Vritualization with Parallels for MacIntel

Hi,
I came across of review of the Virtualizaiton Solution for intel macs and wanted to give it a go.
http://www.parallels.com/en/products/desktop
I was wondering if someone knows how secure it will be to running WindowsXP on it in regards to worms and viruses?
Thanks.

That is correct but your question did not state that you were concerned about the OS X portion but asked if you would have the same issues with viruses and such. On the Windows partition you will, on the OS X partition you would only have the same issues you have now. If you sent an infected virus for instance with your windows based email application and received it on your OS X partition with its email application then it would not run since OSA X could not do anything with it. However, you could pass that virus on via email just as you can now.
The easiest way to think of this is to think of two totally separate systems and treat each as such. Any windows problem that you can experience now, you could have on the windows partition. It won't affect the OS X partition though.
If you have an OS X issue, then it won't affect the windows partition.

C# - Excel Interop (Parallel.For)

Hi All,
I had a Excel Macro which i converted into C#. (Interop) It has 5 different methods for some calculations for report creation.
2 method out of these are running very slow due to complex calculation. (10 minutes each for 40 mb data)
After checking these methods, I found that there are few "FOR" loops which takes the time. (It iterate each row in sheet and do some calculation for each cell in row)
After some searching, i found that i can use "parallel.For" loop for enhance performance.
But Thread throws error "Exception from HRESULT: 0x800AC472". After searching
i found that it because of STA.
Any pointers for better performance with C# to Excel (Interop) parallel programming would be helpful.
Thanks.
Thanks & Regards, Rakesh Parmar

Perhaps you will be also interested in one more optimisation approach. Instead of reading each cell separately, you can transfer a larger range (the entire filled row, or even all of the needed rows) into an array, such as
‘object [,] data = (object [,])someRange.Value2’. Then use this bi-dimensional array. See:
http://www.bing.com/search?q=c%23+increase+excel+performance+range+array.
You can probably also create several Threads manually (if
Parallel.For cannot be used) and control the AppartmentState property. Or process the previous array in parallel with threads or with
Parallel.For.

Windows XP or Vista for use with Parallels on MacBook 2.16 GHz?

As described in my earlier post, I'm currently switching from my G4 PowerBook to a new MacBook 13" 2.16 GHz.
I'll have to use Windows parallel to OS X (plan to do that with Parallels Desktop) and would like to know what you recommend:
Windows XP or Windows Vista?
Vista should be better in security issues, however it should also consume much more ressources and thus run slower ... is that right?
What's your experience?
Martin
MacBook 2.16 GHz, 2 GB RAM, 120 GB HD (white) Mac OS X (10.4.9)

Hi Martin,
personally I favour XP over Vista (at least for now and the near future), because as you mentioned Vista a much more hungrier than XP and also because there are still a lot of applications which do not work correctly or at all in Vista.

I have an imac bought late 2013, can i use it as a display for the new mac pro? I also want to use windows 8 on it, would this work with parallels or bootcamp?

I have an imac bought late 2013, can i use it as a display for the new mac pro? I also want to use windows 8 on it, would this work with parallels or bootcamp?

Yes, it supports target display mode. Windows can be run with either Parallels or Boot Camp.

Pointers for optimizing system performance (run time) while running DP process chain with parallel processing

Hi Experts,
We are running APO DP process chain with parallel processing in our company, we are experiencing some issues regarding run time of process chain, need your help on below points;
- What are the ways we can optimize process chain run time.
- Special points we need to take care of in case of parallel processing profiles used in process chain.
- Any specific sequence to be followed for different processes in process chain - if there is some best practice followed.
- Any notes suggesting ways to improve system performance for APO version 7 with different enhancement packs 1 and 2.
Any help will be really appreciated.
Regards

HI Neelesh,
There are many ways to optimize performance of the process chains (background jobs) in APO system.
Firstly I would recommend you to identify the pain areas (steps) which are completing with more runtimes. Then each one of the step has got different approaches to decrease the runtime.
Like you may end up with steps like infopackage executions, DTPs, DP mass processing jobs etc which might be running with more runtimes. So now target each one of them differently and find out the ways to optimize. At the same time the approach you follow should be technically possible with basis perspective (system load and utilization) as well.
And coming to parallel processing, you can use parallel processing for different for different jobs. You can further r explore on the same using parallel processing. Like loading an infocube, mass processing, infopackage execution, DTP, TSCOPY etc.
Check the below link for more info
Performance problems in DP mass processing
Let me know if you require further info.

Parallel ledger with values for past period

hi
we are creating addl ledgers with different fiscal year variant
is it possible for me to fill up this ledger with values for a past period?
my fiscal year variant is V3 April - March, however I need the parallel ledger for calender year Fiscal Yr Variant K4.
Going live with this in april is it possible to populate this ledger with values for jan-march period
regards
sameer

HI,
I am not sure if it is helpful but what you can do is to define an asset movement type limited to a valuation area, which allows you to post for example acquisitions only in on valuation area, but not in the other one.
Thus you can post ABSO with one asset movement type for one valuation area (APC-value X) for another valuation area use another movement type and post APC value Y.
Anyway the difference of the APC value (thats not ativated) needs to be posted to an P&L account.
Maybe there are other/better suggestions from other people.
Best regards, Christian

No dhcp for airport with parallels

hi,
i have a macbook and installed parallels yesterday. since i rebooted the mac, my airport can not get an address from dhcp. it only has a self assigned ip address. when i first ran paralles i chose bridged network. but now it makes no difference which network option i choose in parallels. there is no ip from dhcp for airport anymore. the ethernet card still works fine. but i`m afraid that once i use it with parallels the same thing will happen to it. anyone got an idea what to do about that?
greetz,
mike

Hi, Mike / James Hetfield.
I don't mean to send you somewhere else, but this is a question you need to address with Parallels Support. I presume you've reviewed the Parallels User Guide concerning DHCP.
You might also want to search the AirPort & AirPort Express Discussions in case it has been addressed there, where AirPort-related questions are answered.
Good luck!

Adobe creative cloud set up to install on a mac with parallels windows 8

Unfortunately it is not possible to install the program it always displays an error message. how can you loess the problem?
error message: This application can not be run from a network drive-. copy it to a local folder and strarten it again.

I have just the regular version, not Professional.
I mean "les integrated", in the sense that you really run Fusion "in a window". The more "integrated" approach means that Windows applications run as if they were for the Mac, and you do not see the Windows interface at all. I personnaly think tjat is too confusing. There is nothing wrong with it, just a bit more confusing. i like having it clear that Windows is in a seperate Window.

Help with parallel arrays of different data types

Hello all, I am having an issue with parallel arrays. My program requires me to read information from a text file into 4 parallel arrays (2 String and 2 double). My text file needs to look something like this:
John Johnson
0000004738294961
502.67
1000.000
Jane Smith
0000005296847913
284.51
1000.000
...and so on
Where the first thing is the name (obviously), an account number, the balance in the account, and the credit limit. I just cant figure out how to read everything into the arrays. We havent learned anything too heavy, and this seems a little too advanced for my class, but I guess we will manage. Any help will be appreciated. Thanks guys.
Casey

Man this is a dumb homework assignment. The requirements scream out for a class along the lines of
public class Account{
private String name, number;
private double balance,creditlimit;
// more code here
}and then to use a List of Account objects.
Anyway what's your actual problem. There's nothing very hard about it. A loop. So....
You should consider posting (formatted) code showing what you have done and where exactly you are stuck.

Multi-table INSERT with PARALLEL hint on 2 node RAC

Multi-table INSERT statement with parallelism set to 5, works fine and spawns multiple parallel
servers to execute. Its just that it sticks on to only one instance of a 2 node RAC. The code I
used is what is given below.
create table t1 ( x int );
create table t2 ( x int );
insert /*+ APPEND parallel(t1,5) parallel (t2,5) */
when (dummy='X') then into t1(x) values (y)
when (dummy='Y') then into t2(x) values (y)
select dummy, 1 y from dual;
I can see multiple sessions using the below query, but on only one instance only. This happens not
only for the above statement but also for a statement where real time table(as in table with more
than 20 million records) are used.
select p.server_name,ps.sid,ps.qcsid,ps.inst_id,ps.qcinst_id,degree,req_degree,
sql.sql_text
from Gv$px_process p, Gv$sql sql, Gv$session s , gv$px_session ps
WHERE p.sid = s.sid
and p.serial# = s.serial#
and p.sid = ps.sid
and p.serial# = ps.serial#
and s.sql_address = sql.address
and s.sql_hash_value = sql.hash_value
and qcsid=945
Won't parallel servers be spawned across instances for multi-table insert with parallelism on RAC?
Thanks,
Mahesh

Microphone on Macbook pro does not work in windows 7 with parallels

I recently purchased a Macbook pro with retina display, and installed windows 7 on the macbook with parallels desktop 7. I found out my microphone was not working correctly inside windows, I did bought my laptop to Apple store, at first we thought it was the microphone problem and exchanged me a new laptop, but the issue still exits, so I bought the laptop back to Apple store, this time we find out it seems like the microphone only not working under the windows, it works just fine in Mac part.
Apple direct me to windows telling me that I might need to install a device or driver only windows can provide; then when I contacted window, Windows told me I need to contact apple because the device or deriver must provided by the manufacture of the PC. Both side still direct me back to each other, so I still don't know what deriver or device I needed..........
When I pull up the device manager inside windows, the only device listed under sound is "Parallels Audio Controller (x64)"
Another thing is, the microphone still works inside windows 7, it's just not working correctly. For an example, if I'm doing a live chatting with my friends inside windows, I can hear my friends and they can hear me too, but they cannot hear me very clearly, it seems like there are some kind of negative feedback, it seems like there's an electronic vibrate in my voice.
Can someone please help me
Thank you

How to code a parallel 'for loop' and 'while loop' where the while loop cannot terminate until the for loop has finished?? (queues also present)

I've attached a sample VI that I just cannot figure out how to get working the way that I want. I've labeled the some sections with black-on-yellow text boxes for clarity during the description that follows in the next few sentences. Here's what I want:
1) overall -- i'm intend for this to be a subVI that will do data acquisition and write the data to a file. I want it to use a producer/consumer approach. The producer construct is the 'parallel for loop' that runs an exact number of times depending on user input (which will come from the mainVI that is not included). For now I've wired a 1-D array w/ 2 elements as a test case. During the producer loop, the data is acquired and put into a queue to be delt with in the consumer loop (for now, i just add a random number to the queue).
2) the consumer construct is the 'parallel while loop'. It will dequeue elements and write them to a file. I want this to keep running continuously and parallel until two conditions are met.
      i. the for loop has finished execution
      ii. the queue is empty.
   when the conditions are met, the while loop will exit, close the queue, and the subVI will finish. (and return stuff to mainVI that i can deal with on my own)
Here's the problems.
1) in the "parallel for loop" I have a flat sequence structure.. I haven't had time to incorporate some data dependency into these two sequential sections, but basically, I just care that the "inner while loop" condition is met before the data is collected and queued. I think I can do this on my own, but if you have suggestions, I'm interested.
2) I can easily get the outer for and while loops to run sequentially, but I want them to run in parallel. My reasoning for this is that that I anticipate the two tasks taking very different amounts of time. .. basically, I want the while loop to just keep polling the queue to get everything out of it (or I suppose I could somehow use notifiers - suggestions welcome)... the thing is, this loop will probably run faster than the for loop, so just checking to see that the queue is empty will not work... I need to meet the additional condition that nothing else will be placed in the queue - and this condition is met when the for loop is complete. basically, I just can't figure out how to do this.
3) for now, I've placed a simple stop button in the 'parallel while loop', but I must be missing something fundamental here, because the stop button is totally unresponsive. i.e. - when I press it, it stays depressed, and nothing happens.
suggestions are totally welcome!
thanks,
-Z

I'd actually like to add a little more, since I thought about it a bit and I'm still not quite certain I understand the sequence of events...

So i read a bit more about the 'dequeue element' function, and as I understand it, since there is no timeout wired to the dequeue element function, it will wait forever, thus the race condition I suggested above can never happen!
Yes, you got it!
As I've thought about it a bit more, there's a few things that surprise me... first, the reason the 'dequeue element while loop' errors is not because there's nothing in the queue, it's becaues the queue has been released and it's trying to access that released queue... However the problem I have is this --- Even though there's no timeout wired to the dequeue element, I still would think that the while loop that contains it would continue to run at whatever pace it wanted -- and as i said before.. most of the time, it would find that there is nothing to dequeue, but once in a while, something is there. however, it seems that this loop only runs when something has been enqueued. the reason I say this is illustrated in the next code sample MODv2 that's attached below. I've added a stop button to the "queue size while loop" so the program runs until that is pressed. I've also added a simple conditional in the "dequeue while loop" that generates a random number if it a button is pressed... but this button is totally non-responsive... which means to me that the "dequeue while loop" isn't actually continuously running, but only when an element is added to the queue. this still seems almost like the 'dequeue while loop" waits for a notifier from the queue telling it to run. can you explain this to me? because it is different from what I expect to be happening.

How to run the same procedure in parallel for different parameter value.

Hi There,
I am currently working on extracting data in to flat file and I am able to do so for one revenue month (e.g. 200101) using PL/SQL procedure(get_rev_data). it takes almost 1 hour to execute the procedure completely and it generates 400 MB data file. Now I have to run this procedure for last 10 yrs of data (i.e. 120 revenue months) . my prolem here is to figure out a way/logic in such a way that I can run the procedure in parallel for each revenue month and at the same time it will write the data in respective data file for each revenue month. so the final result of this exercise would be 120 flat files, one for each revenue month with file names like
EXTRACT_00001001 to EXTRACT_00001120.
where
first five digits : 00001 will indicate the Extract run number and
last three digits : 001 will indicate the thread number for each run.
I am thinking of doing this by creating a table "RevMonth" with two values (revenue_month, thread_num) and calling the procedure in a simple select statement and passing revenue_month as parameter of the procedure like
SELECT get_rev_data(revenue_month, thread_num)
FROM REVMONTH;
But I am not sure if that will do the needful. Any idea on how to achieve this will be of great help. Thank you.

Hi Smit,
Thanks for the advise. I am not planning to run for all 120 months at once. actually I am planning to run like 1 year (12 revenue months at a time). I am not sure if that will work well but I was planning to run this through shell script (Unix) and will call the same procedure with different parameter (revenue_month and Thread_number) values and see what happens. I hope that will run in parallel for each revenue month.
Let me know if you have more knowledge about it. THanks a lot.
Thanks,
.

Trying to install on MacBookPro with Parallels and Windows 8.1. Downloaded the CreativeCloud.exe but says I can't install from network drive

I sometimes like to use Photoshop CC and Lightroom on the Windows side of my MacBookPro with Parallels. I had to reinstall Parallels and also Windows 8.1 recently and am trying to reinstall some of the software that I had previously on the Windows side. I downloaded the CreativeCloud.exe program and when I try to install it from the Windows side, get a message that I can't install Creative Cloud from a network drive. Where can I put the CreativeCloud.exe so I can install it?
Thanks!

You probably need to check your drive setup for the Parallels environment. Nothing to do with Adobe.
