CREAM is a CE program used by many sites based on UMD middleware to handle grid computing jobs. CREAM can be combined with various local batch programs, but it did not work with the HTCondor batch program. Since KISTI has been using HTCondor for many years, we searched another CE program which can work with HTCondor to process grid computing tasks. We proposed HTCondor-CE as the CE program, but it was not smoothly compatible with the UMD middleware environment because the OSG developed the HTCondor-CE software. In 2017, we manually configured HTCondor-CE and deployed a new CMS Tier-2 Center using the HTCondor-CE and a local HT-Condor cluster in the UMD middleware environment. The center has passed a SAM test suite that confirms the CMS computing performance of the center.
