18. Petra3: Mass Storage and Computing Requirements
Petra-3 experiments use central IT infrastructure wherever possible.
Users of the demanding experiments may not have sufficient resources at their home institutes.
Requests (demanding experiments)
Raw data:
260 TB/ year
Backup
Live time of big data sets ~ 6 months
To be decided: Archive
Computing power:
‘Near real time’ analysis for optimizing measurements
Offline: Reconstruction for demanding experiments
Setting up system tests
Data transfer speed: detector -> central file store
Processing speed
Remote access: data and compute cluster

Th. Kracht: DESY Status Report

20. PCIe – VME Interface: SIS1100/3100
Operational at DORIS beamline
Faster block transfer mode with 2.6 kernels
Performance comparison (Spectra command line):
Without block transfer mode
Loop/nloop=500 [* = read_mca( mca1, 0, nm, 8192)] -> 69s
Loop/nloop=500 [*=read_mca( mca1, 0, nm, 1024)] -> 8.6s
With block transfer mode
Loop/nloop=500 [* = read_mca( mca1, 0, nm, 8192)] -> 7.8s
Loop/nloop=500 [*=read_mca( mca1, 0, nm, 1024)] -> 1.0s
Loop/nloop=50000 [s1=rc(c1)] > 3.4s
New block transfer factor ~10 faster
Single IOs: 14.7 kHz (Spectra CLI)

Scans in Spock
Features that need to be implemented:
Scan types: single motor, time, energy, cm, hkl, angular, pseudo motor, 2D, 3D, continuous scans
Limits specifications: start/stop/delta, start/stop/np, range/np, regions, exafs regions
Options: automatic BS, automatic filter, MOSTAB, auto-return, dead time, log scales, update rate, repeats, SSA, etc.
Device selection: GUI and macro ->
Graphics: online monitoring, depends on the device selection and scan type
How it can be done
Scan types: Classes
Limits specifications: arguments
Device selection: measurement groups
Graphics: attributes of the mg groups ….
