We're trying to work out memory limits for 32-bit versions of SL4 and 5. Redhat's page (http://www.redhat.com/rhel/compare/) says that the maximums are 64GB or RHEL4 and 16GB for RHEL5 (I guess because they dropped the HUGEMEM kernel RPM in RHEL5).
This page (http://www.scientificlinux.org/documentation/misc/limits) says that it's 64GB in SL4 but gives no information for SL5. So two questions: Does SL4 i386 have a 'HUGEMEM' kernel build or do you just build those features into the normal -smp kernel build in order to support 64GB RAM? What is the memory limit on SL5 i386? Thanks Tim Edwards
