Instead, heavy iron is even more of a niche, which may be eroded.

        HT or a 2nd CPU will get you somewhere between 10 and 20% boost on your software. It does this letting OS operations like disk IO, video, etc, run on the second "CPU".

          You can't get a 100% speed boost with HT.

          HyperThreading presents a virtual CPU - there are the same number of compuational units in the core. The speed advantage from HT is that with threaded code, there is additional silicon to save the state of each thread.

          With the same number of execution units, however, you can't get better then optimal for a single non-HT CPU; once all the execution units are full, that's it, whether it's one thread or two.

          HT is a great boost for a threaded app where it is not CPU bound in general.

          On the other hand, a second CPU carries an aditional set of execution units; that means you can, in theory double the CPU output.

          Neither helps with the memory - cpu bandwidth issues, which can limit performance. Dual CPU can mitigate that with dual memory controllers (see, e.g. Opteron), but that has it's own complications.

          So, HT is a small step between dual CPU, and dual CPU.

          However, even the most optimistic benchmarks from Intel that I have ever seen quote a 30ish% speed increase with HT. I have never, ever, seen anyone claim that HT can give a 100% speed boost - can you reference that claim?

          I quote from
          http://www.intel.com/business/bss/products/hyper th reading/server/index.htm":

          While Hyper-Threading Technology will not provide the level of performance scaling achieved by adding a second processor, benchmark tests show some server applications can experience a 30 percent gain in performance.


      • In general (and unless you force them, by writing the code that way) Windoze apps are not at all shy about holding on to their CPU time to the exclusion of other tasks and threads. As a (Borland) example, if you're doing a bunch of processing in a loop, then you must include the occasional call to Application->ProcessMessages(), or else your button presses etc. won't get any airtime until the loop concludes. Nothing wrong with that - it helps to keep the program state sort of known when you're handling

        SMP (of which HT is one implementation) is not magic. You do not have any more execution units than you had without SMT. The first thread to be scheduled gets to pick what execution units it wants to use. The second thread gets to pick from the left-overs (then the third and fourth threads on each core in this chip get a go in this example, although HT only supports 2 threads). This means that for each core, you have two non-uniform CPUs. Scheduling threads optimally on uniform CPUs is relatively easy.
      • Not true. Any multithreaded app may NOT show a performance improvement on an SMT machine.

        You can have 2 or more threads that want a shared resource (like the cache) that thrash each other leading to a degradation in performance vs. a single threaded processor.

        Other resources are typically shared like front-end bandwidth, execution bandwidth etc...

        The threads can be NON-symmetric. It's SMT (Simultaneous multithreading).

    Sun has never explained or shown what this Throughput computing is all about. More multi-processors. Yeah, so? You need concurrency mechanisms to exploit it. Pthreads by itself isn't going to hack it. They won't scale up. Even if Sun has "parallelized" Solaris, it's in user space where most of the processing is done and where most of the problems will occur.
    • But aren't those the same problems one faces when writing apps for a multiprocessor system? And yet, you are still impressed if you get an 8-way system for the prce of a 4.

      Heck, just to have an 8-way system in the SPACE of a 1-way, is very damn impressive. But of course your apps have to be written to take advantage of them.
    • Sun sells 144-core systems now. Quite a few of them, in fact. Just becuase doom3 doesn't scale to dozens of processors doesn't mean that real world workloads don't. Web serving, transaction processing, mail servers. These things parallelize very well on an SMP.

      The current problem in compuring is that memory speeds are going up far slower than processor speeds, causing huge cache-fill delays. Sun came up with a simple architecture to keep the processors running anyway, and it is compatable with multiprocessing and multithreading:

      1. Run decoder A until cache blocks on a read
      2. Clear ALU and switch to decoder & register file B
      3. Run B until cache blocks on a read...

    What will be interesting is how the software market adjusts to these multi-core processors becoming more widespread and popular (particularly with dual-core Opteron on the way). They're going to have to rethink things a bit with regards per-processor licensing. From what I recall, Oracle (and many others) consider a dual-core processor two separate processors, and charge accordingly. Anyone running one of these chips would then get stung for a 8 (or possibly 32) processor license.

    Perhaps a better solution would be to adopt the approach taken by IDC (which Sun obviously seem quite happy to back) of counting processor sockets, instead of cores [zdnet.com.au].

    Anyone know what other software companies are planning on doing with their per-processor licensing ?

        It can't compete with the 12K in _any_ sense. It has a tiny fraction of the memory capacity, the memory bandwidth, the I/O bandwidth, the cache, the TLB, the floating point performance, etc.

    After upgrading the Sun server on our network to Solaris 10, all of a sudden the Exchange server stopped working, our Primary Domain Controller went tits up, and the W2K DHCP Server went offline. I've gotten six phone calls in the last 10 minutes from people calling to ask why their workstations say "Welcome to Looking Glass" when they log in. ;)
  • That's just 31 more ways the machine can fail... Have you noticed how the reliability of Sun's hardware has really fallen off in the past few years? I have an SS2 from '95 that is still runnnig (a seti@home client) and has not failed a single time from hardware (other than the initial Quantum disk going dead). At work, there is a hardware failure almost every day. Granted, we have a lot of Sun's, but still...

    • But you have to remember, the Sparcstation 2 was pretty special. One of the best workstations produced ... ever.

      Sun may still have good server hardware -- it's been a while since I've had to deal with it -- but as far as workstations are concerned, I don't think they've ever matched what they achieved with the SS2, compared with the contemporary competition.

      And it even looked good.
    • I have to disagree: we have about 200 Sun servers in our R&D lab, and dozens of Blade workstations. All this stuff, including the recently acquired dual Opteron box, is rock solid, no downtime machinery.

      In any case, I think it's unwise to judge the total output quality of a company, based on just your particular experience, with possibly one single computer or application.

    • Sun's current line of workstations are pretty poor compared to the SparcStations of yesteryear. Back in the mid 1990's they were well worth the expense if you wanted a reliable Unix machine on the dekstop. My SS5 is still whirring away as a firewall and webserver at home. however, if I wanted a decent RISC workstation nowadays then I'd go for a Mac and dual boot either Linux or NetBSD on it.

      Sun's servers are still excellent though, and they're my first choice for serious database machines. Alphas were a g

  • That sounds kinda lot. At least, compared to what Intel AMD and IBM have achieved (or are going to). IBM seems to be in a better position than the other two big chipmakers, but nowhere near 8 cores. And These cores are not some simple, transputer-ish processor implementation. They are quite complex 64-bit SPARC cores (but probably with a much shorter pipeline).

    OK, I think this is impressive.

    I think they're particularly looking at things like the C10K problem (http://www.kegel.com/c10k.html).

    The new Solaris 10 networking code reputedly pays a lot of attention to exploiting, and serving threads well, particularly hardware multithreading if it's available.

    If they could squeeze one of these and maybe 8GB+ of RAM into a 1U box or into their blade centre, then I think it'd do quite nicely for serving web.
