Abstract: Systems and methods for an eBPF general allocator for an eBPF program is provided. The method includes receiving, by a first eBPF program, a first entry based on an atomic operation. The first entry is from a number of entries in a free list that indicates available space in a buffer. The available space is indexed by the number of entries in the free list. The method further includes identifying, based on the first entry, a pointer to the buffer. The pointer is associated with an allocation of the available space in the buffer based on the first entry. The allocation of the available space is to the first eBPF program. The method further includes executing, by a processing device, the first eBPF program with exclusive access to the allocation of the available space in the buffer during an execution instance of the first eBPF program.

Abstract: A non-transitory computer readable storage medium has instructions executed by a processor to compute an x-axis axial position based upon a first host border measurement signal, a second host border measurement signal, first x-axis axial measurement signals and second x-axis axial measurement signals. A y-axis axial position is computed based upon the first host border measurement signal, the second host border measurement signal, first y-axis axial measurement signals and second y-axis axial measurement signals. A z-axis axial position is computed based upon the first host border measurement signal, the second host border measurement signal, first z-axis axial measurement signals and second z-axis axial measurement signals. The operation of a computer numerical control milling machine is coordinated based upon the x-axis axial position, the y-axis axial position and the z-axis axial position.
