Get or Set UNIX Priority (Niceness) of this R process.
get.my.priority() set.my.priority(priority = 15)
priority |
The UNIX priority, also called niceness, what the
UNIX commands nice and renice set,
(an integer number, usually in the
range -20 to 19, that we want to set the priority to). Generally,
ordinary users can only raise the priority, so it is an error to
try to set the priority lower than that returned by get.my.priority . |
Sets the priority of itself, the unix process that is executing this
R code. The command was written for use with the snow
package (for nicing slaves), using syntax something like
invisible(clusterEvalQ(cl, set.my.priority()))assuming a cluster
cl
has already been set up. It may also
be useful in other situations.
get.my.priority
returns the priority.
set.my.priority
returns no value. It has the side effect
of setting the priority.
