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++

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

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.

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!
