Loading parallel udf
 

Hi,

I got some problems loading a parallel udf. When I try to compile the udf, averything works well, but , when I load it I got this error:

************************************************** ********** Primitive Error at Node 0: open_udf_library: No such file or directory connect to address 152.74.25.116: Connection refused connect to address 152.74.25.117: connect to address 152.74.25.116: Connection refused trying normal rsh (/usr/bin/rsh) Connection refused connect to address 152.74.25.118: Connection refused connect to address 152.74.25.117: Connection refused trying normal rsh (/usr/bin/rsh) connect to address 152.74.25.118: Connection refused trying normal rsh (/usr/bin/rsh)

Primitive Error at Node 3: open_udf_library: No such file or directory ************************************************** ***********

We've changed the fluent's scrip file changing rsh by ssh, and rcp by scp because we want to use only ssh as a communicator.

When we run a case without udf's ,our linux cluster works well, but , when we try to run a case that has to use udf's it doesn't work.

bye, thanks in advance.

check the linker udf c++

Re: Loading parallel udf
 

please add \\computername/libudf_directory in your libudf directory. in addition, you must share your libudf_directory to all cluster computers.

wish to have some help for your problem!

thanks,

I already fixed it. Now it works. The key thing was with the environmental variables. if anyone needs some information related, just let me know

same error loading udf
 

Hi pablo cornejo
I already ran in to a same problem. the udf compile well but it ran in to the same error when I load it. what did you do exactly about the environmental variables?
thanks anyway.

same problem
 

Hi!
I'm try to running a parallel fluent on a LINUX Cluster.
My case contained a UDF about DPM. It can be compiled successfully without any Error. But when I loaded it, the same problem occured:

Primitive Error at Node 0: open_udf_library: No such file or directory.
Primitive Error at Node 1: open_udf_library: No such file or directory.
...

Someone said there was something wrong about Enviroment Varibles. So I launched fluent with parameter -env. But I just don't know how to check the problem. Anybody knows details about this? or solved this problem?

I found many people had the same question with me. but no conclusion.
THANKS A LOT IN ADVANCE!! lich

Great! It works.
Just change the path of directory "libudf" into absolutely path like "/home/.../libudf" when you compiling and loading the source file.
THANKS!

Pablo I have the same problem, please help me!
