bff7e0c389 More performance enhancements to WB2 and WB3. 2021-07-12 16:36:42 +02:00
François Coppens
fa61b50bb0 - Optimize WB3 by inlining matmuls and simplifying copies 
- Occasional code restyling with 'clang-formant --style=LLVM'.

Francois Coppens
43b996dad9 - Added tests/fnu_test_h5.cpp that takes its input cycle numbers from a file instead of from the command line. 
- Suppressed all debug output so as to not polute performance measurements.

67f5379bea - Moved check on determinants in Woodbury kernels before inversion of B that was there by mistake. 
- Split SM2 into SM2 and SM2star so that keeps all updates for later when used in combination with the Woodbury kernels to improve the numerical accuracy to the same level as that of SM2.

7b9b176545 - Replaced the copy-arrays in the combined SMWB kernels with pointers 
- Added loop in test_cycle() to repeat a single update cycle n-times for performance testing.

837e160f17 - Added various Sherman-Morrison-Woodbury kernels 
- Separated debug information into 2 different debug levels.

22590b7684 * Woodburry 3x3 kernel fixed 
* Written Unified Sherman-Morrison-Woodbury kernel that partitions
  the updates in blocks of 3 and tries them with Woodbury 3x3.
  The remainder of 2 or one are attempted with Woodbury 2x2 and SM2.

For now the unified kernel gives fails where pure SM2 does not.
I suspect there is something going wrong in how the updates are partitioned.

f4becac4c0 First implementation of SM4 
SM4: Sherman Morrison, mix between SM3 + SM2
Leave zero denominators for later (SM3), and when none are left then split (SM2)

3ee4d3b56d - Added a small 3x3 example that will always become singular regardles the order of the applied updates. This example is added to test Maponi A3 augmented with Slagel-splitting. 
- Slagel-splitting in Maponi A3 is now working. A thourough analysis on the QMC=Chem datasets still has te be done.
- Acceptance tollerance  in 'test_h5' on the residuals can be set at runtime now.

e3815267fb * Added SM{1,2,3} algorithms to Fortran module 
* Deleted final ylk array in MaponiA3(S)
* Output of Valgrind seem to suggest there are no major memory problems.

991f40a605 Moved common MaponiA3 functions to SM_Helpers.{cpp,hpp} to prepare for MaponiA3+Slagel splitting. 2021-04-14 16:19:49 +02:00

ab9d13180a Small restructuring and cleaning up spurious includes and and namespaces. 2021-04-14 15:32:54 +02:00
Francois Coppens
c2f643ad8f - Updated cleaning target in Makefile 
- Updated gitignore
- Added python script to compute basic statistical observables from testruns
- Added test bash script to automate test_h5: the cycles in the dataset are not continues and test_h5 crashes if a cycle number is not present in the dataset.
- Added common threshold for all 3 standard SM algos.

6cd9fb1072 - Moved transposing of Slater_inv to HDF5 conversion tool and removed it from the test program. 
- Let Maponi A3 continue, even after the algorithm breaks down.

f096db6411 New implementations for Sherman Morisson 
- SM2: Slagel splitting implementation
    (http://hdl.handle.net/10919/52966)

  - SM3: Keep close to zero denominators for later

  - Update tests to show the squared residual

6012b9decf 4x4 with 2 updates example is working again after adding update cycle 8169 dataset but with replacement updates instead of additive updates. 2021-03-12 15:49:02 +01:00
François Coppens
ef97b40196 Changed code to treat the dataset as replacement updates, instead of additive updates. Before the updates are used to compute the inverse they are transformed accordingly. 
However, this breaks the 4x4 example in update cycle 8169.

081fbfc1d8 Loop merge successful. 
Next step: reduce the number of indices of ylk by not keeping
all the previous solutions.

4bd61dd76c Add a standard Sherman-Morisson implementation 
- It can serve as a baseline reference

- It can serve as a starting point for including the pivot
  and splitting techniques from Maponi and Slaggel without the full
  complexity of the MaponiA3 algorithm
