[ewg] Re: [ofa-general] Re: dapl attribute bug
Bug 1613 opened to track this. I think we need this for ofed-1.4.1. Steve. Steve Wise wrote: Hey Arlin, Did this ever get fixed? I think UNH is seeing this issue still. Steve Wise wrote: Davis, Arlin R wrote: The DAPL dat_ia_attr-max_lmr_block_size is a u32, yet the dapl code maps this to the linux ib_device_attr-max_mr_size which is u64. This causes dapltest to fail in some cases when running over chelsio which sets max_mr_size to 0x1 (4GB). The dapl code truncates the value to 0. See dapl/openib_cma/dapl_ib_util.c. I'm not sure what the fix should be, but maybe the dapl code should set anything over 32 bits to 0x? This attribute changed with DAT 2.0 to match the 32-bit ibv_sge length field. Since there are no direct max lmr segments mappings I will need add some checks when setting max_lmr_block_size from max_mr_size. Thanks. -arlin I'll test your fix when its ready. Lemme know.

Re: [ewg] OFED 1.4.1 RC4 is delayed to Thursday
Hi Tziporet. My update is that I believe I know what is causing bug 1607, and I'm working on a fix. Thanks. -jeff Steve Wise wrote: Status update: I cleaned up some NFSRDMA server crashes that happen when there are asynchronous WR failures. That might help Vu figure out 1571. I think there is a FW issue causing the async failure. But the code shouldn't crash anymore with my latest fix. But I'd also like 1613, 1616 into ofed-1.4.1: 1613: dapl regression that UNH uncovered. Arlin has a fix. 1616: nfsrdma ppc64 issue uncovered today. Hopefully we can nail this one by EOB friday Should we crank RC4 tomorrow and plan an RC5? Or hold off for a few more days with RC4? Steve.

I am running unit tests with the dapl fix (#1613) now and can have a new package later tonight.

Subject: Do you still need the local SA in OFED 1.5? The RDMA/IB CMs do not scale without PR caching or hard-coding PR parameters. I'm personally fine removing it from OFED. MPI and other applications are working around SA scaling issues by connecting over sockets anyway. ___ ewg mailing list ewg@lists.openfabrics.org http://lists.openfabrics.org/cgi-bin/mailman/listinfo/ewg
