    Description

      Client currently re-computes the matrices used for computation for each invokation to recover a reidset.

      These matrices only depend on size of dstripe_count and cstripe_count and we should cache them and re-use them instead of recomputing them every time.

      The cost to generate these matrices is fairly small relative to the cost to do the actual compute to recover 1MB stripes so maybe not super urgent.
