Abstract: This invention relates to the in situ process for converting non-free-form xanthophylls to free xanthophylls in the biological material of the plant. The method, more particularly, relates to a method that would liberate xanthophylls by transesterification of acyl-xanthophylls in plant materials which is used as a natural food colorant.

Abstract: An apparatus and method for efficiently mapping elements of an array to processing elements (PEs) of a parallel data computer. Axis lengths and weights are received from a compiler (if invoked at compile time) or an application program (if invoked at run time). A physical grid is generated by expanding the axis lengths so that their product is integrally divisible by "machine.sub.-- bits" (i.e., log.sub.2 (number of PEs on the data parallel computer)). The physical grid is divided into subgrids of equal size by dividing each expanded axis length into subgrid lengths of equal length. The lengths and numbers of subgrid lengths in each axis are then output to the compiler or the application program. From the subgrid lengths, the compiler or application program can identify a unique location in one of the subgrids given any location of an element in the array.
