If they are still the same process image (i.e. no execs), you could
mmap some ANONYMOUS|SHARED memory and wait on a flag byte with
atomic_cmpset(). Actually, writing to stdout should be atomic for most
writes (I have never seen gcc output garbled when doing parallel makes
for example).
The life span of each process is quite short (0.001s) and the system load
is fairly high (~40)
Thanks, your suggestion works. In fact flockfile also works if I
use cons25 instead of {x,ml,...}term. So the culprit may be X.

Do you have a testcase? The attached program mallocs 1 million
128-byte blocks, then frees them. With MALLOC_OPTIONS set to jz (i.e.
no filling of freed memory), it takes .184 seconds to free them all.
With it set to J, it takes 1 second.
CPU: Intel Pentium III (909.96-MHz 686-class CPU)
...
I changed your program a little bit to allow freeing the memory in
random order which is closer to what happens when hash tables are
deleted. The test program now allocates NUM pointers to SIZE byte
memory chunks and then frees them. RANDOM 0 means the order in which
the items are freed is the same as the order of allocation, while
RANDOM 1 means that the memory is freed in (somewhat) random order
The data below shows that freeing the memory is the bottleneck.
(MALLOC_OPTIONS JZ, using jz gives essentially the same results perhaps
about 25% faster)
My current guess is that the part copied below of the function
free_bytes in /usr/src/lib/libc/stdlib/malloc.c is to blame
where linked lists are traversed to move/delete pages whose
status has changed. At least that would explain the quadratic
behaviour in the output of the test program below.

memory allocation/deallocation (malloc experts needed)
My problem is essentially that freeing large numbers of small chunks of memory can be very slow. I have run into this problem twice so far. 1) Shutting down python can take several minutes if I have used large dictionaries. The solution I use here is to exit python without freeing the allocated memory (not really a good solution). 2) Freeing large hashtables in C. (No solution yet.) For these hashtables I can fairly easily divide the data into groups which could be deleted together. If I have all this data in one predefined region of memory then deleting them would be very fast. However in order to keep memory consumption as low as possible without sacrificing speed I am using Judy arrays (see the Judy project at source forge). But that means I have no direct control over how malloc is called. One solution would be to divide the memory in larger regions and to tell malloc which chunk to use for the next few calls, respectively when a whole chunk could be freed. But I don't know how to do this. Cyclone's regions seem to provide more or less what I need but cyclone works on neither CURRENT nor on amd64. Any suggestions where to look/what to read are greatly appreciated - Till ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

This got rid of everything in the file. I really need this back, so any help would be greatly appreciated. Unless you have a back up your file is lost. If you type: command FILE1a ... FILE1z FILE2 in your shell, then the shell does the following: 1) it creates an empty file with name FILE2. If there is already a file with this name it will be !ERASED! 2) it executes the command using FILES1a-FILE1z as arguments 3) writes the result into FILE2. In your case the shell erased your file index.html before it could use it as an argument to the sed command.

assembler, icc/gcc,
I am writing a program where speed is very important.
Some parts will probably have to be written in assembler.
I have a dual-Xeon machine running CURRENT.
I am looking for {advice on,experiences people have had with} writing
assembler programs for pentium4/xeon processors. (I have too many
manuals right now and difficulties in deciding where to start)
In particular, I am not sure whether I should be using nasm/icc or
gas/gcc. Nasm supports SSE2 instructions (I don't know if gas does,
the intel2gas port doesn't) which I probably need in order to
manipulate 81bit-500bit integers (sets) efficiently. On the other
hand I would like to be able to use inline assembler but that seems to
be impossible with NASM and gcc. I don't exactly know what style
of inline assembler icc supports yet.
Besides /usr/ports/lang/intel2gas there is a nasm-2-gcc-inline
translator at Fermilab http://lqcd.fnal.gov/sse/inline.html which I
haven't tried yet.
In any case any suggestions as to how to proceed would be appreciated.

trouble installing FreeBSD 5.1 on Vaio PCG-Z505VR/K and PCG N505
I run into the following problems trying to get FreeBSD5.1 onto the above
two laptops (neither of which has a built in floppy/cd)
Basic
I use a USB floppy drive.
(I only have a Panasonic KXL-808AN CDROM which is not recognized)
I used 4 sets of boot floppies ( so floppies should not be the problem)
Vaio PCG-Z505VR/K
I insert kern.flp and then mfsroot.flp, but then the kernel boots up to
umass1 and then the kernel panics.
The last lines are:
umass1: CBI reset failed, SHORT_XFER
umass1: CBI bulk-in stall clear failed, TIMEOUT
panic: Removing other than first element
Vaio PCG N505
kern.flp and then mfsroot.flp work (drivers.flp doesn't; the floppy
drive is not found any longer) kernel boots.
Trying to get to install the various distribution sets I get the
following problems:
network I tried many networks cards, some of them on the list of
supported hardware all refuse to configure the interface (ed1,wi0)
using DHCP
From a dos partition: I get dos partition not found.
I installed netbsd (installs without a hitch),
made a dos partition (using netbsd),
put the distribution sets in a directory /freebsd,
reboot with the boot floppies
select install from a dos partition
distribution sets not found or some such message (I forgot)
Since the {Free,Net}BSD naming schemes for hard drives differ
I had some problems for FreeBSD to recognize the dos partition
(it was hiding inside the NetBSD partition)
Please cc any suggestions you might have to me.
Thanks,
Till

curses header conflict
