Version 2024.11, Fri Nov 15, 2024

The OmpSs-2 2024.11 release adds support for Coroutines through the NODES runtime and the nOS-V tasking library and introduces several new features in nOS-V which include support for a task suspension API, support for RISC-V, a Topology API, and a Memory Pressure API, among others. This release also introduces support for the breakdown model through ovni and nOS-V.

Nanos6

  • Add compatibility with ALPI version 1.1 by implementing various functions from the tasking interface

nOS-V

  • Introduce support for breakdown model implementation, supported through the use of ovniemu -b
  • Refactor shutdown mechanism, using a coordinated approach to prevent contention during runtime shutdown
  • Introduce a Memory Pressure API, to query the current occupancy of the nOS-V shared memory segment
  • Allow re-initialization of nOS-V, permitting the call to nosv_init() after nosv_shutdown()
  • Enable turbo setting by default, and add correctness checking to detect changes to FPU flags from outside of nOS-V
  • Add support for coroutines and similar constructs through the nosv_suspend() API.
  • Add support for RISC-V
  • Introduce a Topology API, which allows the configuration of system topology through the nosv.toml file
  • Allow submitting tasks as NOSV_SUBMIT_IMMEDIATE from a task's run callback
  • Introduce nosv_cond_t and related calls, as a replacement for pthread condition variables
  • Other miscellaneous fixes and improvements

NODES

  • Introduce support for Coroutines
  • Fix immediate successor logic from within busy threads
  • Fix wrong header include order in the build system affecting NODES' installation
  • Other minor bug fixes and code improvements

LLVM/OpenMP (libompv)

  • Support other LLVM/Intel compiler generated code in libompv (tracing) by setting OMP_ENABLE_COMPAT=1
  • Other bug fixes and improvements

LLVM/Clang

  • Miscellaneous bug fixes and improvements

Ovni

  • Add breakdown model for nOS-V
  • New mark API ovni_mark_*() to emit user-defined events
  • New API to manage stream metadata ovni_attr_*()
  • Update trace format to version 3 (to support independent streams)

Task-Aware Libraries

  • Introduce TAMPI-OPT, an update for the Task-Aware MPI (TAMPI) library which implements several optimizations
