This article explores some of the hardware considerations when configuring a system for use with arivis Pro/Vision4D.
Summary
Computers intended for use with arivis Pro / Vision4D should have:
- More CPU cores rather than higher clock speeds
- Lots of fast local storage (preferably with a disk or disk partition dedicated entirely to temporary documents)
- A dedicated GPU is necessary for 3D rendering
- An NVIDIA GPU with 8GB of VRAM is required for Deep Learning applications
- 64 GB of RAM is more than enough for most applications, more is better but favour SSD storage over RAM if working on a budget
Introduction
arivis Pro / Vision4D has been built from the ground up for the visualization and processing of very large datasets while being RAM independent. This, consequently, has a significant effect on how the software is implemented and affects how we deal with the most common bottlenecks in computing.
CPUs
Because CPUs are generally limited by their clock speeds, a common workaround for this limitation is to use parallelization. Not all processes can be parallelized, but what can be parallelized generally has been in arivis Pro / Vision4D. Therefore, a computer with more cores is generally preferable to a computer with a higher clock rate. Buying computers with 2 or more multi-core CPUs can be a more cost-effective way to increase your core count than buying a single CPU with more cores. However, CPU speed and core count may also be limited by memory usage.
We recommend a minimum of 4 CPU cores (though Vision4D will work with fewer if that is what is available), but 8 or more cores are preferable for most image analysis operations.
Memory
Generally speaking, everything that needs to go through the CPU must first be transferred to the RAM. Furthermore, the results of any CPU processing will also typically be stored in RAM, at least temporarily. This means that you generally need twice as much RAM as the data you are trying to process.
arivis Pro / Vision4D has been designed to work around this limitation by using blocking, and temporary documents.
Blocking involves just-in-time loading of portions of the dataset within the available RAM so that it is never necessary to hold the whole dataset in RAM. This means that arivis Pro / Vision4D can process multi-terabyte-sized datasets on a computer with as little as 16GB of RAM or even less.
Having stated this, arivis Pro / Vision4D will use whatever memory is available, and having more RAM may speed up some RAM-intensive processes (e.g. segmentation and processing of very large complex objects).
The other implication is that if we are not holding the whole data in RAM, we need to create temporary documents on the hard disk to store the result of image processing operations which affects how much storage we will need.
Because of this architecture, arivis Pro / Vision4D will allow you to process datasets larger than 500 GB with as little as 4 GB of RAM, but we recommend a minimum of 8 GB while 16 GB is preferable. As RAM gets a lot more expensive the more you add and Vision4D is not dependent on RAM availability to such an extent, we do not typically recommend that you buy more than 128 GB of RAM, except for systems intended for multi-user concurrent usage. We generally recommend 8 GB of RAM per CPU computing core.
Storage
Local storage is key to arivis Pro / Vision4D's performance. Through extensive use of Just-in-Time loading and temporary documents, arivis Pro / Vision4D relies heavily on local storage. In many ways, more so than it relies on RAM. Therefore, it is important to have plenty of local storage, both to store documents locally while working with them to enable fast just-in-time loading, and to allow for the creation of temporary documents to store the results of any image processing operations.
Using fast solid-state drives (SSDs) can provide marginal gain improvements for many read/write-intensive applications, but generally getting more storage is preferable to buying faster storage. We generally recommend having at least 5x as much free disk space as the documents you are trying to process. Note that both the active and temporary documents can use compression to further increase the size of files that can be processed locally.
Buying RAID storage where multiple relatively slow spinning disk drives run in parallel to increase speed and reliability can be a more cost-effective way to add a lot of fast storage.
Network-based or removable storage is generally not recommended due to the possibility that the connection may be intermittent, and the overheads in data transfer under such conditions can lead to significant slow-downs in performance.
Graphics Cards
Graphics cards are essential to 3D and 4D visualization, highly recommend or for Machine Learning, and necessary for Deep Learning. Because of the high demands that arivis Pro / Vision4D places on such hardware for 3D rendering and ML/DL there are a few things to bear in mind.
First, purely for 3D rendering arivis requires GPUs that support OpenGL 4.6 and above. Most GPUs released after 2017 should meet this requirement, with some exception for integrated graphics.
Typically, integrated graphics are generally not recommended. Computers without a dedicated GPU commonly use these integrated graphics as a low-cost and low-power consumption alternative to dedicated cards but make several sacrifices in the process that can prevent the 4D Viewer from working optimally, or even at all in some cases. Aside from integrated graphics, there are not many GPUs that we do not recommend for 3D visualisation.
Secondly, the other thing that arivis uses GPUs for is to accelerate Machine Learning and Deep Learning tasks. This acceleraration uses NVIDIA CUDA libraries and so only NVIDIA GPUs are supported for ML and DL. Also, a minimum of 8GB of video memory (VRAM) is required.
Finally, when it comes to recommendations for specific GPUs, since this is a highly dynamic environment with multiple specs available, we do not recommend any specific specification or manufacturers, but the following points may make your decision easier.
First, as mentioned above, we require NVDIA GPUs with at least 8GB of VRAM as a minimum requirement for DL and this is a good starting point for choosing a GPU. even if you do not intend to use ML and DL in the immediate future, having these specifications will minimize the chances that a hardware change will be required if the analysis requirements change.
Second, gaming GPUs generally provide a much better price/performance balance (EUR 800 for a high-end gaming GPU Vs EUR 4500 for an equivalent Professional card). In most cases the price difference will not be reflected in a noticeable improvement in performance for either visualisation of ML Tasks. But "Pro" cards do offer some features that can be useful depending on your usage.
For example, gaming cards often do not provide good levels of support for use with Remote Desktop Protocols or Virtual Machines. Some specialized drivers may be available for some cards, but generally using 3D rendering over RDP is not recommended. However, since having access to a machine with enough local storage for processing very large data may only be possible with server-style machines that aren't typically well suited to an office environment, using RDP or VMs in such cases is a preferable compromise. If that is your case, we recommend Pro Server cards because they provide better support for shared usage.
Also, Pro cards often add features that we cannot make use of that are intended specifically for industrial CAD applications. This adds a lot of cost for few benefits that arivis Vision4D can actually leverage. However, Pro cards can also typically be configured with a lot more video memory, and while we typically won't use this additional memory for pure 3D visualization and navigation since it would most likely be beyond the capabilities of the GPU to handle such amounts of data smoothly for these applications, the extra memory can be useful to speed up the rendering of high-resolution snapshots and animations of large datasets, and for ML/DL tasks.
For basic usage, a mid-range gaming GPU will prove more than adequate. However, for highly demanding applications like VR we recommend a minimum of RTX 2080 Ti or better.
Operating System
arivis Pro / Vision4D is a program for Windows 64-bit operating systems. There is no MacOS or Linux version. Please have a look at this article for more information on running Vision4D on Apple hardware. The minimum requirement for support is Windows 10, but Windows 11 is also supported. The software may work partially on earlier versions, but note that these are not supported configurations.
Also, while the low memory requirements of Vision4D make it theoretically capable of processing large datasets in 32-bit environments, the high cost of maintenance of two separate builds of the software and the relative scarcity of 32-bit systems means we no longer offer a 32-bit version.
Conclusions
So, which hardware configuration should you choose?
The computer you already have, as long as it runs Windows 10 or better, has 100GB or more of free hard disk space, and has a dedicated GPU that supports OpenGL 4.3 will probably be fine for most image analysis tasks and visualization. But if you want to buy a new machine dedicated to arivis Pro / Vision4D then the following recommendations are useful guidelines.
