I. What computer do I need to run PaleoScan™?

PaleoScan runs on PCs, laptop, desktop or workstation. PaleoScan does not run on Mac computers. PaleoScan can also run on Virtual Machines.

II. What operating system do I need to run PaleoScan™?

PaleoScan requires Windows 64-bit version 7 or above.

III. What hardware do I need to run PaleoScan™?

The minimum /recommended hardware configuration to run PaleoScan is:


IV.What are the recommended settings for I/O and RAM in PaleoScan?

The recommendation for the percentage of physical memory allocated to PaleoScan is to keep the 30% default value for a machine with at least 16GB of RAM.

The “Temporary Directory” stores intermediate volumes computed by PaleoScan. The “Temporary Directory” does not need to be at the same location than the PaleoScan project and can be set by the user. It must however have at least 3 times the size of the seismic volume of free space.


V. What are the recommended settings for CPU/GPU in PaleoScan™?

The recommendation for GPU usage is to select the graphic card and for the CPU usage is to keep the default number of threads. Note that enabling the GPU parallelization will not dramatically increase Paleoscan’s performance except for the Properties Modeling module.

CPU parallelization is widely used in PaleoScan but GPU acceleration (using OpenCL technology) is currently used only in the Properties Modeling module and for some attributes computation, such as similarity. When both are enabled, GPU is used instead of CPU for the processes that support GPU. The other processes that do not support GPU but CPU parallelization run faster when CPU multithreading (several threads running on the same CPU) is enabled. However, all the threads are processed on the machine running PaleoScan and share the machine’s memory. Threads cannot be processed separately on different CPUs and memories. Paleoscan’s tasks (Geo-Model, attributes computation...) can only be started from the PaleoScan GUI (Graphical User Interface) as single executables. Distributed environments, with several physical machines with separated memory and CPU, are therefore not supported. 

Our internal benchmarks show that PaleoScan’s performance does not increase linearly with the number of cores used: 8 cores will definitely improve the performance but it will peak at 16 cores and even decrease beyond 16.

VI. What is the optimum IT environment to run PaleoScan?

PaleoScan accesses hard drives intensely for reading from and writing to the flat file database. Therefore, PaleoScan therefore works optimally when Input/Output to hard drives is optimized, either by working locally or through a network with the application and the memory disks at the same physical location. Using Solid State Drives with increased I/O speed will also improve performance.

VII. How does PaleoScan handle 8-bits/16-bit data?

PaleoScan can import 8/16 bits Segy data and then keeps the original data size. However, almost all the steps of the PaleoScan workflow will create 32 bits volumes (attribute computation, Model-Grid...). As a result, the output volume size is bigger (x2 if 16 bits, x4 if 8 bits) than the original volume.

VIII. I have 3D display issues (such as all my objects are black in the 3D viewer), how can I fix it?

It is probably a graphic card issue. The user needs to check in the computer settings that the right graphic card is assigned to PaleoScan™.

IX. I cannot access the functions of my add-on module license (Advanced Interpretation, Properties Modeling, Time/Depth, OpenWorks®).

The add-on module needs to be activated through an extension available with a specific license.

Go to the Extensions menu and click on the add-on module(s) to activate them.



X. I have an error when trying to run PaleoScan, saying that I have an obsolete Flexnet deamon, how can I fix the issue?

The latest PaleoScan uses an updated Flexnet License system. This implies that the license server needs to be updated, the Eliis daemon can be found:
