Hey, it works! KMeansCUDA.x10 does compile and run, and it produces: points: 100000 clusters: 8 dim: 4
as output when run from the samples folder. Of course, it takes 47 seconds to compile and uses over 500 MB of RAM doing so, but at least it succeeds! CUDABlackScholes.x10 still fails mysteriously, this time at runtime with a segmentation fault. I'm on a Macbook testing this, not on a cluster, so really all I have to do is find a benchmark that runs in C++ with MPI and compare it to an X10 program that does the same thing and I should have a picture on the small-scale performance of X10 (I know it won't be especially representative of the actual power of X10 on a large scale, but it would help me understand how fast the generated C++ is). In any case, I have plenty to do while waiting for the 2.1 release in October (like setting up my school's ghetto cluster of 13 circa-2000 Sun Netra X1 servers with 1 GB RAM each), so I won't be trying to compile the CUDABlackScholes benchmark again for a while (and even then it wouldn't run on the cluster of discarded servers due to zero support for CUDA). X10 looks pretty amazing, and I'm glad to see it is still going (unlike Fortress).
