Does the Blackdown distribution and JVM for the AMD64 support heap spaces larger than 2GB?

2004-01-14 Thread Brian Hart

I'm looking for a java solution for the AMD opteron that will allow me to
write & run a java app that has a large heap of ~8-14GB.  Does your
distribution and JVM for the AMD64 support larger than 2GB heaps?  I know
that Sun will release a 64-bit version of Java in the summer of 2004 but
would like something sooner.

Also, does the implementation have a hashtable that uses 64 bit hashcodes?
Sun's 32 bit version has 32 bit hashcodes which is problematic due to the
increased likelyhood of collisions.

Thanks.

B Hart

I guess the answer is yes and you can find it in the archives :)

Re: re-compiling code with Sun's extended API's to run on Opteron

2004-01-14 Thread Brian Hart
I have a Java app. that uses some of Sun's extended API's such as JAXB and
web services.  I am wanting to know if it is possible to recompile this code
to run on an Opteron server with blackdown's JVM, and in a 64 bit mode with
larger heaps?

It should work without recompiling.
