Default behavior of OPENBLAS_NUM_THREADS?

[Zongheng Yang]

Hi All,

I am using JBlas that was built using OpenBlas from within a Java program. If I launch the program without exporting the flag OPENBLAS_NUM_THREADS, is using all threads that are available on the machine the default behavior? 

Thanks,

Zongheng

If it helps, I am trying to run the Java program on an Amazon EC2 m3.2xlarge instance machine.

Hi Xianyi,

Thanks! A small suggestion: it'd be great if this can be documented in
here (https://github.com/xianyi/OpenBLAS/wiki/faq#multi-threaded) for
the new comers.

Hi,

I am trying to use jblas with OpenBlas. It seems that you did it. Could you explain the steps, please? How can you build a jar file?
