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.
add install target in Makefile to copy necessary libs, bins, and
includes to an installation directory. Use this install target to
package deps into a tarball with new installation instructions.
When this type of benchmarks is triggered, only the tests that
benefits from GPU acceleration are run on a specific AWS EC2
instance. Note that this instance (p3.2xlarge) is not a bare metal
one, so performance may variate due to hypervisor controlling the
machine.
Now compiler builds on AWS can be requested in Pull Request comment
using '@slab-ci <build_command>'. This sets up environment to able
to trigger both CPU and GPU builds on AWS EC2.
C struct now contains an additonal char* pointer, which can be either
NULL in case there is no error, or a buffer containing the error
message. It's the responsability of destructor function to free that
memory.
CAPI covering a wider API of the Support library.
Better error handling. Could also be improved by returning an error
message back from C to rust (left TODO).
