    Hi,

    if I buy this computer I have 2 * 6 cores = 12 cores (with hyperthreading I have 24 core).

     

    http://ark.intel.com/de/products/64594/Intel-Xeon-Processor-E5-2620-(15M-Cache-2_00-GHz-7_20-GTs-Intel-QPI)

     

    HP Z620 Workstation-2x Six Core 2GHz E5-2620-64GB-Quadro 2000 1GB-500GB 10K

    http://www.ebay.de/itm/HP-Z620-Workstation-2x-Six-Core-2GHz-E5-2620-64GB-Quadro-2000-1GB-500GB-10K-/390706256232?pt=Desktop_PCs&hash=item5af7e85968

     

    have someone testet the StrategyQuant with a Xenon Processor ?

     

    Is this compatible ?

    Can I use all 24 hyperthreads?

    Hello Thomas,

     

    yes, StrategyQuant can use all the processor cores.

    Unfortunately, we just found a small bug that causes that it doesn’t use all the available cores effectively, so it works slower than it could.

     

    It will be fixed in the next update, so if you’ll buy this computer now you’ll be able to use it fully with the new release.

    Until it s fixed, it’ll still use all cores, but less effectively.

    Hi Mark,

    yes I have remembert that the task switching is very slow at the moment.

     

    But this is no problem. Morst time I start GB more times on the same computer.

    So I have 95% cpu utilisation.

    Thomas,

     

    There is no doubt that the HP would be a nice machine and I would envie you for having one.

     

    From a pure hardware aspect the addition of a second CPU on the same motherboard only delivers at best about a 40% increase in performance over a single CPU, at least on a Win X machine.  This makes it an outstanding web server having lots of cores at low demand but not the best machine for absolute computational speed.

     

    The lack of performance is due to the administration of all the overhead managing shared resources like disk I/o, memory, video, and human I/O (keyboard & mouse).  From a pure theoretical performance aspect there is much more performance to be gained from running two identical computers with dedicated resources using a KVM (keyboard, video, mouse) switch to select which machine you want to control.

     

    Next, the E5-2620 only scores an 8 in benchmark testings while a comprably priced Intel i7 3970 scores a 12+ on the benchmark tests.  Check out: http://www.cpubenchmark.net/high_end_cpus.html

     

    So yes, it would be a nice machine but I believe that you might be able to find a more powerful setup for less money using two computers.

    Hi dave,

    thank you.

    I think the i7 3970 ist the best solution for me.

    Sorry, just wanted to know how if it’s possible to transport SQ to a new machine without any worries? Does it require a new licence or an update of the existing one?

    Hi,

     

    this is not the right topic, but you can transfer SQ to another machine. Just send us an email, we’ll reset the license and you can use it on another machine.

    Hi Mark,

     

    Is the bug related to using multiple cpu cores effectively fixed? If so, is the fix available in latest version of SQ?

     

    Thanks

    Hello Yogesh,

     

    yes, the bug mentioned above was already fixed.
