We’re excited to release Psyclone AIOS 2.1.1 — the most significant update to Psyclone since the 2.0 line. If you build real-time, distributed, publish/subscribe systems, this release makes Psyclone faster, more portable, and far easier to drive from the language you already use. Here’s what’s new since our last release (2.0.3). Psyclone now runs natively…
A rigorous single-node latency benchmark of Psyclone AIOS against NATS, ROS 2, iceoryx, eCAL and ZeroMQ – competitive default speed, the tightest tails measured, and the runtime-reconfiguration capabilities that set it apart.
Psyclone modules can now drive Amazon Bedrock and Google Gemini directly — bringing native, low-latency generative-AI inference into the real-time pub/sub fabric for building sub-second AI applications.
The SSL build now links OpenSSL 3 and ships a network_https unit test that performs a real TLS handshake and encrypted HTTP round-trips over loopback with a runtime-generated certificate — with a clear certificate-verification hardening path on the roadmap.
The psytest suite was rebuilt into a context-chained set of stages exercising context switching, time sync, guaranteed & best-effort messaging, signals, and catalog retrieval — each stage emitting a PASS/FAIL + perf line with a final aggregated verdict. It now reports full p50/p90/p95/p99/p99.9 tail-latency percentiles, not just averages.
A ground-up CMSDK test framework: one PASS/FAIL line per object, per-test process isolation with timeouts (a crash in one test can’t take down the suite), self-healing shared-memory cleanup, and timestamped performance JSON with %-deltas for automated regression detection. 33 tests, all passing.
The message-routing fast path was rebuilt: a 36KB per-message ring copy replaced with a circular write index, a per-message heap allocation and no-match leak removed from routing, header receive reduced to a single allocation, and six redundant syscalls stripped from every send/read cycle.
The same socket-mode and buffered-read optimisations lifted best-effort UDP messaging to 155,000 messages/second (up from ~107k) with latency down to about 6 microseconds (from 9.3us) — reinforcing Psyclone’s sub-10us real-time profile.
By keeping sockets non-blocking instead of flipping mode around every send (which cost four syscalls per message and raced the receive thread), TCP throughput more than doubled — from ~42k to ~90k msg/s — and per-message latency roughly halved, from 23.8us to ~11us.
Eliminated a class of silent data races: std::map::operator[] on read paths was inserting empty entries under a shared read lock (routing races + unbounded map growth). Fixed across SubscriptionEngine, Node, Monitoring, ServiceManager, InterSystemManager and the Catalogs, plus mutex-leak fixes and a NetworkChannel shutdown deadlock.
