Low-latency h(t) reconstruction server (Aug - Oct/31: DT,SH,TY,NK,...)

 * We already have [[KAGRA/Subgroups/CAL/WG/offline/gstlal|three 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
