Current OpenIMPACT Status and Software Releases

 Current Developments
The first OpenIMPACT beta is now available.

To build the compiler, download both the source tarball and the appropriate front end binary (openimpact-fe-). Unpack both tarballs to the same directory. OpenIMPACT uses a GNU configure script to set up the Makefiles. Installation instructions are in doc/INSTALL. Please contact OpenImpact-Support@gelato.uiuc.edu with any bug reports or other issues.

(Update 3/2/07, 13:40)
OpenIMPACT front end 1.0rc4.1 released. This fixes a bug where casts on pointer constants may not be inserted into Pcode. These packages will unpack to a directory named openimpact-1.0rc4.1. After unpacking the front end, copy the files within the openimpact-1.0rc4.1 directory to your openimpact-1.0rc4 directory containing the rest of the OpenIMPACT source code.

 Recompiled Software / Performance Numbers
  • We want to make the OpenIMPACT technology available to industry and research groups by providing binaries of common open source applications and libraries. They have been carefully built to achieve the best performance. Feel free to test them and send us your feedback.
     
  • We also provide the files that are needed to run OpenIMPACT binaries compiled using control speculation. These are the highest performance binaries that OpenIMPACT can produce, but require a specially patched kernel to work properly.
     
  • Currently we are also trying to find more researchers who regularly use the MILC suite on IA-64 Linux, as we have produced high-performance binaries but have found few testers or applications for them.
     
  • If you want to follow or contribute to any open issue, a  bug tracking system will be soon available.
