Performance Evaluation of Intel EPT Hardware Assist

For the majority of common workloads, performance in a virtualized environment is close to that in a native environment. Virtualization does create some overheads, however. These come from the virtualization of the CPU, the MMU (Memory Management Unit), and the I/O devices. In some of their recent x86 processors AMD and Intel have begun to provide hardware extensions to help bridge this perform...

Use of Checkpoint-Restart for Complex HEP Software on Traditional Architectures and Intel MIC

Process checkpoint-restart is a technology with great potential for use in HEP workflows. Use cases include debugging, reducing the startup time of applications both in offline batch jobs and the High Level Trigger, permitting job preemption in environments where spare CPU cycles are being used opportunistically and efficient scheduling of a mix of multicore and single-threaded jobs. We report ...

Augmint -a Multiprocessor Simulation Environment for Intel X86 Architectures 1

Augmint is a fast execution driven multiprocessor simulator for Intel x86 architectures. It is based on MINT [1], but provides a user interface similar to that of Tangolite [2]. For the sake of simulation speed, processors are modelled as user level threads. A user de ned memory hierarchy simulator can be plugged into the simulator to study the behaviour of the architecture under consideration. 1.

No Compromise Performance and Security with Oracle’s x86 Intel-based Systems

Engineering Parallel Sorting for the Intel SCC

The Single-Chip Cloud Computer (SCC) is an experimental processor created by Intel Labs. It comprises 48 Intel-x86 cores linked by an on-chip high performance mesh network, as well as four DDR3 memory controllers to access an off-chip main memory. We investigate the adaptation of sorting onto SCC as an algorithm engineering problem. We argue that a combination of pipelined mergesort and sample ...
