xdnep testing of ScaLAPACK 1.7.4 ?

[hevensun]

The input data of NEP.dat is like this:


The following parameter values will be used:
N : 1024 1025
NB : 8 10 12
P : 1 1 1 2 5 2 7 1 4
Q : 1 2 3 2 1 3 1 8 2

Relative machine precision (eps) is taken to be 0.111022E-15
Routines pass computational tests if scaled residual is less than 100.00

but the testing has two failed!!!

How can I solve this problem? I used the f77 compiler and -O4 option.
Thanks!!!

Hi Hevensum,

Could you provide us some more details about your cluster/machine:

- processor
- inter-connect
- mpi version
- which f77 compiler?

and some information about your BLACS ans ScaLAPACK installation:

-the content of your Bmake.inc
-the content of yourSLmake.inc

and one more question: did you run the BLACS tester?

Thanks
Julie

the machine is HP-SC 45
the processor is alpha;
mpi version is mpich
compad f77

And I rum the BLACS tester also. There is no problem with xsnep,xcnep.xznep ,but two failed in xdnep.
the content of Bmake.inc is:
