Hi all, Can an UML process run on multiple processor? I thought to use an HPC clustering system for processes migration between two machines. Since UML is an (user mode) process, could it be migrated from a cluster to another one? Can I benefit of an HPC clustering system to increase performances? I thought to run UML using OpenSSI cluster, is there anybody here who found some trouble doing that? Thanks a lot, Flavio |

Sure, if your cluster can migrate processes, it should have no trouble with UML. Jeff -- Work email - jdike at linux dot intel dot com |

I'm not that familiar with OpenSSI or how SKAS3 works, but wouldn't =20 they conflict? I seem to recall being told (quite) a while back that =20 UML wouldn't run on Mosix (not that OpenSSI is Mosix)... presumably =20 for some SKAS related reason??? Could someone possibly elaborate? I looked at the Powerpoint =20 presentation[1] about OpenSSI, and it seems that there may be a =20 likely patch overlab in the Vproc and SKAS support?

My first idea was to try OpenMosix to boast UML actually, but since OpenMosix is no longer developed and supported, I had to try another HPC system. It is not properly the same, I know, but I'll try. I hope there won't be conflict problems, as Cameron said, about SKAS support and OpenSSI (If I correctly understand what she/he means). In any case I'll try that for sure. Thank you, Flavio |
