CRAFT: Configurable Runtime Analysis for Floating-point Tuning
Mike Lam, James Madison University
WARNING: THIS IS RESEARCH SOFTWARE!
Building and using this project currently requires some experience in systems development and tool infrastructure. This file includes some basic installation and compilation instructions, but they may require some manual modification on your specific platform. Contact the author if you encounter issues.
Currently this project only works on x86_64 Linux. The environment variable
PLATFORM needs to be set to "
DyninstAPI (Tested version: 9.1.0)
Dyninst must be compiled and accessible to the linker. The environment variable
DYNINST_ROOTshould point to the location it is installed.
XED2 Library (Tested version: from Pin 2.14-71313)
XED_KITvariable in the Makefile appropriately after you have downloaded Pin. There is no need to compile Pin or XED from source. Note that CRAFT does not use Pin directly, only XED.
Boost headers (Tested version: 1.53.0)
The default Boost headers on your system may work. If you get Boost-related compile errors, download the headers from the URL above and use the
LOCAL_INC_DIRSvariable in the Makefile to point the compiler to it (using
To build CRAFT, use the
make command in the root directory. You will need a
reasonably recent (4.x) version of gcc. The build has been tested with gcc
There is currently no installation routine. You will need to add the
folder created by the build process to
LD_LIBRARY_PATH. I recommend
writing a shell script to set
For replacement analysis to work, the current directory ("
.") also needs to be
LD_LIBRARY_PATH so that the runtime linker can find the rewritten shared
To test the build, execute the
./run_tests command in the testsuite folder.
To sanity-check a non-testsuite executable, try one of the following commands:
fpinst --cinst <binary> fpinst --dcancel <binary> fpinst --svinp double <binary>
To use the automatic search script, you will need Ruby 2.0 or later.
To build and use the GUI, you will need Java 1.6 or later.
