Hello,
I tried compiling the running X10 GPU examples provided in the
x10-trunk/x10.dist/samples/CUDA directory without success.
The error I get is:
async id 59 is not a CUDA kernel.
I understand this happens if the async construct is not marked
as @CUDA correctly, but I have not changed the examples at all.
This is my setup:
CUDA device information:
CUDA Device Query (Runtime API) version (CUDART static linking)
Detected 1 CUDA Capable device(s)

bytes)

Device has ECC support: Disabled
Device supports Unified Addressing (UVA): No
Device PCI Bus ID / PCI location ID: 0 / 0
Compute Mode:

simultaneously) >
deviceQuery, CUDA Driver = CUDART, CUDA Driver Version = 5.0, CUDA
Runtime Version = 5.0, NumDevs = 1, Device0 = GeForce 320M
X10 setup:
X10 svn version: r24750
X10 compiler compiled using: ant dist -DX10RT_CUDA=true
-Doptimize=false -DDISABLE_GC=true -DNO_CHECKS=true -DX10RT_MPI=true
The CUDA examples were compiled using the command:
x10c++ -O -NO_CHECKS CUDATopology.x10 -o CUDATopology (this
example works). Output of X10RT_ACCELS=ALL ./CUDATopology is:
Place: Place(0)
Parent: Place(0)
NumChildren: 1
Is a Host place
Child 0: Place(1)
Parent: Place(0)
NumChildren: 0
Is a CUDA place
No other examples work: they all tell me that async 72 is not a
CUDA kernel. I could not compile with the -STATIC_CALLS, because
the x10c++ compiler did not support it. These examples run fine
on the CPU. Also, I ran the examples like so:
x10RT_ACCELS=ALL ./CUDABlackScholes (for example).
Any help is appreciated.
