnterpriseOne 9.1, by using a calculated table that returns multiple segments. It seems to work fine when the table has a valid entry for the input segments, but when an invalid input is given, the return segments seem to be blank...
@somequixotic I missed your message and just went ahead and installed it. It seems to work alright so far. It helps that we don't really use the virtual networking much (the reason for the VMs is the lack of good bookkeeping software for linux). Now I'll just hope it doesn't blow up until the next major maintenance and then we'll get it all figured out properly.
@tapped-out: overclocking update: The GPU malfunctioned (but recovered) while I was playing Darksiders. It turns out 720/950 wasn't really stable. I've pulled back the clocks to 710/930.
@tapped-out I guess I will have to lose some of that performance benefit. However, those clocks are pretty high to begin with, and it's definitely better than the stock 550/800. Given the age of this laptop, any performance gain is welcome. :)
After all, it is just a Mobility Radon HD 5650, and not something like a 5870...
This system is about three years old, and it seems to be marginal playing modern games. I haven't started Darksiders II, which is more taxing on the hardware than the original. I suppose it will hold up from the benchmarks I've seen, but it's almost time to upgrade. I'm hoping to squeeze as much performance out of the GPU as I can...
Darksiders is running fairly smoothly, hovering around 40-50 fps, but it does seem to be choppy at times. At least I'm getting a satisfactory experience, even if isn't optimal.
@tapped-out How old is your system?
NFS Hot Pursuit seems to be worse in complex scenes, occasionally getting as low as 15 fps, but the overclocking has mitigated this somewhat.
For reference, I'm running an HP Pavilion dv6z-3000 with 2.0 GHz quad-core AMD processor.
The monitor is an average 1366x768, and the game is running at 1360x768 (the highest supported by Darksiders, losing a few vertical pixels).
Darksiders: store.steampowered.com/app/50620 - got it and Darksiders II while it was on sale this past weekend - spent less than $25 on more than $110 of content, including all DLC packs for Darksiders II.
Had it been 1080p, there's no way the 5650 is getting anywhere near 30 fps. Darksiders II gets only 21.1 fps at "1920x1080 2/4 Shadows, No Ambient Occlusion, AF Low AA".
I am finding that the "new" wizz bang faster desktop gpu cards, none of them have magic clock speeds that are way over , even my old GPU. but the ammount of "Shaders" or processing units things, is what really seems to get the speed going.
they can't increase the clock rate or add more ROPs or more VRAM, etc. to make textures sharper and sharper and sharper (the perceptual benefit would be minimal after a certain amount, anyway), but they can build more shader cores and divide the screen into even more tiles (squares) for processing shaders, SSAO, etc
same issue on CPUs. clock rate has hit a physics wall due to thermal dissipation and power requirements
@somequixotic does that mean excessive texture/video memory (when buying a new desktop gpu) is not going to be as nessisary till something changes big in another area?
That's going to give similar pretty performance. Too bad memory bandwidth is so limited on the Mobility Radeon HD 5650: 1 GB of dedicated DDR2 (!) memory.
so it also depends on whether you're running "fullscreen maximized" (window is composited by DWM) or "pure fullscreen" (framebuffer is resized to just the window the game is on, the other monitors go black)
they could fit higher res textures in VRAM, sure, but they wouldn't be able to transform / manipulate / shade them fast enough to give you 60 FPS, that is why texture quality hasn't continued to explode exponentially
it's more of a processing limitation than a framebuffer capacity problem
with a GPU you have to think of things like shaders as essentially parallelizable, and things like higher resolution / higher FPS as essentially requiring a higher clock rate... clock rate isn't going to get much better, ever, until we break out of the digital silicon based integrated circuit paradigm of computing
that is, "serial" performance is stuck in a rut, but "parallelizable" performance can continue to scale pretty much unhindered provided that you have enough fans and your PSU has enough watts to take care of the added cores
some parts of graphics processing are serial and some parts are parallel; GPUs are designed to do mostly the parallel parts well, and each generation does them a bit better than the last, but the serial parts won't improve any more
@DragonLord the increased process size of GPUs is due to their increased heat dissipation -- there are more transistors on a GPU and the die size is often larger, and the TDP higher, so if you take the same amount of transistors and shrink them, you're going to get even more quantum tunneling and voltage leakage and a lower thermal ceiling... and then if you try to add even more transistors the whole thing gets even harder
@DragonLord size has not change the clock rates so much, as just requiring less power to make the same switching occur. so i have not seen where smaller is faster, it is just less power to do the same switching?
GPUs will pretty much always be a ways behind CPUs in process size because the R&D needed to make GPUs smaller is a lot harder than the R&D to make CPUs smaller
@DragonLord not sure about AMD's CPUs, but at least their GPUs are built by Taiwan Semiconductor Manufacturing Corp (TSMC), which is the same company that builds all Nvidia GPUs, as well as Qualcomm's Snapdragon SoCs for smartphones and tablets, which are one of the major ARM mobile GPU+CPU cores
@DragonLord and if they are cramming 1.9V in, they are just selling you overclocked stuff without having to overclock. overclocked and overvoltaged, while that works i dont define it as a real speed increase :-)
TSMC is known for its high volume output, its custom fab software, its low yields in the early stages of production of a new fab node, and being about half a step behind Intel's smallest available fab
but they still make the three best GPU brands in the world at TSMC -- the two fastest, AMD and Nvidia, and the lowest power, the Qualcomm Adreno (based on technology they bought from ATI years ago)
@Psycogeek Smaller is faster because less power per performance means they can get more performance from a given amount of power. IIRC PCI-E specifications dictate a maximum power draw of 300W if a company wants to get a card certified
So being able to consume less power means the manufacturer can do more with 300W
That only really applies to the high-end cards though.
@DarthAndroid and the smaller you get, the less true that is... because of quantum tunneling and voltage leakage and heat
what we're starting to see is that each successive die shrink provides less of an improvement overall than the last generation, because they are fighting all kinds of constraints at those sizes that they didn't have to fight before
@DarthAndroid The AMD Radeon HD 6990 had an Unlocking Switch which would bump clock rates considerably and increase the TDP from 300W to 375W, while enabling access to an unlocked, flashable VBIOS.
@DragonLord the HD7970 is unlocked by default, and it has dual VBIOS support; the first VBIOS is read-only and hard-wired onto the board so it can never be flashed (prevents bricking), but the second one can be overwritten by the user to flash a custom VBIOS, then you have to flip a hardware switch to use the user BIOS
it's neat -- if you accidentally flash a bad VBIOS you just flip a switch and the card is un-bricked
@DarthAndroid not sure about lower end, but the high end ones (always?) have
there might be some hardware limit on how far you can adjust them, but you can definitely use AMD's official Catalyst Control Center software itself to adjust the clock rate on a HD7970 without doing any kind of hacking
i run a completely stock system with stock clock speeds; I have "above average" air cooling in the case though so the ambient temp inside the case is really good, so the GPU doesn't get very hot even under heavy load at stock speeds
i feel that stock speeds make the system last longer, and I have no interest in laying down money for a new system any time soon, so i need it to last a long time
my next upgrade will probably be to Haswell-E, due out maybe in 2015 if we're lucky, and the next major iteration of Nvidia (yes, I've decided I'm switching away from AMD with my next purchase) after the GTX TITAN
@somequixotic way back in time, GPUs had massive leeway for overclocking by the user. a person could say that the parts were highly overrated for the job, and therefore impervious to error and fail. Now things come Pushed to the limit, and there is less space left for increases. Pushed by the people applying the chips
@somequixotic Depends on your hardware. My Sandybridge is OC'd more than 30% of its base speed and has been for some time. It's no trivial amount of boost that you can get sometimes
conservative binning = ship a card with factory clocks significantly below the red line (the area where the card might start to fail or display artifacts)
aggressive binning = ship a card close to or right on the red line, and only bin it down to a lower card if it's significantly more unstable than the mean
the only conservatively binned chips these days are server/enterprise/workstation parts... they intentionally clock them down (and raise the price :)) because businesses want things that Just Work (TM) for years with minimal risk
is it irony? I don't know if it qualifies under that extremely hard to understand concept (irony :)) but AMD's unlocked consumer cards are aggressively binned to drive up stock benchmark scores, while Intel's CPUs are conservatively binned to reduce support requests and warranty claims, and locked to prevent people screwing with them
@BGM what would you estimate the value of the system currently to be? how much is it worth?
you should do a cost/benefit analysis to determine whether it's more economical to buy a whole new system (with all newer parts), or upgrade the existing one and make it a little bit faster for a little while longer
well the problem is, without upgrading your motherboard (and then probably your PSU and RAM) you wouldn't be able to go beyond the Core 2 series of CPUs
word docs, multitasking, checking email, having a bunch of tabs open in your browser, ... this is stuff that could run on a 15 W ARM processor just fine with 8 gigs of RAM and an SSD
i think their new JS engine also compiles the JS down to native (JIT compilation) on page load, which uses a lot more CPU on page load unless the JS is already cached in the native cache
@BGM well if you've got the money to blow, no one's stopping you; but just don't be surprised if there's no noticeable performance improvement when you aren't swapping out the HDD, and you're still using DDR2, and you're still using the same GPU, etc
@BGM people upgrading often have more problems with ram changes than cpu(of the same type) changes, because of so completly different ram modules. A manufactured computer system, could have a POS power supply in there. As power supplys age the capacitors age, and it could be a concideration.
@BGM obviously you would see higher micro-benchmark scores with a new CPU, but as I already said, most workloads that casual users take on are not bottlenecked by the CPU -- meaning, the CPU is more than fast enough for the workload
@BGM He's just commenting on the fact that the vast majority of what an average user does on a computer is not taxing of the CPU, and the CPU is not the cause of most of the wait time that a user experiences.
imagine a trip you're planning, where, you get on a bus that picks you up at your street corner, then drives 10 minutes to take you to a train station where you have to wait 8 hours for the train to get where you're going
I just don't think the CPU will affect anything unless they are doing scientific computing, or gigantic calculations in MS Excel that take more than 30 seconds to run
I remember a recent article from something like TomsHardware or Anandtech that showed that installing a Solid State Disk in an old computer is the #1 way to revitalize an old box
if you can deal with the reduced capacity and cost of an SSD, I'm pretty sure your Core 2 box would feel like a modern Core i7 box (to the secretary) with an SSD replacing the hard drive
they look just like hard drives, mostly, except that they are very expensive in terms of cost per gigabyte of storage, and they are a huge factor in responsiveness of the OS
@DarthAndroid Uh, actually, I am moving her from an Optiplex to the Precision so that she has a working machine whilst I provision the new one. The optiplex has more CPU, but only 2gb of RAM. The Precision will have 4gb of ram.
your next upgrade for the secretary, once you have enough money pooled for it, could be something like a low-end Core i3 Haswell CPU (modern architecture, low latency, low power, etc), 8 GB of RAM, and a small but fast SSD, maybe 120 GB... that system would be excellent for her; she'd love it, and it wouldn't be overly costly
@BGM well.. the networked storage server would definitely alleviate any storage capacity concerns about an SSD, so you could just buy a bottom basement cheap SSD at a low capacity; low capacity SSDs are extremely cheap, and very fast too
the performance wouldn't even be needed if your network is slow, too, btw :-) so either you'd have to already have pre-installed a great network, or upgrade that too
Two things I've been considering: the Synology Disk Station (I don't know anything about it, but it was recommended to me: legionhardware.com/articles_pages/…
personally I would use a bare Linux installation like Fedora or something and customize it from the ground up, but if you're not a Linux head, FreeNAS is help for the helpless in that regard ;-)
I don't do hand-holding through Linux for new users anymore unless either (a) they're a coworker and I'm being paid to help them, (b) they're family, or (c) they are paying for my services, because I get really frustrated trying to guess what's on the user's screen, and I could type it 1000x faster than telling them what to do :p so in that respect, unless you can find someone to hand-hold you through a bare install, I'd say, go with FreeNAS
Personally, I'd rather stick with Windows because I know it. I don't mind, however, muddling through Linux a bit; I already do that with my Asterisk installation.
FreeNAS is a really good project/product though because it's very stable and has all the features you could want in a web interface so you don't have to dig around on the console unless you really hose it up
@BGM FreeNAS is a special purpose operating system based on BSD, which means you just burn a FreeNAS CD/DVD, walk through the installer, and you're done, then you give the server an IP address and you go to the web interface and use it
so you would want to run it on a reasonably capable desktop computer with good RAM and approximately 4 hard drives (more if you want to significantly over-engineer it)
gigabit ethernet would be the ideal way to network it with your router or other networking equipment
though an SSD would last longer because the NAS's operating system hard drive doesn't do any significant amount of writes, and an SSD that never does writes is essentially immortal
whereas an HDD that only does reads will eventually wear itself out
I had to delete "s (some stuff) e (some stuff) x (some stuff) y" from that post above ^ because I was so excited to hear ZFS is supported by FreeNAS that I typed a lewd word lol
