Description
status
int
Current status of the task.
Description
The
vslConvSetStart
/
vslCorrSetStart
 routine sets the value of the parameter
start
 for the operation of convolution or correlation. In a one-dimensional case, this parameter points to the first element in the mathematical result that should be stored in the output array. In a multidimensional case,
start
 is an array of indices and its length is equal to the number of dimensions specified by the parameter
dims
. For more information about the definition and effect of this parameter, see Data Allocation.
During the initial task descriptor construction, the default value for
start
 is undefined and this parameter is not used. Therefore the only way to set and use the
start
 parameter is via assigning it some value by one of the
vslConvSetStart
/
vslCorrSetStart
 routines.

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
