Re: Proof Asynchronous Mode

Thanks a lot.

Creating chains with "http://" solved my issue but naturally slowed the analysis down.
I have installed a small Proof cluster getting together several computers using PoD and i was planning to keep datasets in the master node.
Now i also installed afdsmgrd for dataset management but can't find enough documentation for stand-alone running. On the other i really don't understand why workers don't accept usual paths.
Any suggestions?

Best,
Sinan Kuday
