• Visual C++ Openmp programming issue

  I have recently started writing programs in OpenMP.But according to the tutorials and examples the threads that i create should run parallel and at the same time.My serial as well as parallel code takes same time ,Although each of the 2 threads are free for the half of time. Say if i write a program to print hello world it prints (hello world hello world) instead of (hehelllolow ....).A program to calculate sum of an array and multiplication of an array (using omp sections) in 2 separate threads gives the correct final output but time it takes is same as a serial code executed one after another .Why such a thing (I use Visual Studios 2005 . CPU:Core Duo T2300) Please help I am on a project(Btech-V sem-MNIT,Jaipur) ...Show All

• .NET Development .Net Remoting And ReaderWriterLock

  Hi, I am working on a .Net Remoting program. In side the remoting class, I need to use a ReaderWriterLock object. But it seems that all method calls from remoting client can easily acquire the writer lock on that object regardless the lock has been acquired before. Here is the code sample public class RemotingExampleService : MarshalByRefObject {     private ReaderWriterLock lockObj = new ReaderWriterLock();     public void  LockObject()     {         Console.WriteLine(lockObj.IsWriterLockHeld); //return true except the first call         lockObj.AcquireWriterLock(-1);     } } I used Singleton r ...Show All

• SQL Server SQL Server is waiting for an internal operation to complete

  When saving a database diagram, SQL Server 2005 frequently "hangs" for an indeteminate amount of time and displays the message "Microsoft SQL Server Management Studio is waiting for an internal operation to complete. If you regularly encounter this delay during normal usage, pelase report this problem to Microsoft." For one thing, this is an extremely lame and unhelpful message, as it gives no clue as to specifically *who* to report the problem to (Microsoft is pretty big, after all), and an "internal operation" is sufficiently ambiguous to mean anything. I cannot find any references to this problem, and it happens frequently enough that I'm finding it very difficult to use Management Studio for editing ...Show All

• SQL Server distrib.exe --- Many instances running

  How many instances of distrib.exe should be running Yesterday I created multiple publications in SQL 2005. without counting, it looks like each publication has its own distrib.exe.... it this the way it is supposed to work Each instance it holding 8k of ram (not a problem right now) but I have many more publications to create... Please let me know if this is the way SQL server works now Hi William, I am guessing you were used to different behavior on SQL2000 where only one instance of distrib.exe is used to service multiple publications\subscriptions to the same subscriber database. The new behavior in SQL2005 is actually the result of a change in the default value of the 'independent_agen ...Show All
