Containerize ALPS-DWA ?
- To maintain DWA further requires some effort. - One simple option would be to containerize DWA of course. With podman / runc in RHEL-8, this overhead is almost negligible. - Other virtualization option include conda.
I must admit that at the time DWA was written, we were at a different era. If given the time for another PhD with Matthias ( :) ), I would revamp this design to incorporate Kafka and Elasticsearch (++) - that supports built-in visualization and native-ETL support for modern big-data infrastructure.
The question now is really whether this code is worth our effort to improve further? (I wrote DWA, so I would be the best person to be assigned this task…)
Well, I leave this question to the community, and Matthias would have a bigger vote :)
If yes, how many man-days would we assign to this task?
Kind regards, Tama MA

Hi, I want to compile DWA from source on Linux. As far as I know "old" DWA verions from ALPS 2.2 work fine, but require ancient GCC (gcc at most 5.5). Newer DWA from ALPS 2.3 compiles ok with some of new compilers (at the very least with clang), but it quickly crashes with segmentation fault (Oskar Prosniak email from from 22/02/2018).
The problem is that it is not so easy to install gcc on a new machines these days, as gcc5 uses some deprecated header files which have been removed from glibc 2.28 and newer (ustat.h). Downgrading glibc is not really an option.
Is there any option these days to compole any version DWA from source, preferably 7650 (with the intent of make a few small changes to the source code) in such a way the updated DWA code can be deployed eg. on cluster (that is without using old linux distribution, without downgrading glibc, and preferably without gcc-5).
