i am clustering some points and i am caching the cluster centers. i am using the fetch rop TOP for the cache, but i was wondering if this can be multithreaded even if its one frame cause if i select single frame on the fetch rop i get just one workitem. it would be ideal to multithread this as i am doing 3 clusterings on 7mil points.
is it possible?

The most straight forward way is to make 3 filecaches. You can merge the ropfetch nodes in one stream so then they will cook in parallel.
