#----------------------------------------------------------------------
# Survey of known allocatable memory as reported to hashcat by OpenCL.
# Varies by OpenCL runtime family (NVIDIA, AMD, Intel, pocl, etc.) and version.
# Triggered by curiosity about OpenCL maximum memory allocation.
# Compiled by Royce Williams / @tychotithonus
# As referenced in https://devtalk.nvidia.com/default/topic/992502/cuda-programming-and-performance/why-is-cl_device_max_mem_alloc_size-never-larger-than-25-of-cl_device_global_mem_size-only-on-nvidia-/

# Commentary:
# 
# In the OpenCL specification:
# 
# https://www.khronos.org/registry/OpenCL/specs/opencl-1.2.pdf
# 
# ... the CL_DEVICE_MAX_MEM_ALLOC_SIZE value controls how much GPU memory is available for allocation. Quoting the spec:
# 
# "CL_DEVICE_MAX_MEM_ALLOC_SIZE - Max size of memory object allocation in bytes. The minimum value is max (1/4th of CL_DEVICE_GLOBAL_MEM_SIZE, 128*1024*1024) for devices that are not of type CL_DEVICE_TYPE_CUSTOM."
# 
# This phrasing is potentially confusing, Paraphrased, it says:
# 
# "When implementing OpenCL, CL_DEVICE_MAX_MEM_ALLOC_SIZE must be set in order to inform applications about maximum allocatable memory. To be compliant with this specification, this maximum must be either either one fourth of the device's physical memory (CL_DEVICE_GLOBAL_MEM_SIZE) or 128 binary megabytes, whichever is greater."
# 
# This defines the minimum for CL_DEVICE_MAX_MEM_ALLOC_SIZE. The specification does not define how to calculate a maximum for CL_DEVICE_MAX_MEM_ALLOC_SIZE.
# 
# In most (if not all) NVIDIA OpenCL implementations, this value appears to be applied as a *maximum* for allocatable memory.
# For all known NVIDIA OpenCL-compatible cards in this survey, allocatable memory appears to be artificially constrained to only 25% of physical memory. It is sometimes less, but it appears to *never* be more.
# 
# By contrast, some AMD and Intel implementations appear to work from a higher limit, 2.7 or 2.8 out of 4 GB, or sometimes close to 100% of physical memory. Some pocl implementations also appear to make the maximum physical amount fully available for OpenCL.
