a portion of the Panphasia field given an input descriptor.

Should be called early before significant memory is allocated. It

Has OpenMP - -DUSE_OPENMP in the makefile

The routines support both single and double precision

float or double.
|

|

The Panphasia coefficients can be single or double precision
|

|

MACROs PAN_REAL/PAN_COMPLEX define the Panphasia precision - either
|

float or double.
|

|
||||
|
||||
To change the Fourier precision edit PAN_FFTW3.h - by default
|
||||
single precision unless 'FOURIER_DOUBLE' is defined.
|
||||
|
||||
To change the Panphasia precision edit panphasia_functions.h and
|
||||
single precision unless 'PAN_DOUBLE_PRECISION' is defined.

----------------------------------------------------
|
||||
|
||||
14th April 2021
|
||||
|
||||
|
||||
|
||||
Found a bug in the OpenMP version. Different numbers
|
||||
of threads led to a subset of Fourier modes having
|
||||
different values. The precise differences changed
|
||||
each time the code was run.
|
||||
|
||||
Debugged by turning of OpenMP section by section.
|
||||
The section which uses the spherical bessel functions
|
||||
turned out to be responsible.
|
||||
|
||||
The faulty version collapsed for 4 loops over
|
||||
multipole,x,y,z. Changing this to a loop
|
||||
over multipoles, and collapsing 3 coordinate
|
||||
loops solved the problem.
|
||||
|
||||
The variable index1 of the return field
|
||||
does not depend on the multipole, while
|
||||
index2 does. Both index1 and index2 are
|
||||
private. This means the return array
|
||||
(index 1) is updated several times.
|
||||
Presumably as these updated occur
|
||||
in parallel with the 4 loop collapsed
|
||||
version the return array was being
|
||||
corrupted sometimes.
|
||||
|
||||
|
||||
15th April
|
||||
------------
|
||||
|
||||
This version supercedes version given to
|
||||
Oliver to add to MonofonIC clone.
|
||||
|
||||
Main difference is additional OpenMP
|
||||
statements and the ability to specify
|
||||
in the descriptor that modes less
|
||||
than of equal to some dimensionless
|
||||
integer wavenumber squared are set
|
||||
to the mean power.
|
||||
|
||||
Tested output on 1 core - with/without
|
||||
OpenMP. Not tested with more than
|
||||
1 MPI rank.
