tol |
Numerical tolerance for deciding rank. |
The model is fit using a QR factorization of the input x
. At this
time, that means
Both of x
and y
must be distributed in an identical fashion.
This means that the number of rows owned by each MPI rank should match, and
the data rows x
and labels y
should be aligned. Additionally,
each MPI rank should own at least one row. Ideally they should be load
balanced, so that each MPI rank owns roughly the same amount of data.
A regular vector.
The operation has the same communication as
