  • I think -k 1048576 means $1048576 \times 1024 = 1073741824$ bytes.
  • I think BlaMka (modified Blake2b) has a block size of $512$ bytes in Argon2.
  • I think -t 20 means repeat the work on the entire $1073741824$ bytes memory pad for $20$ times.

So, I think, the total number of times BlaMka is called is:

$$ 20\frac{1073741824}{512} = 41,943,040 $$
