Re: trouble about Underscore and Boolean
Hi! Are you talking about Schema Import Utility? If yes, then it is expected behaviour. Schema Import Utility generates POJOs using java naming convention. To overcome this you may use query fields aliases. But Schema Import Utility with this option (checkbox on UI) will be available in upcoming 1.6 release, or you could use latest nightly build from master. You could use only Schema Import Utility from nightly build and you app may remain on version you are using. About your second problem - could you provide a name of your RDBMs and table script? We will try to reproduce and fix. Hope this help.

trouble about Underscore and Boolean
dear experts, I meet troubles that very boring : trouble 1: I noticed that ignite generates fields without underscore... i.e. remove it if my table column : p_baseprice -> pBaseprice trouble2: ignite treats int(1) as Boolean how to indicate it as just integer??? please confirm if ignite is doing the above things and how to change them? I actually modified pBaseprice back to p_baseprice manually.(so boring...) but, after I change Boolean to integer. the starting ignite server process throws exception. I am in mess at all. please clarify if manual changes(from Boolean to Integer) work? i am modifying the "ServerConfigurationFactory.java" of course. -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/trouble-about-Underscore-and-Boolean-tp4840.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
Re: MPI / OpenMP compared to Ignite
Hi, OpenMP is like Ignite's Compute[1] subsystem running on the single JVM (because it uses shared memory). MPI is like Ignite's discovery SPI( and very limited, because MPI does not allow adding nodes dynamically after cluster start ) + communication SPI for message passing between nodes. Often OpenMP is used together with MPI forming hybrid model, which provides richer programming capabilities. Ignite provides out of the box things like computation load balancing and failover, distributed memory, job checkpoints, dynamic cluster membership, and much more compared to OpenMP/MPI. If you need such advanced capabilities in your OpenMP/MPI program, you must implement it yourself. Conclusion: Ignite provides much greater functionality compared to OpenMP/MPI, is written i Java, so you get safety, performance and coding speed. I see no point in using something instead of Ignite for distributed workloads. Disclaimer: I'am not an expert on OpenMP/MPI, so my opinion may be biased.
