Neural accelerators are often characterized with the performance feature “TOPS” — Trillion operations per second. But that alone is not enough. It is important to know how these accelerators work and what else should be considered when making a comparison.

Preamble

This tutorial explains every step in detail. I know the struggle of pre-assumed knowledge to well.

For the more knowledgeable ones, here is the fast version:

  • Install blobfuse on your DSVM with sudo apt-get install blobfuse
  • Create folder for blob on the DSVM with: mkdir ~/mycontainer
  • Mount blob into DSVM…
