ask about compiling on arm. #12
Comments
You can contact me in Slack or here when you face a problem and I will try to help you resolve it!
The idea is to use more CPU registers simultaneously. By using Neon (for aarch64) and AVX (for 86_64) you can process more data with a single CPU instruction. For example if you have an array of integers and you want to get the sum of them then normally you would use an accumulator (arr[0]) and add to it arr[1], then to the result add arr[2], and so on. Each addition operation would be one CPU cycle. By using SIMD (single instruction - multiple data) you can use several CPU registers for one CPU cycle. For example the accumulator will be the sum of arr[0]+arr[1]+arr[2]+arr[3], then the result will be increased with arr[4]+arr[5]+arr[6]+arr[7], etc.

Hi, Thank you very much. Here are some questions I'll sort out. |

The error information is too few to I can see the cause. Would you mind to point out this problem? This is the error report when I use |
No. These files were custom implementation by the PR author.
Here is a PR that uses sse2neon - lbcb-sci/graphmap2#23
If you know how to make the improvements then it is better to send a Pull Request! |

@yangxingyu588 Let's use Disccussions instead. It supports threading and it will be easier to follow the questions and their answers. |
Thank you, but l can't open this page:https://github.com/bio-arm/bio-arm.github.io/discussions |
What should l do to resolve it. |

@yangxingyu588 About AC-DIAMOND: Maihj/AC-DIAMOND#8 |
Hi@martin, I use bioconda-utils build --packages ac-diamond to build ac-diamond However, the build still fails and there are few error messages, could you please help me solve the problem? |
|
We will need a need release/tag of AC-DIAMOND to be able to compile it on ARM64. |

Cool, l'm going to try it. l have a question to ask. Some Source code is not compiled on Use |
|
One problem that I can see is with reproducibility. If you lose your local modifications it might be hard to re-build the package again if needed. |

Thank you very much, ac-diamond has built successfully.
yes, you're right, but there are many aarch64 versions that I have simply adapted to that have not been uploaded to the community.
Yes, this is certain. Your adaptation is very cool, it is just an example to illustrate that I used a local file in the |
hi @martin-g @Yikun .What l do now is to use bioconda-utils to build bioconda community software, such as bwa, ac-diamond, etc. l have no foundation, and l often encounter some
makefileandcmakeproblems. l would like to ask what can be referred to in this respect to get started quickly. Thank you very much for your advice.ln addition
