Custom partitioning among workers

[Akshay Trivedi]

Hi all,
I need help on partitioning graph. I input the graph and label it. Now
I want that all vertices with same label are assigned to a worker and
no other vertices with different labels are assigned to the same
worker. In this way each group of vertices having same label are
assigned to an unique worker. Can anyone help me with this.
         Thank you in advance

Regards
Akshay
