gem5-aladdin's Issues

Compiltation error

On running command scons ./build/RISCV/gem5.debug i get following compilation error!

Xenon sweep scripts should be updated to always run with a cpu

Several issues in one here:

1. Xenon sweep scripts currently default to set simulator "gem5-cache", for an accelerator-only simulation. This feature has been deprecated. All scripts should be updated to set simulator "gem5-cpu".
2. Xenon sweep scripts need to add generate gem5_binary so that the benchmarks get built.
3. We removed the hyphens from the Machsuite benchmark names (issue #6). This now conflicts with the names of the benchmarks in their Makefiles, which still contain the hyphens. This needs to be updated too, along with any other references.

Checking ISA Word Length

On line 622 of syscall_emul.cc, it looks like you're trying to get the ISA's word size? It might be better to just say size_t word_size = sizeof(Addr); instead of explicitly checking for ISA, since the size of an address should be the size of a word (actually you can probably entirely replace word_size with sizeof(Addr)). I think this will make gem5-Aladdin entirely ISA-independent, since I only had to change that to make it compatible with RISC-V.

compilation error in the docker image

Hello,

I am trying to compile a gem5 in the docker image but it is unsuccessful. My workflow is as follows:

Getting the docker image and accessing it:

docker pull xyzsam/gem5-aladdin
docker run -it --rm --mount source=gem5-aladdin-workspace,target=/workspace xyzsam/gem5-aladdin

Updating submodules and aladdin

cd /workspace/gem5-aladdin/; git pull; git submodule update --init --recursive
cd /workspace/gem5-aladdin/src/aladdin; git pull origin master

Finally compiling gem5:

cd /workspace/gem5-aladdin/; scons build/X86/gem5.opt

First it asks about the missing hook

scons: Reading SConscript files ...

You're missing the gem5 style or commit message hook. These hooks help
to ensure that your code follows gem5's style rules on git commit.
This script will now install the hook in your .git/hooks/ directory.
Press enter to continue, or ctrl-c to abort:

Then it fails with the following message:

{standard input}: Assembler messages:

Any help would be much appreciated,

Tomas

MachSuite and SHOC benchmarks are still using DMA interface v1

DMA interface v1 is deprecated. All benchmarks should be migrated to v3. The primary difference is that now there is an explicit separation between host memory and accelerator memory, rather than the implicit difference in the past.

visualization of the DDDG.

Is there any tool to visualize the DDDG?

Disable performance, power, or area

Is there a way to control

2. Power and area only

CPU clock doesn't get set right

I have written about this in the gem5-aladdin group some time ago but configs/aladdin/aladdin_se.py needs some further configuration to set the CPU clock correctly or CPU will be set at system clock.

You need to add:

# All cpus belong to a common cpu_clk_domain, therefore running at a common     
# frequency.                                                           
for cpu in system.cpu:    
    cpu.clk_domain = system.cpu_clk_domain

I have put it at line 333 since gem5 puts it there, but I think is fine anywhere.

Compilation Error

When I try to compile gem5 using
scons buid/X86/gem5.opt
I get this error
ImportError: cannot import name MemTraceProbe

can we execute deep RL maddpg -pytorch algorithm on gem5-aladdin

Hello,
I'm trying to execute maddpg https://github.com/shariqiqbal2810/maddpg-pytorch on an architecture simulator. So, I'm looking around for various applications. I wanted to ask if I can simulate maddpg on gem5-Aladdin?
Note: maddpg uses in python 3.6

Regarding PE's configuration

When accelerator type is set to aladdin then does it imply a certain configuration of how the PE's are arranged? If I wish to change the number of PE's, say 16 in a 4x4 grid each with 8 vector MAC units then how can I configure this?
For this,
in smv_convolution_op.cpp
const int kNumPEs = 16;
const int kNumMaccsPerPE = 64? cause originally it was 32 (assuming 4 NUM_MACC_INSTS x 8)
and in params.h
#define NUM_MACC_INSTS 8
#define NUM_PE_INSTS 16

but making these changes hardly brought a change in the stats files

Also if I want to change word width, by reducing the bits (10 or 8 bits ) in which data can be stored and communicated will changing the smv-accel.cfg be fine? Where else will I have to make changes? ( will this be feasible or only fp16 and fp32 work? )

Thank you.

How to build gem5 on Linux?

How to build gem5 on Linux? In my case, it is in Secure zone with default Python 2.7.

Error: can't find library python2.7

Hi,
I am getting the following error in the latest gem5-aladdin image downloaded from docker.
Error: can't find library python2.7. In the scons_config.log, it states the following:
/usr/bin/ld: cannot find -lboost_regex
collect2: error: ld returned 1 exit status
Am I doing something wrong here? I ran the following command
which python2.7 which scons build/X86/gem5.opt
Also, I am able to build gem5 on the same machine.

panic: invalid stat name 'system.aes-aes_datapath.tlb.hits'

I can create the config files (aladdin/gem5-cache/gem5-cpu)and compile the simulator. However, when I run the run.sh file I have 2 problems. First, I need to change the cpu-type from timing to DerivedO3 and memory type from DDR3_1600 to something else because they are not longer supported. Then, if I run the simulator I get this error:
panic: invalid stat name 'system.aes-aes_datapath.tlb.hits'
And then simulation is terminated.
Any idea?
Thanks

Error when running test_multiple_accelerators example with default settings

I ran the default run.sh script for test_multiple_accelerators example and got the following error:

root@ed4c7a3ad50b:/workspace/gem5-aladdin/src/aladdin/integration-test/with-cpu/test_multiple_accelerators# sh run.sh 
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "build/X86/python/m5/main.py", line 468, in main
  File "/workspace/gem5-aladdin/src/aladdin/../../configs/aladdin/aladdin_se.py", line 398, in <module>
    system.find_all(SystolicArray)[0]) == len(system.ruby._cpu_ports))
AssertionError

On investigating further, I found the assertion error is due to "ruby" option in run.sh.

The failing assertion was:
assert(options.num_cpus + 3*len(system.find_all(HybridDatapath)[0] + \ system.find_all(SystolicArray)[0]) == len(system.ruby._cpu_ports))

I printed the str(arg) of each of the arguments in the assertion. These are the values.
str(options.num_cpus) = 1, str(len(system.find_all(HybridDatapath)[0]) ) = 4, str (system.find_all(SystolicArray)[0]) ) = [], str (len(system.ruby._cpu_ports) ) = 1
Hope this helps. Also, can you comment why len(system.ruby._cpu_ports) equals 1 ?

Thanks,
Isaar

error while loading shared libraries: libprotobuf.so.9: cannot open shared object file: No such file or directory

Hi Sam,

I am getting the following error with the latest version of gem5-Aladdin docker file:

Please suggest what needs to be done.

Thanks in advance.

Error: can't find library python2.7 required by python

Hi,

I am getting this error while compiling the source:
Error: can't find library python2.7 required by python
I have Python2.7 and Python-dev,a nd SQLlite installed. I can compile the latest version of gem5 on my machine, but I cannot install aladdin.

SCons and python3 issues

gem5 has not yet fully migrated to Python3, but the version of Scons we use in the docker image has, which causes issues like this if the user just runs scons build/X86/gem5.opt:

TypeError: a bytes-like object is required, not 'str':
  File "/workspace/gem5-aladdin/SConstruct", line 393:
    main['GCC'] = CXX_version and (CXX_version.find('g++') >= 0 or \

For now, a workaround is to use the command: python2.7 `which scons` build/X86/gem5.opt.

Questions about the support of fully-coherent caches in gem5-Aladdin

Hello. It is said in the readme file that gem5-Aladdin supports three coherence models: non-coherent DMA, LLC-coherent directly access (using ACP), and fully-coherent caches. Meanwhile, in the integration test 'test_load_store', the accelerator uses the private cache to access data from the main memory.
(1) Does the 'test_load_store' test belong to the so-called 'fully-coherent caches' model?

In my mind, fully-coherent caches mean that the accelerator's private cache should be coherent with the cpu's private cache (maybe they should be both connected to a shared L2 cache with a coherence protocol).
(2) However, gem5-Aladdin directly connects the accelerator's private cache to the membus by default, and how can it be coherent with the cpu's L1 cache?

Then, I have tried to add an L2 cache in 'test_load_store' and modify the aladdin_se.py to re-connect the accelerator's private cache to the L2 cache, making the L2 shared by both the accelerator's and cpu's privated caches. The simulation result seems to make sense, but I don't know whether it is correct. Meanwhile, I find an annotation in lines 248-251 of configs/common/CacheConfig.py

gem5-aladdin/configs/common/CacheConfig.py

Line 248 in d4efbee

# The ability for the accelerator to have an L2 cache has been removed

:

• # The ability for the accelerator to have an L2 cache has been removed for now. The original implementation of attaching the accelerator's dcache to the CPU's L2 cache is probably not what users would expect anyways.

(3) I wonder what does the authors mean by this annotation.
(4) What does the real 'fully-coherent caches' mean in gem5-Aladdin?

Systolic arrays sizes

I am testing the systolic array accelerator, and I am having problems when changing the array sizes. For the default configuration (8x8), everything works fine.

For smaller sizes, it never ends. It gets stuck in a loop, and never leaves. The following is an example of a loop for a 4x4 systolic array. This happens even for the base test.c.

As for the bigger SAs, there are two cases. In the base test.c, SAs up to a size of 16 (not included) work as expected. For bigger sizes, I am getting a segmentation fault.

If I want to simulate bigger layers (e.g., ResNet's conv3), for bigger SAs I am getting the following error:

fatal: Streaming out premature data!

How can these errors be fixed?

GEMM in Systolic Array

Is there currently a way to compute matrix-matrix multiplications with the systolic array or is it limited to convolutional tensors?

Can we simulate 8-bit integer by using Gem5-Aladdin?

Hi.
As the title. I wonder can we make the simulation with datawidth=1byte (8bits). such as 8-bit fixed-point. and system_bus =32 or 64 bits?

Overlapping array address ranges can lead to incorrect behavior, such as DMA nodes trying to access the wrong arrays, ACP accessing the wrong memory, etc. Please check your Aladdin configuration file and the mapArrayToAccelerator() calls to verify that they are correct.
Global loop pipelining is not ON.
 Current power model supports trig functions running at 10 ns. 
 Cycle time: 2 is not supported yet. Use 10ns power model instead.

How to reproduce

1. get docker from docker pub
2. docker run image
3. python2.7 `which scons` build/X86/gem5.opt

Error while generating sweeps

Hello,
I'm discovering Aladdin and Gem5-aladdin, and I'd like to try some examples from the SHOC benchmark suite. The example provided in https://github.com/ysshao/ALADDIN cites the SHOC/triadexample. So I'd like to generate other configurations using Xenon.

For shoc.xe and machsuite.xe I get the following error, did I miss something in my way?
(I also mention that cortexsuite is not in the repo).

Thanks for the help!
Best regards,

SHOC/fft dynamic trace issue

Hi,
I was trying to run the fft test in SHOC. In the normal mode (without dma) it makes the dynamic trace but it does not give out the power and area summary (it does give out the stats). When I try to make the trace using the dma-trace-binary, the fft-instrumented has a segmentation fault. Please let me know if there is a workaround. My main goal is to get power and area numbers.

Thanks

For each algorithm of MachSuite, how to generate the corresponding executable file and the necessary files configured in gem.5.cfg such as dynamic_trace.gz?

For each algorithm of MachSuite, how to generate the corresponding executable file and the necessary files configured in gem.5.cfg such as dynamic_trace.gz?
For example, I want to simulate the test_aes to experiment on the gemm algorithm. Which files are necessary, how are they generated, which are generated by tools, and which need to be manually configured by themselves?

Is gem5-aladdin okay in simulating systolic arrays?

I hope that systolic array is not a strange name nowadays. I see a lot of custom accelerators (like TPU) use systolic array as very crucial part in their design. Therefore, I wonder is Gem5-Aladdin eligible to build such a systolic array-based accelerator? And then fetching data from surrounding buffer to feed into this accelerator as a specific dataflow?

Of course, my final target is interaction analysis between this accelerator and surrounding component, not internal NoC issues...
