Low-latency and offline
Low-latency h(t) reconstruction server (Aug - Oct/31: DT,SH,TY,NK,...)
- We already have two computing nodes to test the offline h(t) reconstruction via frame file but we need to install another for the low-latency h(t) reconstruction via shared memory inside the tunnel
- (Aug/20-) Connection and software test between a prototype PC and a test bench
- Prototype PC is just a standard desktop PC and will be prepared by SH
- (Aug-Sep) Procurement of server (2U height, at least two 10G network card, standard CPU,memory and disk)
- According to Darkhan’s test with LIGO data and discussion with LIGO people, standard spec should be OK.
- DT is working to figure out the spec and model.
- Academia Sinica will make the procurement
- (Mid.Sep) Connection test between the server and the test bench
- We also need the collaboration with DMG people for the data transfer
- (Sep-Oct) Connection test between the server and the KAGRA online system
- We also need the collaboration with DMG people for the data transfer
Current tasks (May 26 - July 15):
Ask to LIGO CAL team for the detailed information of gstlal-calibration (DT) [status: ongoing | expected finish: N/A]
Make gstlal-calibration running on a machine at KAGRA (DT, SH) [status: ongoing | expected finish: Jul 15]
- Find names and versions of all prerequisite libraries
- Install prerequisites and gstlal-cal package on a machine at AS
- Test gstlal-cal pipeline on an AS machine
- Install prerequisites and gstlal-cal package on a machine at KAGRA
- Test the pipeline on a KAGRA machine
Progress so far (June 21):
- Ask LIGO CAL team for the detailed information of gstlal-calibration
(ongoing) gstlal-calibration maintainers in LIGO are helping to resolve some installation and testing issues.
- Find names and versions of all prerequisite libraries,
(done, entry from June 7) SH made progress on this, see gstlal installation
- Install required packages and the gstlal-cal package on a machine at AS
DT has written scripts for installing lalsuite and gstlal software on a clean CentOS7 distro based on SH's instructions. Scripts were uploaded to KAGRA-AS group's Gitlab repositories:
CI pipelines that build docker-lalsuite-cold and docker-gstlal-cold containers were set up to run on AS IoP machine.
- Test gstlal-cal pipeline on an AS machine
As a prerequisite to this task, DT reproduced a portion of LIGO h(t) from raw data with gstlal-calibration-v1.1.8 (w/ a "docker-gstlal-cold" image). This test was done on a private server (2-cores on Intel Xeon 2.4GHz, 8GB RAM).
Downloaded a few hours of bKAGRA Phase-1 data on AS machine.
(doing) Will try to reproduce C00 with gstlal-calibration. Details in
(to do) Verify the output of gstlal-calibration.
- Install prerequisites and gstlal-cal package on a machine at KAGRA
(done, entry from June 7) SH made progress on this, see gstlal installation.
Test the pipeline on a KAGRA machine gstlal tests
to do
- Documentation
(doing) Started documenting the work in KAGRA-AS group's Gitlab repositories:
Progress so far (June 7):
- Ask LIGO CAL team for the detailed information of gstlal-calibration
Communication with people working on LIGO gstlal has been initiated.
- Find names and versions of all prerequisite libraries,
SH made progress on this, see gstlal installation
- Install prerequisites and gstlal-cal package on a machine at AS
As a prerequisite to this task, SH worked on installation process for CentOS, DT for Debian.
The goal is to have a better understanding of what is happening under the hood when the gstlal-calibration package is compiled.
- Test gstlal-cal pipeline on an AS machine
As a prerequisite to this task, DT is currently trying to reproduce LIGO h(t) from raw data.
A sub-goal of this task is to come up with a gstlal code testing procedure.
DT addressed some questions to LIGO gstlal people.
- Install prerequisites and gstlal-cal package on a machine at KAGRA
SH made progress on this, see gstlal installation
Test the pipeline on a KAGRA machine gstlal tests
to do
New tasks:
- Put more effort on documentation.
