Thanks for the quick response. This is the latest version available to me on machomebrew, 20161122 hasn't been packaged/ported yet; I don't know how to get it on my system.

Well, if you want the latest version installed easy from a tar ball then do as it is written in the latest release:

You can install GNU Parallel in just 10 seconds with:
  (wget -O - pi.dk/3 || curl pi.dk/3/) | bash

If you are logged in as normal user the new version would be in $HOME/bin/parallel

./hans

PS: Latest has the release name ('Trump') and it should be stable ;-)

Hi

You ran the test with version 20160922.
If possible upgrade to 20161122 and run your test again.

Hi,

I wanted to see how parallel behaves when one of the hosts is down. root@nope is down (host doesn't exist on the network and won't resolve), scanner-helper is up and running.

$ parallel --controlmaster --filter-hosts --eta -j2 -S root@nope,:,user@scanner-helper sleep ::: 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2
parallel: Warning: Could not figure out
parallel: Warning: number of cpus on user@scanner-helper. Using 1.
parallel: Warning: Could not figure out
parallel: Warning: number of cpus on user@scanner-helper. Using 1.
parallel: This should not happen. You have found a bug.
Please contact parallel@gnu.org and include:
* The version number: 20160922
* The bugid: host check too many col0: user@scanner-helper /bin/bash: parallel: command not found
* The command line being run
* The files being read (put the files on a webserver if they are big)

If you get the error on smaller/fewer files, please include those instead.

If I remove the --filter-hosts, I don't get the warning but of course I'm getting output about root@nope that can't be contacted.

Happy to provide more info if required.
