Declare shared memory in CUDA Fortran using thesharedvariable qualifier in the device code. There are multiple ways to declare shared memory inside a kernel, depending on whether the amount of memory is known at compile time or at runtime. The following complete code example shows various methods...
Both fortran and C access the same shared data DLL. The data is defined in a Common in Fortran and there is an equivalent mappingof the variables in a C definition. Amazingly it works!If in migrating to the Intel Fortran compiler, I implement the shared memory example (shared...

编译命令: gfortran test.f90 -fPIC -shared -o libexample.so
Example: Limit virtual memory to 16 Mbytes:demo$ ulimit -d 16000 In a csh shell, use the limit command. See csh(1).Example: Limit virtual memory to 16 Mbytes:demo% limit datasize 16M Each of these command lines causes the optimizer to try to recover at 16 Mbytes of data space....

For example, the following code example has values of m, n, and k of 3,200. To illustrate the shared memory strategy, each thread block calculates a 32×32 tile of C. The parameters for this case are as follows: ! dmma tile sizes integer, parameter :: wmma_m = 8 integer, ...
cp make.inc.examplemake.inc 然后我们编辑make.inc,对其中的LIB路径修改为我们的安装路径,即 BLASLIB = /home/leiyhn/LIBLapack/lapack-install/lib/librefblas.a CBLASLIB = /home/leiyhn/LIB/Lapack/lapack-install/lib/libcblas.a LAPACKLIB = /home/leiyhn/LIB/Lapack/lapack-install/lib/liblapack...
example% f95 -0 program -xbinopt=prepare a.o b.o c.f95只有使用 -xbinopt 编译的代码才能用 binopt(1) 优化。为执行 gprof 分析而使用 -xpg 编译的二进制代码不应与 binopt 一起使用,因为这两者不能兼容,结合使用会导致内部错误。缺省值为 -xbinopt=off。
