[Condor-users] Fw: Problems about condor slots

Mailing List Archives Public Access	UW Madison Computer Sciences Department Computer Systems Lab

Hi All,

Recently we have installed the newest condor release version 7.4.1 in our clusters. We encountered the following problems on some nodes during the installation:

1. The slot number of some nodes in the condor pool mismatched the number of logic cpu cores, which could be seen from /proc/cpuinfo. The slot number of node9 we noticed from condor_status was 6, while the logic cpu cores we found from /proc/cpuinfo is 4. Detailed information can be found in the attachment.

2. After installed condor on some nodes, we started condor_master but nothing happened. We checked the MasterLog file, it gave the following error:

It seems there is some privilege problems with condor_config file, but we can not figure out which part is wrong.
