***************************** DIRECTORY STRUCTURE ******************************
NOTE: This graphic is *way* out of date (for instance, the pthreads directory is
not shown), but still gives the general idea, so I leave it in.
The directory structure of ATLAS can be summarized by the following graphic:
---------------------------------------------------------
| | | | | |
bin interfaces tune lib include src
| | |
| ----------------------- ----------------------------
| | | | | | |
| | blas auxil testing | lapack
| | | |
| | ------------------------------ blas
|sysinfo | | | | |
| gemm gemv ger level3 |
| |
---------------------- -----------------------------------
| | | | | | | |
blas lapack level1 level2 level3 gemm ger gemv
| |
--------- ---------
| | | |
src testing src testing
This directory structure is duplicated in the SRCdir and BLDdir directories,
with SRCdir containing the original source files (obtained from the ATLAS
tarfile) and BLDdir (created by the configure step) containing the generated
libraries, headers, objects, and executables.
A summary of each of the main directories is given below:
** interfaces : The official C and Fortran77 interfaces that ATLAS supplies.
Users needing to examine the API can go to the appropriate
src subdirectory. If it exists, the official API tester is
available in the appropriate testing subdirectory.
** bin : ATLAS's user-runnable testers & timers are built here
** lib : Libraries are compiled by default into this directory
** tune : The code generators and timing programs that allow ATLAS to
tune itself to specific architectures are here
** include : All of atlas's include files. Architecture-dependent include
files appear in the appropriate <arch> subdirectory.
** src : Stores the routines supported by atlas; once optimal cases have
been found, this is also where the generated code is stored.
In addition to those shown above, the user should be aware of the directories:
ATLAS/doc : ATLAS documentation
BLDdir/bin/INSTALL_LOG : Log of the build step for each architecture
