linux - Would integration with DPDK be beneficial in terms of performance for a DNS/DHCP/DNSSEC server? -

-

dpdk seems provide impressive performance boost applications don't think servers benefit as things routers/switches.

i haven't seen mention of being done or worked on wondering if might worth working on.

dpdk on own provides layer 2 (i.e. ethernet) access device. first need build layer 3 (i.e. ip) , layer 4 (i.e. tcp/udp) stack on top of it. can use kni around this, don't think (somewhat small) performance benefits in case.

even after getting layers still wouldn't because odds packets getting application (the big thing dpdk optimizes) isn't bottleneck in dns or dhcp (unless perhaps simple, bare-bones implementations).

some other caveats include needing dedicate @ least entire core dpdk and, in cases, dpdk take on entire interface, meaning can't use else.

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl

python - PyCharm Type error Message -

i'm newbie trying out ml/dbn in python (3.4) under pycharm (comm.ed 4.5). following definition def make_thetas(xmin,xmax,n): xs = np.linespace(xmin,xmax,n) widths = (xs[1:] - xs[:-1])/2.0 thetas = xs[:-1] + widths return thetas throws error "class 'tuple' not define ' sub ', '-' operator cannot used on instance" on - operator on third line (widths = ....) ideas on how code running under pycharm - works alright in interactive python window. thx. to all, after g'g lot have found workaround seems work within pycharm. workaround because (even python newbie) expected python not need explicit typecasting, not when using datatypes imported lib such numpy. def make_thetas(xmin,xmax,n): xs = np.array(np.linspace(xmin,xmax,n)) widths = (xs[1:] - xs[:-1])/2.0 thetas = xs[:-1]+ widths return thetas using docstrings type-hinting such below did not work def make_thetas(xmin,xmax,n): "&q
