Hello, I need migrate our applications from M-series to T-series. I would like compare two different SPARC processors - SPARCVII+ from Fujitsu and T5 from Oracle. I found only next benchmarks:
For comparing I choosed T5-2 which has 1/2 of T5-4 performance (410k/2 QphH) and same QphH performance as M8000:
So question is, if I will have full filled our M8000 box with 16 CPUs and migrate it to T5-2 Server, it will be enough for CPU performance?

HI,
I would like to know how to compare two files and replace non-matching lines with "_" .
I can get non-mathing lines with
grep -v -f file1 file2
i just want to knw how to display 'file2' with non-matching lines from 'file1' replaced by "_"

taskset
TASKSET(1) User Commands TASKSET(1)NAME
taskset - set or retrieve a process's CPU affinity
SYNOPSIS
taskset [options] mask command [argument...]
taskset [options] -p [mask] pid
DESCRIPTION
taskset is used to set or retrieve the CPU affinity of a running process given its pid, or to launch a new command with a given CPU affin-
ity. CPU affinity is a scheduler property that "bonds" a process to a given set of CPUs on the system. The Linux scheduler will honor the
given CPU affinity and the process will not run on any other CPUs. Note that the Linux scheduler also supports natural CPU affinity: the
scheduler attempts to keep processes on the same CPU as long as practical for performance reasons. Therefore, forcing a specific CPU
affinity is useful only in certain applications.
The CPU affinity is represented as a bitmask, with the lowest order bit corresponding to the first logical CPU and the highest order bit
corresponding to the last logical CPU. Not all CPUs may exist on a given system but a mask may specify more CPUs than are present. A
retrieved mask will reflect only the bits that correspond to CPUs physically on the system. If an invalid mask is given (i.e., one that
corresponds to no valid CPUs on the current system) an error is returned. The masks may be specified in hexadecimal (with or without a
leading "0x"), or as a CPU list with the --cpu-list option. For example,
0x00000001 is processor #0,
0x00000003 is processors #0 and #1,
0xFFFFFFFF is processors #0 through #31,
32 is processors #1, #4, and #5,
--cpu-list 0-2,6
is processors #0, #1, #2, and #6.
When taskset returns, it is guaranteed that the given program has been scheduled to a legal CPU.
OPTIONS -a, --all-tasks
Set or retrieve the CPU affinity of all the tasks (threads) for a given PID.
-c, --cpu-list
Interpret mask as numerical list of processors instead of a bitmask. Numbers are separated by commas and may include ranges. For
example: 0,5,8-11.
-p, --pid
Operate on an existing PID and do not launch a new task.
-V, --version
Display version information and exit.
-h, --help
Display help text and exit.
USAGE
The default behavior is to run a new command with a given affinity mask:
taskset mask command [arguments]
You can also retrieve the CPU affinity of an existing task:
taskset -p pid
Or set it:
taskset -p mask pid
PERMISSIONS
A user can change the CPU affinity of a process belonging to the same user. A user must possess CAP_SYS_NICE to change the CPU affinity of
a process belonging to another user. A user can retrieve the affinity mask of any process.
