Parallelism delivers the capability High Performance Computing (HPC) requires. The parallelism runs across several layers: super scalar, vector instructions, threading and distributed memory with message passing. OpenMP* is a commonly used threading abstraction, especially in HPC. Many HPC applications are moving to a hybrid shared memory/distributed programming model where both OpenMP* and MPI* are used. This webinar focuses on the OpenMP parallel model, and particularly on profiling the performance of OpenMP-based applications. Intel supplies a powerful performance profiling tool, Intel® VTune™ Amplifier XE, that is quite handy for finding performance bottlenecks in OpenMP codes. In this webinar, we will go through the steps necessary to profile OpenMP applications, and will describe how you can quickly identify performance issues with task granularity, workload imbalance and synchronization using Intel VTune Amplifier XE.
Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
