[Sablevm-bugs] [ sablevm-Bugs-705868 ] multiprocessor crashes

From: SourceForge.net <no...@so...> - 2003-03-18 20:46:28

Bugs item #705868, was opened at 2003-03-18 15:58
You can respond by visiting: 
https://sourceforge.net/tracker/?func=detail&atid=105523&aid=705868&group_id=5523

Category: Execution Problem
Group: SableVM
Status: Open
Resolution: None
Priority: 5
Submitted By: Chris Pickett (cpickett)
Assigned to: Nobody/Anonymous (nobody)
Summary: multiprocessor crashes

Initial Comment:

SableVM still segfaults on a multiprocessor, even with
fixes for yield() and _svmf_set_current_env(). 
However, now execution completes 50% of the time.

Attached are parallel and non-parallel matrix multiply
benchmarks.

For non-parallel:

java matmul N

where N is the size of matrix

and for parallel:

java matmul_p N P

where P is the number of processors.

There are no problems on uniprocessors.

Cheers,
Chris

Note: I assume you already know that multi-processor support
is in SableVM's future enhancement list, not its current
feature list... :-)

It would be nice if you could identify the problem more
precisely.

I tested it and this was the _svmf_enter_object_monitor ()
bug fixed by r1596 in staging.
