Relating the Execution Behaviour with the Structure of the Applicationrogram. In this paper, we show how the use of KappaPi automatic analysis tool helps the programmers of applications to avoid this difficult task. In the last stage of the analysis we discuss the possibilities of establishing relationships between the performance information found and the programming

Flattening on the Fly: efficient handling of MPI derived datatypes in MPI communication functions. The rationale behind the . mechanism is to alleviate the user from tedious packing and unpacking of non-consecutive data into contiguous communication buffers. Furthermore, the mechanism makes it possible to improve performance by saving on internal buffering. Appare

PVM Emulation in the Harness Metacomputing System: A Plug-In Based Approachmputational grids. Harness is an experimental metacomputing system based upon the principle of dynamic reconfigurability not only in terms of the computers and networks that comprise the virtual machine, but also in the capabilities of the VM itself. These characteristics may be modified under user

Implementing MPI-2 Extended Collective Operationssuch a project based on existing algorithms. The focus is on the intercommunicator operations, as these represent the main extension of the MPI-2 standard on the MPI-1 collective operations. We expose the algorithms, key features and some performance results. The implementation was done on top of WM

Comparison of PVM and MPI on SGI multiprocessors in a High Bandwidth Multimedia ApplicationPI as well as with data parallel language extensions. The approaches try to take advantage of the possibilities the respective programming interfaces offer. Experimental results are conducted on an SGI POWERChallenge GR and an SGI Origin 2000. These results show a good comparison of the programming
