Renames the crate from `concrete_compiler_rust` to
`concrete-compiler`.
- The `_rust` is removed as its redundant, the crate is a rust project.
- The `_` are replaced with `-` as its the naming scheme for our other
crates
- tinfo is a part of the ncurses project.
- tinfo does not seem easily installable stand alone
(no brew install tinfo, no dnf install tinfo-devel, etc)
but installing ncurses is possible and generally makes tinfo
'findable'
- on macos (M1 mac) it seems that even with ncurses installed
tinfo is not found, but linking to ncurses fixes the problem
we want to wrap CStructs in RustStructs to own them, and free memeory
when they are no longer used. Users won't have to deal with the direct
binded CAPI, but the new wrappers
This adds a new option `--unroll-loops-with-sdfg-convertible-ops`,
which causes loops containing SDFG-convertible operations to be fully
unrolled upon the extraction of SDFG-operations using the
`--emit-sdfg-ops` switch. This avoids constant roundtrips between an
SDFG-capable accelerator and the host during execution of a loop.
The option is limited to `scf.for` loops with static bounds and a
static step size. Since full unrolling of loops with large bounds
results in a large number of operations, the option is disabled by
default.
This adds a new pass `ExtractSDGOps`, which scans a function for
operations that implement `SDFGConvertibleOpInterface`, replaces them
with SDFG processes and constructs an SDFG graph around the processes.
Initialization and teardown of the SDFG graph are embedded into the
function and take place at the beginning of the function and before
the function's terminator, respectively.
The pass can be invoked using concretecompiler by specifying the new
compilation option `--emit-sdfg-ops` or programmatically on a
`CompilerEngine` using the new compilation option `extractSDFGOps`.
This adds a new operation interface `SDFGConvertibleOpInterface` that
allows an operation to specify how it is converted to an SDFG
process. The interface consists of a single method `convert` that
receives as the arguments the DFG created using `SDFG.init`, a set of
SDFG input streams corresponding to the operands and a set of output
streams for results. The order of the input and output streams
corresponds to the order of the operands and output values,
respectively.
This adds a new dialect called "SDFG" for data flow graphs. An SDFG
data flow graph is composed of a set of processes, connected through
data streams. Special streams allow for data to be injected into and
to be retrieved from the data flow graph.
The dialect is intended to be lowered to API calls that allow for
offloading of the graph on hardware accelerators.
