Basically, I want to copy all files (F03*) in this directory and merge/paste them into a new file (called SMER_2.03.12.SPU), yet the error message is "no such file or directory." I listed what is in my working directory, and the files do exist, so I'm not sure what's going on. The code's at the bottom.*
Thanks, Ellen

I am trying to build a tuxedo server which in turn depends on several Pro*C programs. I am doing it on HP-UX system.
It looks to me that the ORACLE_HOME is set properly.
But I am getting error message when trying to build.

Hello all, I have a question about creating a script that will look for messages on one of our MQ series systems, and fix them.
Currently, if we issue a command for example

spu_run
SPU_RUN(2) Linux Programmer's Manual SPU_RUN(2)NAME
spu_run - execute an SPU context
SYNOPSIS
#include <sys/spu.h>
int spu_run(int fd, unsigned int *npc, unsigned int *event);
Note: There is no glibc wrapper for this system call; see NOTES.
DESCRIPTION
The spu_run() system call is used on PowerPC machines that implement the Cell Broadband Engine Architecture in order to access Synergistic
Processor Units (SPUs). The fd argument is a file descriptor returned by spu_create(2) that refers to a specific SPU context. When the
context gets scheduled to a physical SPU, it starts execution at the instruction pointer passed in npc.
Execution of SPU code happens synchronously, meaning that spu_run() blocks while the SPU is still running. If there is a need to execute
SPU code in parallel with other code on either the main CPU or other SPUs, a new thread of execution must be created first (e.g., using
pthread_create(3)).
When spu_run() returns, the current value of the SPU program counter is written to npc, so successive calls to spu_run() can use the same
npc pointer.
The event argument provides a buffer for an extended status code. If the SPU context was created with the SPU_CREATE_EVENTS_ENABLED flag,
then this buffer is populated by the Linux kernel before spu_run() returns.
The status code may be one (or more) of the following constants:
SPE_EVENT_DMA_ALIGNMENT
A DMA alignment error occurred.
SPE_EVENT_INVALID_DMA
An invalid MFC DMA command was attempted.
SPE_EVENT_SPE_DATA_STORAGE
A DMA storage error occurred.
SPE_EVENT_SPE_ERROR
An illegal instruction was executed.
NULL is a valid value for the event argument. In this case, the events will not be reported to the calling process.
RETURN VALUE
On success, spu_run() returns the value of the spu_status register. On error it returns -1 and sets errno to one of the error codes listed
below.
The spu_status register value is a bit mask of status codes and optionally a 14-bit code returned from the stop-and-signal instruction on
the SPU. The bit masks for the status codes are:
0x02 SPU was stopped by a stop-and-signal instruction.
0x04 SPU was stopped by a halt instruction.
0x08 SPU is waiting for a channel.
0x10 SPU is in single-step mode.
0x20 SPU has tried to execute an invalid instruction.
0x40 SPU has tried to access an invalid channel.
0x3fff0000
The bits masked with this value contain the code returned from a stop-and-signal instruction. These bits are valid only if the 0x02
bit is set.
If spu_run() has not returned an error, one or more bits among the lower eight ones are always set.
ERRORS
EBADF fd is not a valid file descriptor.
EFAULT npc is not a valid pointer, or event is non-NULL and an invalid pointer.
EINTR A signal occurred while spu_run() was in progress; see signal(7). The npc value has been updated to the new program counter value
if necessary.
EINVAL fd is not a valid file descriptor returned from spu_create(2).
ENOMEM There was not enough memory available to handle a page fault resulting from a Memory Flow Controller (MFC) direct memory access.
ENOSYS The functionality is not provided by the current system, because either the hardware does not provide SPUs or the spufs module is
not loaded.
VERSIONS
The spu_run() system call was added to Linux in kernel 2.6.16.
CONFORMING TO
This call is Linux-specific and implemented only by the PowerPC architecture. Programs using this system call are not portable.
NOTES
Glibc does not provide a wrapper for this system call; call it using syscall(2). Note however, that spu_run() is meant to be used from
libraries that implement a more abstract interface to SPUs, not to be used from regular applications. See <http://www.bsc.es/projects
/deepcomputing/linuxoncell/> for the recommended libraries.
EXAMPLE
The following is an example of running a simple, one-instruction SPU program with the spu_run() system call.
#include <stdlib.h>
#include <stdint.h>
#include <unistd.h>
#include <stdio.h>
#include <sys/types.h>
#include <fcntl.h>
#define handle_error(msg)
do { perror(msg); exit(EXIT_FAILURE); } while (0)
int main(void)
{
int context, fd, spu_status;
uint32_t instruction, npc;
context = spu_create("/spu/example-context", 0, 0755);
if (context == -1)
handle_error("spu_create");
/* write a 'stop 0x1234' instruction to the SPU's
* local store memory
*/
instruction = 0x00001234;
fd = open("/spu/example-context/mem", O_RDWR);
if (fd == -1)
handle_error("open");
write(fd, &instruction, sizeof(instruction));
/* set npc to the starting instruction address of the
* SPU program. Since we wrote the instruction at the
* start of the mem file, the entry point will be 0x0
*/
npc = 0;
spu_status = spu_run(context, &npc, NULL);
if (spu_status == -1)
handle_error("open");
/* we should see a status code of 0x1234002:
* 0x00000002 (spu was stopped due to stop-and-signal)
* | 0x12340000 (the stop-and-signal code)
*/
printf("SPU Status: 0x%08x
", spu_status);
exit(EXIT_SUCCESS);
}
