Fraps Windows 10
Fraps windows 10 Continue I noticed a person in the myst-Uru community point out that FRAPS doesn't work on their Windows 10 machine. I'm on the verge of upgrading my main machine to 10. So what's going on? First, visit the FRAPS website. FRAPS is advertised for Windows until version 7. The newest version of 3.5.99 was released in February 2013... two or more years ago. (By number 11/24/2018 there are still no updates.) Are they going to update it for Windows 10? I can't find any information to reliably answer that question. I've seen some people commenting that the latest pace of updates several times a year stopped in February 2013. Requests that use the contact form in FRAPS have largely gone unanswered. A June 2015 video shows FRAPS working in Win10 on older hardware. Some search shows people have problems with FRAPS on Win10. There is some discussion of this issue in the FRAPS Windows 10 Thread issues on Microsoft forums. Update 11/2018: No new FRAPS updates, 5 years. Now I find FRAPS dead. Exploring ways to get FRAPS working on Win10... I don't find good fixes or solutions. Tom's Hardware Review and other technology sites have no answers. In this topic, one person says they received an email back from FRAPS people saying an update to Windows 10 is in the process. (I take it as a rumor.) This one doesn't exist. This is from the post in August 2015. The date of the letter was not included. -

Software-Based Undervolting Faults in AMD Zen Processors Fehler in AMD Zen Prozessoren Durch Software-Basierte Unterspannung
Software-based Undervolting Faults in AMD Zen Processors Fehler in AMD Zen Prozessoren durch Software-basierte Unterspannung Bachelorarbeit im Rahmen des Studiengangs IT-Sicherheit der Universität zu Lübeck vorgelegt von Anja Rabich ausgegeben und betreut von Prof. Dr. Thomas Eisenbarth mit Unterstützung von Luca Wilke Lübeck, den 31. August 2020 Abstract Dynamic Voltage and Frequency Scaling (DVFS) is a powerful performance enhance- ment method used by modern processors, allowing them to scale voltage or frequency as needed based on the power requirements of the CPU. This not only saves power, but also prevents processors from overheating. However, the continued integration of soft- ware interfaces giving a user direct access to this functionality has been shown to be a potential security risk, allowing a privileged adversary to indirectly tamper with sensitive computations. This thesis summarizes the results of various papers showing that using DVFS features, unsuitable voltage/frequency values can be set for the processor leading to hardware faults and calculation errors which can be used to undermine the integrity of Trusted Execution Environments (TEE). Results are partially replicated for Intel’s TEE implementation SGX, followed by extending the same methodology to AMD’s Zen Pro- cessors, on which there is currently no information. Results show that undervolting is an unlikely attack vector. iii Zusammenfassung Dynamische Spannungs- und Frequenzskalierung (engl. DVFS) ist ein in modernen Prozessoren vorhandener Leistungs- und Stromverwaltungsmechanismus, womit Span- nung und Frequenz der CPU je nach Bedarf skaliert werden können. Somit wird nicht nur Strom gespart, sondern auch zusätzlich verhindert, dass der Prozessor überhitzt. Die zunehmende Integration von Softwareschnittstellen zu diesen Mechanismen die dem Nutzer Einstellungsmöglichkeiten anbieten, haben sich zunehmend als potenzielle Sicherheitslücke erwiesen. -
High Performance Linpack Benchmark on AMD EPYC™ Processors
High Performance Linpack Benchmark on AMD EPYC™ Processors This document details running the High Performance Linpack (HPL) benchmark using the AMD xhpl binary. HPL Implementation: The HPL benchmark presents an opportunity to demonstrate the optimal combination of multithreading (via the OpenMP library) and MPI for scientific and technical high-performance computing on the EPYC architecture. For MPI applications where the per-MPI-rank work can be further parallelized, each L3 cache is an MPI rank running a multi-threaded application. This approach results in fewer MPI ranks than using one rank per core, and results in a corresponding reduction in MPI overhead. The ideal balance is for the number of threads per MPI rank to be less than or equal to the number of CPUs per L3 cache. The exact maximum thread count per MPI rank depends on both the specific EPYC SKU (e.g. 32 core parts have 4 physical cores per L3, 24 core parts have 3 physical cores per L3) and whether SMT is enabled (e.g. for a 32 core part with SMT enabled there are 8 CPUs per L3). HPL performance is primarily determined by DGEMM performance, which is in turn primarily determined by SIMD throughput. The Zen microarchitecture of the EPYC processor implements one SIMD unit per physical core. Since HPL is SIMD limited, when SMT is enabled using a second HPL thread per core will not directly improve HPL performance. However, leaving SMT enabled may indirectly allow slightly higher performance (1% - 2%) since the OS can utilize the SMT siblings as needed without pre-empting the HPL threads.
