[Zope-dev] ZEO on SMP

2001-05-23 Thread Dyon Balding
Hi, We are setting up a cluster of ZEO clients on dual processor machines. From some experiments and from searching through the mailing lists, it appears that a single Zope process will not take full advantage of the two processors. The solution would appear to be to run two ZEO clients on

Hi Dyon, ZEO on a dual processor machine runs fine for me. I'm using redhat-linux for the server (ZEO and Clients on same machine) If you dont need strange things I would not recommend Win2k as server platform. Best regards Tino Wildenhain --On Mittwoch, 23. Mai 2001 11:35 -0700 Dyon Balding

Tino, Thanks for your reply. When you say it works fine on a dual processor machine, are you saying that a single ZEO client fully utilises both processors? or that you are running two ZEO clients successfully? Unfortunately I'm currently stuck with Windows due to both political reasons, and

They are listening on different ports, (80 and 81) in my test case. And yes, there will be a load balancer in front of them (there will be 15 dual processor servers) to make the cluster appear like one machine. -dyon On Wed, May 23, 2001 at 12:38:25PM -0700, Randall F. Kern wrote: If I

Since a single Python process has a single global interpreter lock, you'll never fully utilize a 2-processor machine. The lock is released whenever a socket call (send, receive, listen, etc.) is made, so that provides some opportunity for using two CPUs, but not much. Jeremy

Well that's what I'm trying to do, but as mentioned in my original post, any Zope clients utilising ZEO started after the first one do not respond. The ZEO storage server is running on a separate machine, serving the 15 client machines. -d On Wed, May 23, 2001 at 05:51:57PM -0700, David Brown
