* Add environment variable configuration infrastructure
- Namespace rocshmem::envvar
- Track all config env vars in per-category lists
- Remove duplicates from list of allowed env var types
- Reject negative inputs for unsigned integer types
- Accept empty strings for std::string
- Print error source location using C++20 std::source_location
- Unit tests
* Port environment variables
- ROCSHMEM_UNIQUEID_WITH_MPI
- ROCSHMEM_RO_DISABLE_IPC
- ROCSHMEM_BOOTSTRAP_TIMEOUT
- ROCSHMEM_BOOTSTRAP_HOSTID
- ROCSHMEM_BOOTSTRAP_SOCKET_IFNAME
- ROCSHMEM_RO_PROGRESS_DELAY
- ROCSHMEM_BOOTSTRAP_SOCKET_FAMILY
- ROCSHMEM_MAX_NUM_CONTEXTS
+ Merge the independent per-backend copies into a single variable
that is used by all three backends (IPC, RO, GDA).
+ Set default to 32 (for GDA); prior default for IPC and RO was 1024.
- ROCSHMEM_MAX_NUM_HOST_CONTEXTS
- ROCSHMEM_MAX_WF_BUFFERS
- ROCSHMEM_SQ_SIZE
- ROCSHMEM_RO_NET_CPU_QUEUE
+ Renamed from RO_NET_CPU_QUEUE
+ Change env var input type to bool, default to false
+ Invert code logic: setting RO_NET_CPU_QUEUE to anything
would /disable/ a variable gpu_queue, which defaulted to true.
Variable is now named config::ro::net_cpu_queue,
with all prior checks for gpu_queue inverted.
- ROCSHMEM_USE_IB_HCA
- ROCSHMEM_HEAP_SIZE
+ Defaults to 1L << 30 i.e. 1 GiB,
from default heap size in memory/heap_memory.hpp.
- ROCSHMEM_MAX_NUM_TEAMS
+ Unlike other env vars, this can be referenced from devices.
+ Function currently narrows from size_t to int: uses need to be audited
for safety and correctness in using size_t directly.
- ROCSHMEM_GDA_ALTERNATE_QP_PORTS
* New env var ROCSHMEM_DEBUG
- Debug levels:
+ NONE
+ VERSION
+ WARN
+ INFO
+ TRACE
- Currently unused - will be added later
- Mirrors RCCL debug control
* Remove rocshmem::rocshmem_env_config
* Change interface for GetClosestNicToGpu
to accept const char** instead of char**:
the pointed-to string does not need to be modified
- Files were not audited for inclusion of util.hpp only for env vars
