The Teaching Machine is a software system for animation of computer programs. It allows the instructor in the classroom or the student on their own to single step through computer programs written in C++ or Java while observing the effect of each step on the state of a virtual machine. The state of the machine is represented in a number of ways including a presentation of the current state of e...
Cloud computing platforms are growing from clusters of machines within a data center to networks of data centers with resources spread across the globe. Virtual machine migration within the LAN has changed the scale of resource management from allocating resources on a single server to manipulating pools of resources within a data center. We expect WAN migration to likewise transform the scope ...
We introduce DVSA, distributed virtual shared areas, a virtual machine supporting the sharing of information on distributed memory architectures. The shared memory is structured as a set of areas where the size of each area may be chosen in an architecture dependent range. DVSA supports the sharing of areas rather than of variables because the exchange of chunks of data may result in better per...
This paper presents the overview of parallel computer models. Practical parallel machines which are parallel virtual machine (PVP), symmetric multiprocessor (SMP), massively parallel processor (MPP), distributed shared memory (DSM), and clusters of workstation (COWs) are described. According to the classification of practical parallel machines, this paper mainly deals with distributed shared me...
In modern processors, the dynamic translation of virtual addresses to support virtual memory is done before or in parallel with the first-level cache access. As processor technology improves at a rapid pace and the working sets of new applications grow insatiably the latency and bandwidth demands on the TLB (Translation Lookaside Buffer) are getting more and more difficult to meet. The situatio...
In this work, we propose a new distributed run-time environment, which we called cJava, that enables multithread Java applications to execute in clusters transparently. Our implementation of cJava supports the distributed shared memory (DSM) which required significant extensions to the original Java virtual machine (JVM). First, a distributed object manager was incorporated to the JVM’s memory ...
We present a runtime environment that implements a Java Virtual Machine by co-execution between the different functional units of the heterogeneous Cell multiprocessing platform. Our approach uses the Cell’s scratchpad memory as a software-controlled cache and contains an automatic software-based memory management system for instruction and data caching. Profiling shows a cache hit rate of abov...
Shared memory systems, such as SMP and ccNUMA topologies, simplify programming and administration. On the other hand, clusters of individual workstations are commonly used due to cost and scalability considerations. We have developed a virtual-machine-based solution, dubbed vNUMA, that seeks to provide a NUMA-like environment on a commodity cluster, with a single operating system instance and t...
Memory forensics is the branch of computer forensics that aims at extracting artifacts from memory snapshots taken from a running system. Even though it is a relatively recent field, it is rapidly growing and it is attracting considerable attention from both industrial and academic researchers. In this paper, we present a set of techniques to extend the field of memory forensics toward the anal...
