Hi guys,
I changed a little CUDAToplogy in order to obtain autoBlocks() and
autoThreads() from a GPU. I've copied the idea from KMeansCuda.x10, line
141.
When I try to compile I obtain the error below:
$ x10c++ -O -NO_CHECKS -STATIC_CALLS -o CUDATopology CUDATopology.x10
/home/rgomes/developer/workspace-x10/test-topology/src/CUDATopology.x10:57:
@CUDA Expected: val <something> = <autoBlocks/Threads or constant cache

This is a snippet where the error happened. See line 57.
for (c in children.values()) {
Console.OUT.println(" Child "+c.childIndex()+": "+c);
Console.OUT.println(" Parent: "+c.parent());
Console.OUT.println(" NumChildren: "+c.numChildren());
if (c.isCUDA()) Console.OUT.println(" Is a CUDA place");
if (c.isHost()) Console.OUT.println(" Is a Host place");
if (c.isSPE()) Console.OUT.println(" Is a SPE place");
if (c.isCUDA()) {
val gmemory = CUDAUtilities.makeRemoteArray[Int](c, 2, 0);
finish async at (c) @CUDA @CUDADirectParams {
gmemory(0) = CUDAUtilities.autoBlocks(); // line 57
gmemory(1) = CUDAUtilities.autoThreads();
}
val hmemory = new Array[Int](2, 0);
finish Array.asyncCopy(gmemory, 0, hmemory, 0, 2);
Console.OUT.println(" blocks = " + hmemory(0));
Console.OUT.println(" threads = " + hmemory(1));
}
}
I'm running x10-trunk, compiled with CUDA support.
Any idea?
Thanks a lot.
Cheers :)
