chunkIds

[<code><a rd-options="base" href="/link/data.frame?package=batchtools&version=0.9.10&to=base" data-mini-rdoc="base::data.frame">data.frame</a></code> or <code>integer</code>]
A <code><a rd-options="base" href="/link/data.frame?package=batchtools&version=0.9.10&to=base" data-mini-rdoc="base::data.frame">data.frame</a></code> (or <code><a rd-options="data.table" href="/link/data.table?package=batchtools&version=0.9.10&to=data.table" data-mini-rdoc="data.table::data.table">data.table</a></code>)
with a column named &#8220;job.id&#8221;.
Alternatively, you may also pass a vector of integerish job ids.
If not set, defaults to all jobs.
Invalid ids are ignored.

[<code>integer(1)</code>]
Requested number of chunks.
The function <code>chunk</code> distributes the number of elements in <code>x</code> evenly while
<code>lpt</code> tries to even out the sum of elements in each chunk.
If more chunks than necessary are requested, empty chunks are ignored.
Mutually exclusive with <code>chunks.size</code>.

n.chunks

[<code>integer(1)</code>]
Requested chunk size for each single chunk.
For <code>chunk</code> this is the number of elements in <code>x</code>, for <code>binpack</code> the size
is determined by the sum of values in <code>x</code>.
Mutually exclusive with <code>n.chunks</code>.

chunk.size

[<code>character(0)</code>]
If <code>ids</code> is a <code><a rd-options="" href="/link/data.frame?package=batchtools&version=0.9.10" data-mini-rdoc="batchtools::data.frame">data.frame</a></code> with additional columns
(in addition to the required column &#8220;job.id&#8221;), then the chunking is performed using
subgroups defined by the columns set in <code>group.by</code>.
See example.

group.by

[<code><a rd-options="" href="/link/Registry?package=batchtools&version=0.9.10" data-mini-rdoc="batchtools::Registry">Registry</a></code>]
Registry. If not explicitly passed, uses the default registry (see <code><a rd-options="" href="/link/setDefaultRegistry?package=batchtools&version=0.9.10" data-mini-rdoc="batchtools::setDefaultRegistry">setDefaultRegistry</a></code>).

This function is deprecated in favor of the more flexible <code>chunk</code>, <code>lpt</code> and <code>binpack</code>.

As a successor of the packages 'BatchJobs' and 'BatchExperiments',
this package provides a parallel implementation of the Map function for high
performance computing systems managed by schedulers 'IBM Spectrum LSF'
(<http://www-03.ibm.com/systems/spectrum-computing/products/lsf/>),
'OpenLava' (<http://www.openlava.org/>), 'Univa Grid Engine'/'Oracle Grid
Engine' (<http://www.univa.com/>), 'Slurm' (<http://slurm.schedmd.com/>),
'TORQUE/PBS'
(<http://www.adaptivecomputing.com/products/open-source/torque/>), or
'Docker Swarm' (<https://docs.docker.com/swarm/>).
A multicore and socket mode allow the parallelization on a local machines,
and multiple machines can be hooked up via SSH to create a makeshift
cluster. Moreover, the package provides an abstraction mechanism to define
large-scale computer experiments in a well-organized and reproducible way.

chunkIds function

[<code><a rd-options='base' href='data.frame'>data.frame</a></code> or <code>integer</code>]
A <code><a rd-options='base' href='data.frame'>data.frame</a></code> (or <code><a rd-options='data.table' href='data.table'>data.table</a></code>)
with a column named &#8220;job.id&#8221;.
Alternatively, you may also pass a vector of integerish job ids.
If not set, defaults to all jobs.
Invalid ids are ignored.

[<code>character(0)</code>]
If <code>ids</code> is a <code><a rd-options='' href='data.frame'>data.frame</a></code> with additional columns
(in addition to the required column &#8220;job.id&#8221;), then the chunking is performed using
subgroups defined by the columns set in <code>group.by</code>.
See example.

[<code><a rd-options='' href='Registry'>Registry</a></code>]
Registry. If not explicitly passed, uses the default registry (see <code><a rd-options='' href='setDefaultRegistry'>setDefaultRegistry</a></code>).
