# ConCho : Configuration Choser
refactored because the code was hard to maintain and was hacked in lots of ways (handling of 4 servers per host). - the prices are now retrived from matinfo's downloaded pages - the derived prices (such as the price without cpu) are now automatically computed, rather than hardcoded from (hand computation) - although it's a bit dirty, the architecture of the code is more generic: - each configuration is now stored in a Config object, which is able to compute its price. - dell specific code is now decoupled into a separate file. warnings: - the refactoring is designed to handle the old price tables but this work is not finished (the code using the old price tables is broken at the moment) - the computed price is currently overestimated, as the price of the base memory dimms should be substracted - disks are not currently handled

a tool to help choosing the best quality price ratio for a compute node
added documentation on how to use it

usage:
```console
graffy@graffy-ws2:~/work/concho$ PYTHONPATH=. python3 ./tests/test1.py
```
made the results a bit more accurate by taking into account the dynamic frequency scaling (the frequency of some cpu is running at lower frequency when executing avx512 instructions)
