[Numpy-discussion] question about in-place operations

first of all thanks to the developed for bumpy which is very useful. I am building a software that uses numpy+pyopencl for lattice qcd computations. One problem that I am facing is that I need to perform most operations on arrays in place and I must avoid creating temporary arrays (because my arrays are many gigabyte large).
One typical operation is this
a[i] += const * b[i]
What is the efficient way to do is when a and b are arbitrary arrays? const is usually a complex number.
a and b have the same shape but are not necessarily uni-dimensional.
