nOS-V 2.2.0 (OmpSs-2 2024.05)

Version 2.2.0, Wed May 15, 2024

This version corresponds to the OmpSs-2 2024.05 release. It contains batch task submission, a new barrier and mutex API and ovni instrumentation for parallel tasks.

Changelog

• Implement a batch submission API, which can accumulate tasks to submit them in batch once a certain threshold has been reached.
• Add nosv_mutex_t and nosv_barrier_t as nOS-V aware alternatives to their pthread counterparts, improving interoperability.
• Add instrumentation points for the nosv_attach and nosv_detach calls.
• Add instrumentation for parallel tasks.
• Activate the turbo.enabled configuration option by default, which enables flush-to-zero in x86-64 and aarch64.
• Perform safety checks when the turbo.enabled configuration option is set to verify FPU flags are not modified by external libraries.
• Split instrumentation events for the scheduler to allow them to be more granularly controlled.
• Allow nOS-V programs to call fork() without leaving the forked process in an incoherent state.
• Various refactors and bugfixes.
