PinnedGigE Vision SDK || libfsock /w GVAThere is a shift in the industry for using cameras providing data via a Gigabit Ethernet Interface. Given the increase in resolution of 4K and beyond, 10Gbit but also 25Gbit Ethernet is becoming popular. One reason being that the network infrastructure is becoming very attractive from a price point of…Exanic3 min readExanic3 min read
Pinnedlibfsock: A versatile API with a focus on ultra low latency and efficient data handlingTechnologies pathing the way for low latency When a trend to using COTS (Commercials off the shelf) became popular for HPC (High Performance Computing), a raze to zero — or best in class latency started so that parallel applications can scale out to the maximum. For decades special purpose machines…Low Latency9 min readLow Latency9 min read

May 19, 2022Kernel Bypass performance. Is it OS agnostic ?Today there is a tendency to use Linux as a platform for HPC or HFT. It was quite the opposite a few years back. It’s a result of at least two things: lack of innovation but also lack of attitude. Looking back there was a short window in which Microsoft…Windows Kernel Bypass3 min readWindows Kernel Bypass3 min read
Dec 27, 2021Introducing LIBFSOCK-PROXYWith the introduction of a proxy to our popular LIBFSOCK middleware library, we add support for multiple vendor NICS/devices per application. The architectural design has the concept of a proxy which will allow for registration of different providers (which are vendor specific). The traditional approach was that the API would…Low Latency2 min readLow Latency2 min read
Nov 8, 2021I/O connectivity, a new (5th) generation is showing offFor a long time CPUs were limited because of bottlenecks in I/O. Those bottlenecks were tackled in various places and gradually improved. We first saw CPU caches taking care of delays in memory access. Caches with varies levels (L1, …, L3) were introduced but also main memory got a lot…400gbe5 min read400gbe5 min read

For some use cases like 4K streaming (video) this is already a requirement. In finance (trading), we see network upgrades on the south end of things. While we can easily see that it more than doubles the potential…Exanic Windows4 min readExanic Windows4 min read
Aug 22, 2021Support for 25GbE is available on ExaNIC X25Happy to share the news of true support for 25GbE environments. With a recent firmware release, true 25GbE support is coming to the ExaNIC family. This enables the NIC to choose to run either 10GbE or 25GbE modes. How does this affect bandwidth? With PCIe Gen3 we have about 60Gbits…Exanic Windows1 min readExanic Windows1 min read
