Hello

I am using a program and it is running very well in single mode but if I try to run it in multi mode, via TBB, I found the following error message:

On entry to ZLASCL parameter number 4 had an illegal value

Need your help.

Thanks in advance.

Yes Bessier Romero , this particular error message often generates when ZLASCL founds the CFROM “zero” or it has a NaN valued assigned into it. This could also happen because of the ARPACK code which is written in FORTRAN and cannot be executed simultaneously with ZLASCL. All you need is to set your application to use one thread instead of going for multiple codes at a time.
