Overview

cuSignal

The RAPIDS cuSignal project leverages CuPy, Numba, and the RAPIDS ecosystem for GPU accelerated signal processing. In some cases, cuSignal is a direct port of Scipy Signal to leverage GPU compute resources via CuPy but also contains Numba CUDA and Raw CuPy CUDA kernels for additional speedups for selected functions. cuSignal achieves its best gains on large signals and compute intensive functions but stresses online processing with zero-copy memory (pinned, mapped) between CPU and GPU.

NOTE: For the latest stable README.md ensure you are on the latest branch.

Quick Start

cuSignal has an API that mimics SciPy Signal. In depth functionality is displayed in the notebooks section of the repo, but let's examine the workflow for Polyphase Resampling under multiple scenarios:

Scipy Signal (CPU)

import numpy as np
from scipy import signal

start = 0
stop = 10
num_samps = int(1e8)
resample_up = 2
resample_down = 3

cx = np.linspace(start, stop, num_samps, endpoint=False) 
cy = np.cos(-cx**2/6.0)

%%timeit
cf = signal.resample_poly(cy, resample_up, resample_down, window=('kaiser', 0.5))

This code executes on 2x Xeon E5-2600 in 2.36 sec.

cuSignal with Data Generated on the GPU with CuPy

import cupy as cp
import cusignal

start = 0
stop = 10
num_samps = int(1e8)
resample_up = 2
resample_down = 3

gx = cp.linspace(start, stop, num_samps, endpoint=False) 
gy = cp.cos(-gx**2/6.0)

%%timeit
gf = cusignal.resample_poly(gy, resample_up, resample_down, window=('kaiser', 0.5))

This code executes on an NVIDIA V100 in 13.8 ms, a 170x increase over SciPy Signal

cuSignal with Data Generated on the CPU with Mapped, Pinned (zero-copy) Memory

import cupy as cp
import numpy as np
import cusignal

start = 0
stop = 10
num_samps = int(1e8)
resample_up = 2
resample_down = 3

# Generate Data on CPU
cx = np.linspace(start, stop, num_samps, endpoint=False) 
cy = np.cos(-cx**2/6.0)

# Create shared memory between CPU and GPU and load with CPU signal (cy)
gpu_signal = cusignal.get_shared_mem(num_samps, dtype=np.float64)

%%time
# Move data to GPU/CPU shared buffer and run polyphase resampler
gpu_signal[:] = cy
gf = cusignal.resample_poly(gpu_signal, resample_up, resample_down, window=('kaiser', 0.5))

This code executes on an NVIDIA V100 in 174 ms.

cuSignal with Data Generated on the CPU and Copied to GPU [AVOID THIS FOR ONLINE SIGNAL PROCESSING]

import cupy as cp
import numpy as np
import cusignal

start = 0
stop = 10
num_samps = int(1e8)
resample_up = 2
resample_down = 3

# Generate Data on CPU
cx = np.linspace(start, stop, num_samps, endpoint=False) 
cy = np.cos(-cx**2/6.0)

%%time
gf = cusignal.resample_poly(cp.asarray(cy), resample_up, resample_down, window=('kaiser', 0.5))

This code executes on an NVIDIA V100 in 637 ms.

Documentation

The complete cuSignal API documentation including a complete list of functionality and examples can be found for both the Stable and Nightly (Experimental) releases.

cuSignal 0.17 API | cuSignal 0.18 Nightly

Installation

cuSignal has been tested on and supports all modern GPUs - from Maxwell to Ampere. While Anaconda is the preferred installation mechanism for cuSignal, developers and Jetson users should follow the source build instructions below. As of cuSignal 0.16, there isn't a cuSignal conda package for aarch64.

Conda, Linux OS

cuSignal can be installed with conda (Miniconda, or the full Anaconda distribution) from the rapidsai channel. If you're using a Jetson GPU, please follow the build instructions below

For cusignal version == 0.17:

For CUDA 10.1.2
conda install -c rapidsai -c nvidia -c numba -c conda-forge \
    cusignal=0.17 python=3.8 cudatoolkit=10.1

# or, for CUDA 10.2
conda install -c rapidsai -c nvidia -c numba -c conda-forge \
    cusignal=0.17 python=3.8 cudatoolkit=10.2

# or, for CUDA 11.0
conda install -c rapidsai -c nvidia -c numba -c conda-forge \
    cusignal=0.17 python=3.8 cudatoolkit=11.0

For the nightly verison of cusignal, currently 0.18a:

# For CUDA 10.1.2
conda install -c rapidsai-nightly -c nvidia -c numba -c conda-forge \
    cusignal python=3.8 cudatoolkit=10.1.2

# or, for CUDA 10.2
conda install -c rapidsai-nightly -c nvidia -c numba -c conda-forge \
    cusignal python=3.8 cudatoolkit=10.2

# or, for CUDA 11.0
conda install -c rapidsai-nightly -c nvidia -c numba -c conda-forge \
    cusignal python=3.8 cudatoolkit=11.0

cuSignal has been tested and confirmed to work with Python 3.6, 3.7, and 3.8.

See the Get RAPIDS version picker for more OS and version info.

Source, aarch64 (Jetson Nano, TK1, TX2, Xavier), Linux OS

In cuSignal 0.15 and beyond, we are moving our supported aarch64 Anaconda environment from conda4aarch64 to miniforge. Further, it's assumed that your Jetson device is running a current (>= 4.3) edition of JetPack and contains the CUDA Toolkit.

Clone the repository

# Set the location to cuSignal in an environment variable CUSIGNAL_HOME
export CUSIGNAL_HOME=$(pwd)/cusignal

# Download the cuSignal repo
git clone https://github.com/rapidsai/cusignal.git $CUSIGNAL_HOME

Install miniforge and create the cuSignal conda environment:
```
cd $CUSIGNAL_HOME
conda env create -f conda/environments/cusignal_jetson_base.yml
```
Note: Compilation and installation of CuPy can be quite lengthy (~30+ mins), particularly on the Jetson Nano. Please consider setting this environment variable to decrease the CuPy dependency install time:

export CUPY_NVCC_GENERATE_CODE="arch=compute_XX,code=sm_XX" with XX being your GPU's compute capability. If you'd like to compile to multiple architectures (e.g Nano and Xavier), concatenate the arch=... string with semicolins.
Activate conda environment

conda activate cusignal-dev

Install cuSignal module

cd $CUSIGNAL_HOME
./build.sh  # install cuSignal to $PREFIX if set, otherwise $CONDA_PREFIX
            # run ./build.sh -h to print the supported command line options.

Once installed, periodically update environment

cd $CUSIGNAL_HOME
conda env update -f conda/environments/cusignal_jetson_base.yml

Also, confirm unit testing via PyTest

cd $CUSIGNAL_HOME/python
pytest -v  # for verbose mode
pytest -v -k <function name>  # for more select testing

Source, Linux OS

Clone the repository

# Set the location to cuSignal in an environment variable CUSIGNAL_HOME
export CUSIGNAL_HOME=$(pwd)/cusignal

# Download the cuSignal repo
git clone https://github.com/rapidsai/cusignal.git $CUSIGNAL_HOME

Download and install Anaconda or Miniconda then create the cuSignal conda environment:

Base environment (core dependencies for cuSignal)
```
cd $CUSIGNAL_HOME
conda env create -f conda/environments/cusignal_base.yml
```
Full environment (including RAPIDS's cuDF, cuML, cuGraph, and PyTorch)
```
cd $CUSIGNAL_HOME
conda env create -f conda/environments/cusignal_full.yml
```
Activate conda environment

conda activate cusignal-dev

Install cuSignal module

cd $CUSIGNAL_HOME
./build.sh  # install cuSignal to $PREFIX if set, otherwise $CONDA_PREFIX
            # run ./build.sh -h to print the supported command line options.

Once installed, periodically update environment

cd $CUSIGNAL_HOME
conda env update -f conda/environments/cusignal_base.yml

Also, confirm unit testing via PyTest

cd $CUSIGNAL_HOME/python
pytest -v  # for verbose mode
pytest -v -k <function name>  # for more select testing

Source, Windows OS

We have confirmed that cuSignal successfully builds and runs on Windows by using CUDA on WSL. Please follow the instructions in the link to install WSL 2 and the associated CUDA drivers. You can then proceed to follow the cuSignal source build instructions, below.

Download and install Andaconda for Windows. In an Anaconda Prompt, navigate to your checkout of cuSignal.
Create cuSignal conda environment

conda create --name cusignal-dev
Activate conda environment

conda activate cusignal-dev
Install cuSignal Core Dependencies
```
conda install numpy numba scipy cudatoolkit pip
pip install cupy-cudaXXX
```
Where XXX is the version of the CUDA toolkit you have installed. 10.1, for example is cupy-cuda101. See the CuPy Documentation for information on getting Windows wheels for other versions of CUDA.
Install cuSignal module
```
./build.sh
```
[Optional] Run tests In the cuSignal top level directory:
```
pip install pytest
pytest
```

Docker - All RAPIDS Libraries, including cuSignal

For cusignal version == 0.16:

# For CUDA 11.0
docker pull rapidsai/rapidsai:cuda11.0-runtime-ubuntu18.04
docker run --gpus all --rm -it -p 8888:8888 -p 8787:8787 -p 8786:8786 \
    rapidsai/rapidsai:cuda11.0-runtime-ubuntu18.04

For the nightly version of cusignal

docker pull rapidsai/rapidsai-nightly:cuda11.0-runtime-ubuntu18.04
docker run --gpus all --rm -it -p 8888:8888 -p 8787:8787 -p 8786:8786 \
    rapidsai/rapidsai-nightly:cuda11.0-runtime-ubuntu18.04

Please see the RAPIDS Release Selector for more information on supported Python, Linux, and CUDA versions.

SDR Integration

SoapySDR is a "vendor neutral and platform independent" library for software-defined radio usage. When used in conjunction with device (SDR) specific modules, SoapySDR allows for easy command-and-control of radios from Python or C++. To install SoapySDR into an existing cuSignal Conda environment, run:

conda install -c conda-forge soapysdr

A full list of subsequent modules, specific to your SDR are listed here, but some common ones:

rtlsdr: conda install -c conda-forge soapysdr-module-rtlsdr
Pluto SDR: conda install -c conda-forge soapysdr-module-plutosdr
UHD: conda install -c conda-forge soapysdr-module-uhd

Another popular SDR library, specific to the rtl-sdr, is pyrtlsdr.

For examples using SoapySDR, pyrtlsdr, and cuSignal, please see the notebooks/sdr directory.

Please note, for most rtlsdr devices, you'll need to blacklist the libdvb driver in Linux. To do this, run sudo vi /etc/modprobe.d/blacklist.conf and add blacklist dvb_usb_rtl28xxu to the end of the file. Restart your computer upon completion.

If you have a SDR that isn't listed above (like the LimeSDR), don't worry! You can symbolically link the system-wide Python bindings installed via apt-get to the local conda environment. Please file an issue if you run into any problems.

Benchmarking

cuSignal uses pytest-benchmark to compare performance between CPU and GPU signal processing implementations. To run cuSignal's benchmark suite, navigate to the topmost python directory ($CUSIGNAL_HOME/python) and run:

pytest --benchmark-enable --benchmark-gpu-disable

Benchmarks are disabled by default in setup.cfg providing only test correctness checks.

As with the standard pytest tool, the user can use the -v and -k flags for verbose mode and to select a specific benchmark to run. When intrepreting the output, we recommend comparing the mean execution time reported.

To reduce columns in benchmark result's table, add --benchmark-columns=LABELS, like --benchmark-columns=min,max,mean. For more information on pytest-benchmark please visit the Usage Guide.

Parameter --benchmark-gpu-disable is to disable memory checks from Rapids GPU benchmark tool. Doing so speeds up benchmarking.

If you wish to skip benchmarks of SciPy functions add -m "not cpu"

Lastly, benchmarks will be executed on local files. Therefore to test recent changes made to source, rebuild cuSignal.

Example

pytest -k upfirdn2d -m "not cpu" --benchmark-enable --benchmark-gpu-disable --benchmark-columns=mean

Output

cusignal/test/test_filtering.py ..................                                                                                                                                                                                                                                   [100%]

[DOC] Install information for Jetson Nano

I think it might be possible to get this code running on the Jetson Nano, but I'm not able to at the moment.

The conda version for the Nano that I'm trying is Archiconda, https://github.com/Archiconda .

The Nano has Maxwell cores, which should be enough for this. But I don't think all the necessary dependencies have been put together in Archiconda, and I'm not exactly sure where to start. I get a series of PackagesNotFoundError messages saying that I can't install from current channels.

Before I go too much further, happy to provide more details as requested, or to understand whether this is intended to work or known not to work for some more fundamental reason!

There is a significant difference between registers usage with CuPy but not Numba.

These times are from Nsight Systems, using the attached python script. test.py.txt

Also, is it possible to overload Numba kernels? Supposedly it is with https://github.com/numba/numba/issues/431. But I'm unable to make it work.~~

I've added qdrep and sqlite files. It looks like CuPy compiles are getting cached in the same manner as Numba. cusignal.zip

As I continue to optimize, I'm noticing that even though the CuPy kernels may be 2x faster than Numba, the required launch time of the CuPy kernel take 2x longer than Numba. Making Numba the favorable option... Screenshot below. It's quite possible I'm doing something sub-optimal

[QST] Is lazy evaluation used ?

I'm trying to do a simple benchmarking of cuSignal vs signal on correlation. It seems that the correlate2d completes immediately, and the buffer transfer takes 2.8 seconds. Makes no sense for buffer size of 80 MBytes. Could it be the correlation is evaluated lazily only when buffer transfer is requested ?

%time signal_t_gpu = cp.asarray(signal_t)
%time pulse_t_2d_gpu = cp.asarray(pulse_t_2d)

%time corr_cusig = cusignal.correlate2d(signal_t_gpu, pulse_t_2d_gpu, mode='valid')

%time corr_cusig_np = corr_cusig.get()
%time corr_cusig_np2 = cp.asnumpy(corr_cusig)
%time corr_cusig_np3 = cp.asnumpy(corr_cusig)

and getting :

[BUG] channelize_poly() CUDA_ERROR_FILE_NOT_FOUND after Jetson conda install (0.16)

Describe the bug channelize_poly() function is not finding cusignal/filtering/_channelizer.fatbin on Jetson Nano.

Steps/Code to reproduce bug

import cusignal
cusignal.filtering.channelize_poly(cp.random.randn(128), cp.ones((16,))/16, 4)

Expected behavior channelize_poly returns channelized output.

Environment details (please complete the following information):

Environment location: [Jetson Nano SBC]
Method of cuSignal install: [conda] Following the Jetson install instructions to install a clone of branch-0.16:

git clone https://github.com/rapidsai/cusignal.git $CUSIGNAL_HOME

cd $CUSIGNAL_HOME
conda env create -f conda/environments/cusignal_jetson_base.yml

conda activate cusignal-dev

cd $CUSIGNAL_HOME/python
python setup.py install

Running cusignal inside a python script (cuspec.py in stack trace).

Additional context Ran test suite, and actually encountered similar errors (CUDA_ERROR_FILE_NOT_FOUND). I wasn't familiar with the test output so I wrote it off at the time. Do I need to build from source?

[BUG] [Jetson Nano Conda install hangs on installing pip dependencies]
Describe the bug When creating the conda environment on a Jetson Nano Development kit, the installation proceeds until installing pip dependencies, where it hangs indefinitely.

Steps/Code to reproduce bug Fresh Jetpack install on Jetson Nano board. Follow instructions for building from source on Jetson Nano exactly.

[PR-REVIEW] Load fatbin at runtime

This PR is to investigate the use of loading kernels via PTX and cubins. Instead of compiling them at runtime.

The idea is to skip the process from Source Code to PTX or cubin. This should eliminate the need to precompile desired kernels, making the UI a little more friendly.

There are pros and cons to both PTX and cubin.

PTX

Pro: We can choose a single architecture (default 3.0) and any hardware will JIT based on Compute Capability. Con: This can leave performance on the table and can be slower than cubins

Cubin

Pro: Optimal performance and (slightly) faster load because it skip the JIT Con: Requires a cubin for each supported architecture (i.e. sm30, sm35, sm50, sm52, sm60, sm62, sm70, sm72, sm75, sm80)

Each methode required more space for files and cu file (if we decide to load it)

Currently, using PTX method.

Anecdotal results. PTX and cubin is ~18x faster on first pass

[REVIEW] Use Numba 0.49+ API where required

https://github.com/numba/numba/pull/5197 refactors many of Numba's submodules. Mirror the required import changes in cusignal.

This keeps cusignal in sync with numba master and the 0.49 release candidate but breaks compatibility with the current numba release (0.48).

This should go in eventually but also needs to make sure we keep compatibility with whatever version of numba we're getting in the conda channels selected by our packaging (and certainly updates the minimum required version) - need help with this part.

[FEA] pytorch polyphase resampler

Opening this issue to facilitate discussion. A Pytorch compatible wrapper around cusignal's polyphase resampler is here (WIP).

@awthomp Where is a good place to put the source? Currently putting it in branch 22.08 in a new sub-directory python/cusignal/pytorch but curious if a place already exists.

Also the backward method works (passes gradcheck, uses cusignal correlate) but is not optimized. It can be re-implemented most likely as another resample_poly call (since it upscales and convolves). That is on the to-do list.

[BUG] FutureWarning from CuPy on `resample`

Describe the bug When resampling a CuPy array, we get a FutureWarning instructing us not to use a non-tuple sequence for multidimensional indexing:

/opt/conda/envs/rapids/lib/python3.9/site-packages/cusignal-22.4.0a0+g8878bf7-py3.9.egg/cusignal/filtering/resample.py:269: FutureWarning: Using a non-tuple sequence for multidimensional indexing is deprecated; use `arr[tuple(seq)]` instead of `arr[seq]`. In the future this will be interpreted as an array index, `arr[cupy.array(seq)]`, which will result either in an error or a different result.
  Y[sl] = X[sl]

Steps/Code to reproduce bug With latest 22.06 conda nightlies:

import cupy as cp
import cusignal

start = 0
stop = 10
num = int(1e8)
resample_num = int(1e5)

gx = cp.linspace(start, stop, num, endpoint=False)
gy = cp.cos(-gx**2/6.0)

gf = cusignal.resample(gy, resample_num)

Expected behavior Would not expect this warning to appear when resampling.

Environment details (please complete the following information):

Environment location: bare-metal
Method of cuSignal install: conda

Additional context Came across this issue while testing the filtering examples notebook.
