Describe a path mapping for use when setting up jobs on the cluster.
Arguments
- path_local
The point where the drive is attached locally. On Windows this will be something like "Q:/", on Mac something like "/Volumes/mountname", and on Linux it could be anything at all, depending on what you used when you mounted it (or what is written in
/etc/fstab)- path_remote
The network path for this drive. It will look something like
\\\\projects.dide.ic.ac.uk\\tmp\\. Unfortunately backslashes are really hard to get right here and you will need to use twice as many as you expect (so four backslashes at the beginning and then two for each separator). If this makes you feel bad know that you are not alone: https://xkcd.com/1638 – alternatively you may use forward slashes in place of backslashes (e.g.//projects.dide.ic.ac.uk/tmp)- drive_remote
The place to mount the drive on the cluster. We're probably going to mount things at Q: and T: already so don't use those. And things like C: are likely to be used. Perhaps there are some guidelines for this somewhere?
- call
The name of the calling function, for error reporting.
Examples
if (FALSE) {
# Suppose you have mounted your malaria share at "~/net/malaria"
# (e.g., on a Linux machine). You can tell the cluster to mount
# this as "M:" when running tasks by first creating a path
# mapping:
share <- windows_path("~/net/malaria",
"//wpia-hn.hpc.dide.ic.ac.uk/Malaria",
"M:")
# This share object contains information about how to relate your
# local and remote paths:
share
# When configuring the cluster you might pass this:
hipercow_configure("windows", shares = share)
