 |
|
Does Portland Visual Fortran for Windows (v10.4) support CUDA in the same way as the linux version? I have a simple code that works fine with pgf90 version 10.4 on linux, but I get an error, "copyin Symbol Memcpy FAILED:13" using PVF 10.4 on Windows.
Any ideas? Thanks,
Todd

module cudamod
implicit none
integer, device :: int_d(1)
contains
attributes(global) subroutine foo
end subroutine foo
end module cudamod
program fcuda
use cudafor
use cudamod
implicit none
integer :: int_h(1)
int_h = 0
int_d = int_h
end program fcuda

Hi Todd,
This is a known compiler error (TPR#16346) that only occurs on 32-bit Windows when copying array data from a host routine to a module's global data. I just increased the priority of this problem (you're the first external report of this problem) and hopefully we can have it fixed shortly.
The work around is to use 64-bit Windows.
Thanks,
Mat |
