    <p>You mention parallelism but not how you intend to make this project parallel. This is a much more complex issue than simply choosing a couple libraries. There are several major considerations required before moving forward.</p> <p>You mention the intended platform briefly, but you also have to consider whether the simulation will be run on a single computer/node or multiple. Considering that you are doing an iterative simulation of a building, you are probably going to require far more compute power than any one computer can provide. This means that, unless you want to go with a hybrid multiple-process, multiple-thread approach, you are limited to a multiple-process model of parallelism. OpenCL and MPI are then each options for your implementation. (note: MPICH and OpenMPI are each just implementations of MPI, and your code should be agnostic of these) Message passing with MPI is a good general model of parallelism however it can be quite difficult for those not used to working with parallel code. My personal experience is with MPI and some hybrid programming so I cannot say much else regarding your choice of parallel model.</p> <p>A problem that follows from the issue of the parallel model is that it directly impacts the simulation software. I am not entirely certain how separate you are planning on keeping your algorithm from the simulations. If you plan to have your code fork separate process to run the simulations, you will have issues with cross-platform support as you may not have the luxury of being able to run arbitrary simulations in this manner. If you instead intend to run the simulations within your software, the parallel model has to be consistent throughout. Although this puts limitations on the black box strategy, it may make the entire thing that much more feasible.</p> <p>A good deal has already been said about applicable libraries. I don't have any more to say about specific libraries that hasn't already been said. Just keep in mind that many of the same issues have to be addressed with these as when running the simulations.</p> <p>TLDR: Parallelism should not be looked over. You need to know which parallel model that you will be using before making decisions on libraries.</p>

    1. COThanks corahm for you input. Of all the topics I discussed in my original post, GUI programming and parallelism are the two topics I have the least experience with (close to none). I need to do some extensive reading in those fields. Could you suggest me any useful books or url's for parallelism?

    2. COIf you are interested in learning more about MPI, I have read Parallel Programming with MPI by Peter Pacheco which is somewhat older. He also wrote Introduction to Parallel programming which should also be good. Otherwise, a few Google searches on threading, message passing, OpenCL, etc can go a long way.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
