To allow our example to compile with earlier compilers, we make extensive use of the macro __STDC__ which is defined only for ISO C compilation systems. Thus, the function's declaration in the appropriate header file is: #ifdef __STDC__ void errmsg(int code, ...); #else void errmsg...
Figure 9. Matrix Multiplication without Shared Memory The following code sample is an implementation of matrix multiplication that does take advantage of shared memory. In this implementation, each thread block is responsible for computing one square sub-matrix Csub of C and each thread within the ...
This behavior does not conform with ISO, but it results in faster code, with some loss in accuracy. The following specific changes occur in relaxed mode: Division by a constant is converted to inverse multiplication. Certain C standard float functions--such as sqrt, sin, cos, atan, and ...
