I decided to try OpenBSD-sparc64 on my Sun T2000 (Niagara T1, 32 threads, 16G RAM). CD install of 5.7 went fine, pkg_add installed git vim and gcc from official mirro fine.
Now as a test (to compare oranges to oranges) I tried to check out Linux kernel git repository but that ran out of memory: $ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git Cloning into 'linux'... remote: Counting objects: 4153047, done. remote: Compressing objects: 100% (1931/1931), done. remote: Total 4153047 (delta 1105), reused 0 (delta 0) Receiving objects: 100% (4153047/4153047), 921.61 MiB | 1.11 MiB/s, done. fatal: Out of memory, malloc failed (tried to allocate 40960 bytes) fatal: index-pack failed The server had more than 15G RAM available. This command fails on 64M RAM but works on different 128M-256M machines fine (with Linux). ALso tried hackbench from http://people.redhat.com/mingo/cfs-scheduler/tools/hackbench.c to run the same benchmark as in Linux and Solaris: /hackbench 150 process 1000 Running with 150*40 (== 6000) tasks. fork() (error: Resource temporarily unavailable) Out of memory in fork() too. After that, fork() fail for everything. dmesg of a fresh boot is included below (nothing in /var/log/messages). Am I missing something about OpenBSD sparc64 memory management? I can give a developer access to the machine (and its ILO) via ssh if this is unique enough. console is /virtual-devices@100/console@1 Copyright (c) 1982, 1986, 1989, 1991, 1993 The Regents of the University of California.
