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

qrun(8B) PBS qrun(8B)
NAME
qrun - run a pbs batch job
SYNOPSIS
qrun [-a] [-H host] job_identifier ...
DESCRIPTION
The qrun command is used to force a batch server to initiate the execution of a batch job. The job is run regardless of scheduling posi-
tion, resource requirements, or state.
In order to execute qrun, the user must have PBS Operation or Manager privilege.
OPTIONS
-a Specifies the job(s) is to be run asynchronously.
-H host Specifies the host within the cluster on which the job(s) are to be run. The host argument is the name of a host that is a
member of the cluster of hosts managed by the server. If the option is not specified, the server will select the "worst
possible" host on which to execute the job.
OPERANDS
The qrun command accepts one or more job_identifier operands of the form:
sequence_number[.server_name][@server]
STANDARD ERROR
The qrun command will write a diagnostic message to standard error for each error occurrence.
EXIT STATUS
Upon successful processing of all the operands presented to the qrun command, the exit status will be a value of zero.
If the qrun command fails to process any operand, the command exits with a value greater than zero.
