Hello,



If you look at parallelhashlist in:

http://pages.videotron.com/aminer/



Even if i use lock striping for the hash chains in parallelhashlist, 
synchronizing

access to the counter reintroduces the scalability problems of exclusive 
locking.

In this case, the counter is called a hot field because every mutative 
operation needs

to access it. So my next step is to split the global counter to many local 
counters...

also i am using a readewritelock in every chain, so my next step also is to 
lower

the number of readwritelocks to consume also less memory...



Thank you.

Amine Moulay Ramdane.

I mean to split the global counter to many counters to enhance the 
scalability...

Even if i use lock striping for the hash chains in parallelhashlist,
synchronizing access to the counter reintroduces the scalability
problems of exclusive locking. In this case, the counter is called

So my next step is to split the global counter to many counters to

I was speaking about the counter that computes the number of the entries in 
the hashmap
