1.0.0.4 | Distributing Input-Files To All Available Hosts

[taner]

Hi Admin-Team,

I'm not sure whether it is a bug.
(Manually) submitted Files are not distributed to all available hosts.

Hello taner,

I just test it and you're right, same think for me only 1 host takes all files. I will see with Steinar.
Thanks for reporting.
Cheers.

Hi Taner and Ben,

I'm not able to reproduce this. I have tried with two different farms and they behave the exact same way:
Jobs are "evenly" distributed among the available hosts. But this CAN vary, depending on the number of jobs and the available job slots per host. For example; If you submit 3 jobs and you have a host that has 3 available job slots, it can, depending on where in the job chekcing cycle it is, take all jobs. But if you for example send 6 jobs and you have 3 servers set to take 2 jobs each, the jobs should be evenly distributed.

That said/written, the way jobs are "distributed" probably has some potential of improvements. However, due to the "no-master" design of FFAStrans, perfectly distributed jobs can never be 100% guaranteed.

Hi guys,

Ok, after several trie (with 1.0.0.4), all seems ok. Tests with 2 hosts :
- default -> files processed by the 2 hosts
- all hosts includes -> files processed by the 2 hosts
- all hosts excludes -> nothing happens
- 1 host exclude -> files processed by other host
- 1 host include -> files processed by the selected host.

So, first sorry Steinar for my first post, I was wrong. Then, Taner, you have to check if your farm is ok. Check the firewall settings for example.
Hope you find the issue.
Cheers.

Hi Taner,

You are right, and I have found the cause of this behavior. However, it's not a bug but a design flaw related to not having shared work cache. So thanks for notifying and it will be addressed in the next bugfix update!
