<description>Fast Things First Hybrid Meetup #42 took place 2024-04-30 at CHECK24 Leipzig Office at Altes Landratsamt. We had two talks that revolved around Go and performance: Patrick Vahl gave a great overview about SIMD in Go and what is possible (and not possible), today. Examples from the talk can be found here: Crash129/go-simd-example. A few points from the talk:
17+
performance gains can be significant try to isolate SIMD as much as possible The difficulty with a general purpose approach to SIMD [&amp;hellip;] is that the performance can be dramatically different on different processors.</description>

48+
<a href="https://check24.de">CHECK24</a> Leipzig Office at Altes Landratsamt. We had two
49+
talks that revolved around Go and performance: <a href="https://github.com/Crash129">Patrick Vahl</a> gave a great
50+
overview about SIMD in Go and what is possible (and not possible), today. Examples from the talk
51+
can be found here:
52+
<a href="https://github.com/Crash129/go-simd-example">Crash129/go-simd-example</a>. A few points from the talk:</p>
53+
<ul>
54+
<li>performance gains can be significant</li>
55+
<li>try to isolate SIMD as much as possible</li>
56+
</ul>
57+
<blockquote>
58+
<p>The difficulty with a general purpose approach to SIMD [&hellip;] is that the performance can be dramatically different on
59+
different processors. &ndash; <a href="https://github.com/golang/go/issues/53171#issuecomment-1142953120">go/issues/53171#issuecomment-1142953120</a></p>
60+
</blockquote>
61+
<ul>
62+
<li>Go uses its own assembly syntax as an intermediate representation, more on that in <a href="https://go.dev/talks/2016/asm.slide#1">The Design of the Go Assembler</a> (2016)</li>
63+
<li>there are various approaches to SIMD and Go including <a href="https://github.com/mmcloughlin/avo">avo</a>, <a href="https://github.com/kelindar/gocc">gocc</a>, and more - see: <a href="https://github.com/Crash129/go-simd-example?tab=readme-ov-file#examples-of-methods-to-use-simd-in-go">Examples of methods to use SIMD in Go</a></li>
64+
<li>explore the assembly generated for Go programs via <a href="https://godbolt.org/z/oKvWhxqqn">compiler explorer</a></li>
65+
</ul>
66+
<p>While SIMD support is still a topic of discussion, e.g. in <a href="https://github.com/golang/go/issues/53171">#53171</a>, there exist usable approaches today.</p>

69+
<p>Thanks a lot to <a href="https://check24.de">CHECK24</a> for hosting the event in their
70+
nice office (with a view). Looking forward to our next event together which is
71+
planned for October 2024.</p>

<ul>
74+
<li>A good use case for <a href="https://man7.org/linux/man-pages/man2/mmap.2.html">mmap</a> is a parallel processing of read only data (that can be bigger than the physical RAM);
75+
there is an experimental package in the
76+
<a href="https://pkg.go.dev/golang.org/x/exp/mmap">x/exp/mmap</a> and a library <a href="https://github.com/edsrzf/mmap-go">edsrzf/mmap-go</a>. The concept of virtual
77+
memory goes back to one of the first super computer
78+
<a href="https://en.wikipedia.org/wiki/Atlas_(computer)">Atlas</a>.</li>
79+
<li>The <a href="https://github.com/simdjson/simdjson">simdjson</a> project explores the use of SIMD for record breaking, high performance JSON processing</li>
