I have some very basic and precise questions:
1) What programs must I have to run the INTEL IFC with open MP directives (parallelization) in Linux, and what Redhat versions (without tweaking and fiddling) will work? Will Redhat 8 work, what about 9 , and 7.3??Please specify the exact programs to use.
2) I have toyed with MPI, and will be building a cluster of 8 dual Xeons (headnode 2.8 GHz,7slaves 2.4 GHz with an extra single CPU Raid file server). One the other hand , openMP is sharing memory. Can the cluster system be configured (e.g. NPACI Rocks) to share "threads" with other processes not on the same motherboard;with HT technology, the maximum number of threads will be 4 , i.e. each physical computer will have 2 processors, and assuming 2 threads per processor, that gives 4. Can the threading be extended to other nodes, as with MPI??
3) Does openMP working with the specified software means that the computations must be confined to the motherboard, where memory is shared and held in common with the other processor.
Thank you. Please help. Chris Jesudason.
