Accomplishments:
- Held two-day meeting of the Joint Coordination Committee with CC-IN2P3, including a special HPC facility coordination meeting involving representatives from Argonne, NERSC, and Blue Waters.
- Intel Xeon-Phi-like architectures are looking more probable for big systems.
- NERSC Shifter provides containerization with increased security with docker compatibility.
- DOE is investing in OpenMP.
- Progress is occurring in the area of object stores; Argonne is interested in helping evaluate these.
- Back-ported HSC-developed parallelization code, including job submission and inter-process MPI messaging, as LSST
ctrl_poolpackage. This is expected to be a stopgap until process execution middleware with layering of functionality is available. - Changed the defaults for creating
coaddTempExps (single-visit images warped and trimmed to a coadd patch) to subtract the background and use alanczos3kernel. - Improved overscan correction for DECam data to handle “bias jumps”. Other ISR improvements are ongoing; “glowing edges” remain to be fixed.
- Published technical note about technical note publishing platform using that platform.
- Held differential chromatic refraction literature overview and discussion of ways forward.
Other items:
- Decommissioned old servers.
- Upgraded ActiveMQ message broker to 5.12.1.
- Fixed HealPix-based skymaps.
- Increased quotas on Nebula OpenStack cluster to accommodate increased usage.
- Updated DM risks in risk register.
Continuing work:
- Progress on detailed design of La Serena data center.
- Progress on detailed design of Level 1 systems, including investigation of possibility of elimination of the network outage buffer.
- Progress on operations proposal including draft WBS for operations.
