2e4b8a8fc4 [CK_TILE] Remove Old CK Tile Stream-K Artifacts (#3202)
* Remove old CK Tile Stream-K implementation

The original CK Stream-K implementation was based on old CK's Stream-K
block to C tile map. However, this implementation did not align with the
original Stream-K paper. Thus, we implemented a new tile partitioner and
associated Stream-K kernel, which was placed in the reboot namespace.

Now that the new Stream-K implementation is ready, this change removes
all artifacts of the old implementation. Specifically, the following
changes were made:
- Removes old Stream-K tile partitioner from CK Tile
- Removes the reboot namespace such that the new implementation resides
  in the ck_tile namespace only.
- Adds tests for bf8 and fp8 using the new implementation
- Removes tests for the old implementation
- Remove the v2 suffix from the new CK Tile Tile Partitioner
derived classes.
- Updates Stream-K Kernel ops file to use /** commenting style.

* Remove v2 from tile partitioner validation function names

054fdb765c [CK_TILE] Stream-K operator() Reboot (#3064)
* Persistent Stream-K Kernel Implementation

This change implements an operator() function in the
reboot::StreamKKernel class that is enabled when the Persistent flag is
set to true. In this case, the data-parallel portion and the Stream-K
portion of the kernel are fully persistent.

The changes were made in the reboot namespace. A future PR will remove
the old Stream-K kernel class and remove the reboot namespace.

* Unit Tests for Persistent Stream-K Kernel

This change contains the inital test suite for the Persitent Stream-K
Kernel. The files contain "reboot" in the name; a future PR will remove
tests for the old Stream-K Kernel and remove the "reboot" naming.

A future commit will add tests for the non-persistent kernel.

Also added estimate_num_wgs_per_tile to the StreamKTilePartitionerBase
class. This allows us to estimate the number of accumulations done per
macro tile in C to use during validation when computing relative and
absolute tolerance.

* Adding implementation for the Non-Persistent Stream-K kernel

This code is adding the operator() function for the Non-Persistent Stream-K
kernel. Persistency of the kernel is determined through a template argument.
The Non-Persistent kernel will allocate additional workgroups for the data
parallel section, leading to a different structure for processing the data
parallel and Stream-K sections.

There has been an addition to the TilePartitioner to get access to the whether
Persistent has been set to true or false in the StreamKKernel.

* Adding in the tests for the Non-Persistent Stream-K kernel

* Refactor Stream-K Reboot Unit Tests

This commit makes the following changes:
- Update test cases to determine M, N, and K based on the number of CUs.
  This ensures that each test case is one of Edge Case, SK Only, DP
Only, or DP + 2 Tile SK regardless of the architecture.
- Since the DP + 2 Tile SK test case takes long to run, this change
  moves this case into a separate .inc file and labels it as an extended
test.
- Since the extended test takes > 30 seconds to run, this test is added
  to the list of regression tests.

* Fix spelling errors in comments for test cases

* Changes based on review

Removed const volatile for typenames
Set up alias for is_tuple_t
Naming changes for clarity: GemmCommon -> BaseGemm
Moved std::enable_if_t out of template parameters and changed to a return type for operator()
Added constructor for StreamKKernelArgs to clarify UniversalGemm inheritance

f5708882a3 Streamk functional tests (#2974)
* Add initial fp16_mem_128x128x32_2x2x1_32x32x16_NonPersistent test suite

* Account for stride when computing K offsets for A and B tensor

This change ensures that the correct stride is used when computing the K
offsets into the A and B tensors in the Stream-K Kernel's operator()
function. This ensures that the kernel executes correct regardless of
whether A and B are row or column major.

* Move helper code to test_gemm_streamk_util.hpp

* Separate tests into smoke/regression/extended. Add bf16 datatype

* Run clang-format

* Refactor combinatorial macro expansion and naming

* Adjust the initialization values to account for better tolerance on bf16

* Correct BF16 datatypes in comments

* Move the extended tests under the REGRESSION_TESTS label

* Apply suggestions from code review
