Altera opencl, Diff usage of Processors when using parallel compilation of Quartus.

Hi pengbo,

I am having a similar problem. In my case the base.sta.rpt is as follows:

+------------------------------------------+

; Parallel Compilation ;

+----------------------------+-------------+

; Processors ; Number ;

+----------------------------+-------------+

; Number detected on machine ; 24 ;

; Maximum allowed ; 4 ;

; ; ;

; Average used ; 1.57 ;

; Maximum used ; 4 ;

; ; ;

; Usage by Processor ; % Time Used ;

; Processor 1 ; 100.0% ;

; Processors 2-4 ; 19.0% ;

+----------------------------+-------------+

Also, my machine has 24 processors, but I am only able to use 4 processor.

I tried changing the settings in Quartus Prime Pro 15.2, Assignments > settings > Compilation Process Settings to "use all available processors", but the result is the same, I cannot use more than 4 processors.
