I. How long does record/replay take?
Record/replay overhead is a function of number of memory accesses and the amount of sharing in the test program.
1. Time for recording/replaying a 'region':

2. Slow-down for whole-program recording.

Deterministic replay debugging is a powerful tool that can help find the cause of difficult hard-to-reproduce multi-threaded bugs. Consider using replay debugging if your application fails sporadically or if the details of the failure change from run to run. Replay debugging makes your failure totally reproducible, allowing you to use multiple debugger sessions to zero in on the root cause of your problem.
The Intel® Parallel Studio XE 2015 Update 2 Cluster Edition for Linux* and Windows* combines all Intel® Parallel Studio XE and Intel® Cluster Tools into a single package. This multi-component software toolkit contains the core libraries and tools to efficiently develop, optimize, run, and distribute parallel applications for clusters with Intel processors. This package is for cluster users who develop on and build for IA-32 and Intel® 64 architectures on Linux* and Windows*, as well as customers running over the Intel® Xeon Phi™ coprocessor on Linux*. It contains:
英特尔® System Studio 是一款全新的嵌入式软件工具套件，其中包括 Intel® Inspector for Systems。 本文将介绍如何在嵌入式平台上运行 Inspector for Systems。
我们将以 Yocto Project* 1.2 版为例。 该平台支持多种英特尔主板支持包 (BSP)，它还支持通过它们提供的仿真器进行开发，从而无需运行物理嵌入式硬件仅可使用。 以下步骤介绍了如何设置应用，然后通过 Yocto Project* 仿真器 (runqemu) 在该应用上运行英特尔® Inspector for Systems 集合。 以下是我们运行集合所采取的步骤：
Intel Advisor 2015 Update 1
- Improved the custom install directory process
- Incorporated new Intel® Cilk™ Plus overheads
Intel Advisor 2015 is a successor product to Intel® Advisor 2013. Intel Advisor provides a set of tools that help you decide where to add parallelism to serial parts of your applications. The key features provided by this new major version since the initial Intel Advisor 2013 release include:
