Hi Team,
How do you compare Ignite data & compute grid components to OpenMP / MPI?
can you please call out the pros and cons of the two frameworks?
Thanks,
Arthi

I don’t anticipate any performance drop if you turn on the metrics. The
flag to enable metrics is there mainly for historical reasons.

Hi,
It creates the 'libs' folder. And I got imported the above project also that
you mentioned, but it's still showing the same result! :(
Also, to let you know, I'm using cygwin on a windows platform to run the
script, could that be any reason for it to not run?

There are several options how you can deal with this:
1) define caches in Spring XML configuration of all server nodes and start near
caches on clients when needed;
2) start a special client that will initialize all required caches dynamically
and stop it after that. The rest of the clients can
In addition if you want to place your libs to some other path on your machine
you’re free to do this and only need to add the libs from the path to the
classpath of a Java process that starts Ignite.
However the simplest way as Alexei referred is to add the libs to
“ignite_bundle”/libs folder a
Hi, I’m trying to load tSV file size ~six gigabytes (contains ~90 million
records) into single Apache Ignite node with allocated heap size = 40
gigabytes. For loading used IgniteDataStreamer. Code and sample (10

does write behind work without this setting :-
cacheCfg.setWriteSynchronizationMode(CacheWriteSynchronizationMode.FULL_ASYNC);
Here is my cache setting :-
cacheCfg.setReadThrough(true);
cacheCfg.setWriteThrough(true);
cacheCfg.setWriteBehindEnabled(true);
I undrestand that WriteAll will be called per cache.
But my undrestanding is this :-
1) There are two configs for write behind 1) No of Entries and Time
2) SO if I make three cache entries in three transaction before the time
(which is configured to lets say 4000 ms ) then the writeAll should b
Hi, what exactly is not clear?
When you create objects in Java, they end up on JVM heap, in managed
memory. These objects are subject to automatic garbage collection.
Ignite Off-Heap Memory feature stores cache data in unmanaged memory
(manual allocation/deallocation, like you do in C and other un
Hi,
Please clarify what are you trying to achieve?
>From logs I see the Ignite grid instance tries to start several times.
Please check the ServletContextListenerStartup class
for example how to correctly start Ignite in the servlet environment:
https://github.com/apache/ignite/blob/master/module
You can't have on the client node "far" and "near" cache simultaneously.
The error message you get on the attempt is pretty self-explanatory.
So I see not bug here.

Yes, removing definition of the cache from IgniteConfiguration, helps. And I
know about this.
The point was that I wanted for the client to be self sufficient, i.e. to
create all the distributed server caches first (by providing cache
definition for IgniteConfiguration), and then configure the nea
Hi,
In order to start clint node you should just execute code like this:
Ignition.setClientMode(true);
Ignition.start();
In this case client node with default configuration will be started. Of
course you can provide own IgniteConfiguration programatically:
IgniteConfiguration cfg = new IgniteCo
Hello,
Could someone explain this in simpler way ? Maybe some intuition ?

Put all your jars into lib folder if you are using standalone Ignite
distribution.
When you can provide your own config file as described here[1]

You should remove definition of the cache from IgniteConfiguration:

Ignite client = Ignition.start(igniteConfiguration);

client.getOrCreateNear

Hi Vladimir...Yes that is correct. I 1.6 binary that I downloaded from the
Jenkins server did not have your change. However 1.6 source I downloaded
from git branch has your change. I am building that and see if I can get
rid of the error.
Thanks,
Murthy.

Hi!
We have an open issue for this:
https://issues.apache.org/jira/browse/IGNITE-369
For now the only way to enable cache metrics - via configuration on cache
startup.
You may watch issue IGNITE-369 in JIRA and will be notified when it will be
fixed.
But I'm afraid it will not be fixed in nearest
So, it is not recommended to turn them on in production?
Then how you measure you cache overall behavior?
Could be it controlled over JMX?

Yes, cache metrics not work by default for performance reason. You can
enable it throught cache configuration property
javax.cache.configuration.MutableConfiguration#setStatisticsEnabled (or into

Yes, Ignite support full Spring configuration file. In my opinion, property

If you have example where it not so, please provide your source code.
