+\subsection VariableSizeDataInterface Data Interface with Variable Size
|
|
|

|
|
|
+Tasks are actually allowed to change the size of data interfaces.
|
|
|
+
|
|
|
+The task implementation can just reallocate the buffer during its execution, and
|
|
|
+set the proper new values in the interface structure, e.g. nx, ny, ld, etc. so
|
|
|
+that the StarPU core knows the new data layout. The starpu_data_interface_ops
|
|
|
+structure however then needs to have the starpu_data_interface_ops::dontcache
|
|
|
+field set to 1, to prevent StarPU from trying to perform any cached allocation,
|
|
|
+since the allocated size will vary. An example is available in
|
|
|
+<c>tests/datawizard/variable_size.c</c>
