[Xen-devel] [PATCH 0/6] xen,xend,tools: Add NUMA support to Xen
I''ve respun the NUMA patches against 10874 and I''m re-submitting them with the optimizations mentioned [1]previously on the list. There was a request to see the overhead on non-numa/single-node machines. I''ve re-run those benchmarks (ballooning up from small mem to multi-gig) as well as timing the initially domain increase_reservation time to gauge the overhead when allocating from the heap. The results for these were done on an x460, single node, with 6G ram. The balloon test was from 512M to ~6G. The NUMA patches include all of the previous optimizations. Balloon Up: Without NUMA With NUMA NUMA Delta Try1: 2943ms 2937ms -6ms Try2: 2996ms 2992ms -4ms Try3: 2971ms 2968ms -3ms Increase reservation Without NUMA: MemSize 128M 512M 1G 2G 3G 4G ------------------------------------------ Try1: 10ms 38ms 76ms 160ms 237ms 308ms Try2: 9ms 37ms 76ms 151ms 232ms 308ms Try3: 9ms 37ms 76ms 151ms 226ms 311ms With NUMA: MemSize 128M 512M 1G 2G 3G 4G ------------------------------------------ Try1: 10ms 42ms 84ms 170ms 260ms 346ms Try2: 10ms 42ms 83ms 167ms 255ms 346ms Try3: 10ms 42ms 83ms 168ms 251ms 346ms The only other change has been to the infrastructure patch in which I added the call to Xen''s command line parsing to pick up the numaoptions. This allows even on NUMA systems to disable NUMA parsing and fake the number of nodes (numa=off fake=1, would fake 1 node). 1. http://lists.xensource.com/archives/html/xen-devel/2006-07/msg00384.html -- Ryan Harper Software Engineer; Linux Technology Center IBM Corp., Austin, Tx (512) 838-9253 T/L: 678-9253 ryanh@us.ibm.com _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

In asm-x86/topology.h, you wrote: extern unsigned int cpu_to_node[]; extern cpumask_t node_to_cpumask[]; #define cpu_to_node(cpu) (cpu_to_node[cpu]) #define parent_node(node) (node) #define node_to_first_cpu(node) (__ffs(node_to_cpumask[node])) #define node_to_cpumask(node) (node_to_cpumask[node]) I think cpu_to_node and node_to_cpumask must be either a variable or a macro, but not both! (ia64 defines cpu_to_node as a macro). Tristan. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Either use an if statement or a variable assignment: op->u.availheap.nr_nodes = ( op->u.availheap.node < 0 ?) num_online_nodes() : 1; Tristan. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Furthermore you define the variable in xen/numa.h: extern unsigned int cpu_to_node[]; #include <xen/cpumask.h> extern cpumask_t node_to_cpumask[]; Which one is the API ?

For DOM0_PHYSINFO, sockets_per_node is wrong: pi->sockets_per_node = num_online_cpus() / cpus_weight(cpu_core_map[0]); [On ia64, I return the max of sockets per node]. The node_to_cpu field of struct dom0_physinfo is: XEN_GUEST_HANDLE(u64) node_to_cpu; This means the max cpus is 64. I know cpumap_t is also 64 bits. I think you''d better to use cpumap_t. Here we have NUMA machines with 128 cpus. The question is how to upgrade Xen to handle more than 64 cpus. We can either incease cpumap_t size to 256 (until we reach a new limit) or use an unlimited cpu structure.

RE: [Xen-devel] [PATCH 0/6] xen, xend, tools: Add NUMA support to Xen Issues on the ES7000
Ryan,
I tried out these patches on an ES7000.
It''s an x86-64 two-node machine with 16 procesors and 32 GB of memory
total.
I applied all of the six patches you had posted to the latest changeset
as of today(10946:e1a2a8029e9f).
Xen finds the SLIT and SRAT tables. I was able to bring up and down
multiple DomUs.
I then tried running a set of tests (bringing up domus and running LTP
and Kernbench) and I found that the system was hanging. It wasn''t
crashed (I could ping it etc). But it was running so slow that ssh
wouldn''t work, even though I could use telnet to get on port 22.
I found out by accident booting into Dom0 and starting xm top hangs the
system in a similar fashion.
Nothing appears on the serial port.
I have attached the serial output.
I am trying to figure out why it is happening.
Is anyone else seeing similar issues? Are there any suggestions on the
approach I can take to debugging this?
Thanks
Raj
