[1.] Soft-Roce RDMA atomic operations multiple calls cause block [2.] I have downloaded the newest Soft-Roce version from github rdma-core and tested it on 3 machines. I followed the instruction on mellanox https://community.mellanox.com/docs/DOC-2184 and both the rdma_rxe module and the user space library seem correct. But I have a problem on atomic operations. If I call atomic operations in a loop for e.g. 200 times. Then somewhere in rxe.c the program will be blocked: #0 rxe_poll_cq (ibcq=0x8f246b0, ne=1, wc=0x7efb5ec41170) at /home/siqi/Downloads/rdma-core/providers/rxe/rxe.c:250 #1 0x00000000016a996a in pgaspi_ib_dev_wait () #2 0x00000000016a42f6 in pgaspi_wait () #3 0x0000000001432c31 in SuiApiGPI2::waitOnVMQueue(SUIQueue) () #4 0x0000000001430b32 in SuiApiGPI2::writeDMA(unsigned char*, unsigned long, unsigned char*, unsigned long, unsigned long, int) () [3.] Soft-Roce, RDMA, atomic operations [4.] Linux version 4.9.0-040900-generic (kernel@tangerine) (gcc version 6.2.0 20161005 (Ubuntu 6.2.0-5ubuntu12) ) #201612111631 SMP Sun Dec 11 21:33:00 UTC 2016 [5.] [6.] [7.] [7.1.] If some fields are empty or look unusual you may have an old version.
