Add pocl.
Portable OpenCL aims to be an efficient open source (MIT-licensed) implementation of the OpenCL 1.2 standard. pocl uses Clang as an OpenCL C frontend and LLVM for the kernel compiler implementation, and as a portability layer. Thus, if your desired target has an LLVM backend, it should be able to get OpenCL support easily by using pocl. PR: 171914 Submitted by: O.Hartmann <ohartmann@walstatt.org> (based on)

Portable OpenCL (pocl)
|
||||
----------------------
|
||||
|
||||
Portable OpenCL aims to be an efficient open source (MIT-licensed)
|
||||
implementation of the OpenCL 1.2 standard.
|
||||
|
||||
In addition to producing an easily portable open source OpenCL
|
||||
implementation, another major goal of the project is improving
|
||||
performance portability of OpenCL programs with compiler
|
||||
optimizations, reducing the need for target-dependent manual
|
||||
optimizations. At the core of pocl is a set of LLVM passes
|
||||
used to statically parallelize multiple work-items with the kernel
|
||||
compiler, even in the presence of work-group barriers. This enables
|
||||
parallelization of the fine-grained static concurrency in the work
|
||||
groups in multiple ways (SIMD, VLIW, superscalar,...).
|
||||
|
||||
The code base is modularized to allow easy adding of new "device drivers"
|
||||
in the host-device layer. A generic multithreaded "target driver" is
|
||||
included. It allows running OpenCL applications on a host that supports
|
||||
the pthread library with multithreading at the work group granularity.

Deadlocks (freezes) on FreeBSD:
|

|
||||
OpenCL applications using pocl on FreeBSD must be compiled with
|
||||
options CFLAGS+=-pthread or CXXFLAGS+=-pthread, otherwise someone risk
|
||||
that a library may not initialize the threading on BSD independently,
|
||||
even if an ICD loader is used.
