low cost stack for function call?

can the stacking operation of the dag chasing be reduced so the overhead is minimized?

clapack3.1.1 blas testing handtune

in the testing routines, eps is wrongly calculated as 1e-19, which should be 1e-7. In each files (dblat3.c, for example), a new piece of eps code is inserted.

For double precision (complex16), problem exists for not accurate element result.

a recall of all the work that I've done

(1) Complex version SVD for ScaLAPACK

(2) RFP for LAPACK

(3) Performance comparison between PLAPACK & SCALAPACK

(4) Re-write PDGETRF, optimization with look-ahead and other threading method for better performance on multi-core cluster

(5) CELL learning

(6) Variations of LU, Chol and QR for LAPACK

(7) CLAPACK conversion

(8) ScaLAPACK auto-tuning

(9) DAG automatic generation for LAPACK

(10) Using random butterfly transformation to remove pivoting

(11) ILP64 support for LAPACK, ScaLAPACK

(12) tiled LU without pivoting
