I've stumbled across a very interesting side-effect of the optimizer when compiling between -O0 and -O2 (there are some other flags, which I'll get to below). First, my code:
ifort 18 feature request: using F08 atomic subroutines with array components (using an integer array component of a derived type coarray together with atomic_define)
Deep neural networks are capable of amazing levels of representation power resulting in state-of-the-art accuracy in areas such as computer vision, speech recognition, natural language processing,
随着 CPU、GPU、FPGA、协处理器与特定领域的计算引擎的结合，计算平台正变得日益多元化。但是，在单个应用中利用这些异构环境进行编程，仍面临着不小的挑战。本视频提供了关于英特尔® 线程构建模块（英特尔® TBB，一种面向共享内存并行编程的领先 C++ 模板库）异构功能的简介，讨论了即将上市的全新特性，这些特性有助于利用异构系统中不同种类的计算资源。
GETPID() is a function that is part of the IFPORT module.
