Attempt to view AOCL profile info results in java NullPointerException

Thank you for the report. I will try to replicate the issue.

There were a couple of profiler bugs that were fixed in 14.1; this may be one of them. I recommend updating, if possible.

Hi Outku,

Thanks for the reply and for your advice.

Actually, I have contacted Altera's support yesterday and they suggested the same: a clean install of Quartus 14.1, which I did.

Unfortunately, tough the error message changes slightly, the problem seems to remain (c.f. screenshot attached).

By the way, support member pointed out that environment variables needed to be set correctly, which I checked successfully (ALTERAOCLSDKROOT, QSYS_ROOTDIR and QUARTUS_ROOTDIR).

did you try to rebuild .aocx and rerun the host to produce profile.mon with 14.1? Or, did you just do "aocl report" with the 14.1 using your 14.0 old files?

I tried the jpeg_decoder here with 14.1 and the profiler works as expected.

Good thing that you mentioned it! Actually, I have not rebuilt the .aocx using 14.1. I only re-used the .aocx and profile.mon I originally obtained using 14.0.

I will try that as soon as I can and keep you updated on the result. Thanks.

I tried to correct a typo on the original post I wrote in this thread but saving the changes I made completely deleted it! Sorry...

Here is what I wrote in my original post:

Hi all,

I started working with Altera OpenCL a few weeks ago and I am still trying to get familiar with the collection of tools provided with the Altera SDK for OpenCL.

Right now, I am having trouble to get the AOCL profile information viewer up and running as any attempt to launch it results into the following error:

"Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException".

Any idea on how to get rid of this exception?

The system I am currently using runs Windows 7 (64-bits) and has a Stratix V FPGA board connected via PCIe.

Also, I am working with Altera SDK for OpenCL v14.0.2.209 and the application I used is the JPEG Decoder Design Example provided by Altera:

http://www.altera.com/support/examples/opencl/jpeg-decoder.html

Here is a description of steps I went through:

- Compiled the jpeg_decoder.cl kernel to obtain the .aocx file including profiling instrumentation

Command: "aoc --profile -v --board s5phq_d5 device/jpeg_decoder.cl -o bin/jpeg_decoder.aocx"

- Imported the Visual Studio project to VS2013 and built it to obtain the jpeg_decoder.exe executable (copied to bin directory)

- Ran the application to generate the profile.mon file

Command: "jpeg_decoder.exe 1.jpeg 1.ppm"

- Invoked the AOCL profile information viewer

Command: "aocl report jpeg_decoder.aocx profile.mon"

Attached is a screenshot of the actual error message.

Thanks!

David
