Cashmere: Building Cashmere Applications
Cashmere applications must be compiled with a special compiler,
csm_cc, that duplicates all writes to shared memory. You must link
your application with either the regular cashmere library (libcsm.a)
or the debug version of the cashmere library (libcsmd.a). Your source
code should include the csm.h header file. Cashmere applications can
be written in either C or C++.
The following command will compile and link the Cashmere application
``ufft'' with the regular Cashmere library.
Csm_cc will use the GNU C/C++ compiler with an additional
write-duplication pass to compile and link the application. It links
the application with the libraries libimc.a and libmach.a in addition
libraries linked by gcc. To link with the debug version of the
cashmere library, use the -lcsmd command line option.
csm_cc -o ufft ufft.cpp -lcsm
If you want to compile without automatic write duplications, you must
include the /u/cashmere/include directory in preprocessor pass
and the /u/cashmere/lib directory in the link pass. You must also
manually link the three libraries: libcsm.a, libimc.a and
libmach.a. For example:
In addition, you must manually duplicate all writes to shared memory.
There Cashmere library exports a function ``csm_duplicate_writes''
that will duplicate write a block of memory.
