+- `threads_compute`: The number of parallel execution cores to be created for data computing. It is used as multiApply::Apply parameter "ncores".
 
 Using more than 2 threads for the retrieval will usually be perjudicial, since two will already be able to make full use of the bandwidth between the workstation and the data repository. The optimal number of threads for the computation will depend on the number of processors in your machine, the number of cores they have, and the number of threads supported by each of them.
