[openfabrics-ewg] RE: Minor issues with resource tracking test

[Sharma, Karun]

Hi Dotan:
 
Thanks for your responses.
 
I am aware that we support [0..5] as MR TYPE. My point was that as we are generating an error when we execute with "-m 6" , we should also generate an error when we specify -m to any alphabet eg. "-m a". At present, "-m a" doesn't give any error and execute the test with default option for -m.
 
Thanks
Karun

You are absolutely right, this issue was fixed (the multicast short flag is now '-l').

> Moreover, -m option doesn't affect Multicast setting.  "-m YES" or "-m NO" doesn't switch on/off multicast. It execute the test with default MR Type and default Multicast setting.
You get this response because of the previous issue (same letter is being used for both options)

There are only several MR types that are being supported by the test ([0..5]).  please review the readme.txt for more details.

> One more thing, please let me know if there is any upper limit to -x (number of threads) option. It fails if i specify -x 20.
The value of X is multiplied by the number of objects, in your example 120 threads will be created in the machine, and everyone of them will try to create the number all the resources.
The limitations are the total number of threads that one process can open and the amount of memory that you have in your host.


Thanks
Dotan
