## Building the Exercises



The exercises can be built for DPC++ and AdaptiveCpp.



### Supported Platforms



Below is a list of the supported platforms and devices for each SYCL implementations,

please check this before deciding which SYCL implementation to use.

Make sure to also install the specified version to ensure that you can build

all of the exercises.



| Implementation | Supported Platforms | Supported Devices | Required Version |

|----------------|---------------------|-------------------|------------------|

| DPC++ | [Intel DevCloud](#connecting-to-devcloud-via-ssh) 
 Windows 10 Visual Studio 2019 (64bit) 
 Red Hat Enterprise Linux 8, CentOS 8

| AdaptiveCpp | Any Linux | CPU (OpenMP) 
 AMD GPU (ROCm)*** 
 NVIDIA GPU (CUDA)
 Intel GPU (Level Zero)
 Intel CPU, GPU (OpenCL) | 23.10.0 from Nov 1, 2023 or newer |



\* Supported in open source project only



\*\* See [here][rocm-gpus] for the official list of GPUs supported by AMD for

ROCm. We do not recommend using GPUs earlier than gfx9 (Vega 10 and Vega 20

chips).



### Install SYCL implementations



First you'll need to install your chosen SYCL implementation and any

dependencies they require.



#### Installing DPC++



To set up DPC++ follow the [getting started instructions][dpcpp-getting-started].



You can also use a [Docker* image][docker-container-oneapi].



If you are using the [Intel DevCloud][intel-devcloud] then the latest version of DPC++ will

already be installed and available in the path.



#### Installing AdaptiveCpp



You will need a AdaptiveCpp (formerly hipSYCL) build from September 2021 or newer. Refer to the [AdaptiveCpp installation instructions][adaptivecpp-installing] for details on how to install AdaptiveCpp.



### Pre-requisites



Before building the exercises you'll need:



* One of the platforms in the support matrix above, depending on which SYCL

implementation you are wishing to build for.

* A C++17 or above tool-chain.

* An appropriate build system for the platform you are targeting (CMake, Ninja,

Make, Visual Studio).



### Configuring using CMake



Clone this repository, there are some additional dependencies configured as git

sub-modules so make sure to clone those as well. Then simply invoke CMake as

follows:



```

mkdir build



cd build



cmake ../ -G -A -D=ON

```



For `` / `` we recommend:



* Visual Studio 16 2019 / x64 (Windows)

* Ninja / NA (Windows or Linux)

* Make / NA (Linux) i.e. "-GUnix Makefiles"



For `sycl_implementation` this can be one of:



* `SYCL_ACADEMY_USE_ADAPTIVECPP`

* `SYCL_ACADEMY_USE_DPCPP`



You can also specify the additional optional options:



```

-DSYCL_ACADEMY_INSTALL_ROOT=

```



For `` we recommend you specify the path to the

root directory of your SYCL implementation installation, though this may not

always be required.



```

-DSYCL_ACADEMY_ENABLE_SOLUTIONS=ON

```



This will enable building the solutions for each exercise as well as the source

files. This is disabled by default.



```

-DCMAKE_BUILD_TYPE=Release

```



The build configuration for all exercises defaults to a debug build if this option is not specified.



#### Additional cmake arguments for DPC++



```

-DCMAKE_C_COMPILER=icx -DCMAKE_CXX_COMPILER=icpx

```



This SYCL Academy CMake configuration uses the Intel oneAPI IntelSYCL CMake module package to assist it in its configuration. These command line arguments must be used to initiate this configuration correctly.



`-DSYCL_TRIPLE` can be used to specify a DPC++ compatible SYCL triple. Possible

values include:



* `amdgcn-amd-amdhsa` - For AMD devices

* `nvptx64-nvidia-cuda` - For CUDA devices

* `spir64_gen` - For Intel GPUs

* `native_cpu` - For native CPU SYCL device (dependent on DPCPP version)



`-DSYCL_ARCH` can also be used to specify a device arch. This CMake opt is

necessary for AMD. Possible values include:



* `gfx90a` - For AMD MI200

* `sm_80` - For NVIDIA A100

* `pvc` - For Intel PVC



It may also be necessary to manually specify the install location of the CUDA or

ROCM SDK, if this is found in a non-standard location. The flags:



`-DROCM_DIR` and `-DCUDA_DIR` can be used to specify the install dir of the ROCM

or CUDA SDKs, respectively.



##### DPC++ for AMD CMake example



```

  cmake .. -GNinja -DSYCL_ACADEMY_USE_DPCPP=ON -DSYCL_ACADEMY_ENABLE_SOLUTIONS=ON -DCMAKE_C_COMPILER=icx -DCMAKE_CXX_COMPILER=icpx _DSYCL_TRIPLE=amdgcn-amd-amdhsa -DSYCL_ARCH=gfx90a -DROCM_DIR=/opt/rocm/5.4.3

```



##### DPC++ for CUDA CMake example



```

  cmake .. -GNinja -DSYCL_ACADEMY_USE_DPCPP=ON -DSYCL_ACADEMY_ENABLE_SOLUTIONS=ON -DCMAKE_C_COMPILER=icx -DCMAKE_CXX_COMPILER=icpx _DSYCL_TRIPLE=nvptx64-nvidia-cuda -DSYCL_ARCH=sm_61 -DCUDA_DIR=/usr/local/cuda/11.2/

```



#### Additional cmake arguments for AdaptiveCpp



Sufficiently new (>= 24.02.0), full installations of AdaptiveCpp do not require specifying compilation targets.

In this case, targets may still be provided optionally. 



For older AdaptiveCpp versions, CMake will require you to specify the compilation targets using `-DACPP_TARGETS=`. 



`` is a list of compilation flows to enable and devices to target, for example

`-DACPP_TARGETS="omp;generic"` compiles for CPUs using OpenMP and GPUs using the generic single-pass compiler.



If your AdaptiveCpp installation does not force a compilation target to be provided, but it was built with the generic single-pass compiler disabled (it is enabled by default in all AdaptiveCpp installations built against LLVM >= 14), it is compiling for a default set of targets provided at installation time. If you cannot run the binary on the hardware of your choice, this default set may not be the right one for your hardware and you may have to specify the right targets explicitly.



Available compilation flows are:

* `omp` - OpenMP CPU backend

* `generic` - Generic single-pass compiler. Generates a binary that runs on host CPU, AMD, NVIDIA and Intel GPUs using runtime compilation

* `cuda` - CUDA backend for NVIDIA GPUs. Requires specification of targets of the form sm_XY, e.g. sm_70 for Volta, sm_60 for Pascal. E.g: `cuda:sm_70`.

* `hip`  - HIP backend for AMD GPUs. Requires specification of targets of the form gfxXYZ, e.g. gfx906 for Vega 20, gfx900 for Vega 10. E.g.: `hip:gfx906`.



When in doubt, use `-DACPP_TARGETS=generic` as it compiles the fastest, usually generates the fastest binaries, and generates portable binaries.



#### CMake usage example



Invoking CMake from the command line example usage:

```

  cmake .. "-GUnix Makefiles" -DSYCL_ACADEMY_USE_DPCPP=ON -DSYCL_ACADEMY_ENABLE_SOLUTIONS=ON -DCMAKE_C_COMPILER=icx -DCMAKE_CXX_COMPILER=icpx

```



### Getting started with compiling DPC++



First you have to ensure that your environment is configured to use DPC++ (note

if you are using the Intel DevCloud then you don't need to do this step).



On Linux simply call the `setvars.sh` which is available in `/opt/intel/oneapi`

for sudo or root users and ~/intel/oneapi/ when installed as a normal user.



For root or sudo installations:

`source /opt/intel/oneapi/setvars.sh`



For normal user installations:

`source ~/intel/oneapi/setvars.sh`



On Windows the script is located in  `\setvars.bat`



Where `` is wherever the `oneAPI` directory is installed.



Once that's done you can invoke the DPC++ compiler as follows:



`icpx -fsycl -o a.out source.cpp`



Where `` is the path to the root directory of where you cloned

this repository. Note that on Windows you need to add the option /EHsc to avoid exception handling error.



The CMake configuration can also be used to build the exercises, see the section **Configuring using CMake** above.



## Working on the Exercises

Once you have a working SYCL compiler, you are ready to start writing some SYCL code. To find the first exercise:

```

cd Code_Exercises/Compiling_with_SYCL/

```

And read the README.md for further instructions.



Each exercise directory contains:

* ```README.md```, which contains instructions of how to complete a given exercise, as well as directions for compilation.

* ```source.cpp```, a placeholder file where your code implementation should be written.

* ```solution.cpp```, where a solution has been implemented in advance.



Once you have completed any given exercise make sure to compare your implementation against the corresponding ```solution.cpp```.



## Online Interactive Tutorial



Hosted by tech.io, this [SYCL Introduction](https://tech.io/playgrounds/48226/introduction-to-sycl/introduction-to-sycl-2) tutorial introduces the concepts of SYCL. The website also provides the ability to compile and execute SYCL code from your web browser.



## Connecting to DevCloud via SSH



* Start by creating an [Intel DevCloud account][intel-devcloud] account if you do not already have one and login in.

* Initialize the SSH configuration by clicking on [Automated Configuration](https://devcloud.intel.com/oneapi/documentation/connect-with-ssh-linux-macos/) and follow the instructions to setup the SSH configuration file.

* SSH into DevCloud (```ssh devcloud```)



## Connect to DevCloud via Jupyter Notebooks



* Start by creating an [Intel DevCloud account][intel-devcloud] account if you do not already have one and login in.

* Go to [training](https://console.cloud.intel.com/training) and click on ```Launch JupyterLab´´´

* In the ```Jupiter Notebook``` select *File->New->Terminal*



You are now ready to start with the first [lesson][lesson-1-slides]. Enjoy !
