[CHiPPS] Blis install error

For some instances, you might not observe speedup, it depends the properties of the instances, machined used and algorithm implementation. Blis is not suitable for 2-processor-run because the Master doesn't processing nodes. It is designed for massive parallel computing (several dozen ~ thousands processors).  You need find the right machine to do the test.

You can check the CPUs usage to know how many processors are used.

What's the specification of your machine?

I have run some milp models in Blis 0.9, but I found that the more processes I use,

the longer run-time.

I run in this way:

mpiexec -1 -l -n 10 blis p0033.mps

                           Blis time         Blis time         Blis time
        cplex time     2 processes     6 processes    10 processes
p0033  0.04 sec      0.094985        0.280955        0.953854

                            Blis time       Blis time         Blis time
       cplex time     2 processes   10 processes    20 processes
bell5   0.85 sec        46.022         90                 111


Did I do something wrong ?

How to make sure that I really use the number of processes that are indicated
in the command line ?

Only by Alps0050I Launched number of  processes  ?

How to guarantee that the application program is really run in parallel on
different processors not on one processor ?

Any help is appreciated.

thanks

In log, you can find

I run blis in this way
mpiexec -np 2  blis -par blis.par -Alps_instance p0033.mps

I have attached the result .

how to verify that I really use 2 processor to solve p0033.mps in parallel ?

thanks

There is a similar var.par file in Blis/examples/VRP. You can adjust it for testing MILP.

I added a blis.par to Blis/test in the trunk version.

"make test" doesn't for MPI Blis. You have to manually test it. Please see the the INSALL file for details.

Hi,

I am trying to install Blis 0.9 on MPI cluster with MPICH2-1.0.8.

My configure:

./configure --prefix=/home/chipps_blics_svn_090422 --enable-static

--disable-shared -with-mpi-incdir=/home/jxding/mpich2_install/include

--with-mpi-lib='-L/home/jxding/mpich2_install/lib -lmpich'

MPICC=/home/mpich2_install/bin/mpicc

MPICXX=/home/mpich2_install/bin/mpicxx CXXDEFS='-DMPICH_IGNORE_CXX_SEEK'


configure: Configuration of Blis successful
configure: Main configuration of Blis successful

------------------------------------------------------

When I make test, I got error:
