  • What processor is javax.xml.transform Using?

    - by Jeremy Witmer
    I've implented a simple webapp that transforms XML based on an XSTL stylesheet. It works fine on all the Windows servers I've deployed it on (to Tomcat), but on all Linux systems, I get a compile error on the XSLT. As best I can tell, it's because Java 1.6 isn't using the same processor behind javax.xml.transform. On the one Linux system, it's org.apache.xalan.xslt, version 2.4. What I can't figure out is how to generically figure out what any given system is using behind javax.xml.transform. Or, if anyone has any hints on what else I might do to figure out the problem, that'd be good, too.

  • Programming for Multi core Processors

    - by Chathuranga Chandrasekara
    As far as I know, the multi-core architecture in a processor does not effect the program. The actual instruction execution is handled in a lower layer. my question is, Given that you have a multicore environment, Can I use any programming practices to utilize the available resources more effectively? How should I change my code to gain more performance in multicore environments?

  • Just to not to be ingnorant.

    - by atch
    Could anyone explain to me why is it that producers of processors claim that their processor can perform so many thousands (or millions) operations per second and yet typical program (Word, VS etc.) on my machine with 4GB, 3500hz starts with no less than 10sek. Have to mention that I've just formatted disk and tick any necessarry boxes to optimize my machine. So if for example outlook starts in 10 sek I wonder how many millions of operations have to be performed to run such program? Thanks

  • ARM Simulator on Windows

    - by Betamoo
    I am studying ARM Processors from a textbook... I thought it will be more useful if I could apply what I learn on an ARM simulator... writing code then watching results and different execution stages would be more fun... I have searched for it, but all I could find was either a freeware on linux or a demo on windows Is there a simulator that allow me to see execution steps and different changes for ARM processor (any version!) that runs on windows?? Thanks

  • Calculators and C#

    - by Alon
    Does those calculators have some type of a processor like a computer? Is it possible to program to them? And finally, is it somehow possible to run the .NET Micro Framework on it? Thank you.

  • How to generate unique serial number of machine in Delphi?

    - by noxwow
    Hi, I have question how to generate unique serial number of machine in Delphi? I tried to do this using the ID the motherboard or processor, but unfortunately it's unfortunately supported. Partition serial numbers, etc. fall off, because it is changing after the formatted. I'm looking for something that doesn't change after the formatted. Has anyone any idea?

  • AMD sort un processeur 6 coeurs moins cher que celui d'Intel, le meilleur est-il le plus performant

    Mise à jour du 27.04.2010 par Katleen AMD sort un processeur 6 coeurs moins cher que celui d'Intel, le meilleur processeur est-il le plus performant ou le moins cher ? AMD a lancé la commercialisation de deux processeurs X6 de la gamme Phenom II. Dotées de six coeurs, ces puces se veulent être moins chères que les modèles équivalents vendus par Intel. Et le rabais est de taille : là où le i7-980XM d'Intel coûte 999 dollars, le Phenom II X6 1090 T (3.2Ghz) s'acquiert pour 295 dollars. Quant au 1055T (2.8Ghz), il est vendu 199$. Ciblant une clientèle de joueurs ou d'utilisateurs recherchant de très bonnes performances pour leur bureau, ces composants sont à ce jour ...

  • AMD : des puces à trois et quatre coeurs pour PC portables et une baisse des prix pour contrer Intel

    Mise à jour du 12/05/10 AMD : des puces à trois et quatre coeurs pour portables Et une baisse des prix pour contrer Intel AMD vient de dévoiler des puces triple-coeurs et quadri-coeurs spécialement destinés au marché des Notebooks. Ces puces Phenom II tourneront à une vitesse allant entre 1.6GHz et 2.3GHz. Elles visent bien évidemment à essayer de contrer la concurrence de plus en plus virulente d'Intel qui devrait, de son coté, lancer une gamme de puces entre ses Atoms (pour Netbooks) et ses Core i5/i3 (pour desktop) spécialement conçues pour ce marché des portables hybrides. Rappelons que les Notebooks ...

  • AMD sort un processeur 12 coeurs, devance-t-il Intel à tous les niveaux ?

    AMD sort un processeur 12 coeurs, devance-t-il Intel à tous les niveaux ? Depuis quelques années, les processeurs les plus répandus sont ceux comprenant deux ou quatre coeurs. D'autres existent, dotés notamment de six coeurs (ou plus), mais ils sont assez chers et plutôt destinés à des usages professionnels dans des serveurs ayant un grand nombre de charges de travail à traiter en parallèle. Plus il y a de coeurs, plus il y a de rapidité, si tant est que les programmes en face puissent tirer tout l'avantage de cette puissance. Généralement, les serveurs utilisant ce type de puces les lient ensemble en un gros cluster. AMD amène donc sur le marché un processeur encore plus puissant, doté de 12 coeurs.

  • Cannot access updated Java object from Saxon XSLT processor

    - by chipk
    I am working with an open source version of the Saxon XSLT processor "Saxon 9.0.0.2J from Saxonica" and am trying to make use of the java extensibility for the first time. I am running into an issue I suspect may be a limitation on the open source version, but wanted to check first whether there might be something I am just missing here. From the snippet below, my result is that the final value of $c1 does not change as a result of the call to greg:setTime() - i.e. the $c1 variable within Saxon appears to be unhooked from the underlying Java object and there is no apparent way to access the object as updated by the setTime() call. NOTE that all code in the snippet is tested and working otherwise - i.e. $c1 is properly instantiated by the getInstance() call, $startdate is of the proper format and $d1 is properly instantiated. Thoughts? <xsl:transform ..... xmlns:sql="java:java.sql.Date" xmlns:greg="java:java.util.GregorianCalendar" ..... > .... <xsl:element name="JobExpireDate"> <xsl:variable name="c1" select="greg:getInstance()" /> <xsl:variable name="d1" select="sql:valueOf($startdate)" /> <xsl:variable name="void" select="greg:setTime($c1,$d1)" /> <xsl:value-of select="$c1" /> </xsl:element>

  • Processor, OS : 32bit, 64 bit

    - by Sandbox
    I am new to programming and come from a non-CS background (no formal degree). I mostly program winforms using C#. I am confused about 32 bit and 64 bit.... I mean, have heard about 32 bit OS, 32 bit processor and based on which a program can have maximum memory. How it affects the speed of a program. There are lot more questions which keep coming to mind. I tried to go through some Computer Organization and Architecture books. But, either I am too dumb to understand what is written in there or the writers assume that the reader has some CS background. Can someone explain me these things in a plain simple English or point me to something which does that. EDIT: I have read things like In 32-bit mode, they can access up to 4GB memory; in 64-bit mode, they can access much much more....I want to know WHY to all such things. BOUNTY: Answers below are really good....esp one by Martin. But, I am looking at a thorough explanation, but in plain simple English.

  • I have a problem with a AE1200 Cisco/Linksys Wireless-N USB adapter having stopped working after I ran the update manager in Ubuntu 12.04

    - by user69670
    Here is the problem, I use a Cisco/Linksys AE1200 wireless network adapter to connect my desktop to a public wifi internet connection. I use ndiswrapper to use the windows driver and it had been working fine for me untill I ran the update manager overnight a few days ago. When I woke up it was asking for the normal computer restart to implement the changes but after rebooting the computer, the wireless adapter did not work, the status light on the adapter did not light up even though ubuntu recognizes it is there and according to ndiswrapper the drivers are loaded and the hardware is present. the grep command is being a bitch for some unknown reason today so this will be long sorry Output from "lspci": 00:00.0 Host bridge: Advanced Micro Devices [AMD] nee ATI Radeon Xpress 200 Host Bridge (rev 01) 00:01.0 PCI bridge: Advanced Micro Devices [AMD] nee ATI RS480 PCI Bridge 00:12.0 SATA controller: Advanced Micro Devices [AMD] nee ATI SB600 Non-Raid-5 SATA 00:13.0 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB (OHCI0) 00:13.1 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB (OHCI1) 00:13.2 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB (OHCI2) 00:13.3 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB (OHCI3) 00:13.4 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB (OHCI4) 00:13.5 USB controller: Advanced Micro Devices [AMD] nee ATI SB600 USB Controller (EHCI) 00:14.0 SMBus: Advanced Micro Devices [AMD] nee ATI SBx00 SMBus Controller (rev 13) 00:14.1 IDE interface: Advanced Micro Devices [AMD] nee ATI SB600 IDE 00:14.3 ISA bridge: Advanced Micro Devices [AMD] nee ATI SB600 PCI to LPC Bridge 00:14.4 PCI bridge: Advanced Micro Devices [AMD] nee ATI SBx00 PCI to PCI Bridge 01:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RC410 [Radeon Xpress 200] 02:02.0 Communication controller: Conexant Systems, Inc.

  • Does immutability entirely eliminate the need for locks in multi-processor programming?

    - by GlenPeterson
    Part 1 Clearly Immutability minimizes the need for locks in multi-processor programming, but does it eliminate that need, or are there instances where immutability alone is not enough? It seems to me that you can only defer processing and encapsulate state so long before most programs have to actually DO something. If a program performs actions on multiple processors, something needs to collect and aggregate the results. All this involves multi-process communication before, after, and possibly during some transformations. The start and end state of the machines are different. Can this always be done with no locks just by throwing out each object and creating a new one instead of changing the original (a crude view of immutability)? What cases still require locking? I'm interested in both the theoretical/academic answer and the practical/real-world answer. I know a lot of functional programmers like to talk about "no side effect" but in the "real world" everything has a side effect. Every processor click takes time and electricity and machine resources away from other processes. So I understand that there may be more than one perspective to answer this question from. If immutability is safe, given certain bounds or assumptions, I want to know what the borders of the "safety zone" are exactly. Some examples of possible boundaries: I/O Exceptions/errors Interfaces with programs written in other languages Interfaces with other machines (physical, virtual, or theoretical) Special thanks to @JimmaHoffa for his comment which started this question! Part 2 Multi-processor programming is often used as an optimization technique - to make some code run faster. When is it faster to use locks vs. immutable objects? Given the limits set out in Amdahl's Law, when can you achieve better over-all performance (with or without the garbage collector taken into account) with immutable objects vs. locking mutable ones? Summary I'm combining these two questions into one to try to get at where the bounding box is for Immutability as a solution to threading problems.

  • How does one calculate voltages for overclocking?

    - by TardisGuy
    So, all I know is voltage and clock have something to do with each other. Unstable if too low voltage Too high voltage, and too much heat. or higher voltage + lower clock may heat less than that voltage at higher clock. The reason why im asking is because if I can learn how the power vs speed works, Then i might be able to project some kind of thermal curve to find out where my perfect overclock might be (without 50 burn-ins) But, as is apparent im sure. I have no idea what im talking about. If anyone can help me learn more about this; throw me a page, a macro, whathaveyou I will bow before your awesomeness and... Mail you a phantom hand written thank you letter. Some clarification Rev 1 What im trying to learn: is how much power a cpu is using with measurements (Core Voltage) vs (Clock speed) - It would answer the question: Would a 1.4v core @ 4.0Ghz use as much power as a 1.4v core @ 3.0Ghz?

  • Why is my new Phenom II 965 BE not significantly faster than my old Athlon 64 X2 4600+?

    - by Software Monkey
    I recently rebuilt my 5 year old computer. I upgraded all core components, in particular from an Athlon 64 X2 4600+ at 2.4 GHz with DDR2 800 to a Phenom II 965 BE (quad core) at 3.6 GHz with DDR3 1333 (actually 1600, but testing consistently detected memory errors at 1600). The motherboard is also much newer and better. The HDD's (x3), DVD writer and card reader are the same. The BIOS memory config is auto-everything except the base timing which I overrode to 1T instead of 2T. The BIOS CPU multiplier is slightly over-clocked to 3.6 GHz from the stock 3.4 GHz. I noticed compiling Java is slower than I expected. As it happens I have some (single-threaded) Java pattern-matching code which is CPU and memory bound and for which I have performance numbers recorded on a number of hardware platforms, including my old system. So I did a test run on the new equipment and was stunned to find that the numbers are only slightly better than my old system, about 25%. The data set it is operating on is a 148,975 character array, which should easily fit in caches, but in any event the new CPU has larger caches all around. The system was, of course, otherwise idle for the test and the test run is a timed 10 seconds to eliminate scheduling anomalies. A long while ago, when I upgraded only memory from DD2 667 to DDR2 800 there was no change in performance of this test, which subjectively supports that the test cycle does not need to (significantly) access main memory, but yes it is creating and garbage collecting a large number of objects in the process of this test (low millions of matches are found for the pattern set). I am about 99.999% certain the code hasn't changed since I last ran it on 2009-03-17 - but I can't easily retest the old hardware, because it is currently in pieces on my work-bench waiting to be built into a new computer for my kids. Note that Windows (XP) reports a CPU speed of 795 MHz unless I have some thing running. With stuff running it seems to jump all over the place each time I use ALT-Pause to display the system properties, everywhere from 795 MHz to 3.4 Ghz. So why might my shiny new hardware under-performing so badly? EDIT: The old memory was Mushkin DDR2 800 with timings set for auto which should have been 5-5-5-12. The new memory is Corsair DDR3 1600, running at 1333 with timings also auto which are 9-9-9-21. In both cases they are a paired set of dual channel DIMMs. I was waiting to ensure my system was stable before tweaking with memory timings.

  • How can I disable Ctrl+Shift+Arrow from causing my screen to flip?

    - by nizzle
    Windows 7 Home Premium, Catalyst Control Center. Without any apparent reason, after booting my PC, I got this little balloon "HD 4600 Drivers updated". I did not install any new cards or drivers or anything. But now, when I try to select an entire word by pressing Ctrl + Shift + ? / ? my screen flips left to right and upside down. Where can I disable this annoying shortcut? OR Any other way of selecting the entire word? There is no option for this in Catalyst Control Center.

  • Photoshop causing other programs not receive ESC key

    - by user46935
    When I run Photoshop CS4 on Windows 7, other running programs don't receive the ESC key (I noticed in PuTTY and Total Commander's Lister). When I close Photoshop, they start receiving the ESC key again. I tried multiple keyboard layouts, no change. Photoshop is an out-of-box install, no settings changed I exported the list of keybindings from Photoshop (ctrl-alt-shift-k) and ESC isn't used in any combination Why is this? Is there any way to disable or bypass this so that I could use other programs normally?
