OPENCLLINK SYMBOL
OpenCLMemoryAllocate
allocates a new one-dimensional list of type t returning OpenCLMemory.
allocates a new list of dimensions 
type t returning OpenCLMemory.
Details
- The OpenCLLink application must be loaded using Needs["OpenCLLink`"].
- Valid
types are: -
Integer Real Complex "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" Automatic OpenCL device used in computation "Platform" Automatic OpenCL platform used in computation "TargetPrecision" Automatic precision used in computation

Basic Examples (2)
First, load the OpenCLLink application:
| In[1]:= |
This allocates memory and registers it with the OpenCLLink memory manager:
| In[2]:= |
| Out[2]= |  |
This allocates a rank-3 tensor into the OpenCLLink memory manager:
| In[3]:= |
| Out[3]= |  |
This returns information on the memory allocated:
| In[4]:= |
| Out[4]= |  |
When using the type 
, whether it is a 
or 
is based on the OpenCL device:
| In[1]:= |
| Out[1]= |  |
In this case, the system supports double precision. This can be overridden using the 
option:
| In[2]:= |
| Out[2]= |  |
