Abstract: In an embodiment, a computation engine may perform dot product computations on input vectors. The dot product operation may have a first operand and a second operand, and the dot product may be performed on a subset of the vector elements in the first operand and each of the vector elements in the second operand. The subset of vector elements may be separated in the first operand by a stride that skips one or more elements between each element to which the dot product operation is applied. More particularly, in an embodiment, the input operands of the dot product operation may be a first vector having second vectors as elements, and the stride may select a specified element of each second vector.

Abstract: A novel method for updating a bundle of files from an update package that minimize the free space requirement on disk is provided. The method segments the update of the entire package and performs the update in multiple passes. The method divide the archive payload of the entire update package into pieces and expand one piece of the archive in each pass. At the end of each pass, some embodiments remove from the disk the archive piece expanded in that pass in order to free additional space for the next pass.

Abstract: A novel software updating method is provided. A target file is divided into segments, where some segments are updated by patching, while other segments are updated by archiving. The segmentation of the update allows very large files such as DYLD shared caches to be patched in-place, i.e., by using free space available within the file to perform patching rather than requiring enough free space on disk to store both the new version and the old version of the file. The segmentation of the update also allows each segment to be updated individually by the most optimal update method (copy, patch, or archive) so that the size of the update file can be minimized.
