c++ - SIMD or not SIMD - cross platform -

-

I need some idea how to write some of the parallel issues to the C ++ cross-platform implementation so that I can take advantage of it If possible, SIM (SSE, SP, etc.), I want to be able to switch between CIDD at run time. No SIMD.

How would you suggest me to face this problem (Of course I do not want to apply the problem several times for all possible options)

I can see how this can not be very easy to work with C ++ but I believe I'm missing something so far my idea looks like this ... A class CSTrim same area The array of will be used by many CSTEs Chana) I can achieve. Then using some funcents, I can create a fake lambda function which I need to implement on whole CSTrim. For example, I'm not expecting this code to be compiled cStream A; // something like the boat [1024] Seismide B; Sea Cream C; Zero Fu (for_each (AssignSIMD (c, MulSIMD (ADSIMD (A, B), A))); }

Where to increase the present indicator of e-mail streams, along with SIMD and without SIMD, it is responsible for inline the body of the Phantics.

Something like this: For example, I am not expecting this code, for which for_each (head and lieutenant; t & gt; f) {#ifdef USE_SIMD} (simdEnabled) real_for_each (f & Lt; true & gt; ()); // true means SIMD and #endif real_for_each (f false & gt; ()); }

Note that if SIM is enabled, then once it is checked and that it is around the main factor.

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
