# F2 (schur_recursive_inverse_plan.txt 4C): the full DenseCoarseMatrix
|
|
# glue on GPU with a REAL coarsening -- DWF MdagM + 0.5 shift, random
|
|
# aggregation nbasis=4, per-dim blocks {4,4,3,3}, coarse 3.3.4.4/rank
|
|
# (N = 576 * nranks). The test binary FORCES DENSE_SCHUR=2 audit mode
|
|
# and DENSE_PANEL_BYTES=65536 internally (setenv in main), so both
|
|
# invert paths run and are compared on the same imported A; multi-chunk
|
|
# panel gathers are exercised through the glue.
|
|
#
|
|
# First GPU execution in anger of: GRID_SIMT-guarded CoarsenOperator
|
|
# population kernel; fresh stencil->dense import (fp32 + fp64) with the
|
|
# transposed-contraction fix; fp64 rank-major import; distributed fp64
|
|
# recursion; single terminal fp32 rounding; boss rocSOLVER single-GCD
|
|
# path as the audit oracle.
