The data should be supplemented with the values of the design variables. File formats that come into considerations are HDF5, SDDS, a NoSQL database, zip/tar gunzip etc.krausgselladelmannkraushttps://gitlab.psi.ch/OPAL/src/-/issues/614Make sampler more robust2020-10-09T10:33:26+02:00bellotti_rMake sampler more robust**Current state**<br />

If one machine configuration crashes (e. g. segfault), the entire random sample dies.
**Why is it bad**<br />
I'm referring to a situation where the sampler reads from a TSV file instead of generating configurations.<br />
- The more machines are run in parallel, the more configurations have to be restarted. This is a cumbersome manual process, and therefore error prone.
- All progress of simulations in progress is lost. (waste of resources)
- The unfinished machine settings have to be identified, copied to a new TSV file, and another RS has to be started, which is again a manual process.
Long story short, this bug imposes unnecessary work and introduces unnecessary error sources for OPAL users.
