• Visual C++ Compiling fftw - what flags should I use for best performance?

  Greetings, I have compiled the fftw fft package from www.fftw.org  using the Visual C++ 2005 Express Edition beta 2 but I can`t seem to find a good choice of flags for optimizing the code. As I run the benchmark code that comes with the package I get slower performance with msvc than if I compile with gcc 3.3.3 under cygwin which seems strange because I usually see the opposite behavior. Has anyone else tried to compile this package with th ...Show All

  I can easily identify a process and it's associated threads, memory usage, private bytes, etc.  What I'd like to do is dump that process to a file ( the whole thing, as it is in memory ).  Or at a minimum be able to view what's in that process.  I'm using C#, and the Process class in System.Diagnostics.  Anyone have suggestions on how to get access to what exactly is in the memory of the process I want to access ...Show All

• SQL Server SQL Server 2000 Service Pack 4

  Hello All, I am thinking of upgrading from SP3a to SP4.  It states on the Microsoft site that "SQL Server 2000 SP4 adds platform support for Microsoft Windows Server 2003 x64" It then adds that SP4 addresses specific issues discovered in SQL server 2000 since its ship date. My question is: Is it worth installing on Windows Server 2003 Enterprise which already has SP3a on it   Will it do anything, as Windows Server 2003 Enterprise is n ...Show All

• SQL Server Annoying behavior in report designer

  I have a report with a complex dataset query that involves a temp table. Anytime I make a change to that query and save or change tabs, I get this message: Could not generate a list of fields for the query. Invalid object name #[temp table name]. (Error 208) Fair enough, but the real nuisance is that every time this happens it erases all of the dataset parameters I have previously set up. I have to redefine them every time.
