Hi Daniel, thank you for your reply, as far as I understand you mean Beowulf cluster based on MPI/MPICH/PVM. It is a very good sign. Maybe in near future some one could manage to make next step and setup SSI cluster (based on OpenMOSIX or OpenSSI). Then one could obtain implicit parallelization on Opteron-based clusters as well. Unfortunatelly it looks for me like today SSI are not really ready for neither for ia64 CPUs nor SUSE9 few remarks: Remark1. OpenMOSIX ia64 port activity: https://sourceforge.net/pm/task.php?group_project_id=19284&group_id=46729&fu nc=browse BTW, July 16, 2003 Moshe Bar has told (http://www.linuxjournal.com/article.php?sid=7007): --------- LJ: openMosix is starting IA-64 porting. What is your comment on the process? Do you think the porting will be smooth? How about porting to Opteron (AMD 64 bit)? How will you manage these two ports? MB: We actually have finished porting to IA-64. We will now decide whether to port to Opteron or to Itanium 2. It depends on how much contribution we can get from either team. --------- ...but sourceforge still shows ia64 Port activity... how then? Remark2. OpenSSI ia64 Port to IA64 is led by John Byrne and I don't know if it is trackable and dont know the status. Remark3. I've fail to install both OpenSSI and OpenMOSIX even on my Linux SUSE 9 for ia32. I do like SUSE distribution, but i think i have to consider RH9 to get SSI cluster running :( -- Valery
