I\'m currently cooking up a wrapper container template class for std::vector that automatically creates a multi-resolution pyramid of the elements in its std::vector.
I have some threaded C code that req开发者_StackOverflowuires 64 byte alignment of the processed data structure. How will this alignment interact with prefetch instructions like the gcc __builtin_pref
Suppose that my machine word is 32 bits long, and I have to sort 8-character strings. I\'ve read that if you pack the characters into words, the comparisons will be faster since you use aligned memory
could someone pls explain to me how the row alignment of OpenCV\'s CvMat (or its C++ version cv::Mat) works? For instance, let\'s assume I have a matrix
I recently compiled GotoBLAS2 (MacOSX 10.6) and linked it to my code, leading to all kind of wrong results. I ran everything through valgrind noticing some illegal reads from the GotoBLAS. When lookin
Say we have a concrete class A, and an abstract class B. Consider a concrete C, that inherits from both A and B, and implements B:
I wrote a program on linux(x86,32-bit),everything works fine开发者_如何学Go.But when I try to compile and run the same source code on Solaris (SPARC,64-bit),I got a bus error(SIGBUS).The message from
This question already has an answer here: Why does the x86-64 / AMD64 System V ABI mandate a 16 byte stack alignment?
I\'m working on a 32-bit machine, so I suppose that the memory alignment should be 4 bytes. Say I have this struct:
I know this is a weird question to ask in Java, but is there a way to let Java dynamic memory allocation be aligned with some alignment constraints?
