dcp is a distributed file copy program that automatically distributes and dynamically balances work equally across nodes in a large distributed system without centralized state.
Due to the nature of the truncate option being in its own (cleanup) stage, when it fails, it sends control back to the copy stage which has no knowledge of the failure. This causes an infinite loop when the copy stage calls the cleanup stage again.
It would be useful to update the README.md text to indicate this project is abandoned and point explicitly to hpc/mpifileutils? It seems that the http://filecopy.org/ URL already directs there, but this is non-obvious.
