29.
Requesting licenses using old syntax:
-lnodes=3:dyna-mpi-Linux:ncpus=2 -ldyna=6,mem=100mb,software=dyna
is converted to the equivalent:
-l select=3:ncpus=2:mem=33mb: dyna-mpi-Linux=True
-l place=scatter
-l software=dyna
-l dyna=6
30.
Requesting licenses using old syntax:
-l ncpus=2,app_lic=6,mem=200mb -l software=app
is converted to the equivalent:
-l select=1:ncpus=2:mem=200mb
-l place=pack
-l software=app
-l app_lic=6
31.
Additional example using old syntax:
-lnodes=1:fserver+15:noserver
is converted to the equivalent:
-l select=1:ncpus=1:fserver=True + 15:ncpus=1:noserver=True
-l place=scatter
but could also be more easily specified with something like:
-l select=1:ncpus=1:fserver=True + 15:ncpus=1:fserver=False
-l place=scatter
32.
Allocate 4 vnodes, each with 6 CPUs with 3 MPI processes per vnode, with each
vnode on a separate host. The memory allocated would be one-fourth of the memory
specified by the queue or server default if one existed. This results in a different placement of the job from version 5.4:
-l nodes=4:ppn=3:ncpus=2
is converted to:
-l select=4:ncpus=6:mpiprocs=3 -l place=scatter
33.
Allocate 4 vnodes, from 4 separate hosts, with the property blue. The amount of
memory allocated from each vnode is 2560MB ( = 10GB / 4) rather than 10GB from each
vnode.
-l nodes=4:blue:ncpus=2 -l mem=10GB
is converted to:
-l select=4:blue=True:ncpus=2:mem=2560mb \
