Row sums of a GPU-resident handle

Source: R/resident-handle.R
rh_rowSums.Rd

Computes row sums of the matrix stored in a resident_handle, using a GPU-resident reduction when the backend supports it to avoid a round-trip download. Falls back to base::rowSums on the materialized matrix when no resident reduction is available.

Usage

rh_rowSums(h)

Arguments

h

A resident_handle.

Value

Numeric vector of length nrow(h).
