|
|
----------------------
|
|
|
|
A minor update of ``ispc`` has been released with several stability improvements.
|
|
The released binaries are built with patched version of LLVM 3.3. Since this
|
|
release we also distribute 32 bit Linux binaries.

ispc 1.4.3 is Released
|
|
----------------------
|
|
|
|
A minor update of ``ispc`` has been released with several stability improvements.
|
|
All tests and examples now properly compile and execute on native targets on
|
|
Unix platforms (Linux and MacOS).
|
|
The released binaries are built with patched version of LLVM 3.3.
|
|
|
|
ispc 1.4.2 is Released
|
|
----------------------
|
|
|
|
A minor update of ``ispc`` has been released with stability fix for AVX2
|
|
(Haswell), fix for Win32 platform and performance improvements on Xeon Phi.
|
|
As usual, it's available on all supported platforms (Windows, Linux and MacOS).
|
|
This version supports LLVM 3.1, 3.2, 3.3 and 3.4, but now we are recommending
|
|
to avoid 3.1, as it's known to contain a number of stability problems and we are
|
|
planning to deprecate its support soon.
|
|
The released binaries are built with 3.3.
|
|
|
|
ispc 1.4.1 is Released

Paper on ispc To Appear in InPar 2012
|
|
-------------------------------------
|
|
|
|
A technical paper on ``ispc``, `ispc: A SPMD Compiler for High-Performance
|
|
CPU Programming`_, by Matt Pharr and William R. Mark, has been accepted to
|
|
the `InPar 2012`_ conference. This paper describes a number of the design
|
|
features and key characteristics of the ``ispc`` implementation.

ispc 1.1.4 is Released
|
|
----------------------
|
|
|
|
On February 4, 2012, the 1.1.4 release of ``ispc`` was posted; new features
|
|
include ``new`` and ``delete`` for dynamic memory allocation in ``ispc``
|
|
programs, "local" atomic operations in the standard library, and a new
|
|
scalar compilation target. See the `1.1.4 release notes`_ for details.

|
ispc 1.1.3 is Released
|
|
----------------------
|
|
|
|
With this release, the language now supports "switch" statements, with the same semantics and syntax as in C.
|
|
|
|
This release includes fixes for two important performance related issues:
|
|
the quality of code generated for "foreach" statements has been
|
|
substantially improved, and performance regression with code for "gathers"
|
|
that was introduced in v1.1.2 has been fixed in this release.
|
|
|
|
Thanks to Jean-Luc Duprat for a number of patches that improve support for
|
|
building on various platforms, and to Pierre-Antoine Lacaze for patches so
|
|
that ispc builds under MinGW.
