SIZE (pocl-0.13.tar.gz) = 1901208

First part: this is false, this was due to a libtool bug, which is fixed now

Second part: cmp --quiet is long for the -s option, use that since FreeBSD

cmp doesn't have the long option.

dirty hack, pocl-standalone will be installed into stage with

r-xr-xr-x permissions. So writing to it is problemetic. give the file write

permission and take it away after.

Upstream (pre 0.14) will be a lot different

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.

WWW: http://portablecl.org/

When using ICD, make sure you have set the environment variable

OCL_ICD_VENDORS=${PREFIX}/etc/OpenCL/vendors/

properly. Usually, this should point to 

${PREFIX}/etc/OpenCL/vendors/

with ${PREFIX} set to /usr/local in the standard environment.

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.
