Hence, every piece is partitioned into some MPDATA blocks, where subsequent blocks are processed one by one, and each block of size is processed in parallel by the work team. It offers notable performance advantages over traditional processors and supports practically the same traditional parallel programming model. Furthermore, the proposed method of reducing extra computation allows us to accelerate the MPDATA block version up to 4 times, depending on the platform used and size of the grid. Since the Intel Xeon Phi coprocessor runs the Linux operating system, any user can access the coprocessor as a network node and directly run individual applications in the native mode. Rewriting the EULAG code, and replacing conventional HPC systems with heterogeneous clusters using accelerators such as Intel MIC, is a prospective way to improve the efficiency of using this model in practical simulations. When the intermediate results will be held in the cache hierarchy, the memory traffic will be generated only to transfer the required input and output data for each MPDATA time step. Another level of parallelization is SIMDification applied within each task thread.

These values are given for the double precision arithmetic, taking into account the usage of SIMD vectorization. The performance comparison of all the platforms is shown in Figure 7.

The requirement of expanding halo areas is one of the mpdaha difficulties when applying the proposed approach, taking into account data dependencies between MPDATA stages and the heterogeneous nature of MPDATA stencils. Rewriting the Mpdata editor 2 code, and replacing conventional HPC systems with heterogeneous clusters using accelerators such as Intel MIC, is a prospective way to improve the efficiency of using this model in practical simulations.

The work teams execute computations in parallel and edifor of each other, within each time step. Oct 18 It is mainly due to the cost of extra computations and communications, which have impact on the performance degradation.

Such kernels have been investigated by many authors over the years [ 891420 — 24 ]. In order to better utilize features of mpdata editor 2 accelerators, the adaptation of MPDATA computations to the Intel MIC architecture is considered in this work, taking into account the memory-bounded character of the algorithm.

Furthermore, the proposed method of reducing extra computation allows us to accelerate the MPDATA block version up to 4 times, depending on the platform used and size of the grid.

In particular, the autotuning technique [ 14 ] is a promising direction for estimating the best configuration of required mpdata editor 2. This strategy also allows us to reduce the loop overheads and improves the data cache locality.

Since 3D MPDATA algorithm includes so many intermediate computations, one of the primary methods for reducing the memory traffic within each time mpdata editor 2 is to avoid data transfers associated with these computations.

The high-speed bidirectional ring connects together all the cores, caches, memory controllers, and PCIe client logic of Intel Xeon Phi coprocessors.

A summary of key features of tested platforms is shown in Table 1. Several functions may not work. The main assumption for using the temporal blocking method is that no other computations need to be performed between consecutive stencils or stages.

Adaptation of MPDATA Heterogeneous Stencil Computation to Intel Xeon Phi Coprocessor

Stencil computations are widely used in scientific algorithms and simulations [ 8 — 10 ]. Mpdata editor 2 expected, the best performance result is obtained using Intel Xeon Phi P.

Table of Contents Alerts. This assumption has been aggressively used by us in [ 14 ] to improve the efficiency of implementing 2D stencil codes on hybrid CPU-GPU platforms by removing or delaying synchronization between stages.

The memory behavior of stencil codes related to their performance on Xeon Phi was the primary focus of paper [ 27 ], where different types of regular stencils were studied.

According to Figure 6 damong the four tested configurations, the best results are obtained for the configuration containing 10 teams, with 24 threads per each team. Remember me This is not recommended for shared computers. The first-order-accurate advection equation is approximated to the second order in, andthrough defining the advection-diffusion equation. In mpdata editor 2, all the chunks are still expanded by mpdata editor 2 halo areas, but only some portions of these chunks are computed within the current block.

Please re-enable javascript to access full functionality. Because of the intracache communications between tasks, the overall mpdata editor 2 performance depends on a suitable method of pinning the task to available cores. Hence, compressing merging the appropriately edito stages loops into packages of stages leads to the reduction of the main memory traffic for the input data. Since each MPDATA block provides computations for all the stages, some extra calculations are required for each block.
