Subject: Hoard 1.2 - malloc/free replacement: 30% faster + SPROC support
Date: Sun, 31 Oct 1999 08:43:23 GMT
=====BEGIN PGP SIGNED MESSAGE=====
Hoard is a fast, scalable, and memory-efficient replacement
for malloc/free for multiprocessors. The newest release (1.2)
incorporates a user-level lock implementation (for x86, SPARC,
and SGI's) that improves performance by about 30%. This makes
Hoard faster than the Linux allocator in glibc2, even on just
one processor (it's always been faster for multiple processors).
This version also includes an "sproc" version for SGI's.
<http://www.cs.utexas.edu/users/emery/hoard>
Looks like some work has to be done for AIX, HP-UX and others. Anyway,
would be interesting to know how this compares to other implementation
on e.g. AIX/HP-UX.

Uh, unless somebody made XEmacs multithreaded while I wasn't looking,
this sort of technology isn't very interesting... The problem that
MT allocators are attempting to solve is concurrent access to the heap
management structures internal to the allocator itself.
That said, if someone is inclined, experiments with various allocators
with an eye to performance will perhaps uncover

In my last posting, I accidentally sent before finishing a thought
which I don't really have time to complete right now. So, just ignore
that last paragraph (which probably doesn't mean anything anyway).
