7594e15576 Improved memory allocation on the GPU. 2022-10-10 11:01:53 +02:00
Francois Coppens
bba5cf5f2c Improved version. 
- All static arrays replaced by dynamic ones
- All overhead induced by checking before and after running of the kernels replaced as much as possible with calls to MKL/DGEMMs.
- Solved bugs due to dimension mismatches.

Overhead time is dramatically reduced because no more calls to naive 'matmul'.

4e7a334b78 - LAPACKE_dgetrf/ri replaced with cusolverDnDgetrf/rs. 
- Solved sign bug in computation of determinant.

Most code is now executed on the device. Some openMP pragmas can be consolidated.

7e42a000c4 Update integration of vfc_probes 
vfc_probes used to be built along the code in the previous versions.
This has been removed so that the verison used is the one provided
system wide by Verificarlo. Moreover, vfc_test_h5.cpp has been update to
reflect the name changes of vfc_probes functions.

74bb333de1 - Passing break-down threshold as a function argument 
- Renaming kernels to correspond with the ones in QMCkl
- In the qmckl-version of the test program, chaning the way integer data is read from the HDF5 file.

6ce2055e59 * Removed dependency on qmckl_threshhold() and the accompanying preprocessor definition. 
The break-down threshold now has to be passed explicitly as a function argument.
* Break-down threshold must now be passed on the command line together with the residual threshold.

Residual = wb3 14 9.92936e-07 1.90518e-11
    ok -- cycle 14

    Residual = qmckl_wb3 14 9.92936e-07 1.90518e-11

e188871df4 Fixed unsigned int/uint64_t/H5::PredType::STD_U32LE problem in qmckl_test_h5.cpp that caused the segmentation faults due to array indices running out of bounds. Naive Sherman-Morrison and Woodbury 2x2 kernels are working correctly from QMCkl with good accuracy. 
Residual = sm1 23 2.665e-07 5.85161e-13
ok -- cycle 23
Residual = qmckl_sm1 23 2.665e-07 5.85161e-13
