The IBM SP is one of the most powerful commercial MPPs, yet, in spite of its fast processors and high network bandwidth, the SP's communication latency is inferior to older machines such as the TMC CM-5 or Meiko CS-2. This paper investigates the use of Active Messages (AM) communication primitives as an alternative to the standard message passing in order to reduce communication overheads and t...

The aerosol penetration efficiency and quality factor for three Chemical Biological Radiological protective fabrics were evaluated using a particle counting technique. Both parameters characterise aerosol penetration through tested material; the latter accounts for the effect of fabrics air permeability. The overall and size dependent penetrations of 0.03–3 μm sized Sodium Chloride (NaCl) and D...

Abstract Next-generation networks are expected to combine advanced physical and digital technologies in super-high-speed connected system infrastructures, gaining critical operation competitiveness of improved efficiency, productivity quality services. Towards a fully world, these platforms will enable infrastructure virtualization support edge processing, making emerging sectors, such as Indus...

The thermoelectric generator (TEG) system has attracted extensive attention because of its applications in centralized solar heat utilization and recoverable energy. operating efficiency the TEG is highly affected by conditions. In a series-parallel structure, due to diverse temperature differences, modules show non-linear performance. Due non-uniform distribution (NUTD) condition, several maxi...

PVM (Parallel Virtual Machine) is a popular standard for writing parallel programs so that they may execute over a network of heterogeneous machines. This paper presents some performance results of PVM on three massively parallel processing systems: the Thinking Machines CM-5, the Intel Paragon, and the IBM SP-2. We describe the basics of the communication model of PVM and its communication rou...

This paper describes the intelligent cache controller of JUMP-1, a distributed shared memory type MPP. JUMP-1 adopts an off-the-shelf superscalar as the element processor to meet the requirement of peak performance, but such a processor lacks the ability to hide inter-processor communication latency, which may easily become too long on MPPs. Therefore JUMP-1 provides an intelligent memory syste...

Parallel computing on clusters of workstations is attractive because of the low costs in comparison to MPPs, but the speed of the local area network limits the class of applications that can be run efficiently. Fortunately, faster network technology is becoming available for the next generation of workstation clusters. This paper studies the effect of running challenging applications that commu...

Exploration of the aquatic microbiota of several circum-neutral (6.0-8.5 pH) mid-temperature (55-85°C) springs revealed rich diversities of phylogenetic relatives of mesophilic bacteria, which surpassed the diversity of the truly-thermophilic taxa. To gain insight into the potentially-thermophilic adaptations of the phylogenetic relatives of Gram-negative mesophilic bacteria detected in culture...

Adherent mammalian cells dynamically interact with their extracellular matrix (ECM) and culture substrate. To accommodate this sensitivity, standard culture techniques typically utilize tissue culture polystyrene (TCPS), a treated polystyrene substrate that promotes cell attachment. However, TCPS cannot be easily integrated into microfluidic devices as it is incompatible with conventional fabri...
