[CHiPPS] ChiPPS error run

[Yan Xu]

 "mpiexec -np 2 blis -par p0548.mps" is not the correct way. You need something like

                     mpiexec -np 2 blis -par blis.par -Alps_instance p0548.mps

Please refer to the INSTALL file about how to build and run Blis. You can specify which instance to run in the blis.par file, or in the command line.

Regards,
Yan

Subject: [CHiPPS] ChiPPS error run

Hi,

I have installed Blis-0.9  and try to run it on a cluster with MPICH2.
I am using 2 processes to run the benchmark  bell5.mps, which is a mixed
integer linear programming.

ftp://ftp.caam.rice.edu/pub/people/bixby/miplib/miplib3/bell5

I got error :

--------------------------------------
mpiexec -np 2 blis -par p0548.mps

--------------------------------------
Why Blis say that he Problem does not have integer variables ?
bell5 has 58 integer variables.

Any help is appreciated.
