I found the pid of my process. I ran taskset on the pid: 

$ taskset -p 2059
pid 2059's current affinity mask: e

What does this affinity mask value "e" mean? I do not see anything about the possible output values in the taskset docs. The man pages are the same as the docs.

The output of taskset is a bitmask unless you specify otherwise. 

taskset --cpu-list -p 2059
pid 2059's current affinity list: 1-3

Use --cpu-list to get more human comprehensible output: 

   -c, --cpu-list
          Specify a numerical list of processors  instead  of  a  bitmask.
          The numbers are separated by commas and may include ranges.  For
          example: 0,5,7,9-11.

    Someone should submit a bug report that this is not the Unix Way. The bitmask should be printed in octal by default. Without the leading `0` just in case that gives the game away. (-: – JdeBP Feb 11 '20 at 19:48
