Hi there,<br>
<br>
Some time ago I built a PETSc (3.0.0-p9) on the BG/P down at NZ's<br>
Univ of Canterbury, for a researcher here at VUW who wanted to<br>
run the PISM ice-sheet modelling code on top of it, and in the<br>
process discovered that the version installed by the sys admins<br>
at the facility was buggy, so the researcher carried on compiling<br>
later PISMs against my 3.0.0-p9.<br>
<br>
UoC are in the process of upgrading to a BG/P and the researcher<br>
has asked me to see if I can coddle things together, is keen to<br>
run with what he had before and is under "time pressure" to get<br>
the remaining results needed for a paper, so is hoping I can<br>
install something ahead of the facility's sys admins install<br>
a system wide version.<br>
<br>
Notwithstanding the obvious upgrade in release of PETSc from our<br>
3.0 series to the current 3.2, I notice that the petsc-bgl-tools<br>
wrapper package only (not surprisingly I guess, given the bgl bit)<br>
provided for IBM 7.0 and 8.0 compiler suites, so, have you guys<br>
tried out PETSc on a BG/P yet?<br></blockquote><div><br></div><div>BG/P has been out for a while, so of course people have been running PETSc on it for years. You can look at</div><div><br></div><div>config/examples/arch-bgp-ibm-opt.py</div>
