Re: [Ganglia-general] Gmond Compilation on Cygwin
Thanks for the updates Peter and Bernard. I have been unable to get gmond 3.4 working under Cygwin, my latest errors are parsing gm_protocol_xdr.c. I don't know whether we should follow this up, it would be nice to have a Windows gmond, but my only reason for upgrading are the GPU metrics. I take you point about re-using the existing GPU module and gmetric, unfortunately I don't have experience with Python. My plan is to write something in C to export the nvml metrics, with various output options. We will then decide whether to call this new code from existing gmond 3.1 via gmetric, new (if we get it working) gmond 3.4, or one of our existing third party tools - ITRS Geneous.

Re: [Ganglia-general] Gmond Compilation on Cygwin
Hi Robert,
sFlow is a very simple protocol - an sFlow agent periodically sends
XDR encoded structures over UDP. Each structure has a tag and a
length, making the protocol extensible.
In the short term, it would make sense is to define an sFlow structure
to carry the current NVML metrics and tag it using NVIDIA's IANA
assigned vendor number (5703). Something along the lines:
/* NVML statistics */
/* opaque = counter_data; enterprise = 5703, format=1 */
struct nvml_gpu_counters {
unsigned int device_count;
unsigned int mem_total;
unsigned int mem_util;
...
}
Additional examples are in the sFlow Host Structures specification
(http://www.sflow.org/sflow_host.txt), these are the structures
currently being exported by the Host sFlow agent.
Extending the Windows Host sFlow agent to export these metrics would
involve adding a routine to populate and serialize this structure -
pretty straightforward - if you look at the Host sFlow agent source
code you will see examples of how the existing structures are handled.
For Ganglia to support the new counters, we would need to add a
decoder to gmond for the new structure - also straightforward.
Are per device metrics important, or can we roll up the metrics across
all the GPUs on a server? With sFlow we generally roll up metrics for
each node where possible - the goal is to provide enough detail so
that the operations team can tell whether a node is healthy or not,
but not so much as to overwhelm the monitoring system and limit
scaleability. Once a problem is detected, detailed metrics for
troubleshooting and diagnostics can be performed using point tools on
the host.
The metrics currently exposed by NVML API could be improved -
everything appears to be a 1 second gauge. A more robust model for
metrics is to maintain monotonic counters so that they can be polled
at different frequencies and still produce meaningful results.
Counters are also more robust when sending metrics over an unreliable
transport like UDP. The receiver calculates the delta's and can easily
compensate for lost packets.
Longer term it would be useful to have a discussion to see what
metrics best characterize operational performance and are feasible to
implement. Counters such as number of threads started, number of busy
ticks, number of idle ticks etc. are the type of measurement you want
to calculate utilizations. Some kind of load average based on the
thread run queue would also be interesting.
My calendar is pretty open next week - I am based in San Francisco, so
8am-5pm PST works best.

Hey,
A meeting may be a good idea. My schedule is mostly open next week. When
are others free? I will brush up on sflow by then.
NVML and the Python metric module are tested at NVIDIA on Windows and Linux,
but not within Cygwin. The process will be easier/faster on the NVML side if
we keep Cygwin out of the loop.

Hi Nigel:
Technically you only need 3.1 gmond to have support for the Python metric
module. But I'm not sure whether we have ever tested this under Windows.
Peter and Robert: How quickly can we get hsflowd to support GPU metrics
collection internally? Should we setup a meeting to discuss this?

Hi all,
Maybe it will be interesting. Some time ago I successfully compiled gmond
3.0.7 and 3.1.2 under Cygwin. If you need it I can upload somewhere gmond
and 3rd party sources + compilation script.
Also, I have gmetad 3.0.7 compiled for Windows. In additional, I developed
(just for fun) my implementation of gmetad 3.1.2 using .NET and C#.
P. S. I do not know whether it is possible to use these gmong versions to
collect statistic from GPU.

Re: [Ganglia-general] Gmond Compilation on Cygwin
Nigel, A simple option would be to use Host sFlow agents to export the core metrics from your Windows servers and use gmetric to send add the GPU metrics. You could combine code from the python GPU module and gmetric implementations to produce a self contained script for exporting GPU metrics: https://github.com/ganglia/gmond_python_modules/tree/master/gpu/nvidia https://github.com/ganglia/ganglia_contrib Longer term, it would make sense to extend Host sFlow to use the C-based NVML API to extract and export metrics. This would be straightforward - the Host sFlow agent uses native C APIs on the platforms it supports to extract metrics. What would take some thought is developing standard set of summary metrics to characterize GPU performance. Once the set of metrics is agreed on, then adding them to the sFlow agent is pretty trivial. Currently the Ganglia python module exports the following metrics - are they the right set? Anything missing? It would be great to get involvement from the broader Ganglia community to capture best practice from anyone running large GPU clusters, as well as getting input from NVIDIA about the key metrics. * gpu_num * gpu_driver * gpu_type * gpu_uuid * gpu_pci_id * gpu_mem_total * gpu_graphics_speed * gpu_sm_speed * gpu_mem_speed * gpu_max_graphics_speed * gpu_max_sm_speed * gpu_max_mem_speed * gpu_temp * gpu_util * gpu_mem_util * gpu_mem_used * gpu_fan * gpu_power_usage * gpu_perf_state * gpu_ecc_mode As far as scalability is concerned, you should find that moving to sFlow as the measurement transport reduces network traffic since all the metrics for a node are transported in a single UDP datagram (rather than a datagram per metric when using gmond as the agent). The other consideration is that sFlow is unicast, so if you are using a multicast Ganglia setup then this involves re-structuring your a configuration. You still need to have at least one gmond instance, but it acts as an sFlow aggregator and is mute: http://blog.sflow.com/2011/07/ganglia-32-released.html Peter On Tue, Jul 10, 2012 at 8:36 AM, Nigel LEACH nigel.le...@uk.bnpparibas.com wrote: Hello Bernard, I was coming to that conclusion, I’ve been trying to compile on various combinations of Cygwin, Windows, Hardware this afternoon, but without success yet.

Hey Nigel, I would be happy to help where I can. I think Peter's approach is a good start. We are updating the Ganglia plug-in with a few more metrics. My dev branch on github has some updates not yet in the trunk. https://github.com/ralexander/gmond_python_modules/tree/master/gpu/nvidia In terms of metrics, I can help explain what each means. I expect the usefulness of each to vary based on installation, so hopefully others can contribute their thoughts. * gpu_num - Useful indirectly. * gpu_driver - Useful when different machines may have different installed driver versions. * gpu_type - Marketing name of the GPU. * gpu_uuid - Globally unique immutable ID for the GPU chip. This is the NVIDIA preferred identifier when SW interfaces with a GPU. On a multi GPU board, each GPU has a unique UUID. * gpu_pci_id - What the GPU looks like on the PCI bus ID. + gpu_serial - For Tesla GPUs there is a serial number printed on the board. Note, that when there are multiple GPU chips on a single board, they share a common board serial number. When a human needs to grab a particular board, this number works well. * gpu_mem_total * gpu_mem_used Useful for high level application profiling. * gpu_graphics_speed + gpu_max_graphics_speed * gpu_sm_speed + gpu_max_sm_speed * gpu_mem_speed + gpu_max_mem_speed These are various clock speeds. Faster clocks - higher performance. * gpu_perf_state Similar to CPU pstates. P0 is the fastest performance. When pstate is P0 clock speeds and PCIe bandwidth can be reduced. * gpu_util * gpu_mem_util % of time when the GPU SM or GPU memory was busy over the last second This is a very coarse grain way to monitor GPU usage. I.E. If only one SM is busy, but it is busy for the entire second then gpu_util = 100 * gpu_fan * gpu_temp Some GPUs support these. Useful to see how well the GPU is cooled. * gpu_power_usage + gpu_power_man_mode + gpu_power_man_limit GPU power draw. Some GPUs support configurable power limits via power management mode. * gpu_ecc_mode Useful to ensure all GPUs are configured the same. Describes if GPU memory error checking and correction is on or off. If you are only concerned about coarse grained GPU performance, then GPU performance state, utilization and %memory used may work well. Bernard, thanks for the heads up.

Thanks, Bernard On Tue, Jul 10, 2012 at 12:06 PM, Peter Phaal peter.ph...@gmail.com wrote: Nigel, A simple option would be to use Host sFlow agents to export the core metrics from your Windows servers and use gmetric to send add the GPU metrics. You could combine code from the python GPU module and gmetric implementations to produce a self contained script for exporting GPU metrics: https://github.com/ganglia/gmond_python_modules/tree/master/gpu/nvidia https://github.com/ganglia/ganglia_contrib Longer term, it would make sense to extend Host sFlow to use the C-based NVML API to extract and export metrics. This would be straightforward - the Host sFlow agent uses native C APIs on the platforms it supports to extract metrics. What would take some thought is developing standard set of summary metrics to characterize GPU performance. Once the set of metrics is agreed on, then adding them to the sFlow agent is pretty trivial. Currently the Ganglia python module exports the following metrics - are they the right set? Anything missing? It would be great to get involvement from the broader Ganglia community to capture best practice from anyone running large GPU clusters, as well as getting input from NVIDIA about the key metrics. * gpu_num * gpu_driver * gpu_type * gpu_uuid * gpu_pci_id * gpu_mem_total * gpu_graphics_speed * gpu_sm_speed * gpu_mem_speed * gpu_max_graphics_speed * gpu_max_sm_speed * gpu_max_mem_speed * gpu_temp * gpu_util * gpu_mem_util * gpu_mem_used * gpu_fan * gpu_power_usage * gpu_perf_state * gpu_ecc_mode As far as scalability is concerned, you should find that moving to sFlow as the measurement transport reduces network traffic since all the metrics for a node are transported in a single UDP datagram (rather than a datagram per metric when using gmond as the agent). The other consideration is that sFlow is unicast, so if you are using a multicast Ganglia setup then this involves re-structuring your a configuration. You still need to have at least one gmond instance, but it acts as an sFlow aggregator and is mute: http

Re: [Ganglia-general] Gmond Compilation on Cygwin
You could try adding --disable-sflow as another configure option. (Or were you planning to use sFlow agents such as hsflowd?).
