Hello world using Epiphany BSP

This example shows how to write a simple "Hello world!" program using Epiphany BSP.

Epiphany BSP is a library for developing applications for the Parallella board. It is easy to setup and use, and provides powerful mechanisms for writing optimized parallel programs. Detailed documentation is provided at http://www.codu.in/ebsp/docs.

Building

This example requires the Epiphany BSP library. Building the example consists of three steps:

1. Obtaining the Epiphany BSP library by cloning the code from GitHub.
2. Building the library. This will compile the EBSP library, which is used for the example.
3. Building the example. This will compile the host program and a kernel.

These three steps can be performed by simply issuing:

make

from the command line.

Manually building

If instead you prefer to perform each steps separately, then issue:

git clone https://github.com/coduin/epiphany-bsp

From the command line. To build the library issue:

make ebsp

from this examples' directory. Finally to build the example run:

make example

Running

To run the example:

./bin/host_hello

It will load the kernel ecore_hello on each Epiphany core. You should see the following output:

$08: Hello World from processor 8 / 16
$01: Hello World from processor 1 / 16
$07: Hello World from processor 7 / 16
...
