In the present work, we performed a discrimination analysis of the nonlinear equations used to describe sorption isotherms of the lettuce seeds. The equilibrium data were obtained by the static method using saturated salt solutions. The best model to describe the equilibrium moisture of lettuce seeds was selected using measures of curvature and bias. The obtained results showed that the Copace…

Abstract: The aim of the present review is to summarize the current evidence on the role of pelvic and para-aortic lymphadenectomy in endometrial cancer. In 1988, the International Federation of Obstetrics and Gynecology recommended surgical staging for endometrial cancer patients. However, 25 years later, the role of lymph node dissection remains controversial. Although the findings of two la…

Recently, Michaud questions the validity of weighted-IPC metrics by arguing that they are inconsistent and that weighted speedup favors unfairness [4]. Instead, he advocates us…

Memory bottleneck has always been a major cause for limiting the performance of computer systems. While in the past latency was the major concern, today, lack of bandwidth becomes a limiting factor as well, as a result of exploiting more parallelism with the growing number of cores per die, which intensifies the pressure on the memory bus. In such an environment, any additional traffic to memor…

On Optimal Kernel Size for Integrated CPU-GPUs – A Case Study
Integrated CPU-GPU architectures with a fully addressable shared memory completely eliminate any CPU-GPU data transfer overhead. Since such architectures are relatively new, it is unclear what level of interaction between the CPU and GPU attains the best energy efficiency. Too coarse grained or larger kernels with fairly low CPU - GPU interaction could cause poor utilization of the shared resou…

NVMain 2.0: A User-Friendly Memory Simulator to Model (Non-)Volatile Memory S…
Abstract—In this letter, a flexible memory simulator - NVMain 2.0, is introduced to help the community for modeling not only commodity DRAMs but also emerging memory technologies, such as die-stacked DRAM caches, non-volatile memories (e.g., STT-RAM, PCRAM, and ReRAM) including multi-level cells (MLC), and hybrid non-volatile plus DRAM memory systems. Compared to existing memory simulators, N…

Mitigating Memory-Induced Dark Silicon in Many-Accelerator Architectures
Many-Accelerator (MA) systems have been introduced as a promising architectural paradigm that can boost performance and improve power of general purpose computing platforms. In this paper, we focus on the problem of resource under-utilization, i.e. Dark Silicon, in FPGA-based MA platforms. We show that except the typically expected peak power budget, on-chip memory resources form a severe under…

Memristor-Based Multithreading
Switch on Event Multithreading (SoE MT, also known as coarse-grained MT and block MT) processors run multiple threads on a pipeline machine, while the pipeline switches threads on stall events (e.g., cache miss). The thread switch penalty is determined by the number of stages in the pipeline that are flushed of in-flight instructions. In this paper, Continuous Flow Multithreading (CFMT), a new …

LogCA: A Performance Model for Hardware Accelerators
To address the Dark Silicon problem, architects have increasingly turned to special-purpose hardware accelerators to improve the performance and energy efficiency of common computational kernels, such as encryption and compression. Unfortunately, the latency and overhead required to off-load a computation to an accelerator sometimes outweighs the potential benefits, resulting in a net decrease …

Exploiting Virtual Addressing for Increasing Reliability
A novel method to protect a system against errors resulting from soft errors occurring in the virtual address (VA) storing structures such as translation lookaside buffers (TLB), physical register file (PRF) and the program counter (PC) is proposed in this paper. The work is otivated by showing how soft errors impact the structures that store virtual page numbers (VPN). A solution is proposed b…
