So are you saying that if I have a kernel with
struct test
{
int x;
}
__global__ go(test a)
{
... = a.x;
}
and call it with
go.prepare("s", ...) # tell PyCuda we're passing in a string buffer
go.prepared_call(grid, struct.pack("i",12345)) # pack integer into
string buffer
a.x will equal 12345 in the kernel?
I don't get any error messages but I just get garbage values for a.x.
