2 // Knonw Bugs:
3 // Fails in test #6
4 // Tested only on SuperLU.rua
5 // Monstrously too many prints
6 // Fails on an assert when teseint glarger matrix
7 // Also in test #6 - try without test #6
8 //
9 // Epetra_CHK_ERRs look like negative values on return - and hence
10 // look like Amesos_Scalapack is not built in.
11 // PROPOSED SOLUTION: Set a BUILT flag for each AmesosClass
12 // verbose is not controlling print outs from Amesos_Scalapack -
13 // they are always on -DONE
14 // Failue in PDGETRS - FIXED
15 // debug is not being turned off in Amesos_ScaLAPACK - FIXED
