PENF

PENF, Portability Environment for Fortran poor people

A KISS library for exploiting codes portability for modern (2003+) Fortran projects.

PENF is a pure Fortran (KISS) library for achieving portable codes for modern Fortran projects;
PENF provides many number-to-string and viceversa facilities;
PENF is Fortran 2003+ standard compliant;
PENF is a Free, Open Source Project.

What is PENF?

Fortran is the most popular programming language for scientific computing. With Fortran it is quite simple obtain fast code and manage large multidimensional array. Because Fortran permits the achievement of high performance it is also used on great range of different computer-architectures, and often on the fastest supercomputer in the world. Therefore Fortran programs must be portable: portability means that the code will give the same results on every different computer-architectures. One of the most important goal of the numeric code is to control the numeric error due to finite precision of numerical operations. Fortran uses the IEEE representations. Integers and reals (floating point) are represented with a finite precision. So when the code computes an operation it has a truncation error due to the truncation of the numerical finite representations. For numerical and more in general scientific applications this source of errors must be controlled. The programmer must know which is the precision associated to the code variables. Before the standard Fortran 90/95 there are not any way to select the precision of the numerical variables in a portable fashion.

Modern Fortran standards (2003+) have introduced better support for codes portability. With the possibility to specify a kind parameter for variables, the standard Fortran 90+ makes available useful functions to select the kind precision in a portable parametric way. Using these functions the programmer can accurately control the precision of its own variables in a portable manner.

PENF module provides an effective KISS library to achieve portability and concurrently it provides many tools to handles parametrized numbers.

Main features

The library provides portable kind-parameters and many useful procedures to deal with them:

integer and reals parameters for 1,2,4,8,16 bytes-like representations;
integer and real formats definitions for all parameters;
integer and real minimum maximum representable numbers;
number-to-string and string-to-number casting procedures;
endianism procedures checking.

Any feature request is welcome.

penf's Issues

Wrong name in API documentation

Just noticed that in your FORD project file (and thus the docs on your Github pages) you are still referring to this library as IR_Precision. Thought I'd let you know.

Smallest real representable difference

Hi,

I was using the parameter ZeroR8P for the comparison purpose of two real values. Lately, I updated source files and realized the change in the definition of the parameter. In the previous version of PENF, the definition was,

real(R8P), parameter :: ZeroR8P = nearest(1._R8P, 1._R8P) - nearest(1._R8P,-1._R8P)

and I was using the parameter to compare the reals as

if ( abs( a - b ) < ZeroR8P ) then

However, the latest version is defining the ZeroR8P as,

real(R8P), parameter :: ZeroR8P = 0._R8P

and the comparison fails. I wonder the reason behind this change. Was the previous version causing a bug?

add character kinds

Add parameter kinds for character variables, namely ASCII and UCS4 kinds.

bits string casting of reals

The casting of numbers (integer and real) to bits string is done by B format specifier. This is standard (2003) compliant only for integer, whereas for real this is an Intel Fortran extension! This is known bug that must be fixed in some way. The trick to use transfer function seems to not work correctly. The low-level bits functions must be used...

Backward compatibility

Dear @szaghi !

I use PENF in my own little project. I also use FLAP that is dependent on PENF. I use FoBiS to build project. Recently I decided to update submodules and found out that FLAP doesn't use modules from its dependent version of PENF. It uses modules from my submodule that has been recently updated.

Main problem is that R16P is now surrounded by _R16P macro and FLAP can't see that parameter any more.

My questions are: Why did you decide to surround R16P with a macro? What is the correct way to build project? Adding _R16P macro to the fobos file?

I am assuming that FLAP is not the only example. Most of your projects use PENF..
Thank you!

Customize separator in string conversion procedures

Hi @szaghi ,

in my fork I've added separator, an extra argument, to str_a_* procedures to allow clients to customize how to separate different elements of an array while converting to a string. It's not a great enhancement but i think it will be useful.

For example, I need this because FLAP set procedure needs strings for setting default values. While PENF returns array strings as "1,2,3,..", FLAP needs them in this way "1 2 3 ...".

storage_size vs bit_size

PENF/src/lib/penf_global_parameters_variables.F90

Line 150 in d471d5a

integer(I1P) :: BYR4P !< Number of bytes of kind=R4P real.

would storage_size (https://gcc.gnu.org/onlinedocs/gfortran/STORAGE_005fSIZE.html) be an alternative for bit_size? It also works for reals.
