It uses the master-slave paradigm and I would like to convert this application to MPI. The master program displays some graphics on the XWindow server of the SPARC 20 system which is the host for the parallel processors. I have 4 Sparcs 20 on which I installed an run LAM 6.1 the be able to convert the application to MPI. I tried to run 4 slaves with "mpirun" and run my master directly from the Sparc as it was done in Trollius. In that way, the master see only one processor. I also tried to run 3 slaves (n1-3) and the master on n0 all with "mpirun". But the master started with "mpirun" is not able to display graphics on the Sparc X server. Questions: What about the combination LAM/MPI/X Window?? Is there someone on the list that ever had that kind of experience. Thanks in advance. -- ----------------------------------------------------------------------- _/_/_/_/ _/_/_/_/ _/_/_/_/ Patrice Hamelin ing. _/_/_/_/ _/_/_/_/ _/_/_/_/ Universite du Quebec a Trois-Rivieres _/_/_/_/ _/_/_/_/ _/_/_/_/ Ecole d'ingenierie, _/_/_/_/ _/_/_/_/ _/_/_/_/ Departement de Genie Electrique. _/_/_/_/ _/_/_/_/ _/_/_/_/ C.P. 500, Local LP-2501 _/_/_/_/ Trois-Rivieres, Quebec _/_/_/_/ Canada, G9A 5H7 _/_/_/_/ Tel: (819) 376-5011, ext. 3971 _/_/_/_/ Fax: (819) 376-5219 ----------------------------------------------------------------------- http://ecoleing.uqtr.uquebec.ca/geniedoc/ge/biochamps http://www.geocities.com/MotorCity/1517 -----------------------------------------------------------------------
