new 4ee2ef2 [MINOR] Extended DML config for federated worker parallelism
4ee2ef2 is described below
commit 4ee2ef2b20095eca35dd5af8acee4d747a17c32e
Author: Matthias Boehm <[email protected]>
AuthorDate: Sun Mar 20 21:34:14 2022 +0100
[MINOR] Extended DML config for federated worker parallelism
sysds.federated.par_conn (number of concurrent connections in even loop)
sysds.federated.par_inst (instruction parallelism worker instructions)
For both, if the value is <=0, we use by default the number of virtual
cores as reported by the JVM.
