Detailed Description

Structure containing matrices for multi-GPU dgehrd.

  • dA is distributed column block-cyclic across GPUs.
  • dV is duplicated on all GPUs.
  • dVd is distributed row block-cyclic across GPUs (TODO: verify).
  • dY is partial results on each GPU in dlahr2, then complete results are duplicated on all GPUs for dlahru.
  • dW is local to each GPU (workspace).
  • dTi is duplicated on all GPUs.
