Implementing new algorithm in Deuce

[Guy Korland]

Hi Guy,

I just tested my algorithm in Deuce and it didn't work. I got the
following error for every thread:

Exception in thread "Thread-1" java.lang.NullPointerException
at org.deuce.transaction.swisstm.Context.init(Unknown Source)
at org.deuce.benchmark.bank.Account.transfer(Account.java)
at
org.deuce.benchmark.bank.BenchmarkThread.step(BenchmarkThread.java:77)
at org.deuce.benchmark.BenchmarkThread.run(BenchmarkThread.java:
30)
at java.lang.Thread.run(Thread.java:619)


Can you tell me while this happens?
My code doesn't execute at all. I tried putting some print statements
both in the Context constructor
and as the first statement in the init method. None of them were
executed.
What's going on? Any help would be appreciated. Thanks.

I managed to start debugging my implementation with the tests, not the
benchmarks.
I found bugs in the read, write and commit methods but not in the
init.
I can go along without solving this problem, at least for the moment.
It's still weird though.

Can you post a test case?

I used the counters test provided in the framework.
This gave me more specific error messages and I could see the output of
my prints.
No errors in the init method, opposed to what the previous output would
indicate.

Mihai,

Sorry I lost you is there any problem?

Just that it's impossible to debug using the benchmarks.
Not even the print statements give output.
It's OK when using the tests.
