New Jan2014 stable branch created
by Sjoerd Mullender 27 Nov '13

27 Nov '13

I have created a new stable branch for the next feature release. This branch was created in order to stabilize the code before the feature release. From now on *only* bug fixes may go to this new stable branch. I reserve the right to undo any changes that do not comply with this rule. I also reserve the right to admit changes that are not strictly bug fixes. The name for the branch is Jan2014. So in each of your stable checkout directories you can do hg pull hg update -rJan2014 to update to this new branch. -- Sjoerd Mullender

MonetDB with OpenCL extension (Ocelot) query fails trying to cache empty BAT
by Edward Ching 25 Nov '13

25 Nov '13

I'm running into a problme with Ocelot, the MonetDB with OpenCL extension.Not sure if this should go to the developers' or users' list. I apologize if this is not the right list to post to. I'm seeing a query failure which was caused by MoneDB-OpenCL trying to cache an empty BAT and ended up calling clCreateBuffer with a 0 size buffer and failed. Any select with a where clause would trigger it. Has anyone seen this too? It fails whether I use 32 bit or 64 bit oid, Nvidia or AMD. I'm trying to figure if it's a real issue or if I'm missing anything. Any input greatly appreciated. The database was generated by TPC-H dbgen (details below). The query I used was "select c_custkey, c_name from customer where c_custkey < 2", and here's a trace of the sequence of calls leading to the failure starting from the MAL statement: 1) X_52 := ocelot.thetasubselect(r1_10,A0,"<",0);(see log below) 2) ocl_select.c::ocl_subselect() line 142: ocl_cacheBAT 3) ocl_memmanager.c::ocl_cacheBAT() line 771: allocateBuffer 4) ocl_memmanager.c::allocateBuffer() line 432: clCreateBuffer ===== Source version and environment ===== 1) Ocelot src installed from zip downloaded from monetdb-opencl: msaecker-monetdb-opencl-b513b35eb84a.zip 2) Ocelot configure options: ./configure --prefix=/usr/local --enable-oid32 --enable-optimize --disable-test ing --disable-developer --disable-debug --disable-assert --enable-sql --enable-m onetdb5 --with-opencl=/usr 3) Operating System: Fedora 17 kernel 3.9.10-100 4) Hardware: NVIDIA GTX570 on Intel i7-3820 w/ 16GB mem 5) OpenCL: Nvidia OpenCL that came with CUDA 5.5 SDK 6) Database: generated w/ TPC-H dbgen using size factor s=0.01 ===== operation log follows ===== [root@gen3-2 ocelot]# mclient -ddb001 -lmal mal>ocelot.init(); mal>ocelot.listDevices(); # Device 0: NVIDIA Corporation - GeForce GTX 570 (default device) mal>\q [root@gen3-2 ocelot]# mclient -ddb001 -lsql sql>\d TABLE sys.customer TABLE sys.lineitem TABLE sys.nation TABLE sys.orders TABLE sys.part TABLE sys.partsupp TABLE sys.region TABLE sys.supplier sql>\d customer CREATE TABLE "sys"."customer" ( "c_custkey" INTEGER NOT NULL, "c_name" VARCHAR(25) NOT NULL, "c_address" VARCHAR(40) NOT NULL, "c_nationkey" INTEGER NOT NULL, "c_phone" VARCHAR(15) NOT NULL, "c_acctbal" DECIMAL(15,2) NOT NULL, "c_mktsegment" VARCHAR(10) NOT NULL, "c_comment" VARCHAR(117) NOT NULL, CONSTRAINT "customer_c_custkey_pkey" PRIMARY KEY ("c_custkey"), CONSTRAINT "customer_c_nationkey_fkey" FOREIGN KEY ("c_nationkey") REFERENCES "sys"."nation" ("n_nationkey") ); sql>select count(*) from customer; +------+ | L1 | +======+ | 1500 | +------+ 1 tuple (1.311ms) sql>select c_custkey, c_name from customer where c_custkey < 2; +-----------+--------------------+ | c_custkey | c_name | +===========+====================+ | 1 | Customer#000000001 | +-----------+--------------------+ 1 tuple (1.776ms) sql>set optimizer='cl_pipe'; operation successful (0.981ms) sql>select c_custkey, c_name from customer where c_custkey < 2; invalid/unknown response from server, ignoring output ? #Could not allocate OpenCL buffer of size: 0.

Re: MonetDB: default - Prepare split of sql.mx
by Stefan Manegold 20 Nov '13

20 Nov '13

Martin, what's the (intended) difference between the newly added command mmath.rand{unsafe} (v:int) :int (see below) and the existing function mmath.rand{inline}( v:int ) :int; (see sql/backends/monet5/sql.mx line 1123) ? In particular, which of the two seemingly identical signatures will the MAL interpreter choose / use to evaluate, say, a:int:=mmath.rand(0:int); ? If they are identical / indistinguishable, one should be removed (again).

Default branch does not compile for builds with --enable_oid32
by Max Heimel 17 Nov '13

17 Nov '13

Hi, I stumbled upon a build error in the latest source from the default branch when I configure with --enable_oid32. The fix is a missing curly brace in the HASHputall macro at gdk/gdk_search.h:110.

Eleni, this calls for a proper configure check and conditionals to reduce/eliminate (extra) code maintenance overhead ;-) Feel free to ask in case you need more detailed pointers ...

Re: MonetDB: default - handle added types also in declared tables
by Sjoerd Mullender 11 Nov '13

11 Nov '13

Is this the fix for bug 3394 that you just closed? If so, was this really intended for the default branch (in which case the bug should be NEXTFEATURERELEASE) or should this have gone to the Feb2013 branch?

How do I get SQL decimal scale in MAL?
by Dru Nelson 11 Nov '13

11 Nov '13

HI, I"m working on writing an aggregate in in C that is a MAL function. I've run into a problem with decimal types. I've noticed that when I inspect the BAT inputs for various types, they are coerced to simpler types. (flt,dbl -> dbl). (int, decimal -> int). There is also no other information in the BAT structure to see the type. I notice that a SQL select gets the type info passed in as parameters for the 'exportValue' output. For example: >* sql.exportValue(1,".","second_single_value","decimal",9,3,8,_4,""); * How can I get this type information ('decimal', etc.) passed into my function? Dru

about "MT" in gdk module
by 张磊 06 Nov '13

06 Nov '13

hi all, I found that in gdk module of monetdb, the file gdk_posix.c has many functions which begin with “MT”, and I want to ask that what's "MT", is that "MoneT", "Multiple Thread" or others? what's the meaning of "MT"? :) -- Best Wishes! zhanglei

Monetdb ODBC datatype conversion problem
by baraa Mohamad 02 Nov '13

02 Nov '13

Dear MonetDB users, I have created a database link from oracle to monetdb using Monetdb ODBC driver, the link works fine but i have a strange results 😓 I have the following configurations: host1: Oracle (ubuntu 64bit)host2: MonetDB (ubntu 64bit)ODBC driver: MonetDB odbc (64bit) using unixODBC driver manager on monetdb i have the following table: emp (id integer , name varchar); test query: select id from emp where id<20; when I execute this query directly on montdb I get the following results (IDs from 1 to 19)ID123..19 BUT when I execute this query from oracle using dblink select "id" from "emp"@monetdb where "id"<20 ; I GET THE FOLLOWING RESULTS: ID-------- 18589934592 21.2885E+10 31.7180E+10 42.1475E+10 52.5770E+10 63.0065E+10 73.4360E+10 83.8655E+10 94.2950E+10 10 I cannot figure out the cause of the problem and how I can solve it (it seems a problem related to datatype conversion using ODBC) Could you please tell me what I should do.... Best regards,Baraa
