Target resources: clustermq high-performance computing
Create the clustermq argument of tar_resources()
to specify optional high-performance computing settings
for tar_make_clustermq().
For details, see the documentation of the clustermq R package
and the corresponding argument names in this help file.
tar_resources_clustermq(template = list())

Named list, |
Object of class "tar_resources_clustermq", to be supplied
to the clustermq argument of tar_resources().
Functions tar_target() and tar_option_set()
each takes an optional resources argument to supply
non-default settings of various optional backends for data storage
and high-performance computing. The tar_resources() function
is a helper to supply those settings in the correct manner.
Resources are all-or-nothing: if you specify any resources
with tar_target(), all the resources from tar_option_get("resources")
are dropped for that target. In other words, if you write
tar_option_set(resources = resources_1) and then
tar_target(x, my_command(), resources = resources_2), then everything
in resources_1 is discarded for target x.
