My next motherboard

  1. I find it hard to believe it is not noisy...

  2. Nitro - that looks sweet. I did a quick google search, but didn't turn up any price info.

    Golly, and fill it with dual cores too...

    Fan noise has gone down dramatically. I believe the claim.

    DeepMarket,

    It is amazing. The only thing more exciting than the AMD hypertransport, which is what makes this connect possible amognst several computers, is IBM's Cell processor.

    I also could not find pricing information.

    I have found a new direction in my search for supercomputer like performance from my systems. It is basically described in this thread (although slightly scattered between posts):

    http://www.elitetrader.com/vb/showthread.php?s=&threadid=82244

    As I gain more experience with using GPUs for general computation, I will try to post it to this thread.

    One thing about these GPUs is that the state of the art GPU cards require PCIe X16 slots. The bad part is that the Quad Opteron that started this thread has _no_ PICe X16 slots :( :(

    So over the weekend, I went out and built a single processor computer from parts using a DFI motherboard that has two PICe X16 slots, and I put an ATI Radeon X1950 XTX. This is a research machine for me, but while I am not using it, it is running folding@home:

    My next step is to put in another ATI X1950 card in, but that is a way off until I gain experience programming them.

    Added four 10KRPM Western Digital 150GB RAPTOR SATA drives to the DFI motherboard machine that I built on the post right above this one. Using RAID 0+1.

    This machine is a research machine for both computation on GPUs, and now as a test machine for SATA RAID arrays for the hosting of real-time tickbase datastore. Currently just using flat file to capture real-time tick data, but time-enabling, I hope to test several "database" systems for the performance and expressive power in real-time, of financial time-series acquisition and query. This includes using binary flat file, MySQL, MSFT SQL Server in-memory, Oracle 10G in-memory (TimesTen), SQL Lite + MySQL used together, and HDF5. All of these systems have a download trial, and some are open source.

    I have written a simulator that continuously multicasts prices on my network for hundreds of instruments (ES, NQ equities, etc) at a very high rate - difference in price updates less than 10 milliseconds. That is on the order of 100 messages per second per asset. These should model extremely busy markets. Should be interesting to see which databases keeps up...

    BTW, I found the following software really useful for benchmarking the whole I/O hardware subsystem:

    http://www.iometer.org/

    Highly recommended.

    The 10K RAPTOR drives are blaaazingly fast...

    Sure,

    Although I don't see a trial version?
