Changelog¶
v4.0.x¶
| Release: | v4.0.0 |
|---|---|
| Date: | 5 January 2016 |
This release is a major overhaul of the code with the aim of making it more portable and reliable.
- Features
- Compatible with Intel Fortran compilers. The code may work with other compilers too, but only Intel and GNU are tested currently.
- Incompatibilities: This release is not compatible with version 3 or below.
- Removed the rpe_shadow derived type.
- Removed abstract base class rpe_type, the only user type is now rpe_var.
- Removed getter and setter methods, the value of an rpe_var instance is now accessed directly using the %val attribute.
v3.1.x¶
| Release: | v3.1.1 |
|---|---|
| Date: | 3 November 2015 |
- License code under the Apache 2.0 license.
| Release: | v3.1.0 |
|---|---|
| Date: | 16 October 2015 |
- Support for IEEE half-precision emulation via the RPE_IEEE_HALF module variable.
v3.0.x¶
| Release: | v3.0.1 |
|---|---|
| Date: | 4 November 2015 |
- License code under the Apache 2.0 license.
| Release: | v3.0.1 |
|---|---|
| Date: | 21 August 2015 |
- Features
- Support for different precision levels in different variables:
- You can set the %sbits attribute of any rpe_type instance to define the number of significand bits used by that variable.
- A set of unit tests is included to help us ensure the emulator core is robust.
- HTML documentation is included with the source (requires Sphinx to build).
- Support for different precision levels in different variables:
- Incompatibilities
- This version is incompatible with the v2.0.x series.
- The public API is now smaller, including only the required parts of the library.
- Module variables renamed: RPE_BITS -> RPE_DEFAULT_SBITS
- Reduction of precision subroutine renamed: reduce_precision -> apply_truncation
- Internal differences to support mixed precision may cause different results to previous versions.
v2.0.x¶
| Release: | 2.0.1 |
|---|---|
| Date: | 3 November 2015 |
- License code under the Apache 2.0 license.
| Release: | 2.0.0 |
|---|---|
| Date: | 29 July 2015 |
- Features
- Reduce precision on assignment:
- The precision of the value held within an rpe_type instance is reduced whenever a value is assigned, meaning an rpe_var instance cannot ever store a full precision value, and an rpe_shadow type will always store a reduced precision value when it has been assigned to directly (but one can of course assign a full precision value to the variable it is shadowing and have that value retained).
- Explicit calls to reduce_precision are no longer required in any overloaded operators or intrinsic routines, as the reduction of precision will be performed implicitly on assignment of the result.
- Reduce precision on assignment:
- Incompatibilities
- The change from explicit reduction of precision within overloaded operators and intrinsics will likely cause the emulator to return different results than the v1.0.x series.
v1.0.x¶
| Release: | v1.0.1 |
|---|---|
| Date: | 4 November 2015 |
- License code under the Apache 2.0 license.
| Release: | 1.0.0 |
|---|---|
| Date: | 28 July 2015 |
- Features
- Initial version used operationally for experiments.
