Colfax Research | Configuration and Benchmarks of Peer-to-Peer Communication over Gigabit Ethernet and InfiniBand in a Cluster with Intel Xeon Phi Coprocessors

Colfax Research | Configuration and Benchmarks of Peer-to-Peer Communication over Gigabit Ethernet and InfiniBand in a Cluster with Intel Xeon Phi Coprocessors | EEDSP | Scoop.it

Intel Xeon Phi coprocessors allow symmetric heterogeneous clustering models, in which MPI processes are run fully on coprocessors, as opposed to offload-based clustering. These symmetric models are attractive, because they allow effortless porting of CPU-based applications to clusters with manycore computing accelerators.

Cross-compilation for Intel® Xeon Phi™ Coprocessor with CMake | Intel® Developer Zone

Cross-compilation for Intel® Xeon Phi™ Coprocessor with CMake | Intel® Developer Zone | EEDSP | Scoop.it

CMake is a cross-platform, open-source build system. A special file named “toolchain” is required for cross-compilation, and this file should define all tools (compiler, linker, libraries, etc.) needed for building an application.  To invoke Cmake with the toolchain file, use the following command-line option:

OpenCL*: the advantages of heterogeneous approach | Intel® Developer Zone

OpenCL*: the advantages of heterogeneous approach | Intel® Developer Zone | EEDSP | Scoop.it

Along with the rise of General Purpose computing on Graphics Processing Units (GPGPU), GPUs themselves are evolving rapidly from fixed-function rasterization engines to more general processors. Today, discrete GPUs are typically connected to the CPU via the PCI Express* (PCIe) bus, which significantly limits the data transfer rate between the devices. Explicit boundaries for different memory spaces/hierarchies and high latency synchronization between devices result in quite a coarse-grained level of abstraction. Most OpenCL workloads today target the GPU only, leaving the CPU to do mainly scheduling, file and network I/O, and other “host” types of orchestration. In this approach the costs of PCIe transfers might be prohibitive if tasks are small and not amortized well by execution speed of a GPU.

Case Study: Achieving High Performance on Monte Carlo European Option on Intel® Xeon Phi™ Coprocessors | Intel® Developer Zone | EEDSP | Scoop.it

Monte Carlo uses statistical computing method to solve complex scientific computing problems. It innovatively uses random numbers to simulate the uncertainty of inputs to a problem and makes use of computer to process the repeated sampling of the parameter to solve the problem that otherwise impossible to obtain a deterministic result. This method was originally pioneered by nuclear physicists involved in Manhattan projects in late 40s. It is named after the biggest casino in the principality of Monaco.
