/***************************************************************************
The ucl_copy and ucl_cast_copy routines provide a general prototype for
copying data between host and device memory (including texture memory)
for the matrix and vector types in nvc_memory.
For host/host and host/device transfers, typecasting is performed
automatically as necessary.
The routines are written so that all branches can be removed by the
compiler during template instantiation.
The routines currently assume row-major ordering for all types.
For asynchronous copy in the default command queue, async is boolean true;
For asynchronous copy in a specified command queue, async is command queue
Otherwise, set async to boolean false;
When performing frequent data copies that require casting, it is more
efficient to allocate a casting buffer once and then pass that buffer
to the copy routine. This can be accomplished with the ucl_cast_copy
routines.
Examples
(x's represent alignment padding - to maintain alignment)
(o's represent a larger matrix in memory)
(vectors represented as single row)
