They have always been too small. We have a customer, who moved from linux, who prefers to spawn parallel MPI jobs on his cluster using our simple spawning script rather than a spawning daemon (like mpd, or those provided by most batch queue systems). Picture the fun we had trying to get more than 1000 persistent ssh connections established to every CPU on the cluster. Even though it is inadvisable to do this, it should still be possible (and it does work fine on linux). Drew _______________________________________________ Do not post admin requests to the list.

When you click on it, a dashboard widget is created. This email sent to site_archiver(a)lists.apple.com

Re: Darwin 8.0 Source Code Available

site_archiver(a)lists.apple.com Delivered-To: Darwin-dev(a)lists.apple.com Does the fact that the released Darwin 8.0 source code requires gcc 3.3 to build imply that the kernel in Tiger itself is currently being built with gcc 3.3 as well rather than gcc 4.0? If so is there a plan to transition to building the Tiger kernel with gcc 4.0 in the 10.4 development cycle or will that be put off until 10.5?

Of course and it's there that it's related to darwin is that all of this occurred because at one point, there's a bunch of "can't fork" error. Now, the real question is: is it logical that you can screw a user session that easily? Shouldn't there be a limitation on the number of processes that could be run by dashboard? aren't kern.maxprocperuid and kern.maxproc (I think it's these sysctl values) too small now that dashboard is in town?

Darwin-dev mailing list (Darwin-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-dev/site_archiver%40lists.app… Just a quick update, running Essentials.pkg borked my system upon reboot. Half of my apps didn't run anymore and gave a shared library error with Carbon. I tried a fresh clean install of 10.4 and now vmmap is where it should be. I have filed a report about the upgrading issue. I loaded up the Essentials.pkg and ran it. It reported that there were errors in installation which was kind of unnerving. However, vmmap is now back again which make me happy. I will keep an eye out for any side effects. I have not yet tried a fresh install of 10.4 on any machine yet, but I plan on doing one soon. If anyone else has seen a similar behavior in upgrading from 10.3 I will probably file a report. Thanks for the help! On 10.4, it seems to be in Essentials.pkg: hc652a8d4:~ jdurham$ lsbom /Library/Receipts/Essentials.pkg/ Contents/Archive.bom | grep vmmap ./usr/bin/vmmap 102555 0/2 40980 1597189142 ./usr/share/man/man1/vmmap.1 100644 0/0 6705 1971577080 This was a clean install, so maybe something happened during the upgrade? One more quick question. I may be missing something here, but after upgrading I can find no sign of vmmap on either of the machines that I have upgraded to 10.4. I checked on a 10.3 machine and it normally resides in /usr/bin. I can imagine that there are some updates that have yet to be made to it for Tiger and that we might see it back soon. Anybody have any info on this? Is the source available anywhere? Thanks. Spencer Nielsen _______________________________________________ Do not post admin requests to the list. They will be ignored.
