-----------------------------------------------------------------

briefly discussed this JIRA with Yury: looks like we've got two options to consider - either we do it all at Ignite side or additionally make some modifications in [BLAS|https://en.wikipedia.org/wiki/Basic_Linear_Algebra_Subprograms] ([netlib-java|https://github.com/fommil/netlib-java]). The open question for the latter is whether it's feasible licensing wise (BLAS is probably LGPL(?)). Also Yury suspects that [CacheUtils|https://github.com/apache/ignite/blob/master/modules/ml/src/main/java/org/apache/ignite/ml/math/impls/CacheUtils.java] may need to be rather heavily reworked along the way
