[Kratos] ANNOUNCEMENT: new opencl application

[Riccardo Rossi]

Hello everyone,
        
          i am writing you to inform that i just committed a new
        "OpenCLApplication", which is designed to provide some portable
        (CPUs,
        ATI gpus, NVIDIA gpus) support for GPU/CPUs acceleration.
        
        As of now, we provide an interface to the linear solvers
        provided by the
        ViennaCL library, developed by Karl Rupp and others at the
        Vienna TU.
        
        A very basic howto that describes how to install and the basic
        usage is
        provided at the address
        
        http://kratos.cimne.upc.es/kratoswiki/index.php/HOW_TOs
        --> How to use the OpenCL linear solvers
        
        all the files needed will download with a simple 
        
          svn update
        
        of the kratos repository. Installation of the opencl compiler
        will be
        needed but is automatic on recent ubuntus.
        
        the application is still experimental, however the installation
        should
        be pretty straightforward and from the initial tests it appears
        to work
        satisfactorily
        
        please give me feedback on the subject
        
        ciao
        Riccardo
