Hi:
I'm new to here and may need to ask some question about this tool: Intel Trace Analyzer and Collector
Is this software intel Xeno exclusive or it can be multi-platform.
Also if our company want to purchase this tool, where should I ask?
Many thanks
Chi

Hi Chi,
Thanks for getting in touch. You should be able to run the Intel Trace Analyzer and Collector on any x86-based platform but it is meant to provide more detailed information on Xeon-based systems. The better question will be whether the Intel Trace Analyzer and Collector supports other MPI implementations aside from the Intel MPI Library. The answer is yes, if those implementations are MPICH-based. More details are available here, in our User's Guide.
The Intel Trace Analyzer and Collector is only available through the Intel Parallel Studio XE Cluster Edition bundle. Here are more details on how to evaluate or purchase the bundle.
Regards,
~Gergana

Hi Gergana:
Thank you for your reply, I'll take a look.

Hi Gergana:
Sorry to trouble you again.
I test it with the compatibility tool and it says OK. I have installed the trail-version of intel Trace Analyzer and Collector on our AMD system and use mvapich2.3.1, which the installation seems successful. Yet when I run the software with the trace-analyzer-collector, it reported an error message such as:
"
/codes/commercial/Intel/Parallel_Studio_XE/install/compilers_and_libraries_2019.3.199/linux/mpi/intel64/bin/mpirun: line 103: 31339 Floating point exception(core dumped) mpiexec.hydra "$@" 0<&0
"
It that something related to the installation or I missed other items to make it works?
Regards
Chi

Hi, Chi.
Could you provide your command line and full output that you see?

Hi Anatoliy:
Here is what I used:
source /codes/commercial/Intel/Parallel_Studio_XE/install/parallel_studio_xe_2019.3.062/bin/psxevars.csh
setenv FI_PROVIDER tcp
setenv VT_CONFIG VTconfig.conf
mpirun -trace -hostfile local.host.hyp -np 2 pimpleFoam -parallel
and it returns:
/codes/commercial/Intel/Parallel_Studio_XE/install/compilers_and_libraries_2019.3.199/linux/mpi/intel64/bin/mpirun: line 103: 89898 Floating point exception(core dumped) mpiexec.hydra "$@" 0<&0

Chi, do you observe this error only with -trace option?
Could you also check command lines bellow and provide the output:
1. I_MPI_DEBUG=5 mpirun -verbose -trace -hostfile local.host.hyp -np 2 pimpleFoam -parallel
2. FI_PROVIDER=sockets mpirun -trace -hostfile ...
3. mpirun -trace -hostfile local.host.hyp -np 2 hostname
4. I_MPI_HYDRA_TOPOLIB=ipl mpirun -trace -hostfile ...

Hi Anatoliy:
Thanks for the reply.
This error message shows after I 'source' the intel-trace-analyzer. I think even without the '-trace' option it still shows the same message.
Also, all the command lines / environment settings you provided I tried comes back with the same error message.
Maybe I missed something in the installation?
Many thanks
Chi

Chi, when you source psxevars.csh, you source and Intel MPI and Trace Analyzer and Collector. If it fails without '-trace' option then it is something wrong with Intel MPI.
Please check that `mpirun -n 1 hostname` also fails.
I don't think that something wrong in the installation.
HYDRA_BSTRAP_XTERM=1 variable can help to show where we get Floating point exception.
Please set this variable and run mpirun. After that you will see xterm windows with launched gdb. Then type `run` in each windows and you will see Floating point exception in one of the windows. Then type `bt`, it will show backtrace. Please send me this backtrace.

Hi,
I'm working with Chi on the above.
Having sourced the psxevars.csh file:
- mpirun -n 1 hostname does indeed fail
- With that env variable set, the command still fails, but doesn't seem to launch any xterm windows? (Checked DISPLAY as able to launch other X based windows from that terminal)
Do you have any further guidance?
Thanks,
Dan

Hi, Daniel.
Yes, please run the command lines bellow and provide me all output.
1. mpirun -verbose -n 1 hostname
2. HYDRA_BSTRAP_VALGRIND=1 mpirun -n 1 hostname
3. ${I_MPI_ROOT}/intel64/bin/cpuinfo

Hi Anatoliy:
Thanks for the reply.
They all come back the same error message:
'/codes/commercial/Intel/Parallel_Studio_XE/install/compilers_and_libraries_2019.3.199/linux/mpi/intel64/bin/mpirun: line 103: 26863 Floating point exception(core dumped) mpiexec.hydra "$@" 0<&0'
Even the 'cpuinfo' command line comes back as:
'Floating exception (core dumped)'

Hi,
It seems this is the same error like in https://software.intel.com/en-us/forums/intel-clusters-and-hpc-technology/topic/807359 and https://software.intel.com/en-us/forums/intel-clusters-and-hpc-technology/topic/812229.
As a workaround you can use legacy hydra process manager.
Please try to run `PATH=${I_MPI_ROOT}/intel64/bin/legacy:${PATH} mpiexec.hydra ...`

Hi Anatoliy:
Sorry to trouble you again, since the intel trace collector is running now, I think I got another issue now (should be a separate issue)
The intel tracer seems not able to stop, my program (OpenFOAM solver) stopped but the tracer seems to continue to run and writing files.
I change the VERBOSE=3 so that's what it shows in the log file before the program started running:

It keeps running hours after the program stopped and I assume something is nor right.

Hi, Chi.
Could you try to run with `export VT_KEEP_RAW_EVENTS=on` variable?

Hi Anatoliy:
Thanks for the reply, the same issue disappeared today. Maybe it is our side of mistake in some network setting or the OS update.
I'll update you if that happens again.
Again, your time spent on this subject help us a lot to understand how this software works.
Best wishes
Chi
