Roofline analysis on remote machine does not find sources

Hello,

I'm currently trying to run a roofline analysis on a remote machine. My approach is to run first "advixe -collect roofline" on the remote machine and then create a snapshot with "advixe -snapshot" and transfer the snapshot to my work machine. If I create the snapshot with "-cache-binaries -cache-sources -no-pack" I expect to see some source files copied to "SNAPSHOT/source_cache/temporary_files", but that folder is empty. The most important sources are in the working directory, so "--search-dir all:=./" should be sufficient for the parts I'm interested in. Additionally, I observe the correct behaviour on my local machine.

To be clear, I used the following commands and got this output:

advixe-cl -collect roofline -project-dir /home/marckoch/advisor-results/unstructured/poisson --search-dir all:rp=./ -v -- poisson_block_16_novec poisson_block_16_novec.ini
advixe: Warning: The Roofline is a special batch mode of data collection. It runs two analyses one by one. There are Survey Analysis and Trip Counts Analysis with FLOP respectively.

Hello,

Missed sources is not main issue there as I see. Minor issue is problem with time zone settings ("__bionic_open_tzdata_path: couldn't find any tzdata when looking for Europe/Berlin!") in system. Major issue is fail of tripcounts collection (second collection in roofline analysis): "Error: Cannot load data file `/home/marckoch/advisor-results/unstructured/poisson/e000/hs000/data.1/tripcounts_72641_0.tcs' (Data file is corrupted)."

Which Advisor was used there?

Hi Dimitry,

the version is

Copyright (C) 2009-2018 Intel Corporation. All rights reserved.
Intel(R) Advisor 2019 (build 570901)

on both machines.

Marcel,

Your Advisor version is a lot of outdated. Could You please try the freshest Advisor version?

Hi Marcel,

Just to clarify: do you see Roofline chart in the GUI, when opening "snapshot" on the remote ("destination") machine? I guess the answer is "YES" and so "tripcounts_72641_0.tcs" failure is likely unimportant issue (which you could possibly ignore; this could be just an indication of error in your service thread profiling or smth like that).

That's being said, upgrading to the latest Advisor version (as Dmitry suggested) still would be useful, because some regressions with source caching were addressed in latest update. Also, could you please try -pack flag to see if "packed snapshot" contains sources in fact?

And of course it is still interesting to check if "tripcounts_72641_0.tcs" failure disappeared.

Zakhar.

Hi Zakhar,

I have no means to view it on the remote machine, since X11 is not installed there. But I can see a Roofline chart, if I view the snapshot on my local machine, although the source view is not available. In that case, it doesn't matter if I use -no-pack or -pack.

This is the output from the newest Intel Advisor version (build 591264):

There are still corrupted files and the source files are still missing in the snapshot.

Thanks a lot! Could You plase share with me your snapshot to have a look on corrupted trace files?

Relative to missed source files: Could You please define full path to source files for --search-dir option e.g. --search-dir all:rp=/home/user/source_files_dir?

I get the same output and the missing source files if I use an absolute search path.

Thank You!

Corrupted trace files are not point of interest, - please ignore it. It should contain metrics for bash and tr utilities.

We will try to reproduce issue with missed source files locally.

Dmitry_Dontsov

We were able to reproduce the issue locally and will work for that. Currently I can suggest to define path to source files locally (from Project Properties window in GUI). It will allow You to see sources even if it not in snapshot.

Marcel_K_

I'm not sure I understand what you mean with that. If I open the snapshot on my local machine, I can't set the source or binary directory, since the snapshot is read-only.

If I copy the project directory from the remote system to my local system and open it there, I can set the source directory as usual. But I also must copy source and binary files from the remote machine. The source files are part of a quite large code base, so copying all of them is not really an option. Even copying the binary and some source files is not enough. Advisor is still missing source files.

I would like to reiterate that on my local machine it is sufficient to specify the working directory as the search dir.

Marcel,

Thank you. I think it is  now clear enough:-) Since we got reproducer from you - will work on the fix in upcoming Updates and also will probably share the pre-release build with you to check if our fix helps and to unblock you in this scenario.

Zakhar.

Marcel,

We have an early build we think may fix the issue. If you would like to test it, please submit a ticket on the Online Service Center: https://software.intel.com/en-us/support/priority-support

Marcel, 

2019 Update 4 (released in May'2019) should contain the fix. Could you please double-check if it worked fine for you?

Hi Zakhar,

yes the version 2019 update 4 works fine.

Thanks for your (and your co-workers) help.
