ocl-icd-dev 2.3.2-1 (s390x binary) in ubuntu mantic

 OpenCL (Open Computing Language) is a multivendor open standard for
 general-purpose parallel programming of heterogeneous systems that include
 CPUs, GPUs and other processors.
 .
 This package provides a header file that allows an OpenCL implementation
 to build an installable client driver (ICD). With an ICD, an OpenCL
 implementation can be used by any OpenCL program without the need
 to link the program to the specific OpenCL implementation.
 .
 For building OpenCL applications, install the ocl-icd-opencl-dev package
 instead.
