Dear Igor,
For example the 2.0.5 compiler complains about this piece of code that
version 2.0.4 didn't really complain about:
private global val matrixTasks
:DistArray[subTask{self.home==here,self!=null}]; // At first I didn't put
the "{self.home==here,self!=null}" part but the compiler was complaining
def this(Matrix:Rail[double],vector:Rail[double],DimSize:int)
{
...................
...................
...................// Some code
...................
// Matrix creation
val D1:Dist=Dist.makeUnique();
matrixTasks
=DistArray.make[subTask{self.home==here,self!=null}](D1);
finish ateach((i):Point in matrixTasks.dist())
{
matrixTasks(i) =new subTask(taskDim); // here is the
problem LINE 38
}
}
ERROR:
<myPath>/myMVmult/MVmult.x10:38: Cannot assign expression to array element
of given type.
Expression: new subTask(...)
Type: subTask{self.home==here, self!=null}
Array element: MVmult.this.matrixTasks(i)
Type: subTask
Another question, is the rail "copyTo" and "copyFrom" still available?
Thanks alot
Regards,
Mohammed El Sayed
