Message Passing Interface (MPI) is a popular message passing interface for writing parallel applications. It has been designed to run over many different types of network interconnects ranging from commodity Ethernet to more specialized hardwares including: shared memory, and Remote Direct Memory Access (RDMA) devices such as InfiniBand and the recently standardized Internet Wide Area RDMA Prot...

MPI (Message Passing Interface) has become the de facto standard for implementing parallel programs on distributed systems. In MPI, the two basic communication primitives are pointto-point communication and broadcast respectively. In this paper, we evaluate and compare the performance of broadcast with point-to-point communication (both blocking and non-blocking) of the MPI-1 standard library o...

The ability to offload functionality to a programmable network interface is appealing, both for increasing message passing performance and for reducing the overhead on the host processor(s). Two important features of an MPI implementation are independent progress and the ability to overlap computation with communication. In this paper, we compare the performance of several application benchmark...

UNLABELLED Parameter estimation is crucial for the modeling and dynamic analysis of biological systems. However, implementing parameter estimation is time consuming and computationally demanding. Here, we introduced a parallel parameter estimation tool for Systems Biology Markup Language (SBML)-based models (SBML-PET-MPI). SBML-PET-MPI allows the user to perform parameter estimation and paramet...

Message-Passing Interface (MPI) has become a standard for parallel applications in high-performance computing. Within a shared address space, MPI implementations benefit from the global memory to speed-up intra-node communications while the underlying network protocol is exploited to communicate between nodes. But, it requires the allocation of additional buffers leading to a memory-consumption...

We describe an architecture f o r the runtime environment for parallel applications as prelude to describing how parallel application might interface to their environment in a portable way. We propose extensions to the Message-Passing Interface (MPI) Standard that provide for dynamic process management, including spawning of new processes b y a running application and connection to existing pro...

We describe an architecture for the runtime environment for parallel applications as prelude to describing how parallel application might interface to their environment in a portable way. We propose extensions to the Message-Passing Interface (MPI) Standard that provide for dynamic process management, including spawning of new processes by a running application and connection to existing proces...

The Message Passing Interface (MPI) is the most commonly used application programming interface for process communication on current large-scale parallel systems. Due to the scale and complexity of modern parallel architectures, it is becoming increasingly difficult to optimize MPI libraries, as many factors can influence the communication performance. To assist MPI developers and users, we pro...

The notion of communicators is one of the most central concepts in the Message Passing Interface (MPI), allowing the library developers to contextualize their message exchanges, and scope different algorithms to well-defined groups of processes, and allowing the MPI implementation to specialize its matching and deliver messages in the right context. Due to its collective nature, the communicato...
