Choosing TP_PASSES - Choosing TP_PASSES - 2026.1 English

TP_PASSES directly controls the accuracy of the decomposition. As a guide:

• 3-5 passes typically suffice for well-conditioned matrices.
• More passes may be needed for ill-conditioned matrices or when high accuracy of U is required.
• Fewer passes reduce latency and resource use at the cost of accuracy.

Singular values in the output S vector are sorted in descending order, with the columns of U and V permuted consistently. V is orthonormal by construction regardless of pass count; the orthonormality of U improves with each additional pass.
