  • The OpenCLLink application must be loaded using Needs["OpenCLLink`"].
  • Valid types are:
  • IntegerRealComplex
    "Byte""Bit16""Integer"
    "Byte[2]""Bit16[2]""Integer32[2]"
    "Byte[4]""Bit16[4]""Integer32[4]"
    "Byte[8]""Bit16[8]""Integer32[8]"
    "Byte[16]""Bit16[16]""Integer32[16]"
    "UnsignedByte""UnsignedBit16""Float"
    "UnsignedByte[2]""UnsignedBit16[2]""Float[2]"
    "UnsignedByte[4]""UnsignedBit16[4]""Float[4]"
    "UnsignedByte[8]""UnsignedBit16[8]""Float[8]"
    "UnsignedByte[16]""UnsignedBit16[16]""Float[16]"
    "Double""Double[2]""Double[4]"
    "Double[8]""Double[16]"
  • OpenCLMemory can be queried using OpenCLMemoryInformation.
  • OpenCLMemory is retrieved using OpenCLMemoryGet.
  • OpenCLMemory is unloaded using OpenCLMemoryUnload.
  • is used when memory needs to be allocated to be written to, such as output memory.
  • The following options can be given:
  • "Device"AutomaticOpenCL device used in computation
    "Platform"AutomaticOpenCL platform used in computation
    "TargetPrecision"Automaticprecision used in computation

First, load the OpenCLLink application:

In[1]:=
Click for copyable input

This allocates memory and registers it with the OpenCLLink memory manager:

In[2]:=
Click for copyable input
Out[2]=

This allocates a rank-3 tensor into the OpenCLLink memory manager:

In[3]:=
Click for copyable input
Out[3]=

This returns information on the memory allocated:

In[4]:=
Click for copyable input
Out[4]=

When using the type , whether it is a or is based on the OpenCL device:

In[1]:=
Click for copyable input
Out[1]=

In this case, the system supports double precision. This can be overridden using the option:

In[2]:=
Click for copyable input
Out[2]=
