We present several fast algorithms for multiple addition and prefix sum on the Linear Array with a Reconfigurable Pipelined Bus System (LARPBS), a recently proposed architecture based on optical buses. Our algorithm for adding N integers runs on an N log M-processor LARPBS in O(log* N) time...
We divide the large array into blocks that each can be scanned by a single thread block, scan the blocks, and write the total sum of each block to another array of block sums. We then scan the block sums, generating an array of block increments that that are added to all elements in...
The code to solve the Java prefix sum problem with the Vector API is as follows: intarray[] = { 10, 20, 12, 28, 10, 19, 101, 799 };varvector = IntVector.fromArray(IntVector.SPECIES_PREFERRED, array, 0);System.out.println(vector);vector = vector.add(ve...
The Python Array API spec has a proposal for cumulative_sum, which is a special case of this operation. Also, I noticed that bfill in Xarray uses flip twice, so #114 may be relevant (although it might be more efficient to avoid flip in this case, due to Zarr's regular chunks requirem...
Prefix sums (Creating an array with increasing sum) with Recursion in JavaScript - Consider the following array of numbers −const arr = [10, 5, 6, 12, 7, 1];The sum of its consecutive elements taking one less element in every go will be −[10, 5, 6,
