AXIS Recommended Equipment
A Quick Guide to Hardware and Operating Systems
(Revised Dec 7th 2011)
What's changed recently?
Intel has introduced a new type of i5/i7 chip based on the Sandy Bridge design. At identical clock speeds, these run about 15% faster than earlier i5/i7 designs. They are available as desktop and notebook processors, all with 4 digits in the model number (e.g. i7-2600). There are no AMD processors which we can recommend at this time.
Advice
Please call Phil Gold (416-250-2596) for up to the minute information or advice, since the situation changes quickly.
Processors
AXIS makes strong demands on the floating-point capabilities of your processor, so we will always advise you to buy the best floating-point performance you can afford.
1. Notebooks
Intel Quad-Core Chips
We recommend these Core i7 chips (Sandy Bridge) for the highest possible performance in a laptop today when using distributed processing. Sandy bridge shows a significant boost in performance at any given clock speed over earlier i7 designs.
- Core i7-2960XM 2.70 GHz
- Core i7-2920XM 2.50 GHz
- Core i7-2860QM 2.50 GHz
- Core i7-2760QM 2.40 GHz
- Core i7-2820QM 2.30 GHz
- Core i7-2720QM 2.20 GHz
- Core i7-2670QM 2.20 GHz
- Core i7-2675QM 2.20 GHz
Intel Dual-Core Chips
The following dual core Sandy Bridge models are also recommended for a lower budget:
- Core i7-2640M 2.80 GHz
- Core i7-2620M 2.70 GHz
- Core i5-2540M 2.60 GHz
They have high clock speeds but fewer cores.
2. Desktops
Intel Six-Core Chips
The following chips (Sandy Bridge-E) carry our top desktop recommendation.
- Core i7-3960X 3.30 GHz
- Core i7-3930 3.20 GHz
Intel Quad-Core Chips
Intel's Sandy Bridge quad core chips carry a recommendation if you cannot afford a six core processor.
- Core i7-2700 3.50 GHz
- Core i7-2600 3.40 GHz
- Core i5-2500 3.30 GHz
3. Workstations and Servers
Racks of dual-processor servers are a popular choice for scaling AXIS under Distributed Processing and Grid Computing. Where space is at a premium, Blade servers do an excellent job. Please note that disk drives capacity and speed are critical in these applications – please call for details.
Intel Xeon
For dual-processor servers, we recommend the current generation 5600 series Xeon six-core processors based on i7 technology. These servers hold 12 cores.
- Xeon X5690 3.46 GHz 6 Cores (The best Xeon processor currently available)
- Xeon X5680 3.33 GHz 6 Cores
- Xeon X5675 3.06 GHz 6 Cores
- Xeon X5670 2.93 GHz 6 Cores
Note: Due to the extreme workload placed on the drive systems in multi-processor servers and the availability of higher clock rates in smaller servers, we strongly recommend 2 processor servers over 4 processor or 8 processor servers.
The best 4 processor server (40-cores) will be based on the following chip (Westmere EX) but we cannot recommend it:
- Xeon E7-4870 2.40 GHz 10 Cores

These tests can be quite sensitive to the types of jobs run in AXIS, and to the disk drives and memory systems in the PC. For multiple processors and cores, distributed processing is turned on using the automatic helper option.
I also want to draw your attention to some factors that can stand between you and good performance:
- Hyper-Threading . We strongly recommend that you turn off Intel Hyper-Threading when running on Intel processors. It will adversely affect AXIS run time.
- Real time virus checking . This can cause a massive slowdown in AXIS run times – up to four times slower. It can also make AXIS unstable, leading to random crashes, since it can lock files AXIS needs to open. We require you to add the directories that AXIS writes to into your exclusion list if you run real time scanning. These directories include the directory where AXIS is installed, the SPARE directory, the Dataset Path and the location of the Import / Export database. For details: www.ggy.com/support/kbase/kbdetails.asp?searchterm=&articleid=271
- Formula Tables Accelerator . To get the best performance if you are using Formula Tables, remember to turn on the Formula Tables Accelerator.
- Network bandwidth and latency . We recommend a fast network. We require at least 1Gbps for distributed processing or GridLink. To check whether your network is providing good performance, you can run this simple test. Run an AXIS Calendar Year Recalculation batch job, without distributed processing, on identical datasets residing in two locations – first in the same machine where AXIS is running, and then in a location across the network. If the two times vary by more than 5%, then you have a problem. Please contact GGY for details.
AXIS needs at least 1GB per processor core. If you are buying a new machine it is better to buy at least 2 GB per processor core.
If you are running GridLink or the StochasticTools module, you will need extra memory. We require at least 2 GB of memory per processor core and recommend 4GB per core.
Please note that even if you have enough memory we strongly advise you to not run any disk or processor intensive applications while performing AXIS runs. AXIS itself is going to use the maximum amount of CPU power and disk access bandwidth available - especially when distributed processing is used. As a result, other applications running concurrent processes may affect performance and cause AXIS to become unstable.
AXIS allows you to export assumptions and projections. This can take up a lot of disk space. We suggest a minimum of 250 GB for a laptop and 500 GB for a desktop computer, not because AXIS needs this much space, but because these disks are extremely inexpensive today. The AXIS System files take up about 400 MB.
AXIS requires a screen resolution of 1024 by 768 (XGA) and preferably much higher.
For a laptop we recommend at least a 14-inch screen and for a desktop at least a 19-inch LCD screen – the bigger the better.
We distribute AXIS and all updates via the Internet. If you do not have a good Internet connection we can supply AXIS on a CD. This CD can be read in any optical drive.
GPGPU (General-purpose computing on graphics processing units)
Our System Design team continues to research, monitor and test emerging technology in the GPGPU space that may be used to accelerate certain AXIS calculations. Currently the serious limitations of this technology in terms of memory, programming language and compiler support are such that it is not practical in AXIS today. The GPGPU technology is evolving rapidly, as is the language and compiler support, so we are optimistic that there will be a point at which we can provide support for GPGPU technology in an effective way. We will continue our research efforts in this area.
Operating Systems
We currently support and recommend Windows XP, Windows 2003 Server, Windows 2008 Server, Windows HPC Server (including R2) and Windows 7. We have found them to be very stable and much easier to manage than previous versions of Windows.
We require Microsoft .NET Framework 3.5 SP1. Version 3.5 SP1 can coexist with earlier versions of the .NET Framework which should not be removed since they may be required for earlier versions of AXIS.
Please note that this component is free of charge and is available for download from Microsoft web site.
Note that Microsoft Windows Operating Systems are available in 32 bit and 64 bit versions. We recommend the 64 bit versions because they allow the use of large amounts of memory, while Windows 7 32 bit, Vista 32 bit and XP 32 bit are limited to 3GB and Windows Server 32 bit Standard Edition and Windows Server 2008 32 bit Standard Edition are limited to 4GB.
For all GridLink farms we now recommend Microsoft HPC Server 2008 R2 operating system . This 64 bit O/S is a subset of Windows Server 2008 64-bit edition R2 and offers top performance and very inexpensive licensing.

Recommended Hardware for a GridLink Farm
You may be considering a 12 core farm or a 2048 core farm, or something in between. We strongly recommend you to consider your future needs before setting up even a small farm, so that you can continue to use the hardware you choose now as part of the larger farm you may need tomorrow.
