MPI + Cluster SMP
Hola, he instalado mpich2 vs. 1.2.1p1 en un cluster de biprocesadores con las opciones por defecto (antes usaba ssm pero visto que se quedaba colgado, lo he dejado con nemesis).
El caso es que quisiera que cada vez que lanzo un job (por ejemplo de 2 procesos), cada proceso del trabajo se fuera ejecutando en una máquina diferente (hasta llegar al número máximo de máquinas) y no en la misma máquina. Es decir:
Trabajo A en 2 procesos:
Máquina 1:
CPU0 Ocupada
CPU1 No Ocupada
Máquina 2:
CPU0 Ocupada
CPU1 No Ocupada
Un saludin

sccheckd
sccheckd(1M) System Administration Commands sccheckd(1M)
NAME
sccheckd - service for the cluster configuration check utility
SYNOPSIS
sccheckd
DESCRIPTION
Note -
Beginning with the Sun Cluster 3.2 release, Sun Cluster software includes an object-oriented command set. Although Sun Cluster software
still supports the original command set, Sun Cluster procedural documentation uses only the object-oriented command set. For more infor-
mation about the object-oriented command set, see the Intro(1CL) man page.
The sccheckd service is the server side of the client-server cluster configuration check utility. This utility is called by the sccheck
command.
The inetd daemon starts the cluster configuration check service. The service reads the /etc/default/sccheck file at startup and during exe-
cution. The service logs diagnostics and error messages to syslog and the console. The sccheckd service has no direct connection to stdin,
stdout, or stderr.
The sccheckd service exits when the last client connection exits.
