 The current code uses the Deep1B dataset for demonstration purposes, but can scale to 1000x larger.
 To run it, download the Deep1B dataset as explained [here](../#getting-deep1b), and edit paths to the dataset in the scripts. 
 
+The cluster commands are written for the Slurm batch scheduling system. 
+Hopefully, changing to another type of scheduler should be quite straightforward.

 ## Distributed k-means
 
 To cluster 500M vectors to 10M centroids, it is useful to have a distriubuted k-means implementation.

 ## Building the index by slices
 
-We call the slices "vslisces" as they are vertical slices of the big matrix (see explanation in the wiki section [Split across datanbase partitions](https://github.com/facebookresearch/faiss/wiki/Indexing-1T-vectors#split-across-database-partitions)

 The script [make_index_vslice.py](make_index_vslice.py) makes an index for a subset of the vectors of the input data and stores it as an independent index. 
 There are 200 slices of 5M vectors each for Deep1B.
