processor

How can I determine programmatically whether my machine is an x86, x64 or an IA64? On Windows Systems you can get the environment variable PROCESSOR_ARCHITECTURE. Here is an MSDN article explaining the values that can be returned. PROCESSOR_ARCHITECTURE=AMD64 PROCESSOR_ARCHITECTURE=IA64 PROCESSOR_ARCHITECTURE=x86 VBScript, checking the PROCESSOR_ARCHITECTURE environment variable: Set oShell = CreateObject("WScript.Shell") Set oEnv = oShell.Environment("System") Select Case LCase(oEnv("PROCESSOR_ARCHITECTURE")) Case "x86" ' x86 Case "amd64" ' amd64 Case "ia64" ' ia64 Case Else ' other End

I need to find the Name and speed of the processor on my machine. I'm building an open source help desk suite and finding this really entertaining! Thanks for the help guys! As the others have pointed out, using WMI. Do this by adding a reference to System.Management.dll, then calling the following code: ManagementObjectSearcher mos = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_Processor"); foreach (ManagementObject mo in mos.Get()) { Console.WriteLine(mo["Name"]); } Besides "Name", WMI also exposes other interesting facts about your processor. Take a look at http://msdn

How are bit shifts implemented at the hardware level when the number to shift by is unknown? I can't imagine that there would be a separate circuit for each number you can shift by (that would 64 shift circuits on a 64-bit machine), nor can I imagine that it would be a loop of shifts by one (that would take up to 64 shift cycles on a 64-bit machine). Is it some sort of compromise between the two or is there some clever trick? The circuit is called a " barrel shifter " - it's a load of multiplexers basically. It has a layer per address-bit-of-shift-required, so an 8-bit barrel shifter needs

I want to write my application logs in another file than the one Symfony2 writes its own logs and system logs. I understood that I needed to create a service of my own like this : services: actionslogger: class: Symfony\Bridge\Monolog\Logger arguments: [app] calls: - [pushHandler, [@actionslogger_handler]] actionslogger_handler: class: Monolog\Handler\StreamHandler arguments: [%kernel.logs_dir%/actions_%kernel.environment%.log, 200] That works fine when I use $logger = $this->get('actionslogger'); in my application, so that's ok. But I also want to use a Formatter and a Processor to manage the

Possible Duplicate: CPU Affinity I'm running on Linux and I want to write a C++ program that will set 2 specific processors that my 2 applications that will run in parallel (i.e. setting each process to run on a different core/CPU). I want to use processor affinity tool with C++. Please can anyone help with C++ code. From the command line you can use taskset(1) , or from within your code you can use sched_setaffinity(2) . E.g. #ifdef __linux__ // Linux only #include <sched.h> // sched_setaffinity #endif int main(int argc, char *argv[]) { #ifdef __linux__ int cpuAffinity = argc > 1 ? atoi(argv

So i overclocked my phone to 1.664ghz and I know there are apps that test your phone's CPU performance and stressers but I would like to make my own someway. What is the best way to really make your CPU work? I was thinking just making a for loop do 1 million iterations of doing some time-consuming math...but that did not work becuase my phone did it in a few milliseconds i think...i tried trillions of iterations...the app froze but my task manager did not show the cpu even being used by the app. Usually stress test apps show up as red and say cpu:85% ram: 10mb ...So how can i really make my
