Hi,
I think you attached wrong file. there is no changes the attachment. So
were you able to run it under Native back-end?
This is what i found out, so running with compiled version of X10 (instead of
pre-compiled version), this is what I got for output. Native version is way
longer than Java-backend, and java-version of AES is 21seconds for 18M file. I
expect Native version would run faster than Java-Backend

Subject: Re: [X10-users] AES in X10
A somewhat obscure problem, but a bug in your code.
In the run method you had
if( this.op == "ENC" ){
this.output = this.encrypt(this.input, this.key.bytes());
}else if(this.op == "DEC" ){
this.output = this.decrypt(this.input, this.key.bytes());
}else{
}
Strings are objects, so this was doing pointer equality. You really should do
this.op.equals("ENC"). You were getting lucky with the Java backend because
Java happens to share String objects between literals in the same class file.
The Native backend doesn't do this.
I changed to equals and it ran. Modified version attached.
