After running out of swap and memory and freezing, a domU called web02 won't start up. Both dom0 and domU are running CentOS release 5.4. dom0's kernel is 2.6.18-164.el5xen and I'm running the stock xen from CentOS: xen-3.0.3-94.el5 After issuing 'xen create web02' I see the following in the xen console: Inode-cache hash table entries: 65536 (order: 6, 262144 bytes) vmalloc

From: Jyri Sarha <jsarha at ti.com> Semantics of inner_product_single have also been changed to contain the final right shift and saturation so it can also be implemented in the optimal way for the used platform. This change affects fixed point calculations only. I also added a new fixed point macro SATURATE32PSHR(x, shift, a). It does pretty much the same thing as SATURATE32(PSHR32(x,

Dear Admin, I will appreciate if you advise me an effective way to write the following R code including nested for loops. I cannot do it by using expand.grid function because it results with memory allocation problems. Thanks for your time and consideration. for(d1 in 0:n){ for(d2 in 0:n){ for(d3 in 0:n){ for(d4 in 0:n){ for(d5 in 0:n){ for(d6 in 0:n){ for(d7 in 0:n){ for(d8 in 0:n){ for(d9 in

Hi, I''m running Xen server based on OpenSuSE 11 (Xen version 3.2.1_16881_04-4.2). I have several Linux DomU''s that run perfect. Now I need a temporary Vista install (for testing) so I used ''virt-manager'' to install Vista. I used LVM based setup, Vista got 4GB of memory (at least temporary) and 2 CPU''s. Initially things look good - I get the console

I didn't read Nadav's reply as saying there was no bug, in fact he explicitly said in his email

Hello, Recently many advanced memory mechanisms are introduced into Xen. One problem we found is the conflict between p2m query and setting. For example, backend drivers always map domU’s page to its own space, during the mapping procedure, situations as follow may happen, when mfn is obtained by gfn_to_mfn(), this mfn is likely to be paged out. first case: grant mapping

Hi Duncan, I also thought it was a bug, especially since it worked with LLVM 3.0, but since it is not defined by ABI, I was not sure if I need to submit it as a BUG. I wanted to be sure that it is an actual BUG before submitting it and got the not-a-bug answer. Here is a small example to reproduce the problem I'm experiencing: ; ModuleID = 'bugparam.ll' target datalayout =

Dear mailing list, Genomics Medicine Ireland is opening new positions for our bioinformatics team. The team will analyse the ?omics data produced at GMI, which currently includes disease cohorts such as IBD, Multiple sclerosis, Alzheimer's, rare diseases, cancer and recently we have opened programs in diabetes and asthma. Our work will also focus on ancestry related topics, namely how

With the traditional qemu tree fixed to not use PROT_WRITE anymore in the mmap() call for this region, and with the upstream qemu tree not being capable of handling passthrough, yet, there''s no need to treat Dom specially here anymore. This continues to leave unaddressed the case where PV guests map the MSI-X table page(s) before setting up the first MSI-X interrupt (see the original c/s

Hi all, I’m not sure if this is the right list, so apologies if not. Doing some profiling I noticed some of my hand-tuned matrix multiply code with NEON intrinsics was much slower through a C++ template wrapper vs calling the intrinsics function directly. It turned out clang/LLVM was unable to eliminate a temporary even though the case seemed quite straightforward. Unfortunately any loads

Hi Keir: I am sorry trouble you again. I want to emulate instruction "push %ebp" in Xen. I found the function emulate_privilege_op does not satisfy this requirement. Then I resort to x86_emulate. I construct the x86_emulate_ctxt and reuse the "ptwr_emulate_ops". code like this: extern const struct x86_emulate_ops ptwr_emulate_ops; in do_general_protection { .... struct

Folks -- One more time with the PAE request, this time I''ve brought up the Linux kernel w/ a very recent version of Xen. (Just yesterday I pulled and updated my hg tree.)

Hello Renato, You're pointing me at ARM intrinsics related to loads, problem that I've reported in original e-mail, is not support for vector loads, but support for 'vmaxs'. For instance, there is no vector loads of 16 floats in ARM ISA but it is legal to write in LLVM: ; ModuleID = 'vadd.ll' target datalayout =

Hi Andy, thanks for your help!! The scheduled code by method A is same as B when using the new machine model. it's make sense, but there is the another problem, the scheduled code is badly. load/store instruction always reuse the same register Source: #define N 2000000 static double b[N], c[N]; void Scale () { double scalar = 3.0; for (int j=0;j<N;j++) b[j] =
