# matrixMulCUBLAS - Matrix Multiplication (CUBLAS)
|
|
|
|
## Description
|
|
|
|
This sample implements matrix multiplication from Chapter 3 of the programming guide. To illustrate GPU performance for matrix multiply, this sample also shows how to use the new CUDA 4.0 interface for CUBLAS to demonstrate high-performance performance for matrix multiplication.
|
|
|
|
## Key Concepts
|
|
|
|
CUDA Runtime API, Performance Strategies, Linear Algebra, CUBLAS
|
|
|
|
## Supported SM Architectures

|
## Supported OSes
|
|
|
|
Linux, Windows
|
|
|
|
## Supported CPU Architecture
|
|
|
|
x86_64, ppc64le, armv7l
|
|
|
|
## CUDA APIs involved
|
|
|
|
### [CUDA Runtime API](http://docs.nvidia.com/cuda/cuda-runtime-api/index.html)
|
|
cudaMemcpy, cudaFree, cudaEventSynchronize, cudaEventRecord, cudaMalloc, cudaEventElapsedTime, cudaGetDeviceProperties, cudaEventCreate
|
|
|
|
## Dependencies needed to build/run
|
|
[CUBLAS](../../../README.md#cublas)
|
|
|
|
## Prerequisites
|
|
|
|
Download and install the [CUDA Toolkit 12.3](https://developer.nvidia.com/cuda-downloads) for your corresponding platform.
|
|
Make sure the dependencies mentioned in [Dependencies]() section above are installed.
|
|
|
|
## Build and Run
|
|
|
|
### Windows
|
|
The Windows samples are built using the Visual Studio IDE. Solution files (.sln) are provided for each supported version of Visual Studio, using the format:
|
|
```
|
|
*_vs<version>.sln - for Visual Studio <version>
|
|
```
|
|
Each individual sample has its own set of solution files in its directory:
|
|
|
|
To build/examine all the samples at once, the complete solution files should be used. To build/examine a single sample, the individual sample solution files should be used.
|
|
> **Note:** Some samples require that the Microsoft DirectX SDK (June 2010 or newer) be installed and that the VC++ directory paths are properly set up (**Tools > Options...**). Check DirectX Dependencies section for details."
|
|
|
|
### Linux
|
|
The Linux samples are built using makefiles. To use the makefiles, change the current directory to the sample directory you wish to build, and run make:
|
|
```
|
|
$ cd <sample_dir>
|
|
$ make
|
|
```
|
|
The samples makefiles can take advantage of certain options:
|
|
* **TARGET_ARCH=<arch>** - cross-compile targeting a specific architecture. Allowed architectures are x86_64, ppc64le, armv7l.
|
|
By default, TARGET_ARCH is set to HOST_ARCH. On a x86_64 machine, not setting TARGET_ARCH is the equivalent of setting TARGET_ARCH=x86_64.<br/>
|
|
`$ make TARGET_ARCH=x86_64` <br/> `$ make TARGET_ARCH=ppc64le` <br/> `$ make TARGET_ARCH=armv7l` <br/>
|
|
See [here](http://docs.nvidia.com/cuda/cuda-samples/index.html#cross-samples) for more details.
|
|
* **dbg=1** - build with debug symbols
|
|
```
|
|
$ make dbg=1
|
|
```
|
|
* **SMS="A B ..."** - override the SM architectures for which the sample will be built, where `"A B ..."` is a space-delimited list of SM architectures. For example, to generate SASS for SM 50 and SM 60, use `SMS="50 60"`.
|
|
```
|
|
$ make SMS="50 60"
|
|
```
|
|
|
|
* **HOST_COMPILER=<host_compiler>** - override the default g++ host compiler. See the [Linux Installation Guide](http://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html#system-requirements) for a list of supported host compilers.
|
|
```
|
|
$ make HOST_COMPILER=g++
|
|
```
