Cilk View has an error to report <1 parallelism

[Zhunping_Zhang]

Hello, I wonder if anyone has encountered this, I downloaded the new Cilk View:

~ > cilkview  -v
cilkview v2.0.2516.0
Copyright (c) 2010 Intel Corp.  All rights reserved

Running on one program on one core (CILK_NWORKERS=1) I obtained the following output:

cilkview: generating scalability data
Cilkview Scalability Analyzer V2.0.0, Build 2516

It also happened for 4-5 other programs. I wonder if this is a common bug, do I need to submit my program as test case somewhere?
