Random notes

• Acronyms and concepts
• "Global Grid Forum (GGF) is the IETF for grid computing"
• Ian Foster and Carl Kesselman are 'fathers' of the grid
• gLite 1.5 released on 2006-01-20, gLite 3.0 released on 2006-05-04
• OpenMPI = OpenMP (OpenMP is shared-mem, OpenMPI distributed-mem)
• Using VOMS (gsissh) at JMS-level (i.e. Torque, LSF, ...)? YES! Because the LCG Technical Design Report states:
• From NIKHEF meeting notes may 8 2006: "Oscar sent document to GGF on proposed standard definitions of LDAP strings"
