Context-Aware Software Builds, Karthik Ravi Shankar

Defensive Publications Series

Software libraries are of the static or dynamic variety. In a static library, code from the library is integrated into the executable at compile time. The resulting executable is relatively large but runs fast and in a stand-alone manner. In a dynamic library, code from the library is linked to the executable at run-time. The executable is smaller, and due to the sharing of dynamic libraries across processes, has less memory overhead. However, running the executable is contingent on the presence of the dynamic library in the machine that it runs on. Linking a library at run-time can also cause …

Machine-Learning-Assisted Scheduler For Filesystem Input And Output, Mark Schott

Defensive Publications Series

Traditional computing systems use simple, fast-to-compute heuristics to inform various decisions, such as allocating fractions of input/output bandwidth when switching among various tasks. Although fast and simple to execute, heuristics alone fail to account for the context of the computing system and the system’s behavior as a whole and cannot make a more-optimal decision that accounts for hardware components, energy resources, or the environment in which the computing device operates. A machine-learning-assisted or neural-network-based scheduler can make inferences or predictions based on the system information, conditions, and dynamics and make a more-optimal decision in allocating system resources during input and …

Programmable Test Pattern Generator And Controller, Sandeep Bhatia

Defensive Publications Series

Memories are typically tested using preset test patterns that exercise the memory core. In the case of embedded memories, e.g., where memory is integrated within an application-specific integrated circuit (ASIC), conventional testing is not effective in uncovering defects in the memory-ASIC interface. Stress conditions, e.g., excessive bus activity, saturated interface bandwidth, power surges, noise, etc., that arise in operation are not reproduced adequately in the test phase. Memory defects that manifest under specific conditions, e.g., after many cycles of memory access, under certain data/address sequences, when neighboring memory cells hold particular values, etc., are often not uncovered.

This disclosure describes …

Data Transfer To Non-Volatile Memory (Or Persistent Memory) During Input Power Loss, Rama Prasad Atluri, Mark A. Lawrence, Daniel Humphrey

Defensive Publications Series

In a critical server losing its input voltage/power, the server goes down after 10/20ms of hold-up time. In these hold-up time the data need to be transferred from volatile memory to non-volatile memory (NVDIMM). For years this process is being done successfully, by transferring the data during this 10/20ms hold-up time. However, this process is having the disadvantage of the server going down for each and every event of input power loss using NVDIMMs platforms.

To overcome this disadvantage, a new method or technique is proposed in this publication/disclosure (Fig 1). The proposed technique utilizes the signal (called bulk voltage). …
