How does it work?
Microbiome analysis can be sped up in several ways using GPUs. They can be helpful, for example:
Process large datasets
Microbiome data is frequently pervasive and diverse. It can be analyzed with challenging conventional CPUs. Specialized processors, known as GPUs, are helpful for parallel computation.
It implies that they can do several calculations simultaneously. It qualifies them for jobs like microbiome analysis, which may require data processing.
One microbiome sample, for instance, may contain millions of DNA sequences. Researchers need to employ several computer techniques to analyze these sequences.
On conventional CPUs, these techniques can be computationally expensive and time-consuming. However, GPU technology can accelerate these techniques by orders of magnitude.
GPUs can perform multiple calculations at the same time. For example, a single GPU can process thousands of DNA sequences simultaneously.
It can be helpful to analyze large datasets of microbiome data much faster than traditional CPUs.
In addition to speeding up the analysis process, GPUs can also improve the accuracy of microbiome analysis.

Some of the ways that GPUs can be used to visualize microbiome data include:
Heatmaps
A heatmap is a visualization that shows the number of microbes in a microbiome sample. Each cell in the two-dimensional matrix reflects the quantity of a specific type of microbe in a particular area.
Each cell's color indicates the number of microorganisms. Therefore, deeper hues denote more numbers, and lighter shades represent fewer numbers.
GPUs generate heatmaps of microbiome data by performing the following steps:
- The microbiome data is divided into a grid of cells.
- The abundance of each microorganism in each cell is calculated.
- The color of each cell is assigned based on the quantity of the microorganism in that cell.
A GPU can divide the microbiome data into a grid of cells in the first stage. Therefore, GPUs' ability to perform parallel computing enables them to split the work of organizing data into a grid of cells into numerous more minor tasks. Then, carry out each task simultaneously.
This can substantially speed up the data partitioning into a grid of cells.
A GPU is beneficial for the second stage, which involves figuring out how many microorganisms are present in each cell. All of this is because of how adept GPUs handle mathematical operations.
Therefore, they can substantially speed up the procedure of estimating the amount of each microorganism in each cell because they can carry out these computations much more quickly than CPUs.
A GPU can also be helpful for the third stage, which determines the color of each cell based on how many microorganisms are present in that particular cell. GPUs can perform parallel computing.
Therefore enabling them to assign the colors to the cells concurrently. It substantially hastens the process of giving the cells their respective colors.

The distinct microbial communities that are present in the soil sample might be identified using this heatmap.
Additionally, it might be used to monitor alterations in the microbial community over time or in response to various environmental factors.
Tree
We can visually observe the relationships between the microorganisms in a microbiome sample using trees.
Therefore, they are often helpful in distinguishing between the various microbial communities present in a sample.
Moreover, they are also helpful in monitoring changes in the microbial community over time or in response to different environmental circumstances.
Microbiome data trees can be created on GPUs significantly more quickly than on CPUs.
This is because GPUs can perform parallel computing, which allows them to split the process of creating the tree into numerous more minor tasks and then carry out each task simultaneously.
It can result in a significant speedup in the tree generation process.
Various methods can produce the generation of microbiome data trees on GPUs. Utilizing a hierarchical clustering technique is one typical strategy.
Similar microorganisms are grouped by hierarchical clustering methods to function. GPUs can expedite the hierarchical clustering process by doing the clustering algorithms in parallel.
Employing a phylogenetic tree algorithm is another typical method for creating trees from microbiome data.
Therefore, reconstructing the evolutionary links of microorganisms is how phylogenetic tree algorithms function.
GPUs can accelerate the phylogenetic tree reconstruction procedure by running the tree reconstruction calculations in parallel.
GPUs can also be helpful to display microbiome data as trees. Researchers who desire to delve deeper into the interactions between microorganisms may find this useful.
Moreover, Researchers can study the data in real-time using interactive visualizations of microbiome data trees produced by GPUs.
A group of researchers at the University of California, San Diego, used GPUs to generate trees of microbiome data from the human gut. The researchers found that GPUs could generate trees of microbiome data much faster than CPUs.
This enables them to study the relationships between microorganisms in the human gut in more detail.
Networks
Networks are helpful in visualization to show how different microorganisms interact in a microbiome sample.
Therefore, they are frequently employed to distinguish between the microbial communities in a sample and monitor microbial community changes over time or in response to various environmental factors.
GPUs can be helpful in various ways to create networks using microbiome data. A correlation network algorithm is one such method.
Correlation network methods are used to find pairs of microorganisms that are highly associated with one another.
Therefore, GPUs can hasten the development of correlation networks by doing the correlation calculations in parallel.
Applying a metabolic network algorithm is another typical method for creating networks of microbiome data.
Algorithms for metabolic networks detect pairs of microorganisms that collaborate on a metabolic pathway.
However, by running the route analysis calculations in parallel, GPUs can hasten the creation of metabolic networks.
