using c11 _generic there way map multiple types single value? eg: _generic(e, \ *: foo_expression, \ b **: foo_expression, \ c: foo_expression, \ enum d: bar_expression, \ void *: bar_expression) is there way group types? (this isn't valid syntax express intent) _generic(e, \ *: b **: c: foo_expression, \ enum d: void *: bar_expression) the reason ask args foo , baz can end being large expressions (which can't refactored functions) , way avoid lot of duplication good. note: if there no supported way using _generic , _could_ make varargs macro glue multiple args single value... #define generic_type_glue3(answer, arg0, arg1) \ arg0: answer, arg1: answer #define generic_type_glue4(answer, arg0, arg1, arg2) \ arg0: answer, arg1: answer, arg2: answer .... ... have many of these macros, use varargs wrapper automatically use right one, see: https://stackoverflow.com/a/24837037/432509 _generic(e, ...

i trying design distributed-scalable pipeline based on uima. how should decide on using uima ducc or uima on hadoop? missing out, if build on uima ducc rather hadoop or vice-versa? one dimension application characteristics. hadoop have big advantage i/o intensive applications. ducc should have big advantage large memory applications need run multiple pipeline copies in different threads achieve high cpu utilization. another dimension taking advantage of uima vs taking advantage of hadoop. ducc builds on base uima capabilities, providing many scale out options, built in performance metrics, , debugging support, based on core uima components. more complex uima pipeline bigger advantage ducc; example, complex processing flows can implemented directly in ducc have transformed map-reduce. for sufficient hadoop expertise, relatively simple uima analytic can integrated existing hadoop shop without having learn uima.
