@paul-rogers Paul, Thanks a lot for your review comments and bringing up
some good issues. Just want to let you know. I am working on refactoring the
batch sizer code, writing bunch of unit tests to test sizing and vector
allocation for all different vector types. Found some bugs in the process and
fixed them. I will be posting new changes soon and need your review once they
are ready.---
