Hi,

I have benn testing the scalapack 1.7.4, and met with some problem as followings. I used

machine is HP-SC 45

compad f77 -O4

mpich

blacs tester all passed

I tested all the exe, most of them have been passed,but there are some exe doesn't work with some specific input data , they are xsllt ,xdllt,xsinv,xdinv. I traced xsllt and xsinv , they are all hanged up at pspotrf() function and maybe xdllt and xdinv have the same problem. It seems that at grid 1*2, when the matrix order is large ,for example is 1024, it doesn't seem to work. Is there some bug in pspotrf() funcion?

the INV.dat is :

'ScaLAPACK, Version 1.0, Matrix Inversion Testing input file'

'MPI machine.'

'INV.out' output file name (if any)

6 device out

1 number of matrix types (next line)

'UPD' 'LPD ' GEN, UTR, LTR, UPD, LPD

1 number of problems sizes

1024 values of N

2 number of NB's

1 2 3 4 5 values of NB

1 number of process grids (ordered P & Q)

1 1 values of P

2 3 values of Q

100.0 threshold

and the LLT.dat is :

'ScaLAPACK, LLt factorization input file'

'MPI machine'

'LLT.out' output file name (if any)

6 device out

'U' define Lower or Upper

1 number of problems sizes

1024 1025 values of N

5 number of NB's

1 2 3 4 5 values of NB

2 number of NRHS's

1 3 9 28 values of NRHS

2 number of NBRHS's

1 3 5 7 values of NBRHS

1 number of process grids (ordered pairs P & Q)

1 1 values of P

2 3 values of Q
