News: tar-compress; SardanaConfig, slow motors; new gpfs, pyspMonitor: cursor

GPFS (Konstantin): need an easy-to-use application which tar-compresses files in GPFS. Will be discussed with IT.

The topic has been discussed with IT. They find it interesting.

Discussion items: 
  - chose good chunk sizes for the containers carefully
  - what if containers are corrupted during transfer
  - note: data already uncompressed archived
  - interesting if new export system will be installed
  - this request ist related to other workflows, e.g. handle reduced beamtimes

IT will discuss internally.

configure change events for slow motors (P10): background: for very slow motors the frequency of the position update in spock may be not sufficient, solution: use /online_dir/SardanaConfig.py to configure the change events after SardanaAIO has been executed, an example can be found here

new gpfs:

IT plans to change the server types:

  - current status: ESS 5000, power-9, IB-100
  - planned: 
    + replace power architektur by x86 
    + use high capacities SSDs 40 TB, bigger, 
      slower, but internal compression
    + go for IB-200 (HDR): temperature problems need to be solved.

pyspMonitor (Fabian): make cursor functionality available in pyspMonitor, work has begun, waiting for input.
