It enables users to fully leverage the computational ability of their computing resources for maximum performance for simultaneous seismic waveform processing, achieving real-time performance by identifying and utilizing the optimal computational configurations for their hardware. More information about the development, capabilities, and real-world applications about EQCCTPro can be read about in our research publication here.

Features

• Supports both CPU and GPU execution
• Configurable parallelism execution for optimized performance
• Includes tools for evaluating system performance for optimal usecase configurations
• Automatic selection of best-usecase configurations
• Efficient handling of large-scale seismic data

Installation Guide

There are two installation methods for EQCCTPro:

1. Method 1: Install EQCCTPro out of the box (for experienced users)
2. Method 2: Install EQCCTPro with sample waveform data (recommended for first-time users)

It is highly recommended that first-time users pull the EQCCTPro folder, which includes sample waveform data and code to help get acquainted with EQCCTPro.

---

Method 1: Install EQCCTPro (No Sample Data)

This method installs only the EQCCTPro package without the sample waveform data.

Step 1: Create a Clean Conda Environment for the Install

EQCCTPro requires Python 3.10.14 or higher as well as minimum Tensorflow packages. If you have a clean working environment, you can simply run pip install eqcctpro. However, if you have a nonclean environment, its highly recommended to create a new conda environment so that you can install the necessary packages safely with no issues. You can create a new conda environment with the correct Python version by using the following commands:

[skevofilaxc] conda create --name yourenvironemntname python=3.10.14 -y
[skevofilaxc] conda activate yourenvironemntname 
[skevofilaxc] python3 --version

Expected output:

Python 3.10.14

After activating your new conda environment, run the following command:

[skevofilaxc] pip install eqcctpro

You will have access to EQCCTPro and its functionality. However you will not have immediate access to the provided sample waveform data to use for testing. Youcan pull the waveform data either by downloading the .zip file from the repository or by following step 3.

Step 3 (Optional): Pull the EQCCTPro Folder

Although not required, it is highly recommended to pull the EQCCTPro folder to gain access to sample waveform data for testing.

[skevofilaxc] mkdir my_work_directory
[skevofilaxc] cd my_work_directory
[skevofilaxc] git clone --depth 1 --filter=tree:0 https://github.com/ut-beg-texnet/eqcct.git --sparse
[skevofilaxc] cd eqcct
[skevofilaxc] git sparse-checkout set eqcctpro

---

Method 2: Install EQCCTPro with Sample Data (Recommended for First-Time Users)

This method sets up EQCCTPro with a pre-created conda environment and sample waveform data.

Step 1: Clone the EQCCTPro Repository

[skevofilaxc] mkdir my_work_directory
[skevofilaxc] cd my_work_directory
[skevofilaxc] git clone --depth 1 --filter=tree:0 https://github.com/ut-beg-texnet/eqcct.git --sparse
[skevofilaxc] cd eqcct
[skevofilaxc] git sparse-checkout set eqcctpro

Step 2: Create and Activate the Conda Environment

A pre-configured conda environment is included in the repository to handle all dependencies.

[skevofilaxc] conda env create -f environment.yml
[skevofilaxc] conda activate eqcctpro

Step 3: Install EQCCTPro

After activating the environment, install the EQCCTPro package:

[skevofilaxc] pip install eqcctpro

This will install any remaining dependencies needed for EQCCTPro.

Using Sample Waveform Data

To understand how EQCCTPro works, it is highly recommended to use provided sample seismic waveform data as the data source when testing the package.

1-minute long sample seismic waveforms from 229 TexNet stations have been provided in the repository under the 230_stations_1_min_dt.zip file.

Step 1: Unzip the Sample Wavefrom Data

After downloading the .zip file through the GitHub methods above, run:

[skevofilaxc] unzip 230_stations_1_min_dt.zip

Step 2: Check and Understand the Directory Structure

The extracted data will contain a timechunk subdirectories, comprised of multiple station directories:

[skevofilaxc 230_stations_1_min_dt]$ ls
20241215T120000Z_20241215T120100Z
[skevofilaxc 230_stations_1_min_dt]$ cd 20241215T120000Z_20241215T120100Z

Each subdirectory contains mSEED files of different waveform components:

[skevofilaxc PB35]$ ls
TX.PB35.00.HH1__20241215T115800Z__20241215T120100Z.mseed  TX.PB35.00.HHZ__20241215T115800Z__20241215T120100Z.mseed
TX.PB35.00.HH2__20241215T115800Z__20241215T120100Z.mseed

EQCCT (i.e., the ML model) requires at least one pose per station for detection, but using multiple poses enhances P and S wave directionality.

You have successfully installed EQCCTPro and set up the required sample waveform dataset for testing.

Using EQCCTPro

There are three main capabilities of EQCCTPro:

1. Process mSEED data from singular or multiple seismic stations using either CPUs or GPUs
2. Evaluate your system to identify the optimal parallelization configurations needed to get the minimum runtime performance out of your system
3. Identify and return back the optimal parallelization configurations for both specific and general-use usecases for both CPU (a) and GPU applications (b)

These capabilities are achieved using the following core functions:

• EQCCTMSeedRunner (for processing mSEED data)

• EvaluateSystem (for system evaluation)

• OptimalCPUConfigurationFinder (for CPU configuration optimization)

• OptimalGPUConfigurationFinder (for GPU configuration optimization)

Processing mSEED data using EQCCTPro (EQCCTMSeedRunner)

To process mSEED from various seismic stations, use the EQCCTMSeedRunner class. EQCCTMSeedRunner enables users to process multiple mSEED from a given input directory, which consists of station directories formatted as follows:

[skevofilaxc 230_stations_1_min_dt]$ ls
20241215T120000Z_20241215T120100Z
[skevofilaxc 230_stations_1_min_dt]$ cd 20241215T120000Z_20241215T120100Z

Where each subdirectory is named after station code. If you wish to use create your own input directory with custom waveform mSEED files, please follow the above naming conventions. Otherwise, EQCCTPro will not work. Create subdirectories for each timechunk (sub-parent directories) and for each station (child directories). The station directories should be named as shown above. Each timechunk directory spans from the start of the analysis period minus the waveform overlap to the end of the analysis period, based on the defined timechunk duration.

For example:

[skevofilaxc 230_stations_2hr_1_hr_dt]$ ls
20241215T115800Z_20241215T130000Z  20241215T125800Z_20241215T140000Z

The timechunk time length is 1 hour long. At the same time, we use a waveform overlap of 2 minutes. Hence: 20241215T115800Z_20241215T130000Z spans from 11:58:00 to 13:00:00 UTC on Dec 15, 2024 and 20241215T125800Z_20241215T140000Z spans from 12:58:00 to 14:00:00 UTC on Dec 15, 2024

Each station subdirectory, such as PB35, are made up of mSEED files from seismometer different poses (EX. N, E, Z):

[skevofilaxc PB35]$ ls
TX.PB35.00.HH1__20241215T115800Z__20241215T120100Z.mseed  TX.PB35.00.HHZ__20241215T115800Z__20241215T120100Z.mseed
TX.PB35.00.HH2__20241215T115800Z__20241215T120100Z.mseed

EQCCT only needs one pose for the detection to occur, however more poses allow for better detection of the direction of the P and S waves.

After setting up or utilizing the provided sample waveform directory, and install eqcctpro, import EQCCTMseedRunner as show below:

from eqcctpro import EQCCTMSeedRunner

eval_cpu.evaluate()

EvaluateSystem will iterate through different combinations of CPU(s), Concurrent Timechunk and Station Tasks, as well as GPU(s), and the amount of VRAM (MB) each Concurrent Prediction can use. EvaluateSystem will take time, depending on the number of CPU/GPUs, the amount of VRAM available, and the total workload that needs to be tested. However, after doing the testing once for most if not all usecases, the trial data will be available and can be used to identify the optimal input parallelization configurations for EQCCTMSeedRunner to use to get the maximum amount of processing out of your system in the shortest amonut of time.

• cpu_id_list (list): default = [1]
  • List that defines which specific CPU cores that sched_setaffinity will allocate for executing the current EQCCTPro process and is the maximum amount of cores EvaluteSystem can use in its trial iterations
  • Allows for specific allocation and limitation of CPUs for a given EQCCTPro process
    • "I want this program to run only on these specific cores."
  • Must be at least 1 CPU if using GPUs (Ray needs CPUs to manage the Raylets (concurrent tasks), however the processing of the waveform is done on the GPU)
• min_cpu_amount (int): default = 1
  • Is the minimum amount of CPUs you want to start your trials with
  • By default, trials will start iterating with 1 CPU up to the maximum allocated

  • By default, if min_conc_predictions and conc_predictions_step_size are set to 1, a custom step size iteration will be applied to test the 50 sample waveforms. The sequence follows: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, n+5, 50].
• conc_station_tasks_step_size (int): default = 1
  • Is the concurrent station predictions step size you want each trial iteration to iterate with
  • By default, if min_conc_predictions and conc_predictions_step_size are set to 1, a custom step size iteration will be applied to test the 50 sample waveforms. The sequence follows: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, n+5, 50]
• start_time (str): default = None
  • The start time of the area of time that is being analyzed
  • EX. 2024-12-14 12:00:00
  • Must follow the following convention YYYY-MO-DA HR:MI:SC
  • Used to create a list of defined timechunks from the defined analysis timeframe
  • Must be the exact start time of the analysis time period (does not include the prior waveform overlap time IE. 2024-12-15 11:58:00 for a 2 minute waveform overlap time)
  • Also used in the EvaluateSystem() class to help users note the analysis timeframe in the results CSV file for future result review
• end_time (str): default = None
  • The end time of the area of time that is being analyzed
  • EX. 2024-12-15 12:00:00
  • Must follow the following convention YYYY-MO-DA HR:MI:SC
  • Used to create a list of defined timechunks from the defined analysis timeframe
  • Must be the exact end time of the analysis time period
  • Also used in the EvaluateSystem() class to help users note the analysis timeframe in the results CSV file for future result review
• conc_timechunk_tasks_step_size (int): default = 1
  • Is the concurrent timechunk predictions step size you want each trial iteration to iterate with
• timechunk_dt (int): default = None
  • The length each time chunk is (in minutes)
  • EX. timechunk_dt = 10 and the analysis period is 30 minutes, then three 10-minute long timechunks will be created
• waveform_overlap (int): default = None
  • The duration (in minutes) for which each waveform oself.start_timeverlaps with the others
• tmp_dir (str): default = 1
  • A temporary directory to store all temp files produced by EQCCTPro
  • Used to help ease system cleanup and to not write to system's default temporary directory
• set_vram_mb (float)
  • Value of the maximum amount of VRAM EQCCTPro can use
  • Must be a real value that is based on your hardware's physical memory space, if it exceeds the space the code will break due to OutOfMemoryError
• selected_gpus (list): default = None
  • List of GPU IDs on your computer you want to use if mode = 'gpu'
  • Non-existing GPU IDs will cause the code to exit

Finding Optimal CPU/GPU Configurations

After running EvalutateSystem, you can use either the OptimalCPUConfigurationFinder or the OptimalGPUConfigurationFinder determine the best CPU or GPU configurations (respectively) for your specific usecase:

from eqcctpro import OptimalCPUConfigurationFinder, OptimalGPUConfigurationFinder

csv_filepath = '/path/to/csv'

cpu_finder = OptimalCPUConfigurationFinder(csv_filepath)
best_cpu_config = cpu_finder.find_best_overall_usecase()
print(best_cpu_config)

optimal_cpu_config = cpu_finder.find_optimal_for(cpu=3, station_count=2)
print(optimal_cpu_config)

gpu_finder = OptimalGPUConfigurationFinder(csv_filepath)
best_gpu_config = gpu_finder.find_best_overall_usecase()
print(best_gpu_config)

optimal_gpu_config = gpu_finder.find_optimal_for(num_cpus=1, gpu_list=[0], station_count=1)
print(optimal_gpu_config)

Both OptimalCPUConfigurationFinder and OptimalGPUConfigurationFinder each have two usecases:

1. find_best_overall_usecase

• Returns the best overall usecase configuration
  • Uses middle 50% of CPUs for moderate, balanced CPU usage, with the maximum amount of stations processed with the minimum runtime

2. find_optimal_for

• Return the paralleliztion configurations (EX. concurrent predictions, intra/inter thread counts, vram, etc.) for a given number of CPU(s)/GPU(s) and stations
  • Enables users to quickly identify which input parameters should be used for the given amount of resources and workload they have for the minimum runtime possible on their computer

A input CSV directory path must be passed for the classes to use as a reference point:

• csv_filepath (str)
  • Directory path where the CSV's outputted by EvaluateSystem are

Using OptimalCPUConfigurationFinder.find_best_overall_usecase(), no input parameters are needed. It will return back the best usecase parameters.

For OptimalCPUConfigurationFinder.find_optimal_for(), the function requires two input parameters:

• cpu (int)
  • The number of CPU(s) you want to use in your application
• station_count (int)
  • The number of station(s) you want to use in your application

OptimalCPUConfigurationFinder.find_optimal_for() will return back a trial data point containing the mimimum runtime based on your input paramters

Similar to OptimalCPUConfigurationFinder.find_best_overall_usecase(), OptimalGPUConfigurationFinder.find_best_overall_usecase() will return back the best usecase parameters and no input parameters are needed.

For OptimalGPUConfigurationFinder.find_optimal_for(), the function requires three input parameters:

• cpu (int)
  • The number of CPU(s) you want to use in your application
• gpu_list (list)
  • The specific GPU ID(s) you want to use in your application
  • Useful if you have multiple GPUs available and want to use/dedicate a specific one to using EQCCTPro
• station_count (int)
  • The number of station(s) you want to use in your application
