# TESTING NOTE: An OpenCL device is needed to run the tests.  Since the koji
# builders may or may not have a GPU, we use the CPU-only POCL implementation.
# However:
# - POCL is not available on ppc64le or s390x due to failing tests.
# - Builds with POCL on 32-bit ARM fail with an undefined symbol error:
#   __gnu_f2h_ieee.  This symbol is defined in libLLVM, but we are building
#   with gcc/g++, not clang.  Since POCL is built with clang, this appears to
#   be a POCL or clang bug.
# - Builds with POCL on aarch64 fail one DAXPY test, not yet diagnosed.
# - Builds with POCL on i686 often fail due to memory exhaustion.
# That leaves x86_64 as the only platform that can run the tests.

%description
CLBlast is a modern, lightweight, performant and tunable OpenCL BLAS
library written in C++11.  It is designed to leverage the full
performance potential of a wide variety of OpenCL devices from different
vendors, including desktop and laptop GPUs, embedded GPUs, and other
accelerators.  CLBlast implements BLAS routines: basic linear algebra
subprograms operating on vectors and matrices.  See the CLBlast website
for performance reports on various devices as well as the latest CLBlast
news.

The library is not tuned for all possible OpenCL devices: if
out-of-the-box performance is poor, please run the tuners first.
