[Scilab-users] Scilab 5.5.2 in Debian 10 - segmentation fault

Hi All,
In order to use Scilab’ parallel_run in Debian 10 (x86_64),
i download
https://www.scilab.org/download/5.5.2/scilab-5.5.2.bin.linux-x86_64.tar.gz
unpack it to
~/foo/scilab-5.5.2
then
cd ~/foo/scilab-5.5.2/bin
and run …
 
$./scilab
 
Segmentation fault
:((
 
? What am I doing wrong ...

I faced segfault problem with really basic matrix use in Scilab 5.3 and I guessed mismatch somewhere (Scilab, Java, OS?) in multicore system, but I was not able to investigate more. My solution was to use scilab 6.1... It works now with complex matrix use.

Re: Scilab 5.5.2 in Debian 10 - segmentation fault

In reply to this post by AndreiL

Hello Andrei,

I think this is a dead end.
As far as I remember, parallel_run only works on Windows, on 1 core and is an ugly hack.
From https://help.scilab.org/doc/5.5.2/en_US/parallel_run.html :

"In this current version of Scilab, parallel_run uses only one core on Windows platforms."

Can you tell us a bit more about what you try to do?

Cheers,

Antoine

Hello Andrei,

 

To launch the Scilab 5.5.2 binary on new Linux version, you might need to remove some libraries (so files) provided by your system. Especially, you could remove the scilab-5.5.2/lib/thirdparty/libz.so.1 file which is provided by your system.

 

Regards,

 

Clément

Re: Scilab 5.5.2 in Debian 10 - segmentation fault

Hello Clément,

I forgot that detail.
But this will not help Andrei use parallel_run, as it does not work under linux, right?

Cheers,

Antoine

Re: Scilab 5.5.2 in Debian 10 - segmentation fault

Hello Antoine,

 

It should run on Linux using 5.5.2 (as fork() is available) however if parallel work is needed I suggest you to use Scilab MPI rather than parallel_run. The former is process based with explicit variable transfer whereas the latter is implicit.

 

See https://help.scilab.org/docs/5.5.2/en_US/MPI_Recv.html for more information.

 

Thanks,

 

Clément

Re: Scilab 5.5.2 in Debian 10 - segmentation fault

In reply to this post by Antoine Monmayrant
It’s exactly the opposite. It does work with 5.5.2 under Linux but does not with  5.5.2 under Windows.
