Conference submission along with submitting to arXiv I am about to submit an article to an international conference (http://www.mldm.de/). I am thinking also to submit to arXiv as well. Is there any problem with this?
The way journals handle arXiv submissions depends entirely on the journal. Generally, it should be allowed since arXiv is a well established service. The only way to know for sure is to read the FAQ/Terms and Conditions or ask the publisher/editor.
