Libraries on Ibm Sp{2
نویسنده
چکیده
IBM SP{2 has become a popular MPP for scientiic community. Its programming environment includes several message passing libraries. In this paper, we analyse performance of communication operations in 3 libraries installed on SP{2, namely Parallel Virtual Machine (PVM), Message Passing Library (MPL), and Message Passing Interface (MPI).

متن کاملPerformance and Experience with LAPI - a New High-Performance Communication Library for the IBM RS/6000 SP
LAPI is a low-level, high-performance communication interface available on the IBM RS/6000 SP system. It provides an activemessage-like interface along with remote memory copy and synchronization functionality. It is designed primarily for use by experienced programmers in developing parallel subsystems, libraries and tools, but we also expect power programmers to use it in end-user application...
متن کاملPerformance Study of the MPI and MPI-CH Communication Libraries on the IBM SP
During our research in the simulation of message-passing applications on parallel, high-performance systems, we have discovered that the native MPI implementation on the IBM SP suffers from performance anomalies. Our simulator, MPI-Sim, predicted a smooth performance for an ASCI relevant application, whereas the measured system showed a sudden jump in the runtime of the application. Surprisingl...
