* Use a single printf per line (reduce chances of lines being cut in logs)
* team_comm can be an int or a pointer depending on MPI impl.
Received is confusing (since we are on the origin), use submitted
instead
* Print arguments to calls when using DEBUG

accordingly
- add dlmalloc get_used/get_avail, and have all strats allocators also have a get_used
- Rework memallocator unit tests: bin size is per strat, alignment is verified in singleheap

* use correct MPI initialization method
rocSHMEM requires that the MPI library is initialized using
THREAD_MULTIPLE support. Lets use that function therefore in our
examples.
* Update examples/rocshmem_init_attr_test.cc

* unify handling of env variables
create a class containing all (most?) environment variables used by rocshmem and an object that is instatiated
before library_init, since some of the environment variables need to be
set before we start the bootstraping process.
This allows us to remove two files from the bootstrap directory.
* replace INFO and TRACE macros with DPRINTF
to be more consistent with the rest of the rocSHMEM code
Show and log what the functional test driver is running
* Log errors in the log file
* list all failed tests at the end
* pretty colors :x
* Print stderr when the test has failed

* add code for bootstrapping
the bootstrapping code has been extracted from the MSCCLPP library,
which in parts is based on the code from NVIDIA. The code has been
modified to match the specific requirements of the rocSHMEM library.
* add code to use the new uniqueId bootstrapping
* adjust init_attr example
extend the rocshmem_init_attr example to use two disjoint groups
of processe, in order to trigger the new code path.
* add env variable for bootstrap timeout
* Update examples/rocshmem_init_attr_test.cc

* Update backend to use provided MPI communicator during library initialization, default to `MPI_COMM_WORLD`
* Update `rocshmem_my_pe` and `rocshmem_n_pes` host APIs
- Return values from backend if initialized; otherwise, fallback to MPI_Singleton.
* Remove unused forward_list
* Remove unused __read_clock function
* Replace wallClk code with hip function
* Remove unused unit test for ipc
* Remove slab heap
* Remove unused EBO spinlock
* Update the naming convention for collective APIs to ensure consistency across the interface.
* Move all collective API declarations to rocshmem_COLL.hpp
* The following APIs were updated as part of this change:
- `barrier`
- `barrier_all`
- `sync`
- `sync_all`
- `all_to_all`
- `broadcast`
- `fcollect`
- `all_reduce`
* Update header file generation code for collective APIs
* Add thread, wavefront, and workgroup-level `barrier` APIs in IPC and RO conduits; remove collectives on default context
- Implemented `barrier` APIs for thread, wavefront, and workgroup scopes
- Added support into both IPC and RO conduits
- Added functional tests to cover all `barrier` APIs
- Removed collective operations on default context
* Add thread, wavefront, and workgroup-level `sync` APIs in IPC and RO conduits.
- Implemented `sync` APIs for thread, wavefront, and workgroup scopes
- Added support into both IPC and RO conduits
- Added functional tests to cover all `sync` APIs
* update naming convention for context-based `barrier` APIs
* Fix deadlock in `rocshmem_ctx_wg_barrier_all` API in IPC conduit by adding per-context pSync buffers and context IDs
- Added separate pSync buffers for each device context
- Resolved deadlock when invoking barrier API (`rocshmem_ctx_wg_barrier_all`) concurrently from multiple contexts
* Update barrier_all functional tests for multi-context support
* Add thread, wavefront, and workgroup-level barrier_all APIs in IPC and RO conduits
- Implemented barrier_all APIs at thread, wavefront, and workgroup granularity
- Added support in both IPC and RO conduits
- Updated functional tests to cover all `barrier_all` APIs
* Add thread, wavefront, and workgroup-level sync_all APIs in IPC and RO conduits

- Added support into both IPC and RO conduits
- Added functional tests to cover all `sync_all` APIs
add the interfaces required to support rocshmem initialization
through the uniqueID mechanism. At the moment this still maps to
MPI initialization underneath the hood, but adding the functions might
simplify the porting of some applications to rocshmem. In addition, if
we need to transition away from MPI one day, this is also one step into
this direction.
This PR addresses two issues:
- reduce the number of contexts supported by the host-interface by
default to 1, we are not using those at the moment, and hence
we now create fewer MPI_Win at the startup
- introduces a micro-sleep in RO progress engine in case there are no
pending requests. This leads significant performance improvements
observed for inter-node communication with THor2 NICs.
* Allocate default context buffers and initialize queue for management
- Allocated the status flag, g return, and atomic return buffers for
the default context.
- Initialized `AtomicWFQueueProxy` instances to manage these buffers
efficiently for concurrent access.
* Update `BlockHandle` with default context buffers
* Add default context flag and update buffer retrieval functions
- Added a flag to distinguish the default context from other contexts.
- Modified return buffer functionns and `get_status_flag` function to accommodate
the default context
* Add default context primitive tests
- get, put, get_nbi, put_nbi, g, and p APIs.
* README: update documentation for RO support
update the README and the install_dependencies script to match the
requirements of the RO conduit.
* add CODEOWNERS file
* feat: Add AtomicWFQueue implementation
- Implemented wavefront-safe atomic FIFO queue ensuring first-come, first-serve order
- Added efficient synchronization using atomics
- Enhanced `dequeue` to wait until an element is available
* test: Add GTest for AtomicWFQueue
- Implemented unit tests for AtomicWFQueue using GoogleTest framework
- Added tests for `enqueue`, `dequeue`, and edge cases
- Ensured synchronization behavior and correctness under concurrent conditions
* Add assert in `enqueue` and update atomics
- Added an assert in the `enqueue` function to ensure it fails if the queue is full
* Update HIP version check for compatibility with versions >= 5.5
* Update memory allocator for context BlockHandle
- Replaced `HIPAllocator` with `HIPDefaultFinegrainedAllocator` for context `BlockHandle`.
* Update run commands for `rocshmem_g` and `rocshmem_p` functional tests
* add team-barrier implementation
add a team-barrier API and implementation in the IPC and RO conduit.
Clean up some of the logic in the RO Conduit to distinguish between
sync, sync_all, barrier, and barrier_all.
* add team_barrier_tests to functional tests
* RO/collectives: add linear algorithms using RPut/Rget
- make broadcast, alltoall and fcollect use a simple linear algorithm
using MPI_RPut/Rget, but without blocking in the execution
- remove the to_all interfaces, since they have been deprecated.
- remove the active-set interfaces, since they have been removed from
rocSHMEM
* avoid notification after barrier

* disable allocation of ata_buffer
a temporary buffer of 128MB was allocated when creating a team. In
previous versions of the code, that buffer was used by some collective
operations. This is not the case for now. Therefore, do not allocate the
buffer for now. I am not removing the element itself from teh
structure, since we might need it in future versions again.
