By default, the instance specifications will be read from the cluster;

the options ``--standard-alloc`` and ``--tiered-alloc`` can be used to

override them.

  This parameter holds the pairs of specifications and counts of

  instances that can be created in the *tiered allocation* mode. The

  value of the key is a space-separated list of values; each value is of

  the form *memory,disk,vcpu=count* where the memory, disk and vcpu are

  the values for the current spec, and count is how many instances of

  this spec can be created. A complete value for this variable could be:

  **4096,102400,2=225 2560,102400,2=20 512,102400,2=21**.

Many of the INI_/FIN_ metrics will be also displayed with a TRL_ prefix,

and denote the cluster status at the end of the tiered allocation run.

  This option overrides the instance size read from the cluster for the

  *standard* allocation mode, where we simply allocate instances of the

  same, fixed size until the cluster runs out of space.

  This option overrides the instance size for the *tiered* allocation

  mode. In this mode, the algorithm starts from the given specification

  and allocates until there is no more space; then it decreases the

  specification and tries the allocation again. The decrease is done on

  the metric that last failed during allocation. The argument should

  have the same format as for ``--standard-alloc``.
