Arcsecond Images of CH3CN Toward W75N

CH3CN (J=6-5) was observed with a resolution of 2'' toward W75N using the BIMA interferometer. Two continuum sources were detected at 3 mm, designated MM1 and MM2 in previous studies. Alignment of two mm continuum sources with the outflow axis from MM1 suggests that these continuum sources may be the result of the outflow interacting with the interstellar medium. MM1 is coincident with compact CH3CN emission. CH3CN was not detected toward MM2. The distribution of optical depth is derived. An excitation analysis was not done because of large line optical depths.

Physics development of web-based tools for use in hardware clusters doing lattice physics

Jefferson Lab and MIT are developing a set of web-based tools within the Lattice Hadron Physics Collaboration to allow lattice QCD theorists to treat the computational facilities located at the two sites as a single meta-facility. The prototype Lattice Portal provides researchers the ability to submit jobs to the cluster, browse data caches, and transfer files between cache and off-line storage. The user can view the configuration of the PBS servers and to monitor both the status of all batch queues as well as the jobs in each queue. Work is starting on expanding the present system to include job submissions at the meta-facility level (shared queue), as well as multi-site file transfers and enhanced policy-based data management capabilities.
