In this article an OpenMP* based implementation of the Ant Colony Optimization algorithm was analyzed for bottlenecks with Intel® VTune™ Amplifier XE 2016 together with improvements using hybrid MPI-OpenMP and Intel® Threading Building Blocks were introduced to achieve efficient scaling across a four-socket Intel® Xeon® processor E7-8890 v4 processor-based system.
Our building block is the FD compute kernels that are typically used for RTM (reverse time migration) algorithms for seismic imaging. The computations performed by the ISO-3DFD (Isotropic 3-dimensional finite difference) stencils play a major role in accurate imaging of complex subsurface structures in oil and gas surveys and exploration. Here we leverage the ISO-3DFD discussed in  and  and...
大规模动态重建是一项基础性技术，与位置跟踪结合使用可帮助创建高端 VR 和 AR 体验。在英特尔 CPU 和显卡平台上，通过适当的优化和分区，可以实现高分辨率动态重建。避撞和虚拟对象放置是大规模动态重建的两个主要用例
Intel held the Intel® Modern Code Developer Challenge that had about 2,000 students from 130 universities in 19 countries registered to participate in the Challenge. They were provided access to Intel® Xeon Phi™ coprocessors to optimize code used in a CERN openlab brain simulation research project. In this article Daniel Vea Falguera (Modern Code Developer Challenge winner) shares how he...
Monte Carlo 使用统计计算方法解决复杂的科学计算问题。 它创新地使用随机数字模拟一个问题输入结果的不确定性，并通过处理重复的参数抽样获得一个确定的结果和解决一些以其他方式无法解决的问题。 该方法最早起源于上世纪 40 年代末，由参与“曼哈顿”计划的核物理学家们率先提出。 并采用摩纳哥最大的赌城 Monte Carlo 来命名。
Vectorization Advisor is like having a trusted friend look over your code and give you advice based on what he sees. As you’ll see in this article, user feedback on the tool has included, “there are significant speedups produced by following advisor output, I'm already sold on this tool!”
