using cilkview and cilkscreen

[newport_j]

Where is their some instruction or document on using cilkview and cilkscreen? I do believe that what is in the Programmer's Guide is current/correct. It seems that cilkview at least has a lot of different functionality.

Where can learn about hw to use cilkview and cilkscreen as they exist today?

Thanks in advance.

Hello,

the latest documentation is contained in Intel Cilk Plus Software Development Kit. After extracting there will be a sub-directory called "doc" which contains one HTML file.

There's an out-dated knowledge base article, too:
http://software.intel.com/en-us/articles/visualizing-parallel-speedup-with-cilkview/

I'm currently about to revise it.

Best Regards,

I know that some hahve chaged since that outdated document, but to will still hacve to use

cv.start

cv.stop

and

cv.dump

?


I just need to know what must be in the c source code to use cilkview reliably. It seems the old methods (without the cilk object) are okay.

Any help appreciated.

Hello,

didn't my answer on this thread help you:

? (reply #2)

It's exactly the same approach.

cv.start/stop/dump are not used anymore. Instead, use:

[bash] cilkview_data_t start; __cilkview_query(start); // profile this here __cilkview_report(&start, NULL, "my_tag", CV_REPORT_WRITE_TO_RESULTS); [/bash]

It is having trouble finding my cilkview.h file. It is in

../Desktop/cilkutil/include/cilktools/

which is not in my $PATH. How can I correct this?

1. I can makean additonal $PATH section to it (it is getting to be a long $PATH).

2. I can move cilkview.h, cilkscreen.h and any other header file in that cilkutil directory to another include file directory tha is in my $PATH.

I do not know which one is best or even if there is another way.

What can I/ should I do?

Any help appreciated. Thanks in advance.

Hello,

use "-I" like this

$ icpc -I/Desktop/cilkutil/include/cilktools/

...to help the compiler find the include directory for the cilktools' header files (here: cilkview.h).

You don't need to set $PATH; just use "-I" as described above.
