TODO:
|
|
|
|
=> Clean up HMC
|
|
- Reunitarise
|
|
- Reversibility test.
|
|
- Link smearing/boundary conds; Policy class based implementation
|
|
|
|
- Integrators
|
|
- Force Gradient
|
|
- Sign of force term.
|
|
- Prefer "RefreshInternal" or such like to "init" in naming
|
|
- Rename "Ta" as too unclear
|
|
DONE: -- pass GaugeField as template param.
|
|
-- LorentzScalar<GaugeField> gets Gauge link type (cleaner).
|
|
-- Simplified the integrators a bit.
|
|
- Multi-timescale looks broken and operating on single timescale for now.
|
|
FIXED
|
|
|
|
* Support different boundary conditions (finite temp, chem. potential ... )
|
|
* Support different fermion representations?
|
|
- contained entirely within the integrator presently
|
|
|
|
=> Lanczos
|
|
|
|
- Rectangle gauge actions.
|
|
Iwasaki,
|
|
Symanzik,
|
|
... etc...
|
|
|
|
- Prepare multigrid for HMC.
|
|
- Alternate setup schemes.
|
|
|
|
* Parallel io improvements DONE
|
|
- move Plaquette and link trace checks into nersc reader from the Grid_nersc_io.cc test. DONE
|
|
* Support for ILDG --- ugly, not done
|
|
|

*** Hacks and bug fixes to clean up and Audits
|
|
================================================================
|
|
|
|
* Extract/merge/set cleanup ; too many variants; rationalise and call simpler ones
|
|
|
|
* Rewrite core tensor arithmetic support to be more systematic
|
|
= Use #define repetitive sequences to minimise code, decrease line count by thousands possible,
|
|
with more robust and maintainable implementation.
|
|
|
|
* Ensure we ET as much as possible; move unop functions into ET framework.
|
|
- tests with expression args to all functions
|
|
|
|
* FIXME audit
|
|
|
|
* const audit
|
|
|
|
Insert/Extract
|
|
* Replace vset with a call to merge.;
|
|
* care in Gmerge,Gextract over vset .
|
|
* extract / merge extra implementation removal
|
|
* Optimise the extract/merge SIMD routines; Azusa??
|
|
- I have collated into single location at least.
|
|
- Need to use _mm_*insert/extract routines.
|
|
|
|
* Thread scaling tests Xeon, XeonPhi
|
|
|
|
|
|
Not sure of status of this -- reverify. Things are working nicely now though.
|
|
|
|
* Make the Tensor types and Complex etc... play more nicely.
|
|
- TensorRemove is a hack, come up with a long term rationalised approach to Complex vs. Scalar<Scalar<Scalar<Complex > > >
|
|
QDP forces use of "toDouble" to get back to non tensor scalar. This role is presently taken TensorRemove, but I
|
|
want to introduce a syntax that does not require this.
|
|
|
|
- Reductions that contract indices on a site should always demote the tensor structure.
|
|
norm2(), innerProduct.
|
|
|
|
- Result of Sum(), SliceSum // spatial sums
|
|
trace, traceIndex etc.. do not.
|
|
|
|
- problem arises because "trace" returns Lattice<TComplex> moving everything down to Scalar,
|
|
and then Sum and SliceSum to not remove the Scalars. This would be fixed if we
|
|
template specialize the scalar scalar scalar sum and SliceSum, on the basis of being
|
|
pure scalar.
|
|
|
|
Done: Cayley, Partial , ContFrac force terms.
|
|
|
|
DONE
|
|
- PseudoFermions
|
|

|
=> Test DWF HMC
|
|

|
|
|
|
Done:
|
|
- RNG filling from sparser grid, lower dim grid.
|
|
|
|
|
|
DONE

*** Expression template engine: -- DONE

[ -- Norm2(expression) problem: introduce norm2 unary op, or Introduce conversion automatic from expression to Lattice<vobj>
|
|
* Strong test for norm2, conj and all primitive types. -- tests/Grid_simd.cc is almost there
|
|
* Implement where within expression template scheme.
|
|
* Check for missing functionality - partially audited against QDP++ layout
|
|
|
|
// Unary functions
|
|
// cos,sin, tan, acos, asin, cosh, acosh, tanh, sinh, // Scalar<vReal> only arg
