Credits pricing

Standard Credits
Standard Credits are valid for one year
Great for ad hoc simulations at irregular intervals

Standard credits

Standard credits can be used for any application. Credits deductions are calculated based on per core, per hour and type of applicaton used.

Amount Price Total
100 credits .25c $25
2500 credits .20c $500
5000 credits .15c $750
High Volume Rates
Great for running many simulations over a short period of time. Reserve your cores from 7 to 30 days
The clock starts ticking only when you run your first simulation.

Standard high volume rates

There are different high volume rates and some of them are application specific. If an application is not mentioned in its own high volume rate table, the standard high volume rate applies.

8 cores 16 cores 32 cores 64 cores
7 days $268,80$537,60$1 075,20$2 150,40
14 days $470,40$940,80$1 881,60$3 763,20
30 days $864,00$1 728,00$3 456,00$6 912,00

High volume rates for ADF

8 cores 16 cores 32 cores 64 cores

30 days $1 728,00$3 456,00$6 912,00$13 824,00
Academic Credits
Academic Credits are valid for 60 days
Great for academic use
Credits can be shared within a research group

Academic Credits

These rates are only available to users registered with an educational email address. The pricing for academics are as follows:

Amount Price
1 Credit $0.11

A minimum of 100 credits need to be bought.

In order to buy credits or load a voucher, please log in.

How the standard and academic credits work

On payment credits used are calculated in the following way : Per hour x CPU x per variable rate.

The variable rate depends on the application. All applications except for ADF is a variable rate of 1. ADF is a variable rate of 2.

When referring to a CPU we are talking about individal cores on a processor. So a quad core processor would have 4 cores. Hyperthreading is disabled.

An example of how the credits are calculated is listed below.

Appliction CPU Hours Variable Rate Total credits deducted
ADF 12 x 2 x 2 = 48
All others 12 x 2 x 1 = 24

FEKO suite version 7.0 available on CrunchYard

Feko, the comprehensive electromagnetic simulation software, has released their 7th version, and it’s available on CrunchYard. The new version adds a finite difference time domain solver (FDTD) as well as a powerful hybridization of Multilevel Fast Multipole Method and Physical Optics (MLFMM and PO). The release has been eagerly awaited and features three new import file formats (Gerber, ODB++ and 3Di). FEKO 7 is also available via FTP and scripting access on CrunchYard for advanced users.

CrunchYard is pleased to announce direct scripting and FTP access for advanced users.

This new service allows advanced users to interact dynamically with CrunchYard in conjunction with our easy to use web portal. Parameter variations across simulations can be scripted in your own code and submitted to CrunchYard in real time.

In additional, all FTP and scripting activity is mirrored on users personal CrunchYard profile.

FTP and scripting access is free and granted on a request basis. The new service applies to all codes on CrunchYard.

Other licensed codes are available on request.
