With the current version of X10, you can run the binary output by x10c++
directly. E.g. "./a.out". runx10 is not needed.
If I'm reading this correctly, x10c++ compiles your program ok, but you get
a runtime exception. A Null Pointer Exception, in one of your Array.copy
calls. I would try to figure out which of the Array.copy() calls is
throwing the exception, and check if you're going beyond the array bounds.

Hi
I compiled the code and working fine with Java-backend, but got error when
run with X10C++ compilation. See the error output, i see that
Array.copy(input,startIndex,subinput,0, endIndex-startIndex+1); hits ding.
(I also recompiled X10 from source for better computability, and I don't
see runx10 in the bin, is this new is that x10c++ no longer needs runx10?)
public static def enc(f:File, num_of_proc:int){
val keystring = "krww6anpovmkcqstubjuzmxcvzpb7c7d";
var input:Rail[Byte] = getBytesFromFile(f);
var sizes:Rail[int] = calPartitionInput(input.size, num_of_proc);
val l = new ArrayList[AES]();
for(var i:int=0,startIndex:int=0,endIndex:int=sizes(i)-1; i<sizes.size;
i++){
var subinput:Rail[Byte] = new Array[Byte](0..(endIndex-startIndex));
Array.copy(input,startIndex,subinput,0, endIndex-startIndex+1);
val aes = new AES(subinput, startIndex, keystring, "ENC");
startIndex = endIndex+1;
endIndex = startIndex+((i<sizes.size-1)?sizes(i+1)-1:input.size-1);
l.add(aes);
}
val s = Timer.milliTime();
finish{
for(var i:int=0; i<l.size(); i++){
val index = i;
async {
Console.OUT.println(index);
l.get(index).run();
}
}
}
val e = Timer.milliTime();
Console.OUT.println((e-s) + " milliseconds");
var newsize:int = input.size + (16 - (input.size % 16));
var output:Rail[Byte] = new Array[Byte](0..(newsize-1));
for(var i:ListIterator[AES]=l.iterator(); i.hasNext(); ){
val aes = i.next() as AES;
var size:int = (aes.input.size%16==0)?aes.input.size:aes.output.size;
Array.copy(aes.output, 0, output, aes.index, size);
}
val ext= f.getPath().substring(f.getPath().lastIndexOf(".")+1,f.getPath
().length());
val fn = f.getPath() + ".xenc."+ext ;
var f1:x10.io.File = new x10.io.File(fn);
var fw:x10.io.FileWriter = f1.openWrite();
fw.write(output);
Console.OUT.println("Done ENC");
}

Yes. It's now a typedef for Array[T]{rank==1,zeroBased,rect}. In older
versions of X10 it was a special, hand-optimized class distinct from Array.
The tool that generates the library documentation is based on javadoc and
doesn't quite understand X10's typedefs. If you look in x10.lang.Rail.x10
you'll find it:
[dgrove@wahtutca lang]$ more Rail.x10
