Compiling Bonnie is extremely simple, but requires you to install make and GCC (or cc)
# makeoptions are ' make BSD ' and ' make SysV '-The default is ' BSD '. If you are messages about m
Environment
Operating System: win7, 64bit
IDE: CCS v3.3
Simulator: Seed xds510plus
DSP model: tms320c6713gdp (dsp6713)
Check Procedure
Try to press the reset button and then click Connect connection
Check whether the power supply is normal (whether the core voltage is 1.2 V, and whether the I/O port voltage is stable at 3.3 V)Use the oscilloscope AC to test and check the ripple of the power supply. Page 99 of the tms320c6713 Data Manual requir
future convenience. Most of the time, we make the corresponding format and connect it to 0000.4. # vgcreate/dev/vg02/dev/DSK/c0t3d0/dev/DSK/c0t4d0Note: This command is used to create vg02 and include c0t3d0 and c0t4d0. Of course, you can also include a hard disk and then expand the second hard disk as needed, the procedure is as follows:# Vgcreate/dev/vg02/dev/DSK

Automatically generate Emcpower, never heard of it.
1. Install the EMC host Base agent on the client
Mount-f Cdfs-o Cdcase/dev/dsk/c0t0d0/cdrom
(only such mount can read the correct EMC disc)
Swinstall-s/cdrom
2. Build RAID group on EMC Manager Server (Group 3)
3. Building LUNs on RAID group (LUN 8)
4. Build a new storage Group (JS-WAP01)
5. In storage Group (JS-WAP01), add JS-WAP01 to the hosts (right-click js-wap01--> attrib
TI corporation as an example, this paper introduces a new method of secondary bootloader with interrupt vector table, this provides a new idea for the development of the TMS320C6000 series DSPs. This method is applied in practice, and the system runs stably and reliably.

Tms320c6713 is TI's latest floating point DSP of the tms320c67xx series. Tms320c6713 can execute 8 32-bit comm
Back up all data on the local disk to tapeBy default, you do not need to specify the file system device number. The value is "/dev/RMT/0 m ". However, if this device does not contain tape media or you need to apply other devices, you must add the parameter "-d" and specify the device number.

In general, the USB stick can be automatically identified, if not automatically recognized, you can try the following methods:
Run Volcheck First/etc/init.d/volmgt stop/ETC/INIT.D/VOLMGT startVolcheck
If this still doesn't work, it's going to be hooked up with mount.
Devfsadm-c diskcd/dev/dsk/Ls-lYou can see the USB device connectionThen Mount-f Pcfs/dev/dsk/cxtxdxsx/usb.
First, verify that the file format

Calculation of Lun numbers commonly used by HP:For example, the name of a disk device is/dev/DSK/cxtydz.
Lun id = y * 8 + z
-----------------------------------------------------
Thousands of targets are troublesome. Because a SCSI link can only have 15 targets, the Y value of/dev/DSK/cxtydz can only be up to 15, that is to say, the maximum Lun number on a SCSI link is/dev/

If you want to create a boot disk image, refer to the "root disk image" section.
After the hard disk is initialized, you can add the PV to an existing VG: # vgextend vg01/dev/dsk/c0t5d0 # vgdisplay-v vg01
Note that during hard disk initialization (pvcreate/dev/rdsk/c0t5d0), the device used is "rdsk ", when adding a PV to an existing VG, the device used is "dsk ".

Now srs2.0 single-process one-way network throughput can reach 4Gbps (6,000 client, bit rate 522Kbps), go if not to achieve this goal, then SRS can not be rewritten with go.

The test on the 24CPU server, the CPU is not a bottleneck.
The test uses the LO network card, direct memory copy, and the network is not a bottleneck.
When both the CPU and the network are fully resourced, the execution speed of the server itself is critical.
