so in order to support Atlas a site administrator needs to install
several SLC4 RPMs???
This sounds weird, if not outright wrong to me. If Atlas needs certain
(system) libraries then they should either ship these libs themselves
(heck, they're including ld-2.3.4.so, libc-2.3.4.so and libpcre.so.0.0.1
anyways; might as well stick in libgfortran.so ;-)) or they should lists
which libraries their software is dependent on, not which RPMs.
64bit WNs in combination with SGE as a batch system is already certified
as a valid batch system; I must say that I have not attempted a WN_tar
installation on SuSE but in general the "WN tar-ball running on X86_64"
is an option that we intend to support (within SA3 Batch System
Integration).
