j_max

int quda::BiCGstabLUpdate::j_max

private

On a BiCG iteration j, u[0] through u[j-1] need to get updated, similarly r[0] through r[j-1] need to get updated. j_max = j.

Referenced by apply(), and update_j_max().

n_update

int quda::BiCGstabLUpdate::n_update

private

How much to partition the shifted update. For now, we assume we always need to partition into two pieces (since BiCGstab-L should only be getting even/odd preconditioned operators).
