* use dlsym for MPI functions
to allow compiling without MPI support, convert the usage of MPI functions and symbols to be based on a dlopen/dlsym based mechanism. Turns out this cannot be done entirely vendor neutral, slightly different solutions might be required for Open MPI, MPICH and the new MPI ABI.
* checkpoint
more work to be done.
* checkpoint 2
* checkpoint 3
* checkpoint 4
examples compile and link correctly
* checkpoitn 5 (I think)
* Checkpoitn 6
* dyld-mpi: adapt GDA
* dyldmpi: tests that depend on MPI need to link with it themselves
* do not ../mpi_instance.h
* dyldmpi: make the symetricHeapTestFixture compile
* dyldmpi: Change cmakery, compiles and run gda w/o external MPI
* Make it also compile in external MPI mode
* dyldmpi: ipc unit tests compile but do not link
* dyldmpi: new approach, if external mpi required, link with mpi,
otherwise use ompi5 abi
* C-style comments in cmakelist..
* dyldmpi: examples: do not fail compiling if MPI not found at build time,
instead do not compile the MPI required examples
* more updates to CMake logic
* convert RO backend
and a few other cleanups
* update some unit tests
to work with the dlopen MPI environment correctly.

* Rework cmakery:
* detect rocm/hip/rocshmem better, make sure that ROCM_PATH and
ROCM_ROOT don't conflict and are taken by default
* add /opt/rocm as a fallback when nothing else found
* obtain hipcc in a sanitized way (ensure we use the same logic we
use to later find_package hip)
* factorize redundancies
* export GPU_TARGETS as part of the cmake target for librocshmem,
this helps with a clean error when an application tries to link
with the wrong offload-target flag (rather than a cryptic link error)
* phased out ROCSHMEM_HOME, in favor of rocshmem_ROOT (the cmake
blessed way)
* Remove references to ROCSHMEM_HOME, we prefer ROCSHMEM_ROOT
* Pick CMAKE_PREFIX_PATH method for consistent finding hip/rocm
* Undo this pr using LANGUAGE HIP, maybe later
* Use only rocmcmakebuildtools as recommended from 6.4 onward
* Add dlmalloc_strat allocator strategy
- Use mspace variant to ease encapsulation
- Make pow2bins and dlmalloc cmake selectable
* Add unit tester for dlmalloc, rework single_heap, pow2bins unit testers
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
* bugfix: dlmalloc exposed that the pingpong test would write past end of
allocation with -w 32
* iostream leakage/mixed usage of cerr and fprintf(stderr

* 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
* 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
add the initial outline of an ipc_context unit test. The current test
only invokes the ipc_context constructor, more tests will be added later
as the class is being populated.
Also, at the moment the unit test takes an ROBackend as an argument for
the constructor, not sure whether this will be the final solution.
