PVM tesztelése IPv6 környezetben
PVM
Az Euro6IX projektben készült egy patch a PVM-hez ami lehetővé teszi az IPv6 müködést: http://www.ngn.euro6ix.org/IPv6/pvm/ A projektben ezt
PVM 3.4.4
Letölthető:
http://www.netlib.org/pvm3/pvm3.4.4.tgz
IPv6 patch elérhető innen:
olvashato formaban: pvm3-3.4.4-v6-23042005.diff.txt
és müködik is vele, de a projektben a legfrisebb változatot is megvizsgáltuk.
PVM 3.4.5 (latest release)
Letölthető:
http://www.netlib.org/pvm3/pvm3.4.5.tgz
IPv6 patch:
Megpróbáltuk a 3.4.5-s pvm-t patchelni a 3.4.4-es diff-el. Eredménye az alábbiakban látszik:

Látható, hogy a 3.4.4-es diff fájl nem teljesen jó a pvm 3.4.5-höz - egyetlen helyen nem volt lehetséges 3.4.4-hez készített patch-et alkalmazni.

Értékelés
A teszt eredményekből látszik, hogy a PVM IPv6-on kommunikál. Annyi a szépséghibája, hogy ebben az esetben csak és kizárólag IPv6-on képes beszélni, IPv4-en nem. A program forditásakor tulajdonképpen egy kapcsolóval kell megadni, hogy IPv6-ot, vagy IPv4-et szeretnénk használni:
roczei@knowarc1:~$ export PVM_RSH=`which ssh` roczei@knowarc1:~$ cd pvm3 roczei@knowarc1:~/pvm3$ export PVM_ROOT=`pwd` roczei@knowarc1:~/pvm3$ make CFLOPTS="-DINET6"
Abban az esetben, ha meg van adva a CFLOPTS="-DINET6" kapcsoló, akkor IPv6, ha nincs megadva, akkor IPv4 alapú lesz.
