Re: [HTCondor-users] Best Practices for Large HPC clusters for master and submitters

[Ram Ban <ramban046@xxxxxxxxx>]

Thanks for your suggestion,

My spool logs disks are not shared, but will increase there throughput and iopsÂ

Will check for if there is any use case for HPC_annex

I was particularly looking if I should change Collector/Scheduler file descriptors workers values as more workers might give more performance

Also is there any way to use for different ports to reduce network congestion on master?

Thanks and regardsÂ

Note there are some tuning tips in the online manual, hidden away at:
