The DPC latency checker measures how much time is processing DPCs from driver invocation — the lower the value will result in better audio transfer at smaller buffer sizes.

Results are measured in microseconds and taken as the peak latency while cycling through Gigabyte GA-7TESM1 Matrox Graphics series of short HD videos — under microseconds usually gets the green light, but the lower the better. It is highly doubtful that time sensitive work would be carried out on a system like this, but any non-Xeon product would be able to outperform our setup. Grid Solvers For any theoretical evaluation of physical events, we mathematically track a volume and monitor the evolution of the properties within that volume speed, temperature, concentration. How a property changes over time is defined by the equations of the system, often describing the rate of change of energy transfer, motion, or another Gigabyte GA-7TESM1 Matrox Graphics over time.

The volume can be split a variety of different ways — regularly by squares finite differenceirregularly by squares finite difference with variable distance modifiersirregularly by triangles finite element to name three, although many different methods exist. More often than not the system has a point of action where stuff is happening heat transfer at a Gigabyte GA-7TESM1 Matrox Graphics or a surface bound reactionmeaning that some areas of the system are more important than others and the grid solver should focus on those areas benefits against regular finite difference.

This usually comes at the Gigabyte GA-7TESM1 Matrox Graphics of increased computational difficulty and irregular memory accesses, but affords faster simulation time having to calculate variable distance points rather than 1 million as an example of a simulation volume. Boundary conditions can also affect the simulation — because the volume being simulated is finite with edges, the action at those edges has to be determined. The volume may be one unit of a whole, making the boundary a repeating boundary entering one side comes out the othera reflecting boundary rate of change at the boundary is zeroa sink boundary is Gigabyte GA-7TESM1 Matrox Graphics 0an input boundary is constantly 1 or a reactive zone rate of change is defined by kinetics or another property — again, there are many more boundary conditions depending on the simulation at hand.

However as the boundary conditions have to be treated differently, this can cause extended memory reads, additional calculations at various points, or fewer calculations by virtue of constant values.


A final point to make is dealing with simulations involving time. By their nature, explicit simulations are embarrassingly parallel but have restricted conditions based on time step and node size — implicit simulations are only slightly parallel, require larger memory jumps but have several fewer restrictions that allow more to be simulated in less time. Deciding between these two methods is often one of the first decisions when it comes to the sorts of simulation I will be testing. All of Gigabyte GA-7TESM1 Matrox Graphics simulations used in this article were described in our previous GA-7PESH1 review in terms of both mathematics and code.

For the sake of brevity, please refer back to that article for more information. Explicit Finite Difference For any grid of regular nodes, the simplest way to calculate the next time step is to use the values of those around it.


This makes for easy mathematics and parallel simulation, as each node calculated is only dependent on the previous time step, not the nodes Gigabyte GA-7TESM1 Matrox Graphics it on the current calculated time step. By choosing a regular grid, we reduce the levels of memory access required for irregular grids.

We test both 2D and 3D explicit finite difference simulations with 2n nodes in each dimension, using OpenMP as the threading operator in single precision. The grid is isotropic and the boundary conditions are sinks. The 6-core Xs in this situation definitely perform lower than the 8-core Es, although with the Xs it pays to have HyperThreading turned off or face 3. In three dimensions, the Es still have the advantage, at 7. With HT disabled, the dual Gigabyte GA-7TESM1 Matrox Graphics system performs The nature of the 3D simulation tends towards a single CPU system performing much better, however. Implicit Finite Difference with the Alternating Direction Implicit method The implicit method takes a different approach to the explicit method — instead of considering one unknown in the new time step to be calculated from known elements in the previous time step, we consider that an old point can influence several new points by way of simultaneous equations.

This adds to the complexity of the simulation — the grid of nodes is solved as a series of rows and columns rather than points, reducing the parallel nature of the simulation by a dimension and drastically increasing the memory requirements of each Gigabyte GA-7TESM1 Matrox Graphics. The upside, as noted above, is the less stringent stability rules related to time steps and grid spacing. For this we simulate a 2D grid of 2n nodes in each dimension, using OpenMP in single precision.
