    OLPC has lost its way a long time ago --- at their design phase.
    In previous post on related topics, I've made no secret that I'm displeased with Sugar, and the whole design process (it has no real focus initially).

    Now with a friend of mine who actually owns the OLPC, and having my hands on it, it's safe to conclude that Sugar is crap.

    I've seen non-technical and technical types struggle with the GUI. The GUI is pretty slow, despite the boost in the hardware standards, going from IIRC Geode GX 500 (433MHz) to a Geode LX, and doubling the RAM.

    There should've been clear design focus, treat the laptop as what it is (a specialized, embedded-system grade laptop), and design the software around it.

    Instead, the Asus Eee PC with their distro is doing much better as a computing device than the OLPC. Had there been effort in a) designing educational software, and b) screw the "language-less" GUI, and just work on something that's a lot more intuitive, OLPC could've been a success.

    The OLPC has been overbudget (it isn't a $100 laptop, not close), and underwhelming. I see that Negroponte flirting with Windows as more of an effort to extract some utility out of the hardware. Whether he's doing the right thing, or he's betraying the ideals, or whatever, I personally don't really care anymore.

He also cause a Kent State Computing Science PhD (who's more like a n00b who can't type his password right) to demand the "same" setup, burning up weeks of time for 2 out of 4 IT staff, myself included. The other 2 would routinely try to install pirated software on work computers.

We would try to allocate the right software in time, and if there's no reasonable way to do it (i.e. the user can't get the funding), we try to offer alternatives.

    Apparently, in a bioinformatics research facility, most of the staff who do research don't know jack about computers, or how to maintain them. If the users are allowed to manage their own machine, I would spend so much time fixing machines, I would want to jump off the building.

  12. Re:Why did they buy ATI? on Is AMD Dead Yet? · · Score: 1

    So their reasoning was that by embedded a GPU-style core, which tends to do vector/matrix ops very well, you can basically map all the SIMD instructions to the GPU-style core.
    If you modify the GPU-style core so that it can execute x86 style operations, albeit slowly, you could write schedulers that would dump the memory bound ops onto that core. They could also extend the x86_64 ISA to allow for quick matrix op in the GPGPU.

    Mind you ATI was probably not their first pick, but they failed in negotiating with nVidia.

    In regards to gluing the cores together, the reason why Intel's method works well is that most of the application that uses their 2x2 core CPUs aren't well multi-threaded. Once they are, and you schedule 2 threads with high level of memory sharing on separate cores, it would start snooping caches of the other die through the FSB, and that's a very high penalty. Curiously, the K8 architecture with HyperTransport would mitigate performance issues for cross core snooping, had they just glued 2 K8s together on the same package.

    AMD is fundamentally more technologically driven, and Intel is more business driven. A lot of what they're doing is actually prepping themselves for on-going research. e.g. Research has shown that the core-independent clocking in Phenom/Barcelona will allow for finer-grained control in power usage. Schedulers that are power-aware, and has a power-cap (e.g. the CPU cannot exceed a certain Wattage), will be able to squeeze more performance out of core-independent clocking, than chip-wide clocking. That means, suppose that Phenom and C2D performs exactly the same, other than the Phenom can clock the cores independently, then a scheduler with a strict wattage bound would be able to squeeze much more performance out of Phenom than the C2D without exceeding the bound.

    Their purchase of ATi, and probably to embed GPGPU, is somewhat inline with research on heterogeneous systems, where the cores perform differently. A decent scheduler that would assign the right process to the right core can actually squeeze more performance than your typical homogeneous multicore occupying the same area.

    Curiously, Intel is taking a long long time to actually integrate the memory controller, and ditching FSB. They are also taking their sweet time making a "true quad core", and haven't been able to clock the cores independently, even in their Core 2 Duo. Instead, they have been just shrinking and shrinking the transistor side, and leveraging their benefits, using newer techniques to combat transistor leakage due to the shrink. Making true quad cores aren't easy. Making cores that clock independently isn't easy either - the processor would have multiple clock domains, and there are huge synchronization problems to overcome. Making true quad cores with core-independent clocking would be exceptionally hard. For Intel, a giant in semiconductor manufacturing comparing to AMD (AMD is always at least 12 months behind on feature-size shrink), they have yet to produce anything that resembles that.

    Say what you will about the Core 2 Quads, and how they trounce what AMD offers. Energy management will become more and more prominent issue than just pure performance, and Intel can't bank on feature size shrink anymore. They've got the hafnium high-K to help mitigate problems on Penryn, but transistor size and speed will peak soon, and they would have to move to true multicore, and probably heterogeneous multicore. AMD is still not completely out at the server market - HyperTransport does make SMP much easier (and far less contention compared to FSB), and as long as they survive their immediate problems, I don't see the going away soon.

  13. Re:I call BS on Why Linux Doesn't Spread - the Curse of Being Free · · Score: 1

    Drive failure happens, even within warranty period. That's why if you choose your parts, choose those that have a long warranty period, and if someone's important enough, keep a backup somewhere.

    However, I do, in general agree with you on the problems of Linux. It isn't the perception of free. Joe and Jane Blow will get a computer that either comes with an OS, or get their friend's smart-alecky kid to install something. If that smart-alecky kid isn't a Linux proponent, Windows will get slapped on. Even if he is, chances are Windows will be installed because he doesn't want to explain Linux's quirks to tech-illiterate folks.

    Even when you overcome that, they would occasionally stick a Windows-only install CD into the Linux box, and wonder "WTF? Why won't this install". Wine may now be "beta", but is there an easy setup to detect Windows apps and try and run them? Does Wine have good compatibility to the plethora of Windows software out there?

    Reason why machines like eeePC works is that the applications that most people would use it for are included, and they don't expect to install more software (e.g. there isn't a CDROM drive on there). I'm not saying that Linux has to adapt Window's GUI mannerisms - people can adjust to that. But Linux needs to be even more adaptable to Windows. There's a very strong compatibility problem that Linux needs to combat.

    Either that, or people would start offering Linux with a Windows VM installed in it. And simply tell Mr. and Mrs. Blow that if their software doesn't run, start the Windows VM, and if something went wrong, they can roll back to a snapshot of the VM.

  14. Overengineered against the Silverthorn on New VIA x86 CPU Takes Aim At Intel Silverthorne · · Score: 4, Interesting

    The curious thing is that the Isaiah is heading towards OoO, whereas Intel's going to build the first in-order chip since the Pentium in Silverthorn.

    C7 already has a good track-record for small form factor, low power, and providing acceptable performance at that category. IMO with the OoO they're heading more towards the laptop market, and I think they could've done something at least less conventional with the design.

    Imagine that they modified the C7-M in-order execution core to a 4-way, fine grain interleaved multithreading, and have 2 cores. The existing C7-M has a short pipe, so pipeflushes aren't as penalizing. At the clockspeed that they're starting at (2GHz), each thread would have acceptable performance for your typical workload. And as OSes are becoming more thread happy (OSX is definitely one of them), such design would be at least something different than ordinary. It would be like having a cut down Sun Niagara in your laptop.

    The current design would make it work decently well for low end laptop and desktops, but I can't help but think that the core now has a bunch of stuff that they can't exactly turn off - I haven't heard of a CPU that could switch off its OoO and retire queue, and the die size has increased significantly compared to the C7.
