In this paper, we describe an implementation of MPI-IO on top of the Direct Access File System (DAFS) standard. The implementation is realized by porting ROMIO on top of DAFS. We identify one of the main mismatches between MPI-IO and DAFS is memory management. Three different design alternatives for memory management are proposed, implemented, and evaluated. We find that memory management in th...

This paper presents a new direct matrix inversion-less analysis for radial distribution systems (RDSs). The method can successfully deal with weakly meshed distribution systems. (WMDSs). Being easy to implement, direct methods (DMs) provide an excellent performance. Matrix inversion is the mean reason of divergence and low-efficiency in power flow algorithms. In this paper, the performance of t...

Introdouction:The study aimed to compare the accuracy of proximal caries detection by dental practitioners using two different systems, direct digital system and conventional films, under routine environmental conditions. Materials and methods: Eleven extracted human posterior teeth were mounted on wax frames and were exposed using the direct digital system and conventional films. Seventy-four ...

nowadays, the development of anti cancer drugs is an important subject in pharmacology. bisphosphonates (b.p) are a great choice for design and production of the types of drugs which not only could perform as anti cancer agents but also could inhibit the function of acetyl cholinesterase (ache). ache hydrolyzes the acetylcholine (which is a neurotransmitter in nervous system) using the oh in i...

Because of the very high chip rate of global positioning system (GPS), P-code acquisition at GPS receiver will be challenging. A variety of methods for increasing the probability of detection and reducing the average time of acquisition have been provided, among which the method of Zero Padding (ZP) is the most essential and the most widely used. The method using the Fast Fourier Transform (FFT...

This draft addresses enabling the use of Remote Direct Memory Access (RDMA) by the Network File System (NFS) protocols. NFS implementations historically incur significant overhead due to data copies on end-host systems, as well as other processing overhead. The potential benefits of RDMA to these implementations are explored, and the reasons why RDMA is especially well-suited to NFS and network...
