Hi! Thanks in advance. Thanks to all of you who have responded to me on above. This is one of the responses I received on above.

Hi, I'm new to calling C++/C programs from R and am having some trouble getting started. Following Sigal Blay (Simon Fraser University)'s instructions, I have a .c file called "useC1.c": /* useC1.c */ void useC(int *i) { i[0] = 11; } This produces a .o file : "useC1.o" in a specified directory. I then open R, set the proper directory and:

I am trying to get the handytone 286 to make a very simple call to * and having problems. It registers with * just fine, but when I place a call (to echo test, for example), the RTP stream seems to have problems opening. Here is there error I get in *: WARNING[98311]: File chan_sip.c, Line 464 (retrans_pkt): Maximum retries exceeded on call 20d1c411-e210-5f3d-3f88-19035c8fcb26@192.168.2.6 for

Holding the vblk->lock across kick causes poor scalability in SMP guests. If one CPU is doing virtqueue kick and another CPU touches the vblk->lock it will have to spin until virtqueue kick completes. This patch reduces system% CPU utilization in SMP guests that are running multithreaded I/O-bound workloads. The improvements are small but show as iops and SMP are increased. Khoa Huynh

I noticed that R was burning up 100% of a CPU when a call to Sys.sleep() was made. Upon investigation, I discovered that R_checkActivityEx() in src/unix/sys-std.c was putting the entire timeout (in usec) into the struct timeval tv_usec member, leaving tv_sec set to 0. I don't know about other unix variants, but Solaris requires that the timeout value be normalized (i.e. 0 <= tv_usec

Hi, Jens & Rusty This version is rebased against linux-next which resolves the conflict with Paolo Bonzini's 'virtio-blk: allow toggling host cache between writeback and writethrough' patch. Patch 1/3 and 2/3 applies on linus's master as well. Since Rusty will pick up patch 3/3 so the changes to block core (adding blk_bio_map_sg()) will have a user. Jens, could you please
