that now includes AMDGPU/HIP (compile and runtime updates), addresses
a few build issues that have popped up for the team during testing the
branch, and a few other odds-and-ends for cleanup and general
(small'ish) improvements.
Also includes:
-- the matmult example from Jaeyoung.
-- tweaks for cmake configuration of the experiments make file
infrastructure.
-- updates to make a closer match between the concepts and approach
used by both the cuda and hip targets/runtimes.
-- some tweaks / changes to the experiments.
- Fixed some code generation details related to rocm 6.1.2 (e.g.,
xnack behaviors changed as did ecc details -- basically becoming
part of the target binary vs. just an attribute). Apparnetly,
this makes binary images incompatible for a given gpu config.
Dropped in a kitsune (runtime) specific clang tidy file to keep it
from taken all of LLVM's core setttings.
A bit more cleanup and dropped a clang tidy config file to avoid
kitsune's runtime code style details from getting beat up by the
(toplevel) LLVM details.

[kitsune] Fix peculiar build-time behavior (lanl#53)
Because of the way the build system was set up, the targets and kitrt
would be "installed" at build time i.e. when running ninja/make as
opposed to ninja install/make install. This fixes that behavior and only
installs during ninja build/ninja install. When building, there will be
messages that suggest that those targets are actually being installed,
but they are being "installed" to a subdirectory within the build
directory.

dev/18.x linking error fixes (lanl#49)
clang/lib/Frontend has a call to a Tapir << operator, which means it has
to be linked against TapirOpts.
There's unguarded checks to Value::dump in HipABI, which is disabled for
release builds, so I've replaced them with LLVM_DEBUG calls. Note this
means you don't have that output before assertion failure for release
builds. Other options if that's important.

This is a squash of the commits below
First cut at some improvments to the numpy module.
Working on AMD/HIP fixes.
More woes and struggles with HIP builds in the 18.x refactoring/overhaul...
Oh the woes...
Fixing a bad merge.
More work on HIP integration into 18.x (bitcode search paths, build fixes, etc.).
Added matmult example from Jaeyoung.
WIP: Merge with LLVM 18.x
WIP: Merge with LLVM 18.x and HIP target fixes.
Oh the woes...
Fixing a bad merge.
More tweaks for a bit more stability with HIP enabled... Hopefully...
Basic experiments working for full suite of cuda+hip+opencilk.
Tweaks for cmake configure support in the experiments.
Missed new intrinsics file.
Fighting darwin specific woes.
Working on HIP support for 18.x...
- AMDGPU targets appear to require full feature strings now to be "appropriate"
(e.g., sramecc and xnack settings much match what is reported on command line
via rocminfo).
- squashed a cmake bug
Just minor clean up.
Updates to get runtime concepts aligned between hip and cuda (hip now
matching cuda design wrt stream creation).
Forgot to clean up some debugging details...
Some build tweaking for the experiments.
Missed a function signature update.
More benchmark/experiment tweaks.
runtime fixes for new stream model (hip now matching cuda)
more hip debugging...
more verbose support for hip runtime.
Fixing both runtime and code gen issues around hip stream changes.
debugging hip.
hip, hip, not hooray
Trying to get default threads per block value to work.
chasing performance issues.
working on more runtime debugging details.
Hopefully finished the initial/final hip support for 18.x...
- runtime updated to manage streams better (less overhead, matches cuda design)
- hipabi changed to reflect runtime interface changes. .
A few more tweaks to the hip runtime details.
- some code tweaks (deviation from the cuda code) due to missing hip functionality.
- enabled auto-launch parameter settings as the default (likely far from perfect but
better than hip provided hueristics on our examples/experiments.
shame, shame... missed a include <string> (some compilers happy,
others not so much...)
Squashed commit for hip support in dev/18.x. High-level summary:
- Fixed some code generation details related to rocm 6.1.2 (e.g.,
xnack behaviors changed as did ecc details -- basically becoming
part of the target binary vs. just an attribute). Apparnetly,
this makes binary images incompatible for a given gpu config.
- hip runtime closer in functionality and design to cuda. This
includes stream management (simplified) and launch parameter
determination based on simple multi-proc load determination.
Launch parameters still need a lot of work in concert with
what the compiler can provide.
- Some random bug fixes related to the details above.
- Tweaked some of the experiment details to match the new
kitsune build configuration for dev/18.x (llvm 18.x).
A bit more cleanup and dropped a clang tidy config file to avoid
kitsune's runtime from all LLVM code base restrictions.

Date: Fri Apr 12 10:35:38 2024 -0600
Disabled sync region optiizations (merging) due to issues with
multi-target code. While this could have performance implications in
some situations it is the only way we can avoid errors with mixed
threaded and GPU code. More bugs may be lurking.
Also includes updates to the runtime to deal with exposing GPU streams
to the calling stack frame for correctly handling continuations.
commit 35d70b993a1960e7c0399821f8f4ada89f1c25aa
Author: Patrick McCormick <651611+pmccormick@users.noreply.github.com>
Date: Thu Apr 4 16:30:40 2024 -0600
First attempt at fixing stream assignment from the runtime in a manner
that GPU streams can be better captured (e.g., opencilk continuations)
and GPU work can be launched and sync'ed by different host threads; this
addresses a bug (flawed assumption) in the runtime when it comes to
multi-target support and interoperability.

Author: Patrick McCormick <>
Date: Thu Mar 28 16:43:36 2024 -0600
fix bad context mistake -- relevant to multi-target thread-streams debugging...
this is a temporary workaround and not a correctness guarantee for behaving
well when opencilk and cuda targets are intermixed (it most certainly can also
have performance implications).

Merge remote-tracking branch 'origin/multi' into dev/16.x
commit acc3dfb187998cd8a53eca47c75340f9b22967ff
Author: Tarun Prabhu <tarun@lanl.gov>
Date: Thu May 25 10:35:36 2023 -0600
A squash of many commits covering a broad scope:
1. Address some bugs/details/features introduced with the 16.x merge.
- includes some minor tweaks for 16.x testing but this needs more work.
- clang's sema probably needs to be revisited and improved.
2. A significant overhaul of the runtime to support:
- binding of calling threads to unique (gpu) streams
- removal of a lot of crufty code that was no longer being used.
- simplified kernel launch options/interface
- occupancy-based launch parameters (can cause performance regressions)
- better environment variable support for tweaking behaviors and
more flexibility for experimentation, testing, and debugging.
3. In alignment with #2 portions of the transforms for CUDA and HIP have
been cleaned up and simplified (in particular kernel launch details are
much cleaner now).
4. Some bug fixes for attempts at post-processing code w/out parallel
constructs. New "experiment" introduced to catch this as a regression.
5. Some runtime building blocks for driving prefetch operations.
6. Some new experiments/test codes.
7. Fix for nested outlining -- assumed dead-code elimination pass cleanup
but fails with separate host and gpu code transformation modules. Had
to introduce dead-code removal prior to gpu module passes (otherwise, the
verifier pass fails).
8. Runtime entry points for numpy allocation entry points (e.g., calloc,
realloc, etc.). TODO: Potentially some room here for GPU-side operations to
improve performance.
9. Attribute support (e.g., target) for Kokkos 'statements'.
10. General code cleanup -- removing warnings, unused code, etc.
11. New support for launch parameter exploration within the experiments code
base.
12. Some work on -ffast-math crashes and issues. TODO: This code needs to be
further developed (expanded support for double-precision, additional entry
points, etc.). There are also some issues here in what is specified on
the command line can impact code from the host side but does not have a
similar match on the GPU code of code transformation. TODO: ABI and
other issues need to further explored.
13. Multiple target support within a code base is supported (e.g., run opencilk
cpu threads and cuda-targeted forall loops).
14. Fixes around mutli-thread entry points within the runtime components.
15. Testing and feature support for H100; sync'ing CUDA and PTX version info, etc.

Author: Patrick McCormick <>
Date: Tue Dec 5 08:52:30 2023 -0700
Working on some issues surrounding --ffast-math:
1. ABI conflicts between the host stage and our module offload
generation (e.g., host side passes generate vectorized code that is
not supported on GPU backend(s).
2. Host architecture-centric tweaks occur before our GPU transform.
That leads to addressing host architecture specific details as
part of the transform (e.g., aarch64 and x86_64 will generate
different calls vs. sticking with llvm intrinsics).
A combo of ABI issues and/or the fact we're too late in the pass pipeline
to address this with the current design means more work lies ahead...

More work to setup the tests for better HIP and CUDA target flexiblity;
including some reduced complexity the command line arg details in the
makefile(s) (e.g., strip mining flags for GPU targets moved into the
config files vs. being necessary in the makefile setup).
Added better (correct) AMDGPU target attribute selection based on
multiple target options (prior version was too hard-coded for gfx90a).

Some hacking for trying to debug AMD HIP code gen/runtime issues. A few new environment variables to
make chasing (our tails) easier...
- KITRT_THREADS_PER_BLOCK=1024 (default 256)
- KITRT_MAX_NUM_PREFETCH_STREAMS=2 (default 4: size of round-robin stream queue for concurrent prefetch calls)
- KITRT_DEVICE_ID=5 (default 0: change the default GPU selection)
- KITRT_MIN_WARPS_PER_EXEC_UNIT=1 (default 1: reducing resource usage per warp -- impacts register allocation, etc.)
The prefetch stream queue is enabled via the command line with "-mllvm -hipabi-streams".

Bug fix for -ftapir gpu targets when no parallel loops are encountered

This includes all the work by Pat McCormick <pat@lanl.gov> to add support for
AMDGPU.s This also includes an overhaul of the kitsune/experiments directory

There is still some work to be done - for instance, getting rid of the legacy
pass manager for everything except backend code generation, but this should
be in a functional state for now.

Fix experiments to account for shuffling of headers in the kitsune
runtime organization (still not happy with it but at least things
appear to work now).
Also fixed a commented out stream sync call in the runtime from the
stack overflow debug-a-thon...

Restructure runtime source to provide one library (makes life easier in
the compiler/clang code base too). Using NVIDIA's HPC SDK seems to trip
up some aspects of CMake's cuda package (set CUDAToolkit_ROOT to address
this).
Continued work on trying to track down GeForce crashes.
Some new code for tapir target attributes.

Date: Thu Aug 4 16:32:05 2022 -0600
Updates for some issues related to performance and new tests/experiments
for digging futher into some UVM performance impacts.
CUDA target transform changes:
1. Removed vectorization pass.
2. Ran additional inlining pass post PTX-prep transformations (as well as
supporting passes). More experiments needed here.
3. Fixed some issues with ordering of PTX-level function renaming and some
general code cleanup.
Runtime:
1. Poking at some additional logic to support "auto" prefetch.
2. Playing with some runtime hints to the page system; so far they seem
to have minimal (no?) impact.
3. Some general code cleanup.

Date: Tue Jul 26 08:44:46 2022 -0600
Fixes for tranforming function calls into libdevice names (bug when we had
multiple occurences of the same function across kernels). Also fixed a issue
where we were not transforming cloned decls for functions that map into the
cuda's libdevice library (module).
Code still needs some cleanup, better checking, and some more test drives.
Pushing this up as it is likely the bugs above will trip up more complex use
cases.

forall and kokkos versions of the Rodinia srad benchmark.
TODO: The forall and serial version of the code have similar final
results but Kokkos looks to be much futher off. Could be a
missed sync between the host-device dual view data but have
not tracked it down yet...
commit 49d6f38c167db5a66c58c06862d999137a99bb38
Author: Patrick McCormick <651611+pmccormick@users.noreply.github.com>
Date: Tue Apr 26 16:40:13 2022 -0600
Overhaul of the CudaABI tranform and portions of the Tapir
infrastructure. This includes some bug fixes as well as an approach
for post-processing the transformed code at the module level.
Handles const global variables (creates device side and issues
host-to-device memcpy of values -- something you can't do in
CUDA/Kokkos without using __managed__). There are restrictions on
this capability but checks are not yet in place to enforce those
restrictions.
Performance appears to be on target w/ previous version (i.e., up to
2-4x faster than Kokkos at best and on par with both CUDA and Kokkos
for simpler code bases). This currently relies on UVM memory
allocation and prefetch call code generation prior to kernel launches
(default behavior now).

This is a squash of several updates for the CudaABI transform and the
supporting kitsune Cuda runtime components. There are several new
features and capabilities for driving the transform via the command
line (-mllvm -cuabi...), support that should allow for support across
modules (compilation units), code generation of prefetch via
coordination between the compiler and runtime, various bug fixes, and
a few experiments that include hand-coded and tests as the features of
the transform advanced.
TODO: More work needs to be done to update the docs and such to
capture the full scope of the feature set but things seem stable
enough to unleash the next phase of testing across the team.

A few last-minute fixes before release:
1. -fkokkos mode forces -fno-exceptions to avoid code gen issues
around parallelism code gen and internal exception mechanisms.
2. following #1, added a patch to #ifdef out exceptions (try and
catch blocks) in Kokkos memory spaces.
3. fixed a bug in the realm ABI that only showed up for some
examples -- would crash the compiler via an assertion on the
types of a binary operator.
4. tweaked some of the kokkos examples to actually behave like a
good kokkos program should...

Some clean up to remove the cudakit target (towards unification across
the toolchain between tapir, kitsune, opencilk, etc.).
New cuba abi runtime target code to simplify code gen -- needs to
merge design ideas with George's current multi-architecture approach.

Yet another attempt to address build issues that are clearly a race condition
on build order that can vary between parallel job size as well as platform (e.g.,
faster systems are builds are more likely to fail). This hopefully stems from
a dependency issue but could also be impacted by bugs in either ninja or cmake.
Would suggest updating to use the latest ninja (1.10.2) and cmake -- both were
used on the final pass of testing before this commit.

More work to sort through adding the Realm ABI target into the build
system w/ realm as a FetchContent component. This means some dependency
and target work within cmake, some ordering details about where the
FetchContent occurs, and also some fixes to the code base that were lost
for realm support (e.g., missing switch entries).
There is some point where the overall cmake config becomes more difficult
to reason about than the llvm+clang+... source code. ;-)
A few additional fixes for the config file (.cfg) settings and supporting
cmake pieces. The default config files are autogenerated to handle both
the in-tree and install use cases. It is probably worth tailoring for
your own use cases at some point but adding them to your user directory.
TODO: there is currently a "collision" between the use of a cmake option
and the ABI libraries to build within kitsune. At present you will have
both enable and add the abi library to the configuration (see the cache
file under kitsune/cmake/caches/kitsune-dev.cmake).

Tweaks to address some issues with the -fkokkos option and the addition of
command line arguments to align with the full toolchain build. One issue
is that link libraries that appe…
