apologies if question has been asked before i'm finding hard word question in way might have been asked before. q: more efficient have like: mass[128] = {0.0} speed[128] = {0.0} age[128] = {0} or: properties[128] = {mass=0.0, speed=0.0, age=0} and why? there simple rule bear in mind, (are few larger arrays better many small etc)? i'm writing in js using chrome. reading , writing elements often. thanks much! in general, answer here is: makes sense let write simplest, clearest code; , worry performance or memory issue if run one. using array of objects named properties more efficient in terms of access time on modern javascript engine, , less efficient in terms of memory use. in both cases, difference incredibly minor , imperceptible. if values numbers , arrays can of fixed size, might use typed arrays , since arrays (where normal arrays aren't 1 unless javascript engine can optimization). there downsides typed arrays (their being fixed size, in...

how should declare method combine can take arguments in such way: function<list<string>,string> f1; function<string,list<integer>> f2; function<list<integer>,integer> f3; system.out.println(this.combine(f1)); system.out.println(this.combine(f1,f2)); system.out.println(this.combine(f1,f2,f3)); etc this generic object parameter indicating type of objects contains, in above example list of string thanks help thanks, right. method combine should return value of last function, so: obj obj = new obj(arrays.aslist(args)); string s = obj.combine(f1); list<integer> l = obj.combine(f1,f2); integer = obj.combine(f1,f2,f3) you can't overload combine method

this link says cublas-xt routines provide out-of-core operation – size of operand data limited system memory size, not gpu on-board memory size. means long input data can stored on cpu memory , size of output greater gpu memory size can use cublas-xt functions, right? on other hand, this link says "in case of large problems, cublasxt api offers possibility offload of computation host cpu" , "currenty, routine cublasxtgemm() supports feature. case problems input size greater cpu memory size? i don't difference between these two! appreciate if helps me understand difference. the purpose of cublasxt allow operations automatically run on several gpus. so, example, matrix multiply, or other supported operations, can run on several gpus. the cublasxtgemm routine has special capability, in addition parallelizing matrix multiply across 2 or more gpus, can parallelize across 2 or more gpus plus use host cpu additional computation engine. the matrix ...

what efficient way use pandas align , shift data add row 0 in or b columns if difference higher 2 abs, in order recursively make difference of a-b < 2 ex.- [column a] [diff - b] [column b] 0 0 0 4.54 4.54 0 <-- need add 0 shift 4.54 0 4.54 4.54 0 4.54 4.54 -3.04 1.5 after added [column a] [diff - b] [column b] 0 0 0 0 0 0 0 -4.54 4.54 <--recursive need same 4.54 0 4.54 4.54 0 4.54 4.54 -3.04 1.5 the whole idea push data match on lower diff. if notice need add , shift every time find diff absolute higher 2 on column or column b split dataframe before , after df0, df1 = df.iloc[:1], df.iloc[1:] create series of goes in between s = pd.series(0, df.co...
