Dear all,
I am working with an example of petsc-3.2-p5/src/ts/examples/tutorials/ex15.c
I noticed that in ex15.c,
Jtype == 0 means that /* use user provided Jacobian evaluation routine */
Jtype == 1 is for /* slow finite difference J; */
and Jtype == 2 is /* Use coloring to compute finite
Feng-Chao,
Jtype == 1 is for /* slow finite difference J; */
computes dense Jacobian one column at a time, taking prohibitively
long time for large
matrices. For 101*101 matrix, i.e., it evaluates 1.e+4 columns
(evaluate function 1.e+4 times).
Running it on my Mac, the execution terminates after a
in advance!

Hello,
I've installed PETSc 3.2 and SLEPc 3.2 on Mac OS 10.7 through MacPorts
2.0.3. PETSc works fine by itself, but SLEPc fails on the initial
EPSCreate call. The error follows.
This is presumably a MacPorts misconfiguration issue, but thought I'd
check here first to see if anyone has seen
