These invalidation messages increase network traf-fic. In order to avoid reading the lattices entries multiple times from the global memory, each block initially loads its spin tile from the source lattice into the shared memory, and then the threads load the words containing their neighboring spins from that faster memory space. Then be able to do common operations on a subtree of repos, like mr status, mr update, mr diff, or really anything. Otherwise, you can manually map a shared folder using net use [Drive_Letter]: \\server\share command where server is your File Server Name or IP, share is your share name and [Drive_Letter] is the letter of your new drive (Example: Z:). A process can attach a shared memory segment to the virtual address within its address space and then access the segment as if it were part of its normal address space without the need for any additional system calls.
