Find available graphics card memory using Fortran -

-

i using globalmemorystatusex in order find out amount of memory in system. there similar way find amount of memory on graphics card? here piece of code : 

use kernel32 use ifwinty  implicit none type(t_memorystatusex) :: status integer(8) :: retval status%dwlength = sizeof(status) retval =  globalmemorystatusex(status) write(*,*) 'memory available =',status%ullavailphys

i using intel visual fortran 2010 on windows 7 x64. thank you!

since tagged question cuda tag, i'll offer cuda answer. not sure if makes sense given environment.

i haven't tested on ivf, works on gfortran , pgi fortran (linux). can use fortran iso_c_binding module available in many implementations directly call routines cuda runtime api library in fortran code. 1 of routines cudamemgetinfo.

here's worked example of calling gfortran (on linux):

$ cat cuda_mem.f90 !======================================================================================================================= !interface cuda c subroutines !======================================================================================================================= module cuda_rt    use iso_c_binding    interface      !      integer (c_int) function cudamemgetinfo(fre, tot) bind(c, name="cudamemgetinfo")        use iso_c_binding        implicit none        type(c_ptr),value :: fre        type(c_ptr),value :: tot      end function cudamemgetinfo      !   end interface  end module cuda_rt    !======================================================================================================================= program main !=======================================================================================================================    use iso_c_binding    use cuda_rt    type(c_ptr) :: cpfre, cptot   integer*8, target   :: freemem, totmem   integer*4   :: stat   freemem = 0   totmem  = 0   cpfre = c_loc(freemem)   cptot = c_loc(totmem)   stat = cudamemgetinfo(cpfre, cptot)   if (stat .ne. 0 )       write (*,*)       write (*, '(a, i2)') " cuda error: ", stat       write (*,*)       stop   end if    write (*, '(a, i10)') "  free: ", freemem   write (*, '(a, i10)') " total: ", totmem   write (*,*)  end program main  $ gfortran -o3 cuda_mem.f90 -l/usr/local/cuda/lib64 -lcudart -o cuda_mem $ ./cuda_mem   free: 2755256320  total: 2817982464  $

in windows, need have installed cuda environment, (which presumes visual studio). need locate cudart.lib in install, , link against that. i'm not 100% sure link in ivf, since don't know if link way vs libraries link.
