As your later code shows, we extend 'a' to 'a '. The use of UBOUND(ca) gets an error because this has an array result. You want UBOUND(ca,DIM=1) instead. What do you think is a problem with that last example? When you get to the allocate, ca has already been allocated at ...
Could you help me to complete this code example?Here is my full C++ code: #include <iostream> extern "C" { void my_long_calc(void); void fortran_status(int* value); } void fortran_status(int* value) { std::cout << "Fortran current status = " << *value << std::endl; } int...
a .mypgirc file that has the settings that would be placed under the localrc for the install. This seems to allow me to compile trivial code (hello world, etc) but if you attempt to use the pgi cudo fortran features you get the same list of errors as displayed in the original post....
, which includes a CUDA Fortran version. SAXPY stands for “Single-precision A*X Plus Y”, and is a good “hello world” example for parallel computation. In this post I want to dissect a similar version of SAXPY, explaining in detail what is done and why. The complete SAXPY code is:...
