Oct 2015 – EMIGMA V9.0 release

We are pleased to announce the release of a dramatically new version of EMIGMA. There are 2 radical changes to this new version: first and most importantly, the upgrades to computation speeds and accuracy and secondly, and important to large institutions, is the ability to use a network dongle to ensure both security and better access for users not using the software on a constant basis.

New Fortran Compiler
For many of our processing intensive algorithms, we utilize Fortran as this is still the fastest and most accurate language for massive computations. Intel having purchased copyright to the DEC Fortran compiler from Compaq (HP), began development of an improved compiler optimized for its chips eventually releasing a version in 2008 which provided capabilities to use multiple core processors as well as providing array processing capabilities. During the early years of the millennium, there were still many CPU’s being used but in the last 5 years, Intel has now dominated the market. AMD is another significant provider but its chips utilize the Intel architecture and thus the new compiler is compatible.

In the past year, we have been experimenting with the use of this new compiler and have been very pleased and surprised by the results. First, simply modifying the code to be compatible with the new compiler and re-compiling, we discovered huge unexpected improvements. First, and probably most important, massive computing on an Intel chip is now as stable as it has been historically on the AMD chips. Secondly, the floating point operations are more accurate than our older Microsoft FORTRAN compiler and then the most pleasing improvement, a general 5 times reduction in computation time! And this improvement is without the use of multi-core processing of any kind. The other aspect is the ability to implement use of the multi-core processors now available on virtually any computer. This capability now turns some tasks from being a day-long computation to only minutes.

Specific V9.0 Release Implementations
It will take some time to translate all of our algorithms into code that can be compiled with this new compiler but this will be an ongoing aspect of V9.0. However, for the release, we have implemented modifications to four applications. First, the 3D gravity inversion has been implemented for the new compiler but with only matrix operations using array processing capabilities. But, this has dramatically improved the speed and thus now allows very large data sets and very large inversion grids, producing inversions in reasonably short times. The 3D magnetics inversion, has been completely redeveloped to utilize the new compiler for array processing and multi-processor computations. The beauty of this new compiler, is that it will utilize an optimum amount of the system resources without threatening the stability of the operating system as with other multiprocessing compilers which also allows the user to intervene and do other tasks. Intel has integrated computation and the Windows environment in a superb manner. Finally, we have implemented several of the new compiler’s capabilities in our data interpolation algorithms. EMIGMA is quite unique in that it allows for rectangular grid cells, arbitrary grid angles and other aspects important for interpretation and resolution. These capabilities are particularly important for potential field data where the grids can be utilized for accurate Fourier processing as well as Euler depth estimation. Now, even the largest airborne survey can be gridded both accurately and in a time efficient manner.

Finally, we have implemented the new compiler, partially, for our freespace EM algorithms. These algorithms are for the inductive response of a thin conducting sheet. These algorithms are unlike other inductive plate algorithms in that they are not restricted to concentric current rings but allow a full expansion of induced currents in multiple geometries. This allows for accurate simulations of even long strike conductors but more generally for non-uniform excitation of the conductor which is most important for airborne systems which have large spatial gradients in the exciting fields. This type of excitation is not suitable for many freespace algorithms. Our algorithms are of two forms, one which is merely the freespace response and the other allows for the combination of an inductive response along with the response of a conducting host. While these algorithms do not allow for galvanic excitation (provided in another of our algorithms) it does include an important response even in resistive environments and that being the response of a conductive or weathered overburden. These improvements offer a 100 fold improvement in computation speeds.

Network Dongle
EMIGMA is license protected via a USB dongle. Previously, the dongle had to be connected to the computer upon which EMIGMA was being utilized. This was of significant inconvenience for institutions which had multiple users as the dongle had to be transferred from one user to another with the possibility that the dongle could be easily lost or stolen. Now, the network dongle may be installed on one secure system computer and utilized by users when the license is not being utilized by others. This type of license may be purchased for one or more simultaneous users. For information on how to convert your dongle to a network dongle please contact support.
