Essential Information about Flux 2021
| Essential information about Flux 2021 |
|---|
In order to use the version HWU, you need:
|
Flux 2021 is available for Windows and Linux OS:
|
|
The Linux version is qualified with the Gnome Classic with X11 display server. It is highly advisable to use the Gnome Classic with X11 display server to run Flux on Linux. |
| Flux 2021 takes into account the feedback from several users, and around 30 customer issues have been fixed in this version. |
| The Dynamic memory management already available via an option
in the Supervisor in beta version in Flux 2020.1, is now in
standard version in Flux
2021. see more details Warning: The dynamic memory working process (with memory
allocation/releasing) has a light impact on the performances. If
you notice an abnormal execution time with dynamic memory (and
not in static memory), you can contact the support (code
optimizations are possible). The default memory mode is still
set to User but we encourage you to use
the Dynamic mode extensively and give us feedback. We
plan to continue working on the robustness an the performance of
the dynamic memory, our goal being to have the Dynamic
mode by default for the next Flux 2021.1 release.
Warning: All Flux algorithms work now with dynamic
memory, except Delaunay mesher (not default mesher). Only
MeshGems mesher is available in Dynamic
memory. If user wants to use specifically Delaunay,
he has to switch to User (or static)
memory in supervisor options.
|
| Distributed computing with MPI is available in Flux for Windows and Linux and can be used with PBS. However, qualification on Windows cluster connected with InfiniBand has not been done and Linux clusters are highly recommended for parallel computing. |
| It is now possible to install Flux on Windows or Linux without administrator rights with limited functionalities. |
| About CDE Licensing: Before using
CDE, please check that the environment
variable for the license: ALTAIR_LICENSE_PATH is set
as system environment variable.
Warning: If
ALTAIR_LICENSE_PATH is set as user
environment variable only, CDE will fail. For CDE to work properly,
ALTAIR_LICENSE_PATH environment variable must
be set as system environment variable.

The "CDE" and "CSS"
services do not start if there are too many files in the root of the
%TEMP% directory. Please if it is the case,
clean this directory, reboot and launch the batch
script: Bin\prg\win64\Active_Distributed_Computation_and_API.bat |
| About the CDE/CSS user temporary directory
%TEMP%: (The user temporary directory is by default: C:\Users\<username>\AppData\Local\Temp) If
there are a lot of files in the user temporary directory (according
to our tests, "a lot" means more than 50 000 files, but it could be
lower or higher on your computer), then CSS
and CDE services will not start. In order to
fix this issue, please follow the procedure described below:
