The prototypical GPU support in Chapel (described in the IPDPS publication) never made it back into Chapel's master branch, so is not readily available, as you note. It is available on a branch, but one that is so outdated by now that it's probably not worth going back to. GPUs are a case that we intend to return to, but are focusing more on KNL for the time being (trying to be early to that party). > I will reply at length to the above.

Once it starts to feel very narrow, we usually move it off-list (chapel_info <at> cray... being a non-public possibility; the SourceForge chapel-developers list being a narrower, but still public list -- though one that you need to subscribe to, at least temporarily, to be able to post to). > Abstractions that work for FE are applicable to lots of other areas of HPC > across a wide range of applications and industries. > > That said, part of the effort involves writing Chapel libraries that can > import/export models produced by an easily avaible commercial/open-source > preprocessors/postprocessors, i.e. modelling tools.

I wouldn't want to put words in their mouths, but generally I'd say that they fit the profile I characterized earlier: they like the promise of Chapel and are waiting for the performance to catch up. -Brad ------------------------------------------------------------------------------ BPM Camp - Free Virtual Workshop May 6th at 10am PDT/1PM EDT Develop your own process in accordance with the BPMN 2 standard Learn Process modeling best practices with Bonita BPM through live exercises http://www.bonitasoft.com/be-part-of-it/events/bpm-camp-virtual- event?utm_ source=Sourceforge_BPM_Camp_5_6_15&utm_medium=email&utm_campaign=VA_SF _______________________________________________ Chapel-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/chapel-users
