There is a rather serious race with copyout() and process termination in -stable. sysctl_kern_proc() loops through the allproc list writing the results to user memory. If it stalls during the copyout (e.g. the user memory has to take a vm_fault) and the process is ripped out from under it it will go looping into never never...

I'm porting the most recent version of Neil Provos' systrace to FreeBSD 5.1. I'm sending him the diffs to integrate into his distribution. I'd also like to submit them to someone with FreeBSD for consideration, and hopefully inclusion as a port or whatever you prefer. Who could I send them to, or what would you prefer me to do with regard to FreeBSD? Thanks, Rich Murphey

The PTX back-end is robust (it's based on the sources used by nvcc), but I'm not sure about the OpenMP representation in LLVM IR. I believe the OpenMP constructs are already lowered into libgomp calls before leaving DragonEgg. It's been awhile since I've loooked at it though. If you use the PTX back-end and have any issues, please don't hesitate to post to the list and cc:

Hi, Is it possible to translate an OpenMP program to CUDA using LLVM? I read that dragonegg has a OpenMP front-end and LLVM has a PTX back-end. I don't know how mature these tools are. Please let me know.

...ead entirely (ie the main thread blocked in pthread_join). This makes sense given that raise() only promises to target the process, not a given thread. Would it be possible to add an equivalent to lwp_kill() that specifically targets a thread? (I also tried setting a watchpoint using procfs, but copyout errors out instead of raising the thread-specific SIGTRAP I had hoped for...) Thanks, Ryan -- This message posted from opensolaris.org

Hello! The current MCA/MCE support in Xen is that it dumps the error and panics. In the following concept I propose here, there are two places where Xen has to react on. I) Xen receives a MCE from the CPU and II) Xen receives Dom0 instructions via Hypercall The term "self-healing" below is used in the sense of using the most propriate technique(s) to handle an error such as MPR

We are using MySQL, and love the idea of using zfs for this. We are used to using Direct I/O to bypass file system caching (let the DB do this). Does this exist for zfs? This message posted from opensolaris.org
