Hi,
I need to record the range of a subarray in a struct in order to define a padded-array.
However I have troubles using indexing in CuArrays.jl
. Basically, the only solution which works is to use things like u[1:10,1:10] .= v
but if I want to consider different array dimensions, I have to rewrite the code.
Am I missing a point?
If somebody can give a hint, I would be gratefull,
Thank you,
Bests.
using CuArrays
N = 100
CuArrays.allowscalar(false)
u = CuArrays.CuArray(rand(N,N))
v = CuArrays.CuArray(rand(10,10))
u[1:10,1:10] ;#OK
u[1:10,1:10] .= v ;#OK
rang = CartesianIndices((1:10,1:10))
u[rang]; #error
u[rang] .= v ;#error
rang = LinearIndices((1:10,1:10))
u[rang]; #OK
u[rang] .= v ;#error
rang = (1:10,1:10)
u[rang[1],rang[2]].=v; #works but what if I want to consider 3d arrays?
