Does the integration of Intel® Parallel Studio XE 2013 for Linux* and R lead to significant performance improvements? -

-
i running resource intensive computations in r. use for-loops, bootstrap simulations , on. have integrated intel® math kernel library linux* r , seems has lead significant improvement in computation times. thinking integrating intel® parallel studio xe 2013 linux* , r. means passing different compilers ship r: (1) integration of intel® parallel studio xe 2013 linux* , r lead significant performance improvements? (2) give examples in situations have benefit? thank you! very rough order of magnitude: parallel / multi-core blas such mkl scale sublinearly in number of cores but parts of operations blas calls ie not basic "for-loops, bootstrap simulation , on" byte-compiling r code may give factor of two, maybe three after may need heavier weapons such example rcpp can give 50, 70, 90-fold speedups on code involving "for-loops, bootstrap simulation , on" why eg popular mcmc crowd similarly, intel tbb , other parallel tricks require rewrites of

i've been working on large c++ project few weeks now. original goal use project learn c++11 , use pure c++ code , avoid manual allocation , c constructs. however, think problem going force me use c small function , i'd know why. basically have save function copy large binary file separate location before make changes data in it. files cd images max size of around 700mb. here original c++ code used: std::ios::sync_with_stdio(false); std::ifstream in(infile, std::ios::binary); std::ofstream out(outfile, std::ios::binary); std::copy(std::istreambuf_iterator<char>(in), std::istreambuf_iterator<char>(), std::ostreambuf_iterator<char>(out)); out.close(); in.close(); this code when used 690mb file takes barely under 4 minutes complete. have ran multiple files , it's same result; nothing under 3 minutes. however, found following way ran little bit faster, still fast c: std::ios::sync_with_stdio(false); std::ifstream in(infile, std::ios::binary); st

Best maven practices for modifying built war-file with generated resources -

-
currently i'm working on integrating grunt build process our maven build process. here 2 options can think of: pointing folder in resources target build dir grunt project. building grunt project wherever , enlisting this non-standard folders included resources in pom.xml. it looks there yet space enhancement. basically, since grunt subproject not depend on external resources, nice learn how not rebuild war-file had been compiled, modify after rebuilding grunt-project. so, question is: best practices adding generated resources existing war file. the approach of adding resources war file amounts modifying maven-built artifact after maven builds it. runs counter maven philosophy of tightly controlling entire build of every artifact. have 3 choices: include grunt generated source in war's source , build single artifact maven. in case rebuild war every time grunt resources change, or put grunt generated sources in second maven artifact , make artifact

how can loop through contents of file within robot framework? my file contents this: 1001 1002 1003 1004 i want read contents 1 one, assign variable , operations it. robotframework has several built-in libraries add lot of functionality. 2 can use task operatingsystem library , string library. you can use keyword get file operatingsystem library read file, , can use split lines keyword string library convert file contents list of lines. it's matter of looping on lines using for loop . for example: *** settings *** | library | operatingsystem | library | string *** test cases *** | example of looping on lines in file | | ${contents}= | file | data.txt | | @{lines}= | split lines | ${contents} | | :for | ${line} | in | @{lines} | | | log | ${line} | warn

c++ - std::map<> or std::vector<> when dealing with large sets of flags? -

-
i working on compiler , have large set of flags. in cases, nodes receive small number of flags (about 12 largest), total number of flags rather large (over 50.) flags integers defined in enum: enum flags_t { flag_one, flag_two, flag_three, [...] max_flag }; i thinking using std::map<flags_t, bool> makes more sense because of nodes use 0, 1, or 2 flags , number of nodes large (it can become tenth of thousands.) // map have check existing on avoid creating // useless entries in map bool node::get_flag(flags_t const f) { flag_iterator it(f_flags.find(f)); return == f_flags.end() ? false : *it; } void node::set_flag(flags_t const f, bool const value) { f_flags[f] = value; } but i'm wondering whether std::vector<bool> not end being more effective? although @ first sight looks good: bool node::get_flag(flags_t const f) { return f_flags[f]; } void node::set_flag(flags_t const f, bool const value) { f_flags[f] = value; }

rest - What is the best RESTful uri for a resource's tags -

-
say have resource of recipes , recipe can have tags. want list of tags used across recipes, uri be? /recipes/tags seems might work breaks convention of not pointing specific id such as: /recipes/1/tags you use: /tags but want tags recipes not other resource. use query params, such as: /tags?type-recipes and ftr, tags used recipes not other resource, seems misleading use query param since never recipes filters tricky -- when filter resource. you correct /recipes/tags problematic. go path variable of /resouce/{resouceid} /resource/{filter} can open whole word of pain. so first example go /recipes?tags={tags filter on} returns list of recipes based on tag the problem don't have lookup method acceptable tags are. expect /tags return list of tags , consume this /tags returns list of tags /tags/{tagid} returns meta data specific tag (what tag used for, superfluous in case if have recipe tags, more flexible) /tags/{tagid}/recipes returns
