So this is what I got:
AMD Perfomance Counter Monitor
AMDuProfPcm is a command-line tool to monitor CPU performance metrics of AMD processors.
Usage: AMDuProfPcm [<OPTIONS>] -- <PROGRAM> [<ARGS>]
OPTIONS
-m <METRIC,..> Metrics to report.
Supported METRIC's are - <dc | fp | ipc | l1 | l2 | l3 | memory | tlb>
Note: These metrics are applicable only with the built-in config file.
-c <core|ccd|package=<n> Collect from the specified core | ccd | package. Default is 'core=0'.
If 'ccd' is specified:
core events will be collected from all the cores of this die.
l3 events will be collected from the first core of all the ccx's of this die.
df events will be collected from the first core of this die.
If 'package' is specified:
core events will be collected from all the cores of this package.
l3 events will be collected from the first core of all the ccx's of this package.
df events will be collected from the first core of all the die's of this package.
-a Collect from all the cores. Note: Options -c and -a cannot be used together.
-i <config file> User defined XML config file that specifies Core|L3|DF counters to monitor.
Refer sample files at <install-dir>/bin/Data/Config/ dir for the format.
Note: Options -i and -m cannot be used together. If option -i is used, all the events
mentioned in the user-defined config file will be collected.
-d <seconds> Profile duration to run.
-t <multiplex interval in ms> Interval in which pmc count values will be read. Minimum is 16ms.
-k Prefix 'pkg' in package level counters. Available only for package level counters
-o <output file> Output file name.
-D <dump file> Output file that contains the event count dump.
-p <n> Set precision of the metrics reported. Default is 2.
-q Hide CPU topology reported.
-r To force reset the MSRs.
-s Display time stamp in the time series report
-I <ms> Prints the metrics at regular interval. Enabled by default with 1000ms interval
-C Prints the cumulative metrics at the end of the profile duration. Otherwise, all the
samples will be reported as timeseries data.
-A <system,package,ccd,core>
Prints aggregated metrics at specified component level
-l List supported Raw PMU events.
-z <pmc-event> Print the name, description and available unit masks for the event.
-x <core-id,..> Core affinity for launched application. Comma separated list of core-id's.
-w <dir> Specify the working directory. Default will be the path of the launched application.
-n Print cpu numa topology.
-v Print version.
-h Print help.
PROGRAM The application to be launched before collecting the profile data.
ARGS The list of arguments for the launch application.
*** pre-release features ***
MONITORING WITHOUT ROOT PRIVILEGES:
The pre-release option -X can be used to monitor the metrics without having the dependency on "msr" module and root access.
This option can be used to collect Core, L3 and DF PMC events on Zen based processors. Newer proceesors may require
latest kernels supporting those newer processor models.
EXAMPLES:
Timeseries monitoring of ipc of a benchmark. Aggregate metrics per thread.
$ AMDuProfPcm -X -m ipc -o /tmp/pcm.csv -- AMDTClassicMatMul-bin
Timeseries monitoring of ipc of a benchmark. Aggregate metrics per processor package.
$ AMDuProfPcm -X -m ipc -A package -o /tmp/pcm.csv -- AMDTClassicMatMul-bin
Timeseries monitoring of ipc of a benchmark. Aggregate metrics at the system level.
$ AMDuProfPcm -X -m ipc -A system -o /tmp/pcm.csv -- AMDTClassicMatMul-bin
Cumulative reporting of ipc metrics at the end of the benchmark execution.
$ AMDuProfPcm -X -m ipc -C -o /tmp/pcm.csv -- AMDTClassicMatMul-bin
Cumulative reporting of ipc metrics at the end of the benchmark execution. Aggregate metrics per processor package.
$ AMDuProfPcm -X -m ipc -C -A package -o /tmp/pcm.csv -- AMDTClassicMatMul-bin
Cumulative reporting of ipc metrics at the end of the benchmark execution. Aggregate metrics at system level.
$ AMDuProfPcm -X -m ipc -C -A system -o /tmp/pcm.csv -- AMDTClassicMatMul-bin
Timeseries monitoring of memory bandwidth reporting at package and memory channels level.
$ AMDuProfPcm -X -m memory -a -A system,package -o /tmp/mem.csv
Timeseries monitoring of level 1 and level 2 topdown metrics (pipeline utilization)
$ AMDuProfPcm -X -m topdown -A system -o /tmp/td.csv -- AMDTClassicMatMul-bin
Cumulative reporting of level 1 and level 2 topdown metrics (pipeline utilization)
$ AMDuProfPcm -X -m topdown -C -A system -o /tmp/td.csv -- AMDTClassicMatMul-bin
For better topdown results disable NMI watchdog. As root, run "echo 0 > /proc/sys/kernel/nmi_watchdog"
ROOFLINE MODEL:
An easy to visualize performance model that can be used to characterize a benchmark or application on an architecture.
This performance model helps to identify whether a benchmark is memory-bound or compute-bound.
Following steps can be used to generate a roofline graph of an application.
To collect profile data
# AMDuProfPcm roofline -o /tmp/myapp-rl.csv -- <PROGRAM> [<ARGS>]
To collect data in non-root mode
$ AMDuProfPcm roofline -X -o /tmp/myapp-rl.csv -- <PROGRAM> [<ARGS>]
To plot roofline
$ AMDuProfModelling.py -i /tmp/myapp-rl.csv -o /tmp/
The above command will generate the roofline plot in a PDF file and save it in /tmp/ dir.
Run "AMDuProfModelling.py -h" for the options supported by this script.
********
EXAMPLES:
1. Run the command and collect ipc performance metrics and print in regular interval (1000ms) in console
# AMDuProfPcm -m ipc -c core=0 -- /usr/bin/taskset -c 0 AMDTClassicMatMul-bin
2. Collect ipc metrics from core 0 for duration of 10 seconds and in regular interval save profile data in a file
# AMDuProfPcm -m ipc -c core=0 -d 10 -o /tmp/perf-overview.csv
3. Collect memory bandwidth for all the memory channels and save the profile data in a file
# AMDuProfPcm -m memory -a -d 10 -o /tmp/perf-overview.csv
