MRGcluster

Function that allows to apply parallel processing

The need for anonymization of individual survey responses often leads to many suppressed grid cells in a regular grid. Here we provide functionality for creating multi-resolution gridded data, respecting the confidentiality rules, such as a minimum number of units and dominance by one or more units for each grid cell. The functions also include the possibility for contextual suppression of data. For more details see Skoien et al. (2025) <doi:10.48550/arXiv.2410.17601>.

MRGcluster function

<dl><dt>nclus</dt>
<dd>Number of clusters to use for parallel processing. No parallelization is used
for <code>nclus = 1</code>.</dd>
<dt>...</dt>
<dd>arguments that should be evaluated in the cluster (can also be called later)</dd>
<dt>action</dt>
<dd>Defines the action of the function. There are three options:<dl>
 <dt>"start"</dt>
<dd>Starts a new cluster if necessary, reuses an existing if it has already been started</dd></dl></dd> <dt>"restart"</dt>
<dd>Stops the cluster and starts it again. To be used in case there are difficulties with the cluster,
 or if the user wants to change the type of the cluster</dd>
</dl>
<dt>clusType</dt>
<dd>The type of cluster; see <code><a href="/link/makeCluster?package=MRG&version=0.3.21" data-mini-rdoc="MRG::makeCluster">makeCluster</a></code> for more details.
The default of makeCluster is used if type is missing or NA.</dd>

<dd>File to direct the output, <code><a href="/link/makeCluster?package=MRG&version=0.3.21" data-mini-rdoc="MRG::makeCluster">makeCluster</a></code> for more details.</dd>
