cuda - Does nvcc have an equivalent of fsingle-precision-constant? -


GCC allows to save the problem of manually adding every literal continuity. Is there any convenient equivalent in NVCC?

I believe the answer is new architecture Not with)

The old Open 64-based compiler supported a huge range of command line options (though many did nothing). Possible to pass -Xcompiler = -fshort-double to force all double precision calculations into single precision, the compiler is automatically done for two precise floating points automatically Sm_10, sm_11 and sm_12 targets which were the lack of original double exact support. The old compiler is still used for calculation 1.x target, so it is still possible.

The new cicc LVVM front end (which is used for the devices; 1.x calculation capacity) is too much, very small list of arguments, and they are not AFAIK documents surrounding the poking code generation and Shows the following options for controlling output: 

  -information-line-information-device-c-kernel-params-are-restrict -restrict -disable-inlining- Wno-memory -space -disable-llc-opts -show-src -g -O3 -O0 -fmad = 0 -fmad = 1 -prec-div = 0 -prec-div = 1 -prec-sqrt = 0 -prec-Sqrt = 1 -ftz = 0 -ftz = 1 -m64 -m32   
 So I think However, you are out of luck, if you  really want to do , you may have the opportunity to write a Livmeela replaces double precision constants themselves floating in CIC emitted IR. It looks as if a person is asking at least one thing, and can give you a place to start.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
