caldgemm with HD6990s

Can I run caldgemm on HD6990s?

Hi,

I am sorry that I cannot find the caldgemm forum so I post here and hopefully its developers read this message.

I have 4 HD6990s and I really like to see how they perform in GFLOPs, so I come across this tool, http://code.compeng.uni-frankfurt.de/projects/caldgemm/wiki

I have Ubuntu 10.10 x86_64 + AMD driver 11.5 + SDK 2.4 and I followed the instructions on the wiki, however I have to add "make TARGET=NEHALEM NO_MEMPOLICY=1 -j" in order to compile GotoBLAS2 since I have two E5620 CPUs.

I compile caldgemm, its outputs look fine.

But If I run it, it prompts error and hangs idle, can anyone help? Thanks!

There currently is no forum for caldgemm, however there is a (low volume) mailing list at https://compeng.uni-frankfurt.de/mailman/listinfo/caldgemm .

What I can see from your output ist the following:

  • Use -z if you want to use both GPUs.
  • Memory allocation fails. I assume your ulimit for max locked memory is too low. For machines on which you want to benchmark it makes sense to set "ulimit -l unlimited". You might also want to specify that in /etc/security/limits.conf.

Hi Marix,

if I do

rolly@rolly-X8DTG-QF:~$ ulimit -a
core file size          (blocks, -c) unlimited
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 20
file size               (blocks, -f) unlimited
pending signals                 (-i) 16382
max locked memory       (kbytes, -l) 64
max memory size         (kbytes, -m) unlimited
open files                      (-n) 1024
pipe size            (512 bytes, -p) 8
POSIX message queues     (bytes, -q) 819200
real-time priority              (-r) 0
stack size              (kbytes, -s) unlimited
cpu time               (seconds, -t) unlimited
max user processes              (-u) unlimited
virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited

So I made some change to /etc/security/limits.conf

http://www.akadia.com/services/ora_enable_core.html

now I can change ulimit -l unlimited and it looks like

rolly@rolly-X8DTG-QF:~/caldgemm$ ulimit -a
core file size          (blocks, -c) unlimited
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 20
file size               (blocks, -f) unlimited
pending signals                 (-i) 16382
max locked memory       (kbytes, -l) unlimited
max memory size         (kbytes, -m) unlimited
open files                      (-n) 1024
pipe size            (512 bytes, -p) 8
POSIX message queues     (bytes, -q) 819200
real-time priority              (-r) 0
stack size              (kbytes, -s) unlimited
cpu time               (seconds, -t) unlimited
max user processes              (-u) unlimited
virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited

Now running benchmark,

Any hint on the last error? Thank you!

HI Marix,

Further update to my problem, I think this is due to multiple GPU issues. I did the same for another system with same software config but just a single HD6970, it nnow produce the reasonable results:

Is this true that the system performance just 164 GFLOPS vs kernel 465 GFLOPS for a single GPU HD6970.

For my 4x HD6990s, the -g parameter does not work at all...

Thanks!

Regarding the low system performance. There is currently a known performance issue with all HD6000 series devices. It can be tuned around and there is a new version with some proper workarounds in the queue. However the copy speeds look aktually quite good in your case. Your matrix size is, however, rather small. Why you should get quite some performance at that size it would be interesting to see what you can reach at 20k or even 40k for m and n (k may stay at 1024).

Hi Marix, thanks for your info, I rerun the test this time on the single HD6970 with 4GB host memory, so I can only run m=n=16384.

Please have a look at the output., the best I get is 212 GFLOPS. Thank you

Hi rollyng,

as marix said there is an issue related to 6000 series GPU that decreases system performance dramatically. However, the -z parameter should actually work.

to help debugging this problem can you do the following:

activate the DEBUG_MSG_ALLOCATION swith in caldgemm_config.h

set the STD_OUT parameter to stderr in caldgemm_config.h

run dgemm_bench -g -z -v -d and paste the output.

can you please also tell me exactly which version you are using?

Cheers

Finally -z for GPUs. To me the -z option does not work at all?

By the way, I just "git clone git://code.compeng.uni-frankfurt.de/caldgemm", am I having the latest version of caldgemm?

Thanks!

Hi rollyng,

I tried to look into this, I plugged three 6970 GPUs in a node but I cannot reproduce the issue you see.

The log you posted tells me that the AMD runtime is unable to allocate host memory, i.e. I issue a malloc call for a page locked buffer but get an error message.

Could you plase update to the current git revision or apply the attached patch. The debug message will then provide the error code of the API which is needed to analyze this further.

As you said your system only has 4GB of memory you might be running out of page locked memory.

you can try to use two GPUs and see whether that works with: ./dgemm_bench -z -v -d -Y 2

 

Regards

HI, I recompiles the lastest with git pull,

with -c -z -d now it gives output:

I think caldgemm currently requires 2 to 3 CPU-Cores per GPU (would have to check the source), so yes, on your CPUs it probably won't be able to support more than two 6990s.

This is to some extend owed to the fact that we currently use Magny-Cours-CPUs  -> Plenty of cores.

is there any place where i can see a performance comparison between caldgemm and clAmdBlasDgemm ?

However, as I run this time_dgemm.exe, it looks like I am hitting the same wall, it just can make use of 3 out of 8 GPUs... but I have 32GB of host memory?

Hi, I did some test with acmlgpu1.1.2. as I run the Info.exe, it shows

 

hi there, what's the difference between ACML-GPU and clAmdBlas? Would it be that one is CAL and the other OpenCL? And what about performance (at least for single GPU setup)?

0 Likes

Hi, I think you are right. clAmdBlas needs OpenCL but I find that there is only sgemm example for clAmdBlas, so I may not be able to compare dgemm performance of the two libraries?

0 Likes

yes, there's only the sgemm example (but be aware that this example has a typo fault - matrix A is written to the bufB - check this post http://forums.amd.com/devforum/messageview.cfm?catid=390&threadid=150952&enterthread=y), but, well, they perform exactly the same mathematical operations except for the data type (double instead of float), so I believe you can use the exact same example changing the types only and having a card that supports double precision computations (like the 6790 of yours).

if you comprare performance results with caldgemm, please let us know.

OK, let's have the acmlgpu-1.1.2 first for both dgemm and sgemm on single HD6970.

What I can conclude so far:

(1) Only 1 HD6990 can only run on these libraries no matter how many extra of these are installed?

(2) acml-gpu looks having batter performance?

Thanks for reading!

0 Likes

(1) You mean 1 HD6970, right? Well, it seems to be it, since the performance is roughly 1/5 of the nominal TERAFLOP number in the best of the two libraries. Can anyone confirm this?

(2) There's something I didn't understand. Is the matrices size for acmlgpu-1.1.2 equal to 8000x8000? Because caldgemm do the product for 8192x1024, which is a huge difference. Since the size of the matrix has a visible influence on the Gflops, we can hardly compare these results. Could you re-run them for comparable matrix sizes? However, I don't know if the algorithm is optimized for square matrices or not. 

And, if you have a little more of time, could you test the clAmdBlasDegmm (and maybe clAmdBlasSegmm to compare to time_sgemm.exe)?

Originally posted by: Marix I think caldgemm currently requires 2 to 3 CPU-Cores per GPU (would have to check the source), so yes, on your CPUs it probably won't be able to support more than two 6990s.

 

This is to some extend owed to the fact that we currently use Magny-Cours-CPUs  -> Plenty of cores.

 

Hi Marix, thanks for your clarification, I have 2 E5620 on my system with Hyperthread enabled, so system monitor shows 16 CPUs and I should have 2 CPUs per Cayman GPU. Is this still insufficient for the caldgemm requirement? I believed the max CPU cores per node is 24 with Intel 1366 pin processors, so that makes 3 CPUs per Cayman...

I am having similar memory issues.  I am running an HD5870.  I tried following the instructions given on the Wiki.

Here are things I ddi not do:

Instead of using git, I just downloaded/unzipped the latest version from the Files Page

-march=native didn't work so I just deleted it from makefile so that it can compile error-free.

I did not use the binary patch for the Catalyst driver.

 

Here is my output given your instructions of ./dgemm_bench -g -z -v -d
