  1. Re:Bah on Alpha. on Compaq: Alpha is Better Than IA-64 · · Score: 1

    Two things here:

    1) MS stopped support for WinNT/Alpha

    2) When it was supported, DEC had a free (as in beer) product called FX!32 that would *convert* your X86 binaries into Alpha binaries as the program run. The parts it hadn't converted would be emulated. The longer/more times you ran the program, the more of it would be native Alpha code.

    Leave it DEC to code stuff like this.

    ``Insanely idiotic OS''??

    Maybe you'd have a leg to stand on if Linux supported the enterprise features that Digital UNIX does.

    Unfortunately, it doesn't.

    Example: High performance, dynamically resizable, journalling filesystem.

    Does Linux have it? No. I'm familiar with the efforts that exist to address this, I work with one of the authors of a major project for this. He'll admit that ext3/reiserfs doesn't touch ADVFS.

    Example: Advanced high availability clustering solution with a shared filesystem among nodes, cluster aliasing, and context-dependant symlinks for a SINGLE disk image shared amoung up to 8 cluster nodes.

    Does Linux have it? No. Be aware that Beowulf is NOT an HA solution - it's a distributed computing cluster.

    Perhaps you should do some more research before blindly bashing an OS that has features that Linux has yet to dream of.

    As a side note, the Alpha isn't only used for supercomputing. I'm part of a group that runs 3 clusters of AlphaServers for everything from mail, web, and database serving. Only recently did DEC/Compaq enter into the supercomputer arena with the ``SC'' series of Alphaserver.

    Your typical DS/ES/GS series AlphaServer may not be meant for your average joe-blow computer enthusiast, but 14 processors does not constitute a supercomputer. The new ``SC'' series AlphaServer that DEC recently released is a 64-512 Alpha CPU model. THAT is a supercomputer.

    I've been using Linux since 1995, and Digital UNIX since 1996, so I've got a pretty good feeling on the comparisons between them.

    -Jeff

    Moderate this down as flame bait if you like - but I have a feeling that most readers have never used Digital UNIX/Tru64, and don't have enough knowledge of it to form a good opinion.

    To a pirate who can potentially make hundreds of thousands per movie (figure pulled out of my ass), the investment in the digital projection system isn't unheard of. The hardware they use now to duplicate films isn't cheap - nor is the film they use to duplicate it on.

    Pirates could also hire engineers to take a look at the projection system, and reverse engineer it.

    Sure, it's an entirely different scale than cracking your DVD player, but it's still possible. After all, cracking a brand-new movie when it hits the theatres is an entirely different scale than cracking your DVD that has been through the theatres, and off-screen for a few months before it gets to your home system.

    I don't really see how either of your examples are relevant.

    VMWare - Runs windows apps *on* windows using a virtual machine *on* a UNIX-based system. Again - they gain the remote display capability because they're using X.

    VNC - Throws the entire desktop around.

    Personally - This is almost what I'm looking for in a Windows remote administration package.

    What I'd LIKE to have is a single copy of a Windows application running, and be able to have multiple sessions to it. Applications run on the windows "desktop" as usual, but you can hook into them via a remote admin package. I don't want the whole desktop - just the app. The application would never know the difference - almost like carbon copy, but without the entire desktop.

    MySQL may be great for larger databases - but what happens if they're getting written to contstantly?

    As far as I know, MySQL only supports table locking, rather than the row locking of Oracle (and perhaps Postgres). We started using database logging for our Apache server, so that we don't eat so much CPU running analog - Statistics would just be SQL calls to the database.

    We started with MySQL and ended up postponing the project - MySQL just couldn't keep up. The hardware isn't the problem, it was a DS/20 w/ 1 GB of RAM, running Digital UNIX 4.0F.

    Since we have other projects, this one has been on hold for some time, waiting for one of us to port our logger to Oracle.

    Just thought I'd mention my experiences with it. I'm not knocking MySQL - We still use it for a decent number of mostly reader databases, but for intensive writers - no way.

  15. Re:Linux is on 80% of Alphas now on Compaq May Nix Tru64 for Merced · · Score: 2
    Biggest selling doesn't mean best.

    Case in point: Windows is *still* the #1 selling OS, does that make it better?

    The fact of the matter is that Linux *still* isn't mature enough for the Data Center. I know there are support contracts available, and I'm aware that some businesses have been moving to Linux in their Data Centers.

    I won't.

    I'm part of a group that runs the Data Center for a major University. We've got over 20 Alpha Servers, ranging from older AS2000s to DS/20s, and soon - a few ES/40s.

    How many of them run Linux? Zero.

    I like Linux. I've been using it since early 1995. I still run it now on my home PC, and my work PC. However, I won't run it in the Data Center any time soon.

    The simple fact is that Linux still lacks some major features that commercial Unices have had for years. These features are what we want. If they happen to be in a "free" OS - great. But they're not.

    Using OSF/Digital UNIX/Tru64 as an example, Linux still doesn't offer:
    • High Availability, Production-level clustering.
      • Beowulf isn't HA clustering, it's processor clustering, and is absolutely useless in an HA environment
      • TruCluster 5, the newest version of DU Clustering software supports:
      • Cluster Filesystem. The filesytem is available to all cluster members using memory channel (does linux support memory channel?) cache coherency is maintained, and the filesystem appears as local to all members. While this isn't a true shared filesystem a la VMS yet, it's getting there.
      • Cluster Aliasing. The cluster shares an IP address, and members will redirect requests internally. Applications written to be aware of cluster aliasing can run, and be served off, all members in the cluster, simultaneously.
      • Shared bus. This is an older feature, but still one of the coolest. 4 cluster members and an enterprise storage array share a single ultra-wide, differential scsi bus. That's not the cool part. In addition to network connectivity, they also maintain availability by monitoring each other over the SCSI bus.


    A MultiVolume, dynamically resizable, journalling filesystem

    • ADVFS has been shipping with DU since v4 (maybe earlier?) We love it. If we have a database that's getting too big, or if users need more space - we add a disk, and add it to the filesystem. Here's the kicker: The system doesn't come down. The filesystem isn't even unmounted.


    There are more, but for the sake of briefness, these are the most important.

    I know that Linux has journalling filesystems on the way. I'm quite aware of the progress of journalling in ReiserFS - the lead journalling developer has the office next to mine. (btw, the press release wasn't his idea)

    Even with journalling support, Linux still doesn't support the other features we're looking for in a filesytem.

    When Linux can support the features we need, we'll switch. Until then, not a chance.

    The "Maya" product, as a whole, consists of multiple packages. The renderer is only one of them. In order to make a complete development package, the user needs to have "Studio aka.

    The "real" cost of Maya is somewhere in the $40,000 - $50,000 range.

    The A|W offering above only has the renderer, which allows Linux to assist/control a render farm, but doesn't support the animation development environment.

    Using Maya as an example of Linux's multimedia capabilities is premature. Certainly, this can be used as an example of Linux's ability to handle computationally complex tasks, but that ability has been proven already.
