VTable Notes on Multiple Inheritance in GCC C++ Compiler v4.0.1

The Basics: Single Inheritance

As we discussed in class, single inheritance leads to an object layoutwith base class data laid out before derived class data. So if classes A and B are defined as:

// the class and launched from within a class instance's method.

#include <iostream>
#include <cuda.h>
#include <cuda_runtime.h>

#define LEN 10

__global__ void kernel(int *a, int *b, unsigned int N);

GCC compiler optimization for ARM-based systems

2017-03-03 fm4dd

The gcc compiler can optimize code by taking advantage of CPU specific features. Especially for ARM CPU's, this can have impact on application performance. ARM CPU's, even under the same architecture, could be implemented with different versions of floating point units (FPU). Utilizing full FPU potential improves performance of heavier operating systems such as full Linux distributions.

-mcpu, -march: Defining the CPU type and architecture

These flags can both be used to set the CPU type. Setting one or the other is sufficient.
