Shared numerics and measurement primitives:
MathUtils (statistics, percentiles, Cholesky,
matrix solve/inverse, normal distribution),
LatencyRecorder (zero-allocation log-linear
nanosecond histogram) and HiccupMonitor
(jHiccup-style platform stall attribution — GC/safepoint/scheduler pauses
versus code latency).-
ClassesClassDescriptionjHiccup-style platform stall monitor: a daemon thread repeatedly parks for a fixed resolution and records how much longer than requested each park took.Zero-allocation nanosecond latency histogram (HdrHistogram-style log-linear buckets: 16 sub-buckets per power of two, ~6% worst-case quantile error).Numerical primitives shared across the library.
