While GPUs can have hundreds or even thousands of stream processors, they each run slower than a CPU core and have fewer features even if they are Turing complete and can be programmed to run any program a CPU can run. Features missing from GPUs include interrupts and virtual memory, which are required to implement a modern operating system. In other words, CPUs and GPUs have significantly different architectures that make them better suited to different tasks.
A GPU can handle large amounts of data in many streams, performing relatively simple operations on them, but is ill-suited to heavy or complex processing on a single or few streams of data. A CPU is much faster on a per-core basis in terms of instructions per second and can perform complex operations on a single or few streams of data more easily, but cannot efficiently handle many streams simultaneously.
As a result, GPUs are not suited to handle tasks that do not significantly benefit from or cannot be parallelized, including many common consumer applications such as word processors. Furthermore, GPUs use a fundamentally different architecture; one would have to program an application specifically for a GPU for it to work, and significantly different techniques are required to program GPUs.
These different techniques include new programming languages, modifications to existing languages, and new programming paradigms that are better suited to expressing a computation as a parallel operation to be performed by many stream processors.
For more information on the techniques needed to program GPUs, see the Wikipedia articles on stream processing and parallel computing. Modern GPUs are capable of performing vector operations and floating-point arithmetic, with the latest cards capable of manipulating double-precision floating-point numbers. Consumers with modern GPUs who are experienced with Folding home can use them to contribute with GPU clients , which can perform protein folding simulations at very high speeds and contribute more work to the project be sure to read the FAQs first, especially those related to GPUs.
Why Parallelize a Wave Equation Solver? Wave equations are used in a wide range of engineering disciplines, including seismology, fluid dynamics, acoustics, and electromagnetics, to describe sound, light, and fluid waves.
An algorithm that uses spectral methods to solve wave equations is a good candidate for parallelization because it meets both of the criteria for acceleration using the GPU see "Will Execution on a GPU Accelerate My Application? It is computationally intensive. The exact number depends on the size of the grid Figure 2 and the number of time steps included in the simulation.
Each time step requires two FFTs and four IFFTs on different matrices, and a single computation can involve hundreds of thousands of time steps. It is massively parallel.
The parallel FFT algorithm is designed to "divide and conquer" so that a similar task is performed repeatedly on different data. Additionally, the algorithm requires substantial communication between processing threads and plenty of memory bandwidth. The IFFT can similarly be run in parallel. A GPU can accelerate an application if it fits both of the following criteria: Computationally intensive—The time spent on computation significantly exceeds the time spent on transferring data to and from GPU memory.
Massively parallel—The computations can be broken down into hundreds or thousands of independent units of work. These GPU-enabled functions are overloaded—in other words, they operate differently depending on the data type of the arguments passed to them. For example, the following code uses an FFT algorithm to find the discrete Fourier transform of a vector of pseudorandom numbers on the CPU: Then we can run fft, which is one of the overloaded functions on that data: The result, B, is stored on the GPU.
For example, to visualize our results, the plot command automatically works on GPUArrays: In this simple example, the time saved by executing a single FFT function is often less than the time spent transferring the vector from the MATLAB workspace to the device memory.
This is generally true but is dependent on your hardware and size of the array. Data transfer overhead can become so significant that it degrades the application's overall performance, especially if you repeatedly exchange data between the CPU and GPU to execute relatively few computationally intensive operations.
It is more efficient to perform several operations on the data while it is on the GPU, bringing the data back to the CPU only when required2.
However, unlike CPUs, they do not have the ability to swap memory to and from disk. Thus, you must verify that the data you want to keep on the GPU does not exceed its memory limits, particularly when you are working with large matrices. By running gpuDevice, you can query your GPU card, obtaining information such as name, total memory, and available memory.
We use an algorithm based on spectral methods to solve the equation in space and a second-order central finite difference method to solve the equation in time. Spectral methods are commonly used to solve partial differential equations. With spectral methods, the solution is approximated as a linear combination of continuous basis functions, such as sines and cosines.
In this case, we apply the Chebyshev spectral method, which uses Chebyshev polynomials as the basis functions. Using these derivatives together with the old solution and the current solution, we apply a second-order central difference method also known as the leap-frog method to calculate the new solution.
We choose a time step that maintains the stability of this leap-frog method. The MATLAB algorithm is computationally intensive, and as the number of elements in the grid over which we compute the solution grows, the time the algorithm takes to execute increases dramatically. When executed on a single CPU using a x grid, it takes more than a minute to complete just 50 time steps.
