parallel processing - Scattered indices in MPI -

i'm trying divide array between processors such each 1 takes points different parts in array. example, if a = {1, 2, 3, 4, 5, 6, 7, 8} and i'm using 2 processors, want p 1 handle {1, 3, 5, 7} , , p 2 handle {2, 4, 6, 8} . when scaling large numbers of points (millions) , processors (128), tricky. in previous versions of function, gave p 1 first chunk of points, p 2 next chunk, , on (which easy mpi_gatherv ). is there way use mpi_gatherv make work, or way use mpi_send , mpi_receive achieve it? trouble mpi_gatherv while can specify indices processors send to, still puts of p 1 before p 2 before p 3 etc.

Does jQuery have any "find or fail loudly" methods? -

consider following jquery code: $('.child').closest('.parent').find('.sibling').hide(); at every step, if nothing found, jquery fail silently (for example, if there no .parent ). sometimes makes sense, means code nothing , have troubleshoot why. i'd option like: $('.child').closest!('.parent')... meaning "fail loudly if don't find this". (bonus if enabled when developing.) is there in jquery? there's none, make easily: object.keys($.fn).foreach(function(k){ var f = $.fn[k]; if (typeof f !=='function') return; $.fn['_'+k] = function(){ var o = f.apply(this, arguments); if (o && 'length' in o && !o.length) throw "loud"; return o; } }) $("body")._find("unexisting"); // throws loud alternatively, replace existing functions when in debug mode: if (debug_mode) { // let's more cautious explicit list time
