...l very appreciate, if you have any ideas concerning the problem described below. First, I'd like to describe the model in brief. In general I consider a model with three equations. First one is for annual GRP growth - in general it looks like: 1) GRP growth per capita = G(investment, migration, initial GRP per capita, spatial lag on GRP growth + some additional explanatory variables to control for regional disparities), where spatial lag on GRP growth in year t is simply spatial weights matrix W(n*n) (weights - are inverse square distances between regional centers; with zeros o...

HI, T5220, S10U4 + patches mdb -k > ::memstat While above is working (takes some time, ideally ::memstat -n 4 to use 4 threads could be useful) mpstat 1 shows: CPU minf mjf xcal intr ithr csw icsw migr smtx srw syscl usr sys wt idl 48 0 0 1922112 9 0 0 8 0 0 0 15254 6 94 0 0 So about 2mln xcalls per second.

In crossbow, each mac_srs has a kernel thread called "mac_rx_srs_poll_ring" to poll the hardware and crossbow will wakeup this thread to poll packets from the hardware automatically. Does crossbow provide any method to disable the polling mechanism, for example disabling the this kernel thread?

...y reason for this nor systematics in when the servers would lock up. The solution is now available: Upgrade your IBM servers to the latest Broadcom firmware released by IBM on May 21, 2007 ! The IBM web-page is at http://www-304.ibm.com/jct01004c/systems/support/supportsite.wss/docdisplay?lndocid=MIGR-53693&brandind=5000008 There is no hint what Broadcom did to solve our PXE problem, but the menu.c32 certainly works without any glitch now. It should be noted that we have also upgraded the system BIOS to the latest release, but I haven't determined if the BIOS level has any influence on...

I have been using PXELINUX for a while and appreciate all you guys are doing! I have a couple of questions re PXELINUX: 1. I am experiencing problems with the LOCALBOOT statement on an IBM x3650. IBM mentions the following: http://www-947.ibm.com/support/entry/portal/docdisplay?lndocid=MIGR-5084755 I am using PXELINUX 4.04. Is this problem still attributed to some bug in PXELINUX? Right now I am using the work-around of using chain.c32 with the append hd0 parameter. But this solution skips the BIOS boot sequence. 2. Is there a plan to make an EFI version of PXELINUX? Regards, Octa...

I just had a quick play with gzip compression on a filesystem and the result was the machine grinding to a halt while copying some large (.wav) files to it from another filesystem in the same pool. The system became very unresponsive, taking several seconds to echo keystrokes. The box is a maxed out AMD QuadFX, so it should have plenty of grunt for this. Comments? Ian
