High-level Summary

Community Interactions, Meetings and Workshops

DM successfully completed the Joint Status Review (Aug 31- Sept 3) receiving a single recommendation. The DMLT met virtually (15th-17th) to discuss technical issues and planning.

The MOPS team held a joint exercise with the Minor Planet Center to test the ability to link objects, submit to the MPC, receive a new orbit catalog, and attribute observations to known objects.

Local Network Review for Chile was held with an external panel to assess the suitability of the Cisco ACI in the control network. The panel recommended that we migrate the control network to a NX-OS based system.

Technical Progress

Documents released:

SQR-049 detailing the design for the token management component of our Identity Management System.

Technote DMTN-155 detailing the interim model for community support was issued and circulated to the community

Nublado (the Science Platform notebook service) was deployed with JupyterLab 2.0

Single frame processing (for alert generation) of over 20,000 ccd visits of very crowded fields, comprising two bands from DECam of the galactic bulge, was successfully completed.

Substantial improvements to the Gen3 command-line tools, calibration handling, ingest performance, and workflow system compatibility were delivered. A Task to mask streaks is now available in the codebase for testing and is currently being used to mask satellite trails during the coaddition process. The Forward Global Calibration method (FGCM; Burke et al, 2018) was made our default photometric calibration algorithm for processing Hyper Suprime-Cam precursor data.

At NCSA a large maintenance activity was undertaken including moving lsst-login* nodes into a role as single jump hosts for all LSST resources. A GPFS upgrade to version 5.0 and upgrade of all hosts to latest patches was carried out, a requirement for two-factor authentication for all LSST resources in place.

Risk Management

The DM Risk Register was reviewed in the monthly process. No new risks were added and no significant changes were made to the existing exposure.
